TT was not the fault of Mr. J. P. Malla­.!. lieu's Department that he was late inturning up to open the National Cham­pionships: he is Minister of State for theBoard of Trade. but the traffic ,iam atAscot which delayed him on Saturday.20th May. was the responsibility of theMinistry of Tramport. However. AnnWelch was at last able [0 announce thatthe Minister was "on his final glide.3;\- minutes out".

As he came to rest alongside the Hi,llhTable in the big marquee. Phil-ip Willsexplained that, among the ships andtrade and other things the Minister wasresponsible for. somewhere in a far topcorner was Gliding: he would, in fact.see a glider "which will put up ourexports a bit",

Mr. MaUalieu explained tbat amongthe things he did not control was notonly traffic but the weatner, He did noteven control glidinj:. apart from navingto settle disputes with ATe: gliding. hesaid, "is controlled by the British GHdinj:Association, that wonderful body ofgenuine amateurs", But one subject forwhich he had special responsibility wasaircraft noise (laughter).

Mr. MaHalieu then presented theChurchill Award to John Simpson. whointends to use it to study the sea-breezefront: he will make a film and observethe phenomenon from a two-seater sail­plane as well as from the ground.

The Minister having declared theChampionships open, Ann Welch tookover to the strain of "Happy Birthdayto Yeu". and proceeded to explain thenew "Cat's Cradle" distance task-orrather, advised everyone to tackle thetask of reading the small print of the

Rules. As usual with new rules. therewere ways of frustrating their intention,and she added: "I've discovered a lotof gamesmanshjp, but I'm not telling."She warned everyone that, as last year.the borders of controlled airspace wouldbe patroUed; then welcomed DickSchreder. who had come from Americato fly an HP-14 hors concQurs (applause).

The weather was unsuitahle for settinga task at present, but there would beanother brie.fing at 1 p.m., and mean­while "Pat Menmuir will give you a briefrun-down on the gales".

The wind, Pat said. was blowinl! 20-25

We were sorry to hear that HaroldDrew, vice-cl1airman of the Champion­ships organisation, was away ill withjaundice.

The J p.m. briefing was postponed to2.30 and that in turn was cancelled. Twoor three thunderstorms passed over in theafternoon. and Dick Schreder managedto soar under the base of one cu-nim.

Changes iD EDtry List .As usual. there were alterations in thIS

list after the version published in ourlast issue (I'. 202-3) had gone to Press.The corrections have been incorporatedin the Final Result (pag~ 290, 291).

Sunday, 21st May

At the 09.30 briefing the forecast wasnol very promising. A depression was toreach Ire/and by midday.. crossitrg theBritish Isles during the next 24 hours,with a warm front approaching from theS.W. Winds 200 0 15-20 knots. backillgand tending to freshen. 8/8 strato-wturning into cumulus by mid-morning.By 10.30 cloudbase was expected to riseto 2,000-2,500 ft. (a/l heights a.s.I.), topsto 5,000-6,000 ft., wilh modemte brokentherm!1ls. A slight impuwemellt was P()!i"

sible during the next hour bur cloudwould increase again and rain was ex­peJ::ted to reach Las/wm between 13.00­1400 hrs. Along the route condilionswould improve, with a chance of showersin East Anglia. but these wouid be fewand far between.

With this difficult weather situation itwould be necessary to get pilots away assoon as conditions would aItow. Aftergoing through the essential details ofbriefing quickly Ann Welch set a raceto Swanton Motley via Thame airfield,total distance 233.5 km. X=30 km., Y=66 km. Designated start. This task was

Page 7: Sailplane & Gliding 1967

set for League I, and the same task, ifany, for League 2 if their launch wasnot held up too long by relights forLeag\le 1 (League 2's task was subse­quently cancelled at 13.30).

As nobody had bothered to rig befor,ebriefing, there was now a frantic hurryto get ready-rather reluctantly-to beon the grid by 10.30. Pilots scarcely be­lieved that they might have to take theair as they waited patiently on the gridand watched the unpromising sky rushby. The "snifter", however, did not cQmedown as fast as they all expected, andev-en reported finding 3 knots lift overAlton at 1.500 ft. Obviously as sOOn asc1Qudbase reached 2,000 ft. they wouldbe sent on their way. Just before noonthe order to launch was given and the1967 Nationals had begun.

Towing was not easy, nor was itpleasant, as the air was extremely turbu­lent, but the tug piiots did a very goodjo.b and 38 minutes later the 42 glidersof Lea~u~ I had all been hauled into theair. Iohn Williamson had a bit of amishaJ) on take-o.tf with his HP-14 (des­cribed by him elsewhere), but some bitsof metal were unbent and rejoined with­in 40 minutes, in time for him to jointhe relight queue, which was led byWally Kahn.

The strong S.W. wind backed unex­pectedly far t::> beccme S.S..E., so pilotsdid not need to give first priority tocounteracting any tendency to drift to­wards the edge of the Control Zone,where a patrolling aeroplane was watch­ing for them "in case..·.

This was as well, because they neededall their .attention for keepi.flg airhornt:on this first leg. For example, GeorgeCollins, though he got 2 knots lift undera cumulus for a start. sank at 6 to 8knots in a downdraught on his way tothe next one, so failed to reach it. lanStrachan ran out of thermals in com­pany with Dick Schreder at Basinli:stoke.then, after returning for another try, didso again at Reading.. First to arrive at the goal was Andy

Gough, and, as it laler transpired, hemade it in the shortest time-2 hrS. 54mins. (12.11 to 15.05), giv.ing an averageof 80.4 kp.h. (49.96 m.p.h.}. He deservedhis success for his persistence in keepingon track; he always looked srraightahead for the next thermal sourCe in­stead of being tempted into deviations.

While Andy G(lUgh's maximum heightwas 3,500 ft., Humph,ry Dimock spentmost of his time between 1,000 and 1,500ft. and only twice rose above 3,000.Wally Kahn, on the olher hand, reached4 500 ft.. (immediately after .a sink ,to8(0) and only one pilot e~ceeded thiswith 5 '000' ft

Of i5 pilots who· rounded the turning­point, nine rea-ched the goal. But manydrifted too far teJ. leeward. and a few ofthese even fetched un by the coast atKing's Lynn, 24 miles W.N.W. of th~pal. Whether they could reach it fromthere against the wind depended onUpenetration". For instance, David Innesand Simon Redman, each with an SHK,managed to make Swanton Morleyagainst th~ wind, whereas of two Ka-6pilots who also reached King's Lynn.Peter Dawson had to land there andTony Deane-Drummond found 4,000 ft.insufficiem tCl gel him mQre than partof the way te the goal-if he had justreached the finish-line, he said. he wouldhave pulled ofi' speed amd re-<:rossed itgoing backwards in the correct direc'­tion, south to north.

a piece of marshland in Kent, whichPeter had coveted for a bird sanctuary.So he did a deal there and then. Beforethis, be had done one-and-a-half turnsof a spin for the first time in his life;his stall was not merely due to turbu­lence, he thought, but to the fact thathe was approaching a thermal throughair that was (in obedience to theory)rapidlyaccelcr'ating 'towards its centre,and so continually depriving him of air­speed. The severe turbulence not onlysent another oilot into an incipient spin,but made field landings extremely tricky;yet no-one suffered damage.

Br~nnig James had an adventure onthe way home; being stopped by anovertaking car after a qUick get-awayfrom traffic lights, he was told that histrailer doors were open and "something"had fallen out. In$pection of the trailerrevealed that tbe something was nothingless than the fuselage! Three-quarters ofa mile back they picked it up from thegutter-virtually undamaged.

but slowing up as he crossed each ther­mal. He was, in fact, lucky to havereached King's Lynn at a1l, because hehad forgotten to pull in his wheel allthe way to Thame; however, after that,where the situation demanded fast glidesbetween thermals, he realized his per­formance was not what it should be,thought a bit, and hit on the cause.Before that. Wally Kahn bad tried tote1l h-im albout the wheel but was on thewrong wave--length, whereupon anothercompetitor, who shall be nameless,joined in with "Don't tell him-let himland." David and Wally reached thegoal. but the other pilot didn't-perhapssome moral could be drawn.

The wind was not the onlv troublein making Swanton Morley awkward toreach; for several competitors it wasdifficult to find. Wally Kahn started hisfinal glide to the wrong aerodrom~,

realised it wheo he was down to 1,000Ct.. but managed to get back to 2,000 ft.and then made sure he had the rightplace by asking his fe1l0w competitorson the radio the right sort -of -questionsto which they could answer "affirma­tive". Another pilot found it by merechance. as he landed there withoutknowing where he was!

Nicholas Goodhart, unlike nearlyeveryone else, found no difficulty get­ting to ihame, but later drifted over theFeos, where thermals were "few and farbetween". and be found himself cross­ing the same canal several times CAndyGougb complained of seeing a canalthat wasn't on his map). Nick, throughcaution, started his final glide unneces­sarily high. but nevertheless made secondbest speed.

Gerry Burgess, with a Dart IS, wasthe only Standard Class pilot to reachthe goal. He had missed briefing be­cause. after hearing the B.B.C. forecast,he was convinced there would be notask. so went back to sleep.

Bernard Fitehett; the youngest pilot at20, and flying in Nationals for the firsttime. missed the goal by only a coupleof fields, to the disappointment of thosewatching at Swanton.

John Williamson made a good effortin landing 6 miles short in a machine, theHP-14, whicb be had hardly flownbefore.

When Peter SCOll landed, he found'tbe landowner to be the owner also of

The warm front which had movedover the country the day before was stillwith us at the 9.30 briefing. The depres­sion west of Northern Ire/and, withassociated fro Ills, was clear of the BrilishIsles.

The briefing marquee began to getrather wet.

Tuesday, 23rd ~ay

At 9.30 QJn. the depression was fillingand drifting slowly north-eastwards.

Theanswer was: "Photograph it:' Gliderswere t:> wait en the grid from 10.30 tillcloud base had risen to 2,000 ft. Then,c:\asperatingly, several times League 2were at the "go" stage when a largeshower would loem up. When the troughdid arriv~. there w~re two of it; then,instead of clearing the air, the secondone was followed by one cu-nim afteranother. each of which the met. manpresumed to be the last.

Finally, pilots becam~ so frustratedthat a ){)t of chit-chat went on over theradio. One announced gaily that he wasflying from Upavon and climbing in acu-nim at 1,000 ft. per min. and didn'tanybody from Lasham want their GoldC. height?! It took some pilots quite awhile before they were convinced thatthis was a practical jo'ke. Another pilotwas heard to demand to be served witha cup of tea in the cockpit. Othersmanaged forty winks therein.

Le3gue 1 had been to briefing after brief­ing during this time, and at one of thesethey had been set a race to Bicester andwould 13ke off immediately after League2 had been launched. Their task was,however, cancelled at 15.30 after someof th.e piJots had already taken mattersinto their own hands and de-rigged.

As for League 2, shortly after onepilot had said "Nobody can aCCuse the

task-setters of not trying", the task wascancelled; the time-16.10. Of course, nosooner was this done than the sun brokethrolLgh and qlLile a number of pilotshad local soaring flights. The latest13mled at about 19.30. feeling a lotbetter after his first opportunity to flyduring the meeting.

"Stop !r.e il you've heard this belore,b:1I tl;ere's a depression." At/er this in­troduction to tile 9.30 met. briefinK, wewere told tllat it had developed a "1V~ve"

Whatever the weather, the organiserswould have to try to pull somethin.t: outof the hat. If not both Leagues, at leastLeague 2 must be given a task. andwculd have to start as early as possible.

League 2's task was Free Distap.cewith pilot-selected start-first take-off at10.30. X=30 km.• Y=60 km. (remem­ber these figures). League I, to be briefedat 10.30. were to follow immediately afterLeague 2, also on Free: Distance. Afterfive d.ays of no .f1ying, crews had 1;<;­C:lme rat~er lazy abo'ut riggihg. but

now it was all hands on deck to beready and out on the grid in time. Therewas no time to send the "snifters" up.even to check cloud base.

Ken Wilkinson was first off at 10.35.follcwed by Ron Sandford and Chri,Wills at 10.42 and 10.48. This brightperied lasted about half an hour. and thefirst seven take-ofTs were still airborne.However. the next 20 launches or soalmost accompanied their lUgs b:lck toearth. and the landing area was strewnwith .t:liders.

Chris Wills, however, had contacted athermal soon after release and was wellaway into cloud. so he was able toreach better weather to the nonh. Hecarried on in good style till he reachedThe Wash. where he sank rather low.and at this point h:: had to decidewhether to turn north or south. Henearly chose south, but then thought tinta lot of others. who he mistakenlyima.t:ined to be dcing as well as he.would be rn3.k:ing for Norfolk. so hemight do belle I' by .~oing north. H;wingmade this choice. Chris then recognised.seen dimly through ra·in. a sea-breezefront, so he joined it and proceeded tofly up the Lincolnshire coast, sometimesat only 800 ft.. to a landing near Louth.267 km. from Lasham (166 miles). afterfive and a half hours in the air.

But those other imaginary pilots gotncwhere ne3r Norfolk. Only one othercompetitor. Chris Simpson. had m3nagedto get beyond the O~ford region. ALeI' alaunc:) at 11.28 he had many ups anddown; betwe(n extreme limits of 7.500 ft.mlx;mum and 700 ft. minimum. till.north of Thame. he was surpri~ed tocatch an 8-knct thermal which took himto a landing north of Huntingdcn.147.5 km.

Ron Willbie was down near Ab:ngdon(t:4 km.) and Ray Foot a/ Abingdon(59.5 km.). It only needed four pilots(IO per cent) past "Y~ to make th·is acontest day. Bu! however hard thescorers tried to stretch the map andshrink the rulers, no more than 59.5 km.could be measured for Ray. and so.after 6 days, league 2 was still withoutany contest. Nor, of cour~, d.id ChrisWills gain official recognition as the day'swinner, though, if he had been. only100 points would have been allottedhim.

Just before 15.00. League I werelaunched. but only 6 l'i1ots landed out.most of t.hem because they failed toscrape back to Lasham. There were 92contest launches for League 2. and 71for League 1.

League 2 pilots were thinking in terrosofgetting a good launch time, hoping thata good sh.are of luck would be withthem-to protect them f,r,om too manyshowers early on-hoping also that thetlirning"points would not be hidden bycloud or rain-no Airway problems, andthe thousand and one oth'er thinj!s thatcould happen on a day like this. Gettinground Thame would be a great help, asthe second leg had a good downwindcomponent. On the whole, their fearswere well founded, as many of themcame up against this son of situation.

Launching started at 11.23, and. withthe crosswind and turbulence to co'ntendwith, the first fow pilots told the Directorover the radio that towing was too fastin these gusty conditions. This was soonput right and tug pilots were briefed towatch their speed.

The five pilots who rounded Thamebefl'}re 13.00 did best, as a shower at

12.55 brought a number of others downin quick succession.

Although David Ince (Thame 12.45)sank tG 500 ft, over Aylesbury and againat Henlow, he' reached the fringes ofsome cumulus and, between Bassing­bourn and Cambridge climbed to7,000 ft. After that, however. he flewbetween only 3,000 and 3,500 ft. as faras Tibenham, trying to avoid the .cIagaround the turn-ing-point by keepingnorth: but it was no good and he soonlanded.

Four others who turned Thame im­mediately after the shower between 13.12and 13.45 also got either to Tibenhamor nearby. One of these, Peter Neilson.saw the shower at Thame and hadenough height to hang back there for awhile before turning ,at 13.45. Dan Smithhad the same idea but wa~ lower, so hedid not get away with it but drifteddownwind and Was unable to get back.

League I. with Anne Burns to takeoff first. inaugurated th: l!lunching at12.56. The skY was looking more promis­ing. and only four pilots landed backfOT al'lother launch while the tail endof this League were still on the ground.

Nat every pilot bothered to cross thestart line. as they were loath to leavetheir precious thermals. Nick Goodbarl,the day's eventual winner. went west oftr!lck where there were more sunnypatches. but he very nearly came unstucknear Greenham Commem. Onc.:: he re­covered from thal, however. he had aclimb t::l 12.000 ft. between Didcot andOxford. and on leaving this cloud ondead-reckoning climbed to 15,000 andthen 16,000 ft. He had aimed to be clearand west of the Airway on dearing thecloud, and he pin-pointed himself as 6miles south of Gaydon. Crossing tbe'Airway in VMC. he ran into a snowstorm over Leicester at. 4,000 ft. Despite~"is. he had no difficu.lty in reacbingRearsby. although the sky was bleak .anddevoid of any thermal activity. Nick hadtaken 2 hrs. 15 mins. for the trip.

John WiJliamson. who had entered thesame cloud about '500 oft. above Nick.was not too certain of his dead-reckon­ing and brok.e off his climb at 8,000 ft.Alas, this was not quite enough to get toRearsby, and he landed 26 km. short.Alf Warminger entered Nick's cloud10 minutes later. so only reached 8.000 ft.before its lift petered out.

Mike Garrod patiently worked someweak lift from 600 to 1,800 ft. nearSywell, but this was the last tit-bit hegot and brought him to within 29 km.of the goal.

He was one storm ahead of a gagglewhich had to land at Oakley. This onestorm was worth an extra 427 points.rewarding him with 4th place for theday. instead of equal 30th for the un-

Hugh Mettam and Bill Sheparcl flewstraight over Thame at 13.30 withoutlosing much height. Hugh later made aclimb to 10.000 ft. near' Camlbdge. andarrived with Bill at Tioenham at 15.30,where both landed.

Alan Purnell, who was saved by a lineof showers near Thame. s.layed In goodlift at the ed,ge of -this line. After turningThame he went N.W. so as to cross theA·irway at a higher level. From ·Crardiddto Bedford he had to use weak lift till itincreased to a good 6 knots, taking himto 6.000 ft.. and gaining another 2.000 ft.on his way out. Zig-zagging be:weenBedford and Newmarket. he used variousfront edge. of showers.' and at Tudden·ham was cljmb;ng again at :2 knot;. Hethen staried to hell' static ·i)1te~ference onhis radio and assumed this to be light­ning. Two turns later he saw an actualstrike go straight down t::l grcwnd about2 miles norlh, and a few moments later,another one to the south. Since (le p!ece'of doud under which he WB ci~c'ing

looked exactly like the one frem whic,l1tbe strikes came. he waited tensely forthe next one to strike him, but went onhis way and into his final glide.

Those who had landed out nea'rLasham were now on their second o~third attempts and seve~al could nowchange their zero scores into a fewpoints. There were 65 launches forLeague 2.

A depression (what, aRain?), with as­sociated low cloud and rain. was movin!!up Ihe C/rannel. and Ihe expeclOlion inl/re morninR w,as t/rat it would reach theThames estuary by eveninR. thus push·in!! the wind round from SE ~'ia E. NEand N to finish liP NW.

Ann Welch, hardly recognisable ingumboots, long plastic mackintosh andsou'wester, opened and closed the briefin~

in record time. promising another brief­ing for League 2 at 14.00, and League Icould at least go and find shelter fromthe eternal rain.

But at 13.00 a watery sun appearedand bits of clear sky as well, while adark mass of clouds to the east wasmoving away, not approaching. and thesurface wind was south, not north.

The depression had, in fact, changedcourse and its centre was moving north·ward to the Midlands.

League 2 brightened up like theweather and started rigging in caSe theyhad to go off in a hurry.

At the 14.00 briefing, weak to moder­ate ragged thermats in a 200'! I ~-20knot wind were promised. but cloud-basewould remain low. Anyone finding itbelow 2,000 ft. on their launch. Annsaid, must release without waiting to besignalled off. Pilot-selected launchescould start at r4.4~, and actually startedat 14.~ 1. Soon small gaggles were floating

around the sky, which in fact had aquite variable cloudbase between 1,600and 1,900 ft.

The task-Free Distance, X=25 km.,Y =50 km. Designated sta~t.

There was, however, some lift about,and as long as one could stay with itand take the risk of landing out a coupleof miles away, there was a chance. Thisctrance, when it came, was taken by 25pilots; some did so early on. and othersfrom their relights. The relights on thewhole did better by landing in the Ox­ford area, whereas the earlier startersdid not go so far.

Rika Ha~ood. who had an agonisingtime recovering from an embarrassinglylow height, was joined by David Ince alittle later, but the thermal petered outand they had to resort to "hillock"soaring near Streatley. The hillock couldhardly hold a Skylark and a Ka-6. soRika landed. For the next 30 minutesshe watched David scraping along thistiny hill, hardly more than 100 ft. overthe ground. If anyone deserved to get upagain and away, it was surely David,but he eveptuaUy joined Rika on theground.

The maximum points for the day, 190(6 pilots had passed Y), were shared by16 pilots. League 2 had at least hadanother contest day, though it took 88launches to do so.

Oh joy, we now had straw to coverthe duckboards, the sa.nd, and the saw''dust, so the muddy floor of the briefingmarQuee was decently buried at last.

Humphry Dimock, whom h<: ioinedat Abingdon, circling at 1,600 ft.. de­parted westwards from there, but Georgethought Oxford to the north would givebetter prospects. He soon found a work­able c1aud which took him to 6,000 ft.This S3.W him nicely rou;ld Bicester.where he met Wally Kahn, Who hadtaken off 12 mins. after him. Georgethen made a series of small climb3 ·incloud to 4,500 ft. This enahled him totraverse the Airway swiftly just belowits base. At Northampton he heardNick ever the radio, giving his positionas Bedford, weB to the east, but condi­tions north still looked more promisinJ!.and furthermore Leicester Airport (whoalso use 129.9 frequency) were givingthe wind as due south, 7 kts.

At Newark, with time getting on. oplvweak thermals between 1,000 and 1.200ft. could be made use of; so with a

The Corby steelworks C:lmeto his aid with a goed thermal to cloud­base (he did not do any cloud flying this'day) for the last time. At Grantham hecaught up with the high cover which hadpassed through earlier in ,the day, so hetl"ied to go more westerly where' thecover was less intense, The gaps ·betweenthe elol\d streets were, however. toolarge, so instead he used a very weakclotlo street stretching from Cranwellinto fle "murk". gliding abo'ut 30 milesfrom 2,600 ft. The pilots who had gonein a mo,e north-easterly direction allgot -caught by the high COver earlier on.

Rocky Stone, on his second attempt(take-off 17.15), had to land near Henley.On the approach he hit a tree and he waslucky to suffer only a broken ankle,cuts and bruises, but the glider wasbadly damaged. Until today he hadbeen lying in second place overall. butnow he was out of the running andlying in hospital.

However, the winners of all but thelast of the Daily Prizes were known, so­these were duly presented by our Vice­President. Air Chief Marshal Sir Theo­dore McEvoy. There were, of course.only three in each League so far­League I: Andy Gough, Nicholas Good­hart, George Bcurton; League 2: RalphJones, Ken Wilkinson. Colin Greaves. Inaddition, Chris Wills received a specialprize for his magnificent flight on the25th, which would have won him anofficial Daily Prize if only someone elsehad flown 500 yards further..

Prizes to the three meteorologists con­sisted of "a different kind of liquid",with more taste to i$ than the one theyhad so lavishly provided for us.

Leigh Hood (take-off 11.29) startedwell with a climb to 15,000 fe nearBasingstoke. He had intended to go toAndover first but changed his mind togo to Broadway (108.5 km.). Icing washeavy. but as the day wore on. he hadto go high to cross the gaps and dodgethe storms. He climbed to over Gold Cheight four times.

Ralph Jones (take-off 11.35), who wonthe day with 370 km. and landed at17.40 at Basingstoke, commented laterthat he was lucky in being able to turnnorth in an area of sky where otherpilots were falling down; thus,. in hisopinion, an element of luck was mvolvedin a Cat's Cradle (but was It luck?).

Charles Dorman (take-off 12.26), whohad gone. to Bicester, then to ~road~ayTower. could not find the turnmg-pomt,so he back-tracked a little and made forKeynsham instead. This was almost intowind, but he managed to contact -theedge of a large line of showers and flewstraight and level for 15 miles or so, asfar as Nympsfield. From there he hadno trouble to get to Keynsham, thenback again downwind-this time to landnear Cheltenham. The potato field causedlittle damage, but it ~ook him sometime to get the mud out of the nose­pitot!

It is interesting to note that 7 of thefirst 10 places for the day had beenlaunched before 12.00 and were firstlaunches. There Were 78 launches forLeague 2.

Later, Tony, a Major-General. com­mented to Paddy, an Air Commodore,that he th0ught it was carrying lnter·Service rivalry too far.

George Burton, who had climbed to9,000 ft. over Blenheim Palac;e. withPeter Scott followin.g him in the cloud500 ft. below, decided then to keepnorth of the eu-nims. Then fr(lm Fair­ford he could see wet runways at SouthMarston. On hearing that David Carrow.Wally Kahn and others were going towait north of South Marston to let thestorm go through, George decided togo through the storm and get cn. withit. He turned South Marston at 2,500 f,t­just after tne storm. and pressed on forhigher ground near Lamboum. Nowdown to 700 ft., he was confident offinding lift as the condttions lookednormal again. He was soon at 4,000 ft.and had no more trouble '10 Lasham.Peter &011 hit one of the storms andhad heavy icing, which, with heavy rain,brought him quickly down.

John Williamson gained 35 minuteson George Burton by climbing, to 14,000ft. on the second leg. and so could turnSouth Marston before the storm.

Nick Goodhart had seen a lot ,of light­ning around Brize Norton after comingOllt of a cloud at 12,000 ft. He lostheight to 5,500 ft. at Fairford. He turnedSouth Marston, got low over Membury.and from there had a difficult time toLasham. With 6 miles to go he hit sinkand was down to 600 it. al 4 miles oJ,l1.Then he oit rising air. and without circ­ling, flying at 55 knots, got back to800 ft. with 2} miles to go--enough tosee him across the finish li,ne.

Anne Burns also had plentY oftroubles on this trip. Water in the I'itothad frozen, her instruments failed. andlightning stfllu;k through her foot. Rathershaken, she pressed on. found the finalleg hard work with no obvious thermalSour1:e to go for. 'but made Lasham<>fter all.

D·.URING. a recent visit. to West GeT­many 1l proved possible to call m

on Martin Schempp at Kircheim-Teckand spend balf a day going round hisfactory and ma'king a detailed examina­tion of the Cirrus.

The second prototype. which has aconventional tail, was almost completeand has since flown. On 8th J,une theCirrus, order book ran to 34 aircraft and,incidentally, 58 SHK's have been sold.Cirrus production, just starting, is ex­pected to rise la three aircraft per monthby 1968. It will be flown by Rolf Kunzfor Germany in next year's WorldChampionships and in addition it willprobably be flown by Swiss, Italian,American ,and Canadian pilots. SignorOrsi, of Varese, Italy, is buying the firsttwo prototypes..

The Cirrus made its eom~titjon de,butat this year's principal contest in Ger­many from 29th April-7th May. It wasflown by its designer, Klaus Holighau5.That the contest was won by RudiLindner flying a special 17-metre Phoe­bus. and that Holighaus, with relativelylittle experience on the Cirrus. cameequal 2nd. is perhal's some measure of itsfuture potential. On the 14th June Holig­haus failed to complete the 500-km. trioan.gle. by 10 km.-at.l:44 it hardly bearsthmkmg about. Which leads one on tothe design philosophy-the thick wingoffers high aspect ratio combined withlow structural weight. which in t'urnresults in excellent climbjng perfor­mance. Indeed, HoIigbaus claims that hefound it so good that he flew through­out the contest with 100-140 Ibs. ofwater ballast, which he did not find

292

necessary to jettison even late in the day.On a theoretical basis the cross­

country cruising speed of the Cirrus isshown to be bette.r than the BS-l forachieved rates of climb of up to 3 m.lsc;c.In practice it seems about equal to theBS-I on the glide at about 140 km./h.­better below this speed and worse above.Finarty there is the point that, with noflaps to adjust, it is impossible for thepilot to throwaway performance as aresult of continual small errors in speed Iflap relationship. Measured rate of rollthrough 90° at 1.4 Vs appears to bebetween 4 to 4J,- s.e.conds.

The Cirws is the third 'German plas­tic sailplane to 'go into quantity prOduc­lion, the first two being the Phoebus(manufactured by Bolkow) and theLibelle (manufactured by Glasflugel)-­although. Schempp-Hirth built the 'firsttwo Libetle prototypes. Cirrus, however.is unique in using a rigid foam plasticas a sandwich filler between inner andouter layers of glass-fibre instead of themore usual balsa plank construction,whicb is also used on the AS-12 andmany of the Akaflieg specials.

In point of fact, the first prototypewas built using balsa because this wastne only reasonable way to produce afirst-off and to achieve a master for themanufacturing of production tooling.

Ghss-fibre moulds are subsequentlyproduced by "casting" them on to proto­type wings and fuselage. MaTtinSchempp admits that tooling (;ost is highcompared with wooden aircraft manu­facture;. but he is aiming to break evenwith 100 Cirrus, and for quantities inexcess of this figure he believes that

Page 27: Sailplane & Gliding 1967

plastic' sailplanes are highly competitive.He is sati1ified that ten years of Germanexperien.ce with plastic structur,es hasdemonstrated their integrity and fati,guelife-he believes that some early failureswere due to lack of understanding andadequate quality con.trol, particularly inthe curing process-in short, that the dayof plastic structures has arrived. In termsof static strength the Cirrus wing hasbeen loaded to the equivalent of nearly15 g. without any plastic failure, and itis claimed that there is no loss of mech­anical properties up to 60·C.

The aircraft itself is perhaps not quitesO elegant as the SHK-although this islargely a matter of opinion, but the firstthing that really strikes one is thesensible, comfortable and roomy cock·pit and the excellent all-round yiew. Itwas interesting to discover that theCirrus canopies are made in Switzerland,as a're those of the AS-12; and that theoptical qualities are equally outstanding.

Internally, many SHK features suchas in-flight rudder pedal adjustment. air­brake. j)arachute and undercarriage re­traction controls were in evidence. By acunning roller-blind arrangement it ispo~ible to adjust the tension cf thecanvas seat-back in addition to varyingits angle. One gained the impression,however, that with a reasonable ,thick­ness of seat cushion headroom might besomewhat limited. In view of the other­wise gCflerolls amoullt of space in thecockpit. this would b: a pitv. Otherfeatures in,e1ude: a nose air intake forcockpit ventilation which. surprisingly,incorporated an open forward-facingpitot tube and static vents On each sideof the cockpit close to the instrl,lmentpanel. Immediately to the rellr of thecockpit is a welded steel tube structurewhich carries the single retractablewheel and the wing mounting pick·uppoint.

Rigging is undoubtedly better than theSHK-although the manufacturers claimthat this can be done easily with onlythree people, ~t may he open to doubt.However. there is only one loose com­p~nent involved in rigging the wholealrcraft~th"e main wing pin.!

The tailplane attachment is particu­larly neat; it slides into a slot in the fin,engaging three spigots in the process,and w:,en 'fully home locks automati-

cally: in position. Locking is indicated bymeans of a short external wire rodmoving in a slot. This lock is also themeans of unlocking the tailplane whende - rigging. Elevator connections areautomatic.

The tailplilne is thin and features asm~1I elevator of only 30% chord, simi­lar to that first seen on the D-36.According to calculations 20% chordwo.uld have been adequate_

The fin and rudder have a thick pro·file, particularly towards the base. Thishas allowed the landing parachute (notused above five metres) to be housed inthe bottom of the rudder. The latter ishinged on its starboard side.

One modification still to be incorpor­ated in tl:le second prototype is a largetailwheel some eight inches in diameterwhich will be sunk into the bottom ofthe fuselage.

The wing structure is simp,Ie in theextreme. Sandwich top and bottomskins, a massive all-glass-fibre main sparand a single glass-fibre rear spar-thereare no ribs. Glass-fibre tubes in the D·nuse in e.aeh wingroot can carry waterballast totalling approximately 70 kg.Considerable effort has been made toreduce lower to upper surface leakagevia the airbrakes: these have been segre­gated fore-and-aft into enlirely separatec.ompartments for the upper and lowerDFS paddles respectively. In addition,each of the paddle, is fitted with a fairlysophisticated spring-loaded seal. Aileronsare upper-surface hinged without anyform of aerodynamic balance.

And 50 finally one comes to the price,which is Quoted as 29,400 OM for 1968d~livery, including tail parachute but lessinstruments-a somewhat daunting sum,but then this is a formidable aircraft.

One further thought for prospectivecustomers~water ballast 100-140 Tbs., asteel tube structure in the centre of thefuselage with stowage space above, alldthere is a proven two-cylinder four­stroke engine already, availa:ble, whichMarlin Schempp is activeJy consideringfor the next stage of Ci~rus development.

Max. LID of I: 44, minimum sinkaround 1.7 ft./sec.. and a retractablepower plant. for self-launching and re­trieving seems to suggest the prospect ofa Dew dimension to our soort. but this isanother whole subject" in itself.

THE FREEDOM OF THEHILLS

H E switched on his sealed barograph,strapped on his knee-pad with its

stop-watch, and squeezed himself intothe cockpit, threading his legs ar<)tIndthe oxygen cylinder ~nd wedging himselfinto the gap between a bulging mappocket and the radio. In the pocket wasa calculator, regulation maps, a pad oflanding certificates, an air-law booklet,and evidently a good deal more besides.From the floor he retrieved his specialsealed cameTa fOT photographing turn­ing points, strapped himself in, andstarted his cockpit check. Two of thethree variometers weTe working-evi­dently a satisfactory proportion-andeverything else seemed in order. Hetouched the undercarriage and flaplevers as if to say "this time there'sgoing to be no confusion". Then hetested his radio and finally closed thecanopy firmly.

Everything was ready--or was it? Hewent through the paper-work in hishead: maps and insurance inspected bythe contest organisers, and indemnitysigned-yes; certificate of airworthiness-yes; private owner group membershipand competition number tax paid-yes;gliding certificate and competitor'slicence-in his wallet; radio licence,barograph calibration chaTt, compasscard, parachute log card-yes; daily in­spection book: completed and signed­yes; goal declaration form completed

294

and landing certificate ready - yes;launching ticket-now what had he donewith that? He opened the canopy andundid the straps....

A little later he was launched on aflight wh ose purpose was to arrive at thegoal having had as little flying as pos­sible, thereby ensuring him the maxi­mum number of marks (worked outaccording to a rather complex formula),which would in turn ensure him a goodrating (worked out according to a verycl?mplex formula), which should get hima place in a competition whose chiefpurpose..... The otheT day I bought a bunjey-or,to be more correct, half a bunjey. It waseither half a barograph or half a bunjey,and I settled for the bunjey. A singlestrand of brand-new bunjey, ringed ateach end, with all the promise of theday's first cumulus. A bunjey that wouldlead us to places that have never beensoared before, views that have neverbeen seen, challenges that have neverbeen met. A bunjey that symbolises thefriendship that s~ms from competing to­gether against the elements rather thanseparately against each other.

Laurie Vandome' brou~llt it in from hisLand-Rover and laid it on the floor. Thefloor, I s.hould mention, of my house inAberdeen, situated barely a dozen milesfrom the nearest 1,000-ft. contour. Welooked at it, and marvelled that such a

Page 29: Sailplane & Gliding 1967

diminutive coil could hold enoughenergy for our needs. We put a map onthe Boor beside it, and surveyed the hills-Bennachie and Tap 0' Noth, Suie andthe Hill of Fare, Cairn William andCorrennie Moor-and over all we €ouldpractically see the long white lenticu­lars that so often dominate the Aber­deen air.

The day after Laurie and Peter lameshad arrived we raised the Olympia 463'strailer into its mountain-climbing posi­tion by inserting three-inch blocks abovethe axle for extra ground clearance. Ibuilt this 5-ewt. trailer with mountaintracks in mind, keeping it as light aspossible, and making the last four feetof floor rock-proof from below. Thispaid off when it was suspended by itsends across a burn. the water gurglingbeneath its wheels. But its lightness wasa worry in strong winds, for unladen itbounced clean into the air at everycorrugation in the track. So if one dayyou find a trailer full of rocks comingdown a mountain, don'llaugh.

The following day dawned bright andclear, with a thirty-knot south-westerlyforecast. We decided on a tour of in­spe~tion of the possible launching sites.but took the Olympia along just incase.... First we went to Tap 0' Noth.a whale-back of a mountain with a goodsheer S.E. face (800 ft. by 2 miles)and a small N.W. slope, of which moreanon. The S.W. point of the hill risesconical! y to a vitrified fon at 1,.851 ft.,an~ half-way up .1 had found a bunjey­pomt on an earher survev. But beforewe reached this spot we had to cross asloping field up which the wind wasblowing with such enthusiasm that therewas only one thing to do-rig. Laurielaid out the bunjey with loving care.a.nd in no time it was being stretchedtight by the Land-Rover before my veryeyes.

Alas! I suddenly realised tba t we hadnot chocked the wheel, but just at thatmoment Peter released the tail, and witha single bound the Olympia was air­borne. I pulled back to gain height.levelled out, released, and turned to­wards the Tap 650 ft. above me. In oneshort sweet traverse of this conical out­crop I was at the top, to the surpriseof a Forestl"y Commission fire-watcher.A few more beats and I was at 3000ft. in the lift of a hill which the stre~m-

lines should de1initely go round, notover. Along came a scudding Scottishcumulus, and I tucked myself into itsthermal. March, in the North of Scot­land, and a steady .8 knots up untilcloudbase at 6,000 ft. I know it soundssil1y, but there it was.

I pulled out my map. Not one ma-rkedwith airways, mmd you, because thereare none within a hundred miles. Theydo say there is a Purple one occasion­ally, but it merges imperceptibly intothe heather of the hills. To the North Icould see Caithness, seventy milesaway, and would have seen more hadthere been any.

The next day brought a brisk sun·bearing north-westerly, and we hurrieddown to Glenesk to try .another of myreconnoitred sites. But alas, the glidersnever saw it, for the access was fromthe south-east, involving a thoosand­foot climb to the crest of the hill. andthe snow 'deieated us. An .alternativetrack looked promising until it metLaurie's Burn (its Ordinance Surveyname!), and the more Laurie's face litup at the chaIlenge, the more the trailer­owners' faces sagged. When Lauric

There was not a hint of a lenticularanywhere. I sat up there in the sun,taking colour slides with a non-regula­tion camera, and pondering the chancesthat I was the only aircraft over t.hetwenty thousand square miles spread outbeneath me. When, to bring to a closea very pleasant tlig,ht. I landed in a field,I happened to walk ,back along thelanding run: there lay the ten-footlength of holding-back rope. Peter reallyhad let go!

That was the day, so it is said, thatthey had to put the gliders away at Port­mcak because of the wind.

When we returned to Aberdeen wefound that John and Pat Griffiths hadanived with a Skylark 4 in tow, corn.pleting the party. So on the morrow w.~

hurried up to Tal' 0' Noth, to find avery g~ntle breeze blowing up the field.which began to die even as we riggedthe Skylark. For launching the"bomber" in these conditions we addedan old bunjey beside the new one.making three strands in all. and chockedthe wheel very' carefully. John had dis­covered some old clothes line that hadrotted sufficiently to break when thecheck-rope came taut, but apparently notbefore.

The more we talked, the less the windblew. but soon each of us was (errone­ously) under the impression that theothers thought John shOUld be launched.a'ld John himself was strangely silenLSo was the wind.

started talking about sever-al days' .civilengineering, and StuaJt WaIler, the restof us adjourned for lunch. A marveIlou5day on. but not over, the hills.

So when the foIlowing day deliveredup ,a lig~'1l north-westerly, with lowcloud and snow showers, we headedback to Tap 0' Nolh to try to launchoff the heather round the corner fromthe first site. It happened that the Olym­pia. by now christened "Cockleshell",was first up the track, but when thebomber tried to follow, the trailer stuckin the mud, being that much heavier.Then Laurie's Land-Rover itself stuck.and by the time Laurie had extricatedit by a pro.cess involving an infinitearray of tiny pulleys and much enjoy­ment, it was clear that if wo: got theCockleshell alone airborne we would befu~~ .

One advantage of the delay was thatat least it gave the Tal' time to come outof clOUd. and rather la'te in the after­noon I was catapulted off to try theN.W. slopc-a mile long but only 250ft. high (except just where the fort is),

with a larch forest at its foot. and be­yond that an emergency landing field.On the far side of the field the grounddrops steeply into a narrow glen. I hadno intention of following it. It turnedout that the wind had just enoughstrength to keep me at the level of theridge, though well below the fort Itself.So for half an hour I plied up and down,level with the launch point, unable toclimb the conical hill. Sometimes I couldsee over the whaleback on to the splen­did S.E. slope-what a clutching handit must have been offering!

During this time I had been watchinga snowing c10udmass approach, and itsoon became obvious that I would haveto abandon my beat. Not knowingwhether the glen in front contained anyfields. I was hesitant to try an offeredline of escape on to the hill that guacdedits entrance, but the al,ternative was toland. so in the end I took the plunge.The hill worked. the glen would nothave done. But the cloud now stretcheda snowy finger out even to this haven,and I looked for a further escape route.

t need not have worried, for just be­fore the opaque curtain of snow arrived,the Cockleshell was lifted up towardsthe cloud. I went with the lift, passedover the first hill, and was soon carriedout over the blessedly-large fields ,to thesouth-east of Tap 0 Noth. The cloudcarried me at 3,000 ft. under its advan­cin~ edge (Turn & Slip still on holiday),until I was within reach of Bennachie,a splendid mass of isolated hill fourmiles long, with 1,000 ft. north andsouth faces. I flew to i~ welcomingslope. but could not relax for long­the snow was catching up with me, andsoon I had to flee to Cairn William, fourmiles further on. There I had the mor­tifying experience of seeing the east endof Bennachie-oow out of reach-stayclear of the hanging cloud, whilst thedarkest mass headed straight for me.The game was up_ I tried to hitchanother lift, but the cloud was tired,and I fled round the end of CairnWilIiam to a field near Monymusk,seventeen miles from Tap 0' Noth. Thedistance is no matter; the intense enjoy­ment of this type of flying derives fromthe unique and lonely harmony. of sail-

By now it will be wondered whetherinviting John to Aberdeen was merelya ruse for getting more people to helplaunch the Cockleshell, and the next twodays only helped to confirm this sus­picion. For on the first of them thewind blew from nowhere in particular,and we had to be content with findinga new site for a north wind, two mileswest of Bennachie, and a mud-freeapproach to Tap 0' Noth. Both theseexplorations paid dividends. On thesecond day a passable northerly broughtsunshine and scattered snow showers,but John was mildly indisposed, so withheavy heart (or stomach, as the casemight be) we went out with Cockleshellalone. The new site west of Bennachieproved a dream, even though it wasonly at 999 ft .. atop a two-hundred-footslope. It finally brought home to methat on this sort of expedition one mustlook for launching fields near thebottom of large hills. Let the wind dothe work.

A couple of beats over the launchpoint, and I tiptoed across to Bennachie.This mas"Sive hill is not very steep, andit was delightful to arrive half-way downand saunter across its heather-smoothslope. In time I was high enough to pullout my sandwiches and my camera.Another sparkling day revealed hill uponhill to the south and west, and fieldupon forest to Aberdeen and the sea,each hedge and banJc. and road beingetched in a dusting of snow.

Alas, the tele­vision engineers beat me to it, for thehill is topped by a monstrous piece ofironmongery.

•••Why did we bother to put in so much

effort for a mere lit hours' flying?What is it that makes us dream of thehills even as we flash across a com­petition finishing line? It is many things,but principally it is the freed()m. It isthe freedom of complete independenceand self-reliance. To explore, to experi­ment. to pioneer, to enjQy the hillswhether over them or on them (or, onvery muddy days, in them). To share inthe satisfaction of operating indepen­dently with methods now so rare thatthey have not been scrutinised, dissected.codified and ossified by committees.

With a score of six-and-a-half hours'flying to the host, and two minutes tothe guest, with one day left for play,we needed some exceptional conditions.In the event we could not complain, forthe fickle wind backed to the south-west,and blew strongly enough to makeground-handling difficult. John went offfirst bounce from the field at Tap 0'

Noth, and was soon beating along alocal wave between six and seven thou­sand feet. Unfortunately it was rathera grey day, so he missed seeing the coun­try at its best. Lenticulars, though nottext-book ones. were scattered aroundthe sky, but the air was rough and hos­tile. I was launched an hour later withsuch acceleration that I released tbebunjey under tension. leaving Laurie andPeter a fine tangle. As I explained later,I was only trying to coil it up after thecamp's last launch.... However, 1could do no better than John; perhapswe were at the bottom of something big.But at least John had three hours' fly­ing. and we landed together in a verystrong wiod just before the rain came.

This ruling relates only to the integrityof the primary structure, and the BGATechnical CQmmittee reserves' the rightto investigate other engineering featuresand the flying characteristics.

The Kodak 'Instamatic' 25 camera has been specified by the BritishGliding Association as the camera to be used in competition gliding.

This is why..

It's easily loaded. The film is in a cartridge which simply 'drops-in' to thecamera. It only 'drops-in' one way, so you can't misload. There's no filmthreading-no fumbling. It has a double-exposure prevention device, soyou can't take 'two-an-one'. You have a choice of either black-and-whiteprints, colour prints or colour slides. The l{lrge, eye-level viewfinder lets'you compose your picture easily, instantly. Ifs light compact and easilystowed away when not in use; a pocket will do.

HP-14 EXPERIMENTALBy JOHN WILLlAMSON

THE HP-14 made its flying debut inthis country only a fortnight before

the Nationals. Briefly test-flown by theBGA No. I Test Group and then byDerek Piggott at Biggin Hill, it washanded over to me on 11 th May. Theweather at Bicester was appalling. Wepressed on with the fettling and dealtwith minor snags as they cropped up. Atlast. three days before the Nationals, theweather c!eared up enough for us to fly.

Interest in the new "tin-ship" centredaround the use of tbe flaps which ex­tended over 70'1, of the 9pan. The con­cept is simple and attractive. The flapshave a tr~ple role. In addition to slowingdown the basically fast wing section forcircling in small thermals, they alsoprovide approach control and they limitthe speed to Vne in an emergency. Todo this they are designed to operatebetween 10° up and 90· down.

When I took her over. however. theprototype, No. 515, was fitted with adirect-drive flap lever which gave flapmovement down to only 60°. A 5-ft.diameter tail-parachute was fitted forapproach and speed limiting, since 60°flap is virtually useless for these func­tions. After ten rather damp circuits Iwas happy with the parachute approachtechnique. The 'chute deployed equallywell at any speed between 38 and 80knots. The deceleration was smooth butfirm. and the nose had to be put downat about 30° to keep the' speed safe. Re­packing was simple and the device be­haved impeccably.

Next day it became soara'ble, and inspanking conditions which suited herwell, "515" won the 98-miJe race toWorcester and back. Friday was dud andwe arrived at Lasham with II flights and7 hours on type. Dick Schreder arrivedat Lasham early on Saturclay with thesecond prototype, No. 514, which hadb~en completed the night before. He in­vIted rne to test the effectiveness of 90°flap for approach control. 1 was so im­pressed that I agreed to have "515" modi­fied overnight in time 'for a possible tasknext mOrning. III this way I could doaway with the parachute and some corn·

pensating ballast in the nose to lightenthe sbip by 30 Ibs.

The new system was a raek-and-pin,ionrequiring 4~ turns over the full range offlap movement. Approach with full flapis impressive. A 45" dive is needed tokeep the speed up to 50 knots. Thetecbnique is to keep the nose aimed atthe desired round-out point and thencontrol the speed with the flaps. If over­shooting., lower the nose and wind downmore flap to prevent build-up of speed.If undershooting, wind up flap a littleand raise the nose to improve the glideratio. Above all, the speed must not beallowed to drop too far in an attempt tQ,stretch the glide with a lot of flap, o~.

On belatedly raising the fiap, the glidersinks rapidly and there is no escape fromthe undershoot. At the speeds used (45­55 knots) on a normal approach. theflaps are light and easy to use.· Theapproach really steepens at about 70° offlap" so that although it takes three turnsto get that far, thereafter all approachadjustments are made with the last turnof the handle. On rounding out with fullflap, the HP-14 will float on and c,p.ground effect keeping bel' airborne rightdown to 25 knots. Quickly raising theflaps a couple of turns after round-outcauses her to sit firmly so that the wheelbrake may be used. With a littIe practicethe ship can be brought down a lotshorter than the SHK or even the Dart,to touch down at a mvch lower ground­speed-a good point in rough fields.

There is always some speculationabou~ the behaviour of a V-tail glider ina crosswind. "515" gave no trGuble at allan{) I feel sure the steerable tail wheelwill alsQ help in this respect. The earlierparachute mo{)ification had resulteq in afixed wheel for me. It was noticeable ontwo days when the wind was directlyacross the Lasham runway that the twoHP-1.4's kept straighter than most ontake-off. In this context I owe it to theaircraft to explain the severe ground loopI experienced on the first contest day. Inall the rush to get the flap mod. done,that well- known aviation engineer,Murphy, helped with the .igging, Thepre-flight cockpit check did not revealthat one ,of t'he automatic ruddervatorconnections hadn't. The control surfacecould be pushed upwards and it thenmoved back to neutral under gravity. Thestick/rudder mixing system is such thatif one ruddervator is disconnected allcontrol movement, under flying loads.can be fed to the free rod. and no con­tml surfa,ce movement results. I attribu·ted the initial swing to the wing tit!holder, but when airborne and stillswinging to tne right I released. "515"ground·looped across an intersecting run­way, leaving a 2o-yard skid mark on thetarmac. I am convinced that most gliderswould have been wrecked. As it was. theprotective wing-tip plate was torn offand the aileron mass balance damaged,the tail wheel was wrenched askewand jammed, and the spun aluminiumnose cone was flattened on the under­side. Within the hour the wini tip was

306

pop-riveted back on, the tail wheelstraightened and the nose cone ignored,and we joined the last row of the launchgrid for the race to Swan ton Morley.

As is common with prot()types. "515"was heavier than expected.. This waspartly due to the stringent ballastarrangements required because so littletest-flying had been possible. At a wingloading of more than 6 lbs. per sq .. ft..I was at some disadvantage in weakthermals against some of the others. Thefl'aps up, slraight-an<!.level stall speedwas 41 knots IAS (position error notknown), and at 45· of bank she couldnot be circled comfortably at less than50 knots; 15· of flaj) pulled this downto an acceptable 45 knots. More flap putthe sink up and was usually not worthwhile. In turbulent conditions. however,I found it useful, when suddenly losingairspeed, to ease out another 10· ()f soto hold off the stall until the next gustedge arrived. .

With the flaps UP between thermals,the HP·!4 felt right at 70-80 I\nots. thefuselage lying almost level at thesespeeds. Optimum cruise speed for 5­'knot thermals is 90 knots. and at thisspeed the "51 Y' ran away from eveTythingexcept the most persistent SHK_ Whencleaned up in production, I feel sure theconsequent reduction in drag will resultin an aircraft well ahead of anything wehave seen in this country so far.

I took advantage of one high tow totest the effectiveness of the flaps as sPeedlimiters. At 1J0 knots. initial applica'tionof flap caused a nose-up trim; and as

Page 41: Sailplane & Gliding 1967

the air loads decreased, full applicationcould be made at 90 knots.

Diving as steeply as I dared (l hadforgotten that loose articles would tumblearound my feet I) the s~d did not goabove 65 knots. I was confident that Icould thus cope with any inadvertentattitude in cloud. In the event I foundcloud-flying straightforward. althoughwith no trimmer there -was not the com­fortable "on-rails" feeling of previousSlingsby gliders.

My final incident with "515" came upthe Friday of the "Possibles" Contest,

2nd June. The first turning point of our500-km. triangle was obscured by l'Owstratus. I turned back to the nearestbreaks, five miles away, and descendedbelow cloud tops through a hole justlarge enough to contain a SO-knots circleThe hole revealed only a town and ara.i,lway station. Cloudbase was 300 ft.above ground level and the fields werenot large. The wind, forecast to be 10knots westerly. was, in fact. 5 knotseasterly, but I couldn't see that.

OSTIV AT STUTTGART, 4th-5th MAY, 1967By FRANK IRVING

THE Osnv Sailplane Development. Panel is a group of people concerned

with glider design and/or airworthinessin their various countries. They meetfrom time to time under the benevolentand efficient chairmanship of Lt.-GeneralC. W. A. Oyens (Netherlands) and fromtheir deliberations emerge such works asthe OSTIV Design Requirements for Sail­planes, which is rapidly becoming agenuine international standard. The pro­jected "Sailplane Designers' Handbook"was perhaps a little too ambitious. andis currently in a state of suspendedanimation. Other activities of the Paneltend to be more controversy-provoking:the mention of a mini-standard-class(now. dropped) produced wild enthusi­asm m some quartets and a lot of no­enthu~iasm elseWhere; and proposals forchangmg the standard-class rules areregularly put to C.V.S,M. and equallyre.gularly rejected. It is certainly astI.m.ulating committee. as befits one con­tamlOg four or five celebrated designerst~gether with airworthiness representa­tI'fes from all the major gliding coun­tnes.

:JOe. Stuttgart meeting in May wasPflman.ly educational, being devoted todlSplaymg the current German state-of­the'art in the manuhcture and testing ofglass-fibre gliders. We had a paper fromDr. Epplcr on manufacturing methods,another from Herr SChatt on airworthi-

Like any other material, glass-fibreresin has both advantages and dis­advantages. It is mainly celebrated forthe accuracy of contour which can beachieved together with such a superbsurface finish that the final product isof wind-tunnel-model quality. And. al­though all the manufacturing processesinvolve skilled hand labour, the numberof components is small and there seemsto be an overall saving in man-hourscompared with wooden construction.Against this, whilst the material isstrong, its density is fairly high and itsstiffness is low.

. Herr Schatfs paper was prepared forthe Working GrouD for Flight Safety ofD.V.L. (German equivalent of A.R.B.).It reviewed materials and their proper­ties, m~thods of construcJion, testing(static and dynamic}, flutter, and detailsof production and primary inspection ofmanufactured gliders. It was an impres­sive paper which indicated th<tt despiteconsiderable gaps in the knowledge ofmaterial properties, and known disad­vantages of the materials, D.V.L. arehonestly doing the best job possible atthe present state of the art to ensureairworthiness.

For example, the standard loading testfor a prototype wing is:

(i) Static test up to the "limit load"(i.e. proof load)..

(ii) Fatigue test, This is based on adesired life of 15 years at 200hours and 200 launc'hes per year.(\. scatter factor of 3 is assumed.so the actual test s.imulates 9,000

(v) Ultimate load test with the criticalloading at 54'C.

The distinction between (iv) and (v)is not very clear in the written report.I think (iv) refers to design ultimate,wher,eas in (v) they act.ually break it.

SELF-TAUGHTBy N. E. JOHNSON

After one of Dr. Brennig lames's out­landings during the Nationals, he wassurprisingly greeted by a man who hadlauRht himself 10 fly on cheap, secondc

hand gliders. yet had made no contactwith the r.:liding world apart from read­ing this magazine. Here is his story.

I HAVE always been interested in any­thing that flies. and having a brother

that likes it too helps a lot-but youcould never get -him off the ground.

I had my first glider, a Tutor. abouttwo years ago, March, 1965,; it 'was ad­vertised in your SAILPLANE & GbIDING.Devon and Somerset Gliding Club hadit for £50, I had to knock a trailer to­gether to fetch it that Sunda,y. We didov,er 400 miles but ,it was worth it. Thewings were 1,lncovered, so I had to buyfabric and re"cover them, :but it gave mea chance to see how they were put to­gether.

I went on to an ,airfield where peoplewent to learn to drive, but I think theyenjoyed it as much as I.

The first day I never got off the run­way; I just tried to keep the glider goingin a straight line. I ended up in corn onthe side of the runway, and how manytimes I ended up in the bushes Icol1ldnot try to remember.

The next Sunday ,We went, I told mybrother-he was driving the tow-car-togo a bit faster. We started off and thenext thing I knew I was up in the airand I don't mind admitting it-I reallyheld on to the side of the glider. andwhere it went I let it go. in the bushesand corn; but I soon got the hang ofit, and was soon flying high enough toturn and come back.

I flew that glider for months until­the last flight of the day-I hit a pile ofconcrete. It was nearly dark, and itsmashed into pieces. I got out with onlya bump on the head. I thought that daywas the saddest of my life; I had noinstruments, so- I d.id not know ever whatspeed I was do-ing. So I Pllt it down tothat, and looked for a second glider.

I think that was advertised in one of310

your magazines also. I went to OldSarurn, near Salisbury, for that one, butin the m~antime I had built a new trailer,so I had no trou'ble there. This was alsoa Tu!\!)r, so I had a few spares. This oneI stripped down and checked it through,I was getting good at that now, havingr,epa4red the first one so much.

The runway I had been using had sjncebeen taken uP. so I had to find same­where else and, as you know, it can bevery hard.

I have been threatened with everythingyou could think of, but in the end Ifound a fllrmer who let me go on an air­field as long as I kept out of his corn;when learning to glide by oneself thatcan be' a job also. This 'drome was illsobeing taken up. I fl.ew from there manyweeks until-the second flight of the day-the IQW rope broke. I was about 200feet up, and, just going UP. could notturn round and land or carry on as therewere diggers and lorries up there. So' Iflew out over the crops, but went a bittoo far and tried to stretch the glide. andstalled it in the tOm, doing more damagethan if I had landed in there. It smashedthe glider to pieces. Another sad ·day­not having any instruments again.

The glider I have now is a KirbyCadet. I have no a,irfield yet but go in afield which is not very big so I 'have apulley tied to one tree in the corner withthe tow-car facing the glider on take-off.But this is not very successful. Once Iwas trapped in the cockpit by barbedwire with bleeding fingers and half thehedge down. But my glider was OK soI did not mind. It was tow rope troubleagain and instruments, Dot knowiniheight and speed. But we d\!) 'very well. Ithink:, considering I ·onlypay about £50a glider. and most of the repa.irs we doare patching, and I must mention brokenseats, I am very good at knocking thebottom out of them, I have bad so manythings happen, I just can't think of them.

I think gliding is just a;bout the bestsport there is, even in my little way, butmore so I think because I taught myselfand scared myself many times. But aslong as- I get scared, I know I am safe,and know I am not getting too confidentand careless.

I have also got seven cbildren-fiveboys, and they are just as k.een on glidingas r am, and they help me a lot.

CU-NIM CHAMPIONSHIPSBy NICHOLAS GOODHART

02, 14, 01, 29, 26, 16, 10, 58, 01,15. What have these figures got to

do with the 1967 British NationalGliding Championships? Robin Harper'snightmare after scoring the Cat's Cradletask? Iao Strachan's latest handicappingextravaganza?

This must be arecord for a Nationals aod it's one wenever want to see approached again.

But. of course. the reason for all theraio was high cumulus or cumulonimbusdevelopment, and this (,;ertainly added agood deal of spice to the days on whichwe were able to fly.

space regulations. The fact that it wasnecessary to set tasks which traversedthe airways system introduced an un­wanted element of luck; if the cu-nimwas in an airway, and the dead space inthe FIR, O'ne was defeated. If the oppo­site was the case, one could make goodprogress.

It was. in fact, this situation of ClI­nims in the FIR and clear in the airwaythat enabled me to get to ReaTSby onContest Day 2. A climb to 16,000 ft.,starting near Didcot, followed by a lotof careful dead· reckoning navigation,brought me out., after 40 minutes oninstruments. five miles west of AmberOne near Edgehill at 11,000 ft. AmberOne itself was completely in the clearand. despite the heavy icing, the heightin hand was sufficient to glide clearacross to Bitteswell, where another cu­nim was building strongly.

h is of interest that the ;lchieved gHderatio with ice was about 19: 1 at 50knots indicated. Obviously, if a way ofshedding the ice could be invented, itwould be very valuable indeed. Withoutice 1 would have been able to do 75-80knots along the same glide path.

The lucky break of finding the airwayclear was the main reason I got toRearsby. and the big points lead this~ave me was the decisive factor in theChampionshi ps.

With the large amount of cloud-flyingbeing done. the risk of collision in clOUdwas excessive; this factor was clearlyapparent to all pilots, even disregardingthe fact that there actually was a col­lision. Fortunately the fact that mostpilots had good radio enabled a corn­monsense method of avoiding collisionto develop rapidly. In future Champion­ships (and indeed in everyday localflying where there is a probability of twogliders in the same cloud) we must en­sure that there is a specified channeland a specified altimeter 'Setling for ex·changing height information.

On the ground the Championship wasorganized with the skill which we ,pilots,who have all the fun, have come to takealmost for granted. Task setting, met.,

must be sensibly taught if porpoisinR andheavy landings are to be avoided. Ifpupils are allowe~. to approach at 60knots .plus. surprlsmg phenomena arelikely to occur! From personal experi­ence 1 believe that one of the greatestweaknesses of our instructors is thelack of sta.ndardisation on approachtechniques.

A tragic double fatality in a T-21 haspointed the need for considera'ble cautionwhen flying less sophisticated gliders instrong wind-gradient -conditions. Of flyingin strong winds, the only thing to besaid is: "When in doubt, leave them inthe hangar."

Several shock ropes have come intocontact with various parts of gliders, andtbe Technical Committee are recom­mending a change in length of theseropes. This is just one j))ustration of the"share your experience" principle. Manvfaults in technique and design wouldnever be discovered if accidents wereroot reported.

Instructors instructing have been re­sponsi,ble for fewer accidents than nor­mal. An indication that we are improv­ing? To those instructors who have cometo rest in a cloud of dust and plywood,I would console with the thought thatflying training is as good a 'Way as anyof sailing close to the wind. and that·even in the best regulated circles trainingaccidents will happen.

This. however. does not absolve us ofcur responsibilitY to try and keep train­iog accidents to a minimum.

Winch failures (including cable breaks)are still exacting their toll-seven. to beexact. Two of these ha·ppened to pilotswith over 200 hours as P.I. This seemsto . indicate a tendency amongst ex­penenced pilots to press on in the hopethat the winch will recover power. Un­fortunately these accidents tend to beexpensive. for there is seldom an answerto flying too slowly near the ground.People tend to run out of ideas!

. Far too many pilots are taking off withal~brakes unlocked. I have gone intopnnt about this, already, but wiU reiter­ate that there is no SUbstitute for careful,complete cockpit checks.

Two gliders have been victims of poorground-handling, the resultant blowing­Overs proving yet again that if correctground handling procedures are ignoredor allowed to become sloppy, the

supreme penalty will be paid. Of all theaccidents, blow-overs are the most in­excusable and must directly be attributedto lack of supervision by people :whoshould know better.

The problem of misreading altimetershas arrived to plague gliding just as ithas plagued power-flying in the pastPilots have pulled off aerotows at 1,000ins-tead of 2,000 ft. and have causedthemselves considerable embarrassmentBefore rushing off to design expensivealtimeters that require electricity andother scientific wonders to operate them,it is worth remembering that gliding is asport in which judgment is often worthmore than technology. If a pilot releasesat 1,000 ft. there is no problem if he canmake it back to the field. Using this factas a basis. we can devel€YP a technique tominimise the risk of being out of glidingrange when pulling off. It is recom­mended that instructors teach their pupilsnot only to find the airfield befol'e pull­ing off, but decide 1f the angle looksreasonaible. If it is, then the site is withing,Iiding range. Of course, if the pilotalways releases at 1,000 ft. because hecannot read the altimeter. there is aremedy. I will leave it to our readers towork this out! Tug pilots can help tominimise the risk of outlandings byremaining within gliding range of thesite during the whole of the climb.

A very dexterous crew have discoveredhow to rig a Skylark 4 with the tip!centre-section bell-cranks overlapping,thereby effectively nalving the number ofailerons. Skylark 3's cap also be treatedin this way. Ray Stafford Alien hasissued a note on this (see page 300).

At no small cost it has been provedthat tugs and loose coils of launchingcable do not mix. All tug operators arerecommended to keep a careful watchon those spare lengths of caJbles and longbits of wire removed from snarl-ups.

ELECTRICAL BONDINGBy FRANK IRVING

As most readers will know, a sadaccident occurred last year in which

a pilot. flying a Skylark 4, lost his lifeafter being struck by lightning. Sincethen. it has become mandatory to fitgliders having RG.A. Certificates of Air­wortlliness with a simple form of bond­ing if the cloud-flying category is to beretained. Moreover, a glider fitted withthis bonding has now suffered a light­ning strike: it was damaged, but thepilot received only a very slight electricshock. This seems to be a good oppor­tunity, before the Cu-nims of latesummer appear. to explain the effects oflightning strikes and the objects andlimitations of the present approvedsystem.

Probably the best document on thissubject is Reference I. It is m3!inly con­cerned ,with the protection of the occu­pants of the glider, and it .explores thematter with a wealth of experimentaland theoretical detail. Briefly. its find­in~ are as follows;-

If a potential difference exists betweenvarious parts of a human body, a currentwill flow which will produce variousphysiological effects. depending on theintensity and duration of the current.Ideally. the current should be so low thatthe pilot is quite unaware of it; but atthe worst, the maximum effect shouldfall short of exciting rel1exes or paraly­sis of muscles so as to cause temporaryloss of control of the glider. The currentsand times involved are of the order ofmilliampS and milliseconds. Obviously.if large currents occur, permanentdamage to the body can be caused.

Voltages can be induced in the follow­ing ways;(i) Electromagnetically. 1£ a large and

varying current (due to a lightningdischarge) passes through conductorsin the glider. a voltage will be in­duced in the pilot himself. A typicallightning flash would involve amaximum current of 100,000 amps.,the duration of the flash being about10 microseconds. Shielding the pilotby 8 conductors disposed symmelri­cally around him would usually

limit the induced voltage to anacceptable value.

(oH) Electrostatically. If the .pilot is In­sulated from the glider, and the latterbecomes electrostatically chargedwith a high voltage relative toearth, there will be a potentialdifference between the pilot and theglider. depending on the variouselectrical capacitances of the pilot­glider'"Cafth system. If the pilotthen touches the glider. he willreceive a shock. The screening men­tioned abQve just about suffices toreduce this effect to an acceptablelevel.

(iii) A further effect can be produced asa result of a lightning flash close tothe glider, when .a ·current passesthrough the pilot as a result of therate of rise of voltage during thedevelopment time of the discharge(about 100,000 v. in a few milli­seconds). This also depends on thecapacitan~ of the pilot with respectto earth. The efficacy of the abovescreening in this case is not veryweB established. and the only realprotection consists of covering allthe surfaces of the cockpil with aconducting substance.

Another effect, {lot mentioned in Ref.1. is that various metallic parts of thegl·ider. if insulated from one another, canachieve different potentials, either by in­duction or by electrostatic charge. Largepotential differences can therefore existbetween. say, the control column and therudder pedals, since the associated con­trol runs are often independent. A par­ticularly grave danger can occur duringa winch launch when the pilot. holdingthe stick. achieves some very high poten­tial and then takes hold of the releaseknob. which is connected to earth viathe winch cable.

All of the above relates to protectionof the pilot. If possi'ble. one would liketo protect the structure of the aircraft aswell. Both Ref. 1 and British Civil Air­worthiness Requirements Section Dpropose broadly similar measures: a"main earth" system of conductors is

run along the fuselage and across thewings. "Stricker plateS" at the extremi-,ties of the machine, and all significantmetal components. are connected to themain earth system. Section D providesa more elaborate earth system than thatproposed by the P()lish authqritills, butwith appreciably less screening for thepilot. The main earth conductors speci­fied in Section D seem remarkably small(flat copper strip with a cross-section of0.009 sq. in.). A rough calculationsuggests that, even more remarka·bly,such a conductor' should take 100.000amps. for about 30 mioroseconds. Thiscalculation is very rough indeed. andprovides little guidance about effects ont.he ad.iacent structure. The mechanicalf@rces on the conductors, are likely tobe very large, and the copper would beon the verge of melting. IncidentallY, theheat input reaches the staggering figureof 450 megawatts per foot.

Putting BCAR-type bonding into atypical single-seat glider in the course ofconstruction would involve a weight pen­alty of about 12 lb. and would ,pmbablycost £35-£40. (The Polish weight estimatefor the Bocian is 22 Lb.) Installingsimilar bonding ,in an existing gliderwould be an extremely difficult andc()st-

316

Iy exercise, and the BGA TechnicalCommittee felt that it would not begenerally acceptable as a mandatorYmodification. ,It was. therefore, decidedto concentrate on an inex.pensive andsimple form of bondinp; which wouldprovide a useful measuT.eof protectionto the pilot only.

The type of bonding finally adoptedconsjsts simply of connecting tOl/:ether allthe .control runs which end at levers orknobs in the cockpit, together with anyother significant metal parts with whichthe pilot is likely to come in contact (e.g.the instrument panel). So far as the slowbuild-up, of electrostatic potential isconcerned. the pilot and all c.ontrollevers, etc. will be at the s.ame vDltage,and he is therefore unlikely to receive ashock from this souree (nor from thewiJ;lch-launcIi case mentioned a·OOve). Italso prov·ides some measure of screening,since the pilot is nartly surrounded bvin.terconnected push-rods. cables and theinstrument panel However, as Faradavcages ·go, these components only pro­duce a rather porous one. So there willbe some measure of protection againstvoltages induced electromap;neticallY. butnot very much, and considerable pro­tection against electrostatic charges or

Page 51: Sailplane & Gliding 1967

other potentials anslftj:\ from effects inwhich the times involved ar.e milli­seconds rather than microosec@nds.

The j(lider structure and control runsare not afforded any significant protec­tion by this system. It will no,t. forexample. prevent the aileron cablesfusinj(. The intention. ho,wever, is thatthe pilot should remain capable of takinJ:emergencY action (such as baling-out)should the glider be damaged, and thathe should not suffer painful or disablingshocks in .less extreme circumstances. Theone recent occurrence suggests that thebonding of the Dart successfully achic'vesthese aims.

It is by no means clear that evenBCAR • type bonding would preventdamage to the glider in the event of adirect strike by a major discharge. Get­ting in the way of 100.000 amps. seemslikely to cause some bother, even if itgoes through the earth system ratherihan through control cables. The danjterof loss of control would doubtless beappreciably reduced. but rhe high tem­pera tures attained by the cond uctorsmight well lead to other dama!!e. Allthis. howe..er. is in the realms of specu­lalion.

To summarise. the BGA TechnicalCommittee has tried-apparently withsome measure of success - to providereasonable protection for the pilot at anaeceptal,)le . cosl. But lar!!e electricalstorm-clouds are inherently danjterous;they can ca.use serious damaj:\e to larl1;eaircraft. and the Technical Committee

- certainly would not claim that thepresent bondinJ: renders flight in suchclouds completely safe. We have simplytried to reduce the more drastic effects ofa strike. and pilots who wish to avoid anasty fright and the possibility of damaJ:eto the machine should a..oid suchclouds.

Of course. there is nothin,g to preventa.n owner installing r.eally comprehen­sIve. bonding to J:jve more complete pro­tectIOn. and the' Technical Committeewill. be very happy 10 provide derailedadVice to anyol1e wishinj( 10 do so.

COOK COMPASS MOUNTING MODIFICATIONBy "CHUCK" BENTSON

MOUNTING a Cook compass can bea problem, and the location usually

selected, for want of a better one, ison the side of the canopy above thepilot's e)bow. Disadv~nt<!ges o~ thislocation !Dclude separatIOn from instru­ment area, obstruction, and difficulty injudging angle of tilt acCtlrately. Conse­quently, man~ pilots require an addi­tional conventIOnal compass.

If a mirror is mounted on the gimbalat an angle of 45 degrees to the faceof the compass, the compass can beviewed horizontally instead of vertically,and ean be mounted at the top of theinstrument panel, or on the front ofthe canopy, where it will be more freefrom magnetic influences. The minimummirror size is t.75 ins, x 2.5 ins. Themirror should be directly above the dialof the compass, at 45 degrees, and asclose as possible. The mirror may bemounted by bonding to a piece ofaluminium shaped to suit the particulartype of gimbal fitted to the compass.

In my experience. the location of theeompass on the front of the canopy,with the top of the mirror just below thehorizon, seems to be most satisfactory.The advantages of this modification are:

(a) The compass is most easily seen andscanned..

(b) The angle of tilt can be veryaccurately judged, the compass ateye level, ensuring accurate readingsfor coming out on course or settingcourse.

(c) The indicator needle is seen torotate in the same direction as theaircraft is turning.

(d) When flying in a southerly direction,the points of the compass appear inthe normal sense, i.e. South. ahead;East, to the left; West, to the right.

I did not find it particularly disturb­ing that the numbers on the dialappeared as mirror images, and soonlearned to read them quickly. It wouldbe better if th~ instrument were fittedwith a mirror image dial so that it wouldappear normal when viewed in themirror; also, North could be arrangedto appear at the top of the presentationby reversing the pointer and dial.

I have found that the mirror mountingas described above greatly enhances theusefulness of the Cook compass, and Ibeliev~ that with this modification morepilots would find the Cook compasscompletely satisfactory as a primaryinstrument.

A THOUGHT OVER THE KNITTING NEEDLES

By AUNT MATILDA

IN m~' opinion fox-hunting is on itsway out-probably within the next

twenty years. Further to this (and foreveryone's sake, don't let's start a cor­res~Ddence about it) one basic reasonfor Its being on the way out is not thatthe Great B.P. is concerned about anyPossible cruelty to the fox, but Qecausepeople who hunt foxes are consideredto be a Privileged Class: and nothing~oUld be a grl?ater crime than .that nowa-

ays. UnluckIly for the ordmary com­[non 01" garden fox-hunter, their imagehas been ruined by a minority who con-

sider their superiority when mountedupon the Noble Beast sufficient to enablethem to ride over the countryside re­gardless of crop damage and to' insultthose humble peasants who get in theirway.

Now, Glider Pilots, let us have a littlethink about this and examine your con­sciences.. You, too, an of you, are aprivileged class. (Cries of Rhubarb,Rhubarb, My Old Man's a Dustman,etc.) Let's get that quite straight. Youare lucky en()ugh to have a full comple­ment of limbs, you are not in your

321

Page 56: Sailplane & Gliding 1967

dotages, and you have enough brains tomaster a simple Theory of Flight andread what the A.S.!. says, even if youdon't understand the Rating System. Aswell as this, you have sufficient money.I know you will an immediately fall offyour seats laughing at this idea, but let'sface it, an awful lot of people cannotafford to glide--I mean, they really donot have sufficient lolly, not just thatthey just bleat about it like you lot.Further to this, an even greater numberof people never have had the oppor­tunity and good fortune to become ac­quainted with any flying machines, muchless those extraordinary beasts withoutengines.

So at some time, as you break thespeed limit along the back roads withyour trailer and glider (which you can'tafford, of course), someone is going toask you: "What have you got in thatbig box?" There you are, the bigglamorous Master of the Air in your.little cotton flying suit, your head stuffedwith lofty ideals about breaking rec,ords,and you confront this wretched nig.no~,

doubtless a Sunday driver with all hiSsticky kids, and to amuse your crewand demonstrate what a witty lad you

are, you answer: "An eight-legged polopony", or "a boa constrictor", or a"gir~ffe lying down on its side". Andeveryone laughs gaily except the en­Quirer and his sticky kids, who realisesomeone is taking the mid out of theirdad-who does not wish to again displayhis ignorance and so keeps quiet. Butyou, brother, have made an enemy-nota friend.

For years and years instructors haveemphaSISed to their pupils the impor­tance of being polite and courteous tofarmers. Strange, then, that only lastweek a farmer should have said to me:"If you know of any of those bl ... yglider pilots you can...." (unprintable).But don't let us think only of the land­owners, first priority though it may be.Let us also consider the man in thestreet and future public opinion. Do youknow anything about crocodile hunting?Of course not. Why, then. expect ,everycitizen to know about the subtleties ofyour chosen 'Sport? For your own sakes,give a courteous answer: be helpful.kind and smile . .. with 'em, not at 'em.

"POSSIBLES" COMPETITIONBy ANN WELCH

THE original idea of the "Possibles"Competition was to enable the con­

tenders for the British Team to flyagainst each other in the same tr-pe ofaircraft. This now proved impoSSible toarrange in the short tim~ available, andso pilots continued to use their owngliders.

The Competition was held immedi­ately following the Nationals at Lasham.Although little or no new informationon pilot capability came out of the con­test, it enlarged the rather small sampleof 1967 performance, which was all thatwas possible in the Nationals weather,and confirmed previous knowledge.

The weather for the "Possibles" wasa great improvement on the previousweek, everyone being able, at last. todiscard gumboots. There were four taskdJlYS. the first allowing ~ 300-km. tri­angle to be set. Twelve "Possibles" flewthe task. as well as two hors concourspilots. Of these fourteen, thirteen com­pleted it. The only pilot to land out wasJohn Williamson in th.e new HP-14. Heran into heavy sink on the final glideand ground to earth only two fieldsshort. Had he got in, he would havebeaten the V.K. record by sevenminutes. and the next nearest competi­tor by 17.

The next day provided a 200-km. Out­and-Return. As conditions turned out.this could have been bigger, althoughthe weather area available precluded a500-km. triangle. All pilots completedthe course with flight times between 2~

and 4 hours.On 2nd June the forecast held out a

real chance of a 500 km. triangle. andthis was set. the course being Lasham,Corby Town, Sleap airfield, Lasham.Unfortunately a mass of rotten airmoved in much more extensively thanexpected from the East Coast and.literally, put a tongue out across thefirst leg. John Williamson and DavidInnes nearly reached the first turningpoint. but had to land in very poorweather. So that was the end of the first500-km. contest aHemp.t.

On the last day, the weather showedevery sign of reverting to its previous

32-1

enfeebled variety, although a reasonableperiod of thermal activity was expected.The course set was a flat triangle of 240km. : Lasham. Wylye Bridge (west ofSalisbury), Guildford Cathedral, Lasham,the gliders passing close to base on thesecond leg. The weather did not brewproperly, so the first turning point waswithdrawn to Andover airfield. In almostdrifting conditions everyone set off in arelaxed mood since tbe task was justgoing to provide some pleasant flying,rather than prove much competitively.Four out of the sixteen pilots flying onthis day completed the course-JohnWilliamson, now in a Dart 17. with fas­test time. The others were John Cardiff,Colin Donald and Andy Gough.

The "Possibles" Competition thenended with the meeting to select theBritish Team.

Organizationally. the "Possibles" Com­petition was very interesting. It showedthat a competition of up to fifteengliders flow'n by experienced competitionpilots can be run completely by onlythree pe:>ple apart from tug pilots. Thedivision of labour works as follows:

Person I. Obtajns met., sets tasks,gives briefing, controls laun­ching. logs take-oO's, andassists in start and finishline timing.

Person 2. Prepares briefing boards andturrung - point information.sets up and is responsiblefor timing of start andfinish lines. and providesseorers with log sheets.Assists if necessary in or­ganizing retrieves_

Person 3. Assists in marshalling take­offs, develops and assessesturning - point photographs,works out and producesdaily and final scores, andtakes retrieve messages, ifany.

This is, of course, only practical with(a) pilots who are willing and able tomarshal themselves in the right order,when everyone has radio; and whenphotography is used for obtaining evi-

sibles", it was agreed that all trailersshould stay at Lasham until the gliderslanded. This work~ very well, withcrews driving for eaeh other's pilotswhere this helped. The stay-at-home rulewas relaxed on the' 500-km. day, so thatthere should be no risk of the n:ext day'sflying being compromise<!. In the event,this did not matter. Having crews atbase also helps communication betweeneveryone, due to the extra quantity ofradios on the field.

Arising from the unusually high quan­tity of cloud flying which the 1967Nationals produced, the "Possibles"Competition was run with eommon alti­meter settings, and as far as possiblea common cloud-flying frequency. Forthe future a single cloud-flying frequencyis essential Apart from reducing theactual risk of collisiDn, which is small,it will enormously increase peace ofmind, which in a major championship isimportant.

LIGHTNING AND COLLISION IN CLOUDBy pHILlP WILLS

THE Thursday evening before the startof practice week for the Nationals,

Iustin arrived at home with the D.arttrailer and a face of doom, announcmgthat, to get his Diamond height, .he hadgone into what seemed a decaymg cu­nim somewhere near Banbury, and at21 000 ft. the only lightning flash in thecl~ud had struck the machine.

Possibly bec.ause this last winter wehave all had our contIols bonded, hehimself had only received a slight shock,and Kittv and I were so relieved to havehim back that the damage to the Dartwas almost a pleasure. The lightninghad struck the tip of the metal web ofthe metal {wood bonded spar, about 5ft. from the wing-tip, burning a holethrough the ply bottom surface of thewing, ran to the opposite wing-tip, andburnt its way out through an identicalhole in the ply at the same point there.

This left me without a pair of wingsfor the Nationals, but that is anotherstory, illuminated by the sportsmanshipof Ron Cousins, who provided me withanother pair.

Then ensued the worst and wettestfortnight in gliding history, on the lastday of which the Army, in the shape ofTony Deane-Drummond (Ka-6E) and theAir Force (Paddy Kearon flying anSHK) collided with each other in a cu­nim north of Oxford. Damage to theKa-6E was relatively slight, but with itswing sheared through well aft of what ithas instead of a spar, the SHK was onlyby a miracle brought to earth in onepiece.

Lightning strike and collisions incloud - two of the most dramatichazards of high-peTformance gliding. Wehad better look at them a bit moreclosely.

Within the past six years I can recallat It:ast six cases of lightning strike inc~-mms in this country. In these, fiveaIrcraft were damaged, ,one destroyed,iill~lilots fairly seriously shocked, one

The curious thing is tbat, prior toth~t, I cannot remember any cases ofthiS sort in this country at alJ, but IconclUde this is simply because only in

the last few years has there been anysufficient number of flights in cu-nimsfor the actuarial consequences to showthemselves.

I must do some wildish guesses here,but I should be surprised if during thissix-year period there had been morethan an average of 100 flights a year incu-nims. If this is so, the risk of adamaging strike in these clouds is of theorder of I %. This risk is reduced in ametal aircraft, and by ,bonding the con­trols in a wooden one, but nothing canavert catastrophe in the event of a directstrike. Although the single fatality wehave experienced is insufficient to formany conclusions as to the order ofcatastrophic risk, it seems to me that thissort of general risk figure is altogethertoo high, and nothing can be done aboutit except to keep out of cu-nim.

Coming to 'cl04d-coIlision risks. Ithink we have had two such collisionssince the war, one aircraft lost, nocasualties. In this time there have cer­tainly been tens Qf thousands of cloudflights, So the risk is much smaller thanthat of lightning-strike in eu-nim. But inthis case it is p'ossible to reduce it stillfurther by senSIble use of radio, and theBOA is working on a scheme which, ifpracticable, will soon be promulgated.

I have written these notes in a hurry,to catch this issue of S. & G., so I havenot had time to check my figures as Iwould have liked. But I am anxious toget the general picture over without de­lay, as I believe it to be.

Maps started coming out and A. K.Sunderajan (Birla, Kartik I) and V. B.GUPla (Delhi, Kar~ik II) declared Sultan­pur as their goal, while the other three,V. V. Nanda (Kanpur. Ka-7). F. J.Ghaswala (Ahmedabad, Kartik I) andmyself (Deolali, Kartik 11) declared I.I.T.'Kalyanpur Airstrip, Kanpur, as our goal.I was the last to take off. at 11.15 I.s.T.

At 11.46, cable was released at 1,000ft. (300 metres) and immediately I en­countered 0.5 to I metres lift which tookme to 800 m. in 25 mins. It was hardgoing, and during this time I had driftedto Badarpur, about 15 km. from Safdar­jung. Meanwhile Ghaswala had alsojoined mealJd now we were just tail­chasing each other and allowing our­selves to drift with the win<!. The liftdied out arid we started heading towardsFaridadad. Height got lost rapidly and Iwas down to 500 m. before I could en­counter lift and climb back to 800 m.•only to come down again.

I was down to 300 m. this time whenI saw ripples. in a wheatfield on theother side of the River Jamuna andnoticed a kite soaring rapidly over it.Immediately I dashed towards it. crossingthe river at probably the lowest possibleheight that so far anyone has done, andcau·ght that God-sent lift at 250 m. Thelift was a fairly good one. about 2 m.per second, but very rough, and in 15millS. I wall at 1,600 m. and croSlled theMat branch of the Upper Ganges Canaland struck the main railway line nearWair. A series of good lifts, followedby fast dashes at 60 m.p.h., saw me by­pass Aligarh two hours after my take­off.

From Aligarh I started keeping my­self between the Ca,wnpore branch of theUpper Ganges Canal and the G.T. Roadand was making fairly good progres~when about 15 km. before Mainpuri I

From Mainpuri I had started follow­ing the Canal, but when it bifurcatedand started going too much off mytrack, I left it and once again started acompass course of 120 0

• After I hadcompleted four hours ·of ftight, 'a severe6 m. per sec. downdraught brought medown once again to 300 m. from 2,900m. As the last few thermals were verygood, I had not bothered to take a ther­mal till I was down to 2.000 m. and fromtITis height. when I started looking forone. I could not find any. My only con­solation was that I had crossed 300-km.line for Gold C distance leg. However.at 300 m. a dust devil was encounteredand up I went in -I to +6 m. per sec.rough lift. The lift took me to 2,000 m.After one more thermal I saw the hangarand UT. Campass 10 km. away andmade a straight dash for it from 1,600m. at 60 m.p.h.

Flight over, a feeling of joy and ananti-climax were experienced. It wasSunclay and there was no one near by.Mter some time a Chokidar was see;]and I called him to come and help meto take the glider to the hangar. A callwas sent to Area Control. Delhi andDelhi Gliding Club through KanpurFlying Control. and then I was taken tothe visitors' guest hostel of I.I.T. by Mr.J. W.

HOW GLIDING BEGAN IN TANZANIABy COLlN PENNYCUICK

I WE.NT to East Africa to see the wildbeasts and birds in the Serengeti

National Park, but this proved to be lesseasy than I thought. Covering the 4,000­odd miles to Nairobi took 12 hours. butthe further 200 miles to the Serengetitook 5 days as it turned out; not, of course,plodding across the wilderness. but wait­ing for an .aeroplane. staying luxuriouslymeanwhile with Touy Hyde, the C.F.I.of the Nakuru Gliding Club. I was notsorry to get in this way an unlocked-foropportunity to visit this celebrated club.the hospitality of which is well known toS. & G. readers from the accounts ofvarious visitors.

I went u.p there on a Saturday andmet Rim Molineux, who was wheelinj!out his brand new.. immaculate Ka.-6.which he had only had for 3 weeks. Ipaid it a few well-deserved compliments.and to my ama2;cment he strapped meinto it and launched me. You can't bemore hospitable than that. It was 4 p.m.and Bim apologised for the state of thesky, wb·ich, he said, c().IJld hardly beconsidered soarable. The cumuli hadflattened out and there was no sunshinewithin reach of the winch launch. How­ever, I found some weak lift at 800 ft.above the ground, and a(ter some care­ful scraping it built up into a brisk ther­mal. I seemed to get no nearer c1oud­base and became suspicious of Rim'svario. but when I eventually got there(~t 14,500 ft.) I found I was going UJ)lIke a rocket-it just took a long timebecause it was so far to go, even withthe ground being at 6,000 Ct. I cruised~apJ)iIY around at 13,000 ft. plus for an

OUr or so admiring the scenery. andeventually fumbled my way down shortly~efo.re sunset. After this promising intro­

UCUOI'i to East African gliding I had to~cllO~ a pressing invitation from BrianC ~k:'lDS (now Tony Hyde's successor as

. .I.) to stay. and get on a nocturnalbfs back to Nairobi to catch my acro­I' ane to the Serengeti.N~ccording to the original plan, the ex­b uru T-31, which was being bought~r Hug~ Lamprey, the Director of the

engett Research Institute, was to have

been aero-towed over there the week­end before I arrived. but they had to doan aero-towing experiment, which wentall right, and then they landed, and therewas this ditch. and. well. I went to seethe Insurance broker in Nairobi. whowas very helpful and said everything wasbeing done that could be done; but itwas a fact that there was no T-31 in theSerengeti. This was not a bad thing as itturned out. as I spent a busy three weekslearning the names of the various beastsand birds, eSJ)ecially the vultures andother thermal soarers. I also weighed.measured and de-rigged a few. andlearned how to move around withoutgetting eaten, which is very important inthe Serengeti.

began to fly in Nairobi, and about 7thJanuary or so we learned (to our care­fully concealed astonishment) that theT-31 was once again airworthy. Veryregretrnbly, however. no tug was avail­able to bring it across the 200 miles ofprickly wilderness separating it from theInstitute's base at Seronera. There wasnothing for it but to go and fetch thething ourselves, which was feasible asthe Nakuru Club had rashly offered to,lend us their trailer. At five in the mom­ing on the 8th we [boarded a LandRover and set off along the road. whichmay sound a straightforward thing to do,but I should explain that the ternl "road"in East Africa has a somewhat widermeaning than is usual in the BritishIsles. Roads vary from the tarmac kindwhich you just belt along, through dirttracks to chains of slithery sandpitswhich you negotiate, mostly sideways, iDfour-wheel crawler.

We ,picked up the glider at WilsonAirport, Nairobi. I asked if everythingwas there and examined ,it suspiciously.Struts? Yes. Wires? Amazing quantities.There were about the right number ofpins. all with safety pins. Were there anyinstrument panels, I asked. Ah yes, theysaid, the instrument panels~well, theywere in Nakuru, but could they send

them? We would get them in a week. Iwould only be there another week. Ipointed out, so we aIL reflected on thissad fact and eventually we shruggedphilosophically and set off.

For 40 miles we sped along the tarmac.in holiday mood, after which our roadleft the main road to cross the bottom ofthe Rift VaIIey, which is about 30 mile,Swide at that point. This -was one of theworst hits of "road". roasting hot. andmarked by tall columns of dust, at thebottom of each of which was a vehicleyawing slowly from side to side in th"sand, mostly in bottom gear. We bumpedand crawled painfuIIy across. greatlyhindered by a light following wind.which engulfed us in our own dost cloudwhenever we slowed down a little toomuch. so that we were forced to acceler­ate blindly into the opaque murk 1norder to get out of iL The sun was set­ting as we started up the slope at thefar side of the Rift Valley, congratulatingourselves on having passed the worst.

It was then, as night fell. that thewheel fell off the trailer. It did tills bywriggling around on the studs until theholes were so enlarged that tije nuts justwent through them, and tben it fell off.we had to admit defeat, and. after prop­ping up, the axle, removed the hub with

Page 65: Sailplane & Gliding 1967

its tormented studs, so that Hugh couldtake it and the wheel back through thesand bath to Nairobi.

None came as it tumedout,and I spent the night and much of thefollowing day inside the trailer shelteringfrom the sun and dust, which I after­wards regretted when 1 learned that theMasai usually investigate any unfamiliarobject by stickoing their spears through it.Hugh returned about 3 ·p·.m. the dayarfter the wheel fell off, by which time Ihad nearly finished the iron rations (abag of nuts), and greedily devoured thesandwiches and orange pop which hebrought. The Ford people it) Nairobi haddone a magnificent piece of surgery onour hub and wheel which we fitted backon and found as good as new. Onceagain, as night fell, we clambered up, theRift Valley escarpment and pressed oninto the nighL

The going was somewhat better andwe made good time to Narok. afterwhich I took over. We had a nastymoment when two rhinos appeared inthe headlights. one of them cavortingabout just beside the road. The road wasquite good here. but surfaced with loose,grave!. and when I saw this rhino Istupidly hit the brakes. causing the LandRover and trailer to start snaking. Hughsaid very clamly, uKeep going straight"and at that the Land Rover straightenedout. more in response to Hugh's willP<?wer than because of anything I did~lth the controls. The rhino luckilyPivoted round to point away from theroad Just as we passed. and if it chargedus it missed.

IWe went through Keekerok, the last

P a~e in Kenya, at about 10 p.m., afterwhich the «road" degenerated into arUtled track. We raised a ragged cheeras we passed the notice board markingthe frontier, making Hugh's T-31 the~st glider to enter Tanzania-, and also

the Serengeti., which begins at the fron­tier. We stopped for refreshment at thesource of the Bolagonja River, a finespring set about with trees. and crashedthrough the bushes, torch in hand, to fillour water flasks. The place smeltstrongly of bUffalo. which made merather nervous, but Hugh knew some­how that there weren't any around.Further on we were .delayed momentarilyby a lioness who insisted on walkingrather slowly in front of us up themiddle of the road. and another timeHugh. who had taken over again,stopped and whistled tlp- a leopard.which came right UP to the Land Roverin the light of his torch.

We arrived safely at Seronera at 3a.m. on 10th January. which was a verysignificant day -in the history of Tan­zania. When we woke up we got theT-31 out and rigged it on Seronera Air­strip. As the Scientific Council of theSerengeti had met a few days before. theadmiring crowd which assembled towatch contained a number of d,jstin­guished persons, including. the Directorof National Parks. the Chief ParkWarden and two professors from over­seas. Seronera Airstrip is a mile lonf:.and we had laid out 1.200 ft. of fencingwire as an auto-tow line. To the up­wind end of this we attached a Toyota(a species of Japanese jeep), and to theother end the glider. The Toyota wasdriven by Hans Kruik. a Dutch zoolo­gist known for the dash and precision ofhis bush driving in pursuit of the fleet­footed hyaena. on which he is the lead­ing authority.

The sky was nicely sprinkled with.cumuli. and the only flaw in the scenewas the absence of an instrument panel.

Luckily I happened. to have brought aCosim in my luggage, whieb I had tapedto the bottom of the hole where thepanel should have ~en, and also analtimeter. which I stowed down the- sideof the cockpit where I hoped I would bea,ble to get at it. I did not consider thelack of an AS.I. a serious drawback,what with no speed-to-f1y ~ale on theCosim.

The launch was a little slow, but onceI got airborne I went up all ri~ht. lean­ing OVer the side to watch the Toyota'sprogress. There was no time to fish thealtimeter out of the bih~~ to check mylaunch height. but Hugh said it lookedabout 700 ft. On the way up I noticed adust dev'il to one side of the run andabout half way alonR. so immediatelyafter release I turned and made for it. Ifound weak. lift and circled carefully,getting a:bout 2-3 green on the Cosim.With persistent scraping the eminent.gentlemen below dwindled into littlespecks like ev,erybody else. and soon Iwas at 12,500 ft., having to duck outfrom under the clouds to avoid gettinllsucked in.

taneously_ The other animals. mostlyantelopes of various kinds. giraffes.hyaenas, ostriches and so forth, juststand around on the run, but mostlystep aside to let you pass. We had nolions on the run while I was there. al­though there are plenty armmd. but rgathered the thing to do is to look themstraight in the eye and keep going. For­tunately the occasional itinerant elephantswhich come to push over the trees mostlystay along the Seronera River. nearlythree-quarters of a mile from our run.which is just as well, as an obstreperouseleph3'nt on the run could came a verypoor launch.

Nimbly avoiding an hazards. we gotour launch height up to 1.200 ft. a.g.1.(the ground is at 5,000 ft.), and Hughdid some .lengthy soarin~ flights. Oneevening we did some dual in order to gethim his Bronze C. The first circuit wentall right, but the second launch wasrather hurried as there was a cu-nimapproachinR. As we went up the launchI saw that the rain was about a mileaway. and part of the cloud was over us.We got a splendid launch. the best wehad ever had two-uP. and after release I

Page 67: Sailplane & Gliding 1967

was surprised to see the altimeter s~ootUP another 200 ft. when I tapped It Im ntioned thiS to Hugh, who said thegre n ban appeared to have stuck at thelOP of the tube, and then I noticed thatthe ground seemed to be receding inrather a striking way.

Now, getting sucked into an Africaneu-nim in a spoilerless T-31 with nooxygen or J)araehutes is not my idea ofa good idea. "Let's get out of this," Isaid. This seemed a straightforward planat the time, and Hugh turned and droveaway from the storm at 60 knots (we hadan A.S.I. by this time). Mler about twomiles of this hectic progress. with nosedown and wires shrieking, we had gainedaboUl another 50 ft., and I was gettinjl:nervous in case we suddenly flew intoturbulence at this speed, which is ratherfast for a T-31. I decided to try anothertactic. and, taking over, I appHed 70degrees of bank and full top rudder, andstalled it. We gyrated lopsidedly for abit and at last the altimeter began un­willingly to unwind. At 800 it. I deemedit safe to head back towards the air·strip. and, of course. we didn't make it.Hugh neatly sidestepped a nasty rash ofwarthog holes, and landed very smoothlyon an animal·free piece of ground. Welugged the ldider back to the airstripthroulth the rain. and kept further awayfrom cu-nims after that.

The reasons for my visit to Seronerain the first place were ornithological. andI was disappointed to meet only one ortwo birds on my first soaring flight. LaterJ watched Hugh soaring along withvarious vultures. a secretary bird, and alanner falcon, which he identified for meby radio. and in due eourse I soared withvarious yultures myself. If the vulturesWanted to gain height they took non~tice of us. and went past us up themIddle of our circle, but often theywould formate on us. Sometimes theyflew behind or to one side (}f the ldider,and a favourite place was a few feeta~ove the wing, looking over the pilot'ss oUlder-at the variometer, I suppose..

The vultures have wing loadings abouta t~lrd that of the T·31. and their aspectratios are arouod 7 or 8. This combina­Hon is forced on them, I suspect, by theneed .for adeQuate tak'e-off performance,:nd In s~aring both wing loading andspect ratIO are unduly low. They are

very ~ood at sitting in narrow cores; even

several thousand feet above the ground,but are only about as good as a T-31 ina straight Idide. Various species of vul­tures and other birds habitually soar upto c10udbase (usually 5,000 to 7,000 ft.a.g.!.) but when searching for food theyoften cruise about in straillht !-ines a1about 500 ft., putting their feet down.presumably to act as airbrakes, when theyfly through lift. They have an amazingability to maintain beillht a few hundredfeet up· without cirding, and th.ere is aneagle called t1:le Bataleur which special­ises in, this, and seldom goes up in ther­mals in the conventional way. Allvultures are indefatigable scrapers, andwill circle do~edly in any scrap of tur­bulence as low as 50 ft. As soon as onegets away in a decent thermal, othersusually appear like mallic from all sidesand join it. showing some, but by nomeans absolute respect for the estab­lished direction of circlinll.

One other thinll- I don't think theysmell thermals. I dissected a few, and ifthey had a sense of smell I don't thinkthey would be able to smell anythin~except themselves. The Serengeti ther­mals are not particularly smelly anyway.

Nympsfield 17th·25th June

THE 33 competitors at this year'sBristol Clul!lcompetition were only

able to fly on two days out of a"possi1>lenine-and o,ne of these was a 1~5 maxi­mum-point contest! A succession oftrougbs and fronts that advanced, slowedand eventually stopped over the Cots­wolds brought impossible gliding weatherin the middle of flaming June. Pilots andcrews took to hydrogen ballooning, golf.bird-watching at Slimbridge and increas­ing the bar profits of the Lulsgate Arms.

BOOK REVIEW

GLIDING: A Handbook on Soaring Flight, by DEREK PIGGOTI. Publishedby Adam and Charles Black, London, 1967 (2nd Edition). Price 30s.

THE revised edition of Derek's book, like the first, is quite excellent; it is ameasure of its excellence that many of the chapters written ten years ago are still

entirely valid and have needed no alteration. It would, indeed. be alarming for manyof us. schooled in the Piggolt tradition, if we discovered at this stage that Derek hadsuddenly developed profoundly different views about circuit planning, turning. land­ing. etc. For the most part, it is reassuring to find. the earlier chapters are reprintedjust as they were. with occasional minor alterations of wording and a few briefadditional paragraphs.

Important changes have been made in some of the later sections. Moderntheories about thermals are incorporated, with an interesting diagram on page 141that might, perhaps, have been better supported in the text. There has been someessential revision of the instrument chapter, and, of course. the J.S.W. glide calculatoris given ,a well-deserved page. The paragraphs on lightning have also been chanll;ed,but the dangers were by no means ignored in the earlier edition. so aga·in the altera­tions are mainly of emphasis.

There is no chapter, nor appendix, on powered training; perhaps it is too earlyfor this, though it won't be surprising if the next eDition has (0 be quite different. Itis, however, not too soon for chapters on the technique of flying with flaps, para­chute airbrakes and the use of radio. These are absent. It is therefore probably nolonger quite true to say the book comains "everyth,ing the glider pilot should know".It remains a thoroughly dependable standard work, well produced with many newphotographs, and will undoubtedly enjoy a continued success.

Svaeftyve Hanbogen" by P. H. NIELSEN, P. TRANS and P. WEISHAUPT. Pub­lished by Flyv's Forlag, Copenhagen, 1966.

T'HIS "Sailflyiog Handbook", sponsored by the Royal Danish Acro Club, is afull-blown book of 350 Large pages printed on high quality paper. It starts with a

lavishly illustrated review of sailplanes of various types, including a two-pagedetailed drawing of the Dart reproduced fram Flight, and notes on internal structuraldetails. It goes on to cover aerodynamics, navigation, club organisation and equip­ment, safety, instruments and the many other aspects of gliding.

Meteorology gets the longest chapter with 56 pages, and includes tephigrams.One looks especially for the writer's ideas on that controversial subject, the structureof therma'1s; he draws a continuous airstream from the ground up to and into acumulus cloud, but in a section on clear-sky thermals he refers to them as "bubbles"with a short life of 10 to 15 minutes. Evidently a disciple of Georgii, he also classifies'''high- thermals", "evening thermals", "wind thermals" and "ocean thermals".

'The bibliography starts with Cloud Reading for Pilots" by Ann Douglas (nowWelch) and includes books by Ludlam and Scorer, Piggott, Stafford Alien, Wallington,and Lorne and Ann Welch.

CORRESPONDENCEPROFESSIONALISM

Dear Sir,J feel impelled to point out some fallacies lev·ident in a recent letter from Mr.

D. Carey (S. & G., April. 1967) regarding his attitude to private owners (P.O.'s);

338

Page 73: Sailplane & Gliding 1967

I admit to having joined this exalted class recently, after six years of workingtowards it, so undoubtedly I am prejudiced. too.

Of course, P.O.'s spend more time in the air, having paid for it. However.they generally require of a club the minimum of effort-usually one launch withluck. The wear and tear that club equipment and personnel undergo is almostentirelY the result of training procedures which involve hundreds of circuits andslogging retrieves.

In some cases, P.O.'s are to sQme extent subsidised by the effort of clubmembers. Generally. it's the other way round. P.O.'s generaJly form the backboneof clubs (even the BGA!); they provide instructors, experience and incentive. Thetrue "average solo pilot" that Mr. Carey writes about is all too often a personwho rolls up at the week-end and unfortunately misses out, but at this stage hisdub activities cease. A nucleus of devoted souls run most clubs, and do all thework:. This nucleus almost always includes P.O.'s (who have the biggest stake inthe well-being of their club). along with the most enthusiastic of the club solopilots. In many cases, the average week-end pilot's contribution to club activitiesis a moan that an aircraft wasn't made available to him at his leisure.

I am sure that, taken as a whole OVer all the people who require club ·effortexpended on them, the P.O. most frequently returns to the club value for effortexpended. I also realise that some hard-working solo pilots do get a raw deal. Mr.Carey, in his enthusiasm to capitalise on class distinctions, has forgotten the largenumber of people who join clubs, dabble at training, dabble at soaring, and grumblea'1l along that life hasn't been made easier for them, whilst makjng. no effort tobring this about. Ours is a sport requiring dedication and some sacrifices, whichis unfortunate. But until this situation changes, Mr. Carey's efforts might well bedirected more usefully towards eradicating the tremendous wastage of voluntaryeffort inherent in club operations (as he said previously: S. & G., Oct., 1965),instead of trying to merely make money out of many who provide that effort

Many people can easily become private owners if they are prepared to makesome sacrifices, unless, like Mr. Warren (S. & G., Dec., 1966), they refuse to settlefor anything less than a Sigma or HP-II. I get weary of people who won't flyan Oly 2 because it is so inferior to a Dart. Olympias hal'e done Gold Cs (1 didmy 300 Kms. in one and it was a piece of cake, with the right weather), and Ihave heard of people who have actually worked overtime, and given up smoking,to get into any Oly syndicate! The answer to many grumbles can often be foundin the argument of the grumblers.Australian National Univ~rsity. Canberra J. D. PICKED-HEAPS

OUR LOVE OF FREEOOMDear Sir,

I believe gliding enthusiasts are endowed above the average with a love offreedom. The British movement has until recently contrived to maintain acorres!'onding freedom in its administrative organisation, with a minimum ofbureaucratic regulation and interference, whether from inside :lr outside. This isnow changing.

Some people will justify the changes by pointing to cban~s in the design ofmodem gliders, changes in the attitude of and affluence of modern glider pilots.or even changes of Government! It is my contention that none of these factorsrelal.ly justifies those changes in the organisation and practice of the sport ofg Id109 which stultify freedom.

. Bureaucracy is not a monopoly of Civil Servants. Many of us must admit -to~n lOner urge tQ orderliness (though it's frequently unsatisfied). When it comes to

uman affairs, orderliness can only be assured by regulation-and this is wherethe cla~h with freedom occurs: Designated Start is more orderly and efficienttha~ Pilot Choice. Safe standards of !,ilotage or aircraft airworthiness are mOreeaSIly achieVed by the. adoption of uniform instructing or inspection methods; thesemust. then be enforced by regulation-in ever greater detail, from braided copperbondlOg wire· to Bronze C aerodynamics exams. If efficiency is the sole criterion,an organisation will be better and stronger if it is finally controlled from the centre

-~ven a "National Centre".For most people these problems really resolve themselves into the questjon

of where to draw the line. As with art, a better line will be drawn if one standswell back and views the particular question in the perspective of gliding as awhole. Many detailed regulatory requirements, while appearing desirable in theimmediatt' close-up context of the specialist problems they're designed to remedy,are seen as tiresome, time-wasting and nit-picking bureaucracy when examined inthe sunlight of .the big practical gliding world outside.

GLIDING HAZARDS THIS SIDE OF THE IRON CURTAINDear Sir.

Now that Great Britain stands on the threshold of joining the Common Market.it's timely perhaps fol' glider pilots to be informed cf some of the risks tbat canawait them the further side of the Channel in an entirely different world of adminis­trators.

On Thursday, 27th April, 1967, at 13.40 hrs. iocal time, a member of the GoldenRiver Aviation Club, finding thermal conditio-ns promisin~, set off in a club BreguetFauvette from Wevelgem airfield on a SO.km. distance fllgh,t to complete his SilverC. A northerly IS-knot breeze sped him on his way, and some three hours later hetouched down without mishap 200 kms. further, close to the Paris-Lille auto-routenear Scnlis, wh·ich lies 45 km. to the north of Paris. He dutifully informed the FrenchGend<lrmerie and the French Customs of his presence, an{! settled dc,wn with apleasant feeling of accomplishment to· await events, which were not long in forth­coming, though along some rather unexpected lines.

A phone call from a French Excise Officer in Paris ordered the Gendarmerie atSculis to arrest and imprison the pilot, to confiscate and impound the glider and towa·it their arrival. Our young club member was taken to and put into Senlis jail.where he passed the night and the better part of the following morning, deprived ofhis tie and belt as a common malefactor and with nothing to sleep -on but a hardplank. Food was provided after ,insistence through the kindness of a gendarme's wife.

Next morning he was taken in front of the magistrates and charged as a contra­ban<Jist for introducing into France undeclared merchandise in the form of a glider.He was released pending trial of the case seven weeks later, and the glider remainsconfiscated in the meantime.Golden River Aviatioll Club,WevelRem Airfield.

THE TEAM FOR POLANDDear Sir,

The method for selection of the team disclosed in S. & G. for June/July canby no process be described as democratic. The system outlined is a closed shop.Members of Parliament are elected by the franchised, not by a small group of M.P.'s.

It is time that justice must not only be done, but must be seen to be done,and everyone knows of ways of influencing or channelling a voting system of thetype described. I had hoped that my letter to S. & G. would have been publishedin this issue.

It is not a matter of making a better choice; how the remainder of the teamis selected is immaterial, or their order of precedence. Any of our top pilots arecapable of winning the contest. It is precisely for this reason that the reigningNational Champion should have a flying place in .the team, whoever i.t happens tobe. The over,iding point is that it has happened! What objection can there beto making the Champion an automatic selectIOn?Newbury, Berks J. E. CRAMP, A.S.L.A.E.T.

POWERED TRAINERS AND THE SCHEIBE "MOTORFALKE"Dear Sir,

r should like to express some opinions regarding powered sailplanes to readersof SAJLPLANE &. GLIDING, with particular reference to the "Powered Trainer Co-ordinating Committ~ Report" appe~ring in ~he April-May issue: ..

Firstly, concern109 powered sailplanes m general. A special classificatIOn forsailplanes with en~~nes was first establi~hed by the German autho:ities in 1956-57,and this has fac~latated development ID Germany. We at Schelbe FlugzeugbauGmbH have been interested in this development and. having built about 100 poweredsailplanes to date, can speak from some experience.

Emphasis can be placed on soaring performance, through retractable powerplant or t.he -like. ("pure" .sa~lplane with ~ower). o~ alternalively more on the pow<:redtlight regime, With the hmlllng case bemg the hght aeroplane capable of soanng;between these, the whole spectrum of intermediate forms is also availa:ble, e.g.. prac­tice sailplane with power plant. Our hitherto existing Motorspat:z and Motorfalketype are laid out more or less in the latter direction, while our new SF-27M. de­veloped in co-operation with A. Obermeier (llIerschwalbe), is decidedly a hillh­performance sailplane with engine.

It ·is our point of view that the powered sailplane should be designed to soar, andalso to do some things the plain sailplane cannot, such as:

Launch itself.Fly .as long as, as high as and as far as necessary to contact atmospheric lift,

and if this is not found to fly anyway.Retrieve itself from overland flights.Fly in and out from under airways or other areas with restricted operating

altitude.Self-launching and self-retrieving capabilities imply the emancipation of severalhelpers who would probably rather be soaring themselves, elimination of equipmentsuch as winch or aeroplane which burn fuel at a much more rapid rate than thepowered sai,lplane and a saving in the time needed to set all this ancillary machineryinto motion. Even without this support, the degree of utilisation possible, i.e.. thenumber of flights and flight hours which can be flown per day, is considerably greaterfor the powered than for the unpowered sailplane. In short, a successful poweredsailplane design allows more soarin~ a't lower cost.

Fortunately, a few firms such as Nelson in the D.S.A, SUTvol in France andSolo-Hirth in Germany hav!: been interested enough in this problem to produceen.gines specifically intended for powered sailplanes. Experience in Germany with theHlrth F·IO engine of 26-28 h.p., developed by &>10 in 1960-62 and built by Hirth­Benningen, has been quite good since its introduction in 1962. The F-IO powers theMotorspatz, Motorfalke, Krahe and SF-27M.

In their report, the Committee compared various hypothetical or still untriedpOwered trainer designs ("ideal project", "Er·ic Reed specification", R.F. 5) as wellas. ~everal light aeroplanes (Beagle PUJ}. Condor, Jodel D-117, Boelkow Junior), butarbnrarily dismissed the Motorlalke with the comment "unacceptable climb perfor­Thance for ab-initio training". We challenge this exclusion as absolutely unwarranted.

e fact is that the Motorfalke is the only machine considered which has actuallybeen shown in practice to have suitable flying characteristics. including ability tothke,off satisfactorily f~om most airfie.lds, for use in training !lliding pilots. It is truet at the Motorfalke, WIth a rate of chmb of 250-300 f.p.m. With tWQ occupants, fallsff: short of .the 500 f.p.m. called fa: i~ the "ideal" trainer speoificat~ons; ho.wever.c 1mb an~le IS, after all, the more slgruficant parameter from the pomt of 'VIew ofsafety, and in this respect the Motorfalk.e compares very favourably with the light:ero~lanes. such as. th~ Juni?~, being consi~ered. (The sine of t~e dim~ angle isIqua to the rate of climb divided by the lIlrspeed and, With a wmg-Ioadmg of 5.5a~s./~. ft. (compared with around 13 Ibs./sq. ft. for the Junior), the Motorfalke fliessa·saalplane speeds.) Th.e· Motorfalke has the low induced and parasitic drag of asailplane (wing aspect ratio over 15 compared with about six for the JuniC'r) and is

me 300 Ibs. lighter at gross than the Junior; quite obviously, a rather more341

Page 76: Sailplane & Gliding 1967

sta.rtling difference in !(Iide angle, to say nothing of sink rate, would become evidelltthe instant the engines were switched off (or failed !).

In our opinion, one stands to gain considerable advantages by utilising a"powered trajner", i.e., a powered sailplane; however. ODe should strive in trainingto fly the trainer as much as possible without engine-to soar-and it ~bould there­fore have good soaring characteristics. It is our judgment that the engine power andclimbing reserve should not be too great, so that the milisatioD of lift remains ofinterest to the pilots. Our own view js diametrically opposed to the Committee'sadmittedly "surprising" conclusion that "the Qverall trend becomes progressively lessfavourable the closer the a·ircraft's characteristics approximate to those of a IIlider".In fact, we find nothing whatsoever among the results presented in Appendix 2 tosupport this conclusion. True, Col. 7, Fig. 2, gives smaller values for "Power FlyingTime Required Hours" for the aeroplanes, but these figures were derived by thearbitrary procedure of "'assuming six hours' total flying, power and gliding, in eachcase, and deducting gliding as aero-tows at 20 mins. each". In other words, theCommittee in deriving these figures supposedly revealing the estimated effects ontraining efficiency of differences in flying characterisLics of various possible trainers,did so on the premise that these differences would not affect the number of flighthours required. We can find little justification for th,is or many other assumptionsupon which the Committee's conclusions were based.

The inexplicable exclusion of the Motorfalke is especially peculiar consideringthat it is the only aircraft meeting the low airspeed requirement of the "ideal"specification, and that it has the glider flying characteristics which the Committeeconcludes are "essential" for teaching almost all ab initio exercises. While the Com­mittee was apparently very well informed concerning the R.F. 5, we wonder if it wasaware that the Motorfalke is priced at less than £2.000 ex-wor·ks, including instru­ments. Had they been fully advised of the facts .. their "value analysis" would un­doubtedly have shown the Motorfalke to be the "best buy" as a powered trainer forgliding, certainly among aircraft now flying.

In contrast to speculations a-bout designs and procedures which are still umried.a substantial body of supporting fact concerning the Motorfalke has already beengained sin<;:e delivery began in 1965. Results of a questionnaire returned by 30Motorfa!ke owners in autumn 1966 confirmed that a substantiae! proportion of flighttime had been spent gliding withaut power. Some 9,000 flights had been made UP tothat time. mostly self-powered (the Motorfalke can also be winch-launched withthe engine stopped). With about 4,600 flight hours, approximately 2,900 were withand 1,700 without engine assistance. Some 300 pilots were estimated to have par­ticipated in the flights.

A new vel'sion of the Motorfalke, with modified configuration and <;:onverted VWengine. is now being developed at Scheibe Flugzeughau. This machine will have ahigher rate of climb and will incorporate other improvements making the aircraftstill more ideally suited for use as a powered trainer.Dachau, West Germany

THE CHAIRMAN OF THE POWERED TRAINER CO-ORDINATING ();)MMITIEE commenas follows: ODe welcomes Herr Scheibe's comments because they reflect vi.ewbased on eXlleri~nce, of someone who is making a very significant contribution tIhe cause of the motor g·lider.

Much of what he says concerning the wider issues is strongly supported by aarticle which wm appear in the next issue.

On the question of the report and its exclusion of tbe Motorfalke:I. At this stage my committee is only concerned with the selection of a suitabl

"self-launching" aircraft for glider pilot ab-initio training-nothing more.2. We have good reasons, based on our own practical experiences, for the rate 0

climb requirement.3. The final paragraph of Herr Scheibe's letter suggests that in spite of hi

criticisms he does not altogether disagree with our findings. May we please havmore information from him soon about the new VW-engined Motorfalke?

CLUB NEWS

C LUB NEWS this issue concerns itself with Ilews of what has been going onin and aroUl)d the clubs whilst the Nationals were going on at Lasham. We

would like to have more photographs in this section, so if you have anythingsuitable we would like to see it.

Copy for the October-November issue should reach me, typed double spacedon foolscap, not later than 16th August. Copy for the December-January issue bythe 18th October at 14 Little Brownings, London. S.E.23.19th June. 1967 . YVONNE BONHAM (Mrs.)

Club News Edi/or

ALBATROSS

A T the time of writing, the future ofthe club is still in the balance. We

have a firm offer of 50 per cent fi.nancialaid from the Department of Educationand Science, but are awaitin.~ a decisionon the 25 per cent local authorities pro­portion of the total.

We have been flying from our presentsite for nine months and, as anticipated.it has become obvious that we canDotextract the maximum value from ourrjdge unless the Club expands. At Easterwe were faced with the frustrating experi­ence of seeing our sole T-31 remainin~

airborne for average flights of 10 minutes(from 650 launches). leaving an idlewinch with no other aircraft to launch.The club's first C flights were madeover the Easter weekend, by Ray More­croft and Fred Sloggett, and althoullhsuch flights might not seem outstandingevents to other wetl-established clubs.tbey have inspired the Club Committeeto seek a speedy solution to the prob­lem of increasing our flying potential.

At the May Committee Meet·ing. dis­cussions centred around the possibilityof purclTasing a T-2l or similar aircrafton a syndicate basis, and also me!hodsof erecting a portable-ty·pe hangar. whichhas been offered on a rental basis by a

346

firm of scaffolding specialists. If theseprojects are actioned at our June meet­ing we anticipate a rapid increase inour airborne time. as we shall double ouraircraft availability and no lon,ger haveto carry out the daily task of rigging andde-rigging,

To improve our launching facilities.Bill Dyer, our Treasurer. who holds acurrent PPL, has purchased a part in­·terest in a Tiger Moth which is soon tobe fitted with a hook. It will be based atRoborough. but we look forward tore~ular visits by it to our site.

On the social side. we have intro­duced a monthly get-together at variouslocal inns. Since our clubhouse is at thesite. about 25 miles from most members'homes, and does 110t possess a bar. theselocal gatherings are proving most popu­lar (especially with the landlord of theselected rendezvous).

We were honoured to receive a visitfrom John Williamson on behalf of theBGA Instructors' Panel. and regret thathe chose a day when the little greenmen also decide.d to call. We can. how­ever, confirm that they were not LockinggreQ1lins, as they arrived well beforeJohn. Everything happened that day tomake it one of those we try 1101 toremember. The tractor broke do,wn, thewinch becam.e highly temperamental and.

Page 81: Sailplane & Gliding 1967

as an encore, the aircraft deveh)ped apuncturc. It must be difficult to introduceJohn to something new in gliding. butwe certainly can claim fame in thisrespect. as it was the first time he hadever helped to repair a puncture on aT-3\. It was with a sense of achieve­ment that we eventuaIly saw John air­borne. and proved that we do occasion­ally fly .from our site. We enjoyed havinl!John With us, and greatly appreciate hissound advice regarding our future aims.

Now that the holiday season is inmotion. may we once again extend awarm invitation to all gliding types whomay -be on holiday in South Devon. Oursite is bordered by outstanding coast­line belonging to the National Trust. andeven if you only view it from groundlevel. it is well worth a visit.

F.C.S.

BATH AND WILTSAT the fifth AGM our Treasurer an-

nounced that he relUClantly advisedthe committee to increase fees for thesecond year in succession in order tokeep our heads above water.. Continuing its programme of expan­

sion the club had experienced a year ofheavy outlay on equipment and alsosuffered a hard knock by being unable tosell the Kranil;h through it being de­c~red unairworthy because of gluefailure. Herein lies an object lesson forother young clubs. Don't buy cheap air­craft. It rarely pays off in the long run.

Our sec(:md; soaring week of the year.held to colllcldt: With the spring holidayproved a great success. The recently ac2QUlred Skylark 3F is turning out to be avery good buy and is putting in a lot ofhbts and co~seQuently bringing in valu­a e revenue ID the form of soaring feestoeam its keep.

During the week a number of Silver:W1 B{onze legs were flown. The greatestaf- uc befell Alan Musselwhite when. tehnear.ly four hours in rough thermals

till tl e 3F he suffered air sickness and hado and.

i Yet another syndicate aircraft has putS:.~ndappearance in the shape of the e'-l­theInon .Grunau. Its present owners wishalre ~rev'lous ones to know that it hasa n~nr~een up to 5,000 ft. and achieved

r of good flights, one of almost

t~o hours. Everything else apart. it feelsright to have a Grunau on the airfit:ldagain.

BLACKPOOL AND FYLDEOUR absence from these pages has

not been due to a decline. far fromit; we are steadily developing the clubwhich is in sound health. A regula;Newsletter contacts our members fromBlackpool to Burnley. and Lancaster toManchester; we have block member­ships ,from both these universities. Wecannot fly from Blackpool (Squires Gate)any longer. the grass areas have beencovered with obstacles. and commercialoperations leave very few interludes. Wehave settled at Samlesbury airfield all theyear round. thanks to the generous co­operation of British Aircraft Corpora­tion. The number of flying days per yearhas risen steadily. also the proportion ofthermal soaring days. -

Sunday, II th June. was a good ex­ample. one member did both his Bronzeflights within three hours, and our Olym­pia explored 10 miles of sea breeze frontover the M.6 at Preston between 18_30and 19.00 hours. Waves have only beenused on one occasion of east ;wind.although wave clouds appear frequentlyfrom all directions. Regular contactswould surely be made if we could !lainaccess to one of the many promising hillsof Nor~h Lancashire. Pendle, Longridgeand Falrsnape remind yon irresistibly ofPortmoak; we have our scouts out.

Meanwhile. the treadmill turns and sofar this year we have sent off three firstsolos. got three C badges. two Bronzelegs and five Bronze C completed. Oneof. our young men who progressedQu~ck]y ~ solo and C badge has sin<:egamed hiS PPL on an ATC FlyingScholarship. and is now at the Collegeof Air Training, Hamble. We are en­couraged to believe that our hard workhas worthwhile results.

On the ground, improvements areevident by the tarmac floor of the oldhangar and the completion of the steelerection of the new hangar. About one­third of this project is now completed­only 1.700 man hours to go!

It would not be out of place to finishwith a warn.ing to members and visitorsabout the Lyneham Special Rules Zone.This SRZ is a mere 10 miles south-eastof our field. Full particulars of theextent of the Zone and Area. togetherwith procedure. were published in thelast issue of S. & G. Infringemertt of theregulations could severely jeopardise thefuture of our sport.

CORNISH

A T the moment (June) our enthusiastsare digging the foundations for our

new hangar. It was fully intended to havethis complete by now but it seemed totake a long time to decide if we wereeligible for a, grant. Apparently one can­not get a grant unless one has a 28-yearlease and the local authority, much asthey are willing. are unable to grant alease for this period an what is actuallypublicly owned land. However, we aregoing ahead. from our own resources.with a steel framed building clad with

34~

asbestos with sheet steel sliding doors. Ifanyone feels they may benefit from ourexperience they are welcome to dro,p usa line.

The courses are going extremely welland we are enjoying marvellous holidayweather.

In the clubhouse we have yet againre-organised, refurbished and redecoratedthe bar and we have a fortnightly socialevening to look after the profits.

The Blanik and Olympia 419 have.both together with the Swallow and 463.been keeping our mem'bers afloat.

COTSWOLD'OUR Chairman. Roger Bunker, has

. retired to take up the duties ofCFT and the club presented him with aninscribed lighter to show its appreciationof his untiring work on our behalf. If hethinks he is in for a rest cure now.however, he is mistaken. It would be bestto dispel a viscious TumOUr at once a'bQutRoger. He was not chosen as eFI justbecause he has a leather helmet. Seri­ously, though. he brings a unique know­ledge of spinning to tile club. and it wasiust unfortunate that his last attempt wasin a Ford A,nglia.

The new Olympia and Ka-7 are doin~

splendid service. The one having beenchristened "Max" to pair UP ,with "Min"the T-21, and we are thinking of cal1ingthe other "Overdraft" for reasons nottoo difficult to imagine.

COVENTRY

THE weather havin.g suddenly decidedto get more seasQna!>le in the last

few weeks. there has 'been a mad rushof Gold C attempts. and we are pleasedto say that Alwyn Findon's flight in hisDart 15 to Grimsby on a dog-leg viaKidlington, brought him success.

Sunday, 11th June. saw the ,departureof four pilots on Gold distance flightsfor Plymouth, but when most werethinking it was "in the bag" the seabreeze did its worst and all fell shortthis side of goal, the furthest distancebeing achieved .by Rieg Ludgate in theclub's Skylark 4, about 15 miles short.

On 3rd June we were host to theHusbands Bosworth Steam-traction Rally-an annual village fete held this yearfor the first time on a corner of theclub's field, and as the weather was kind,with a very large attendance, we feel thiswas a very successfu.l exercise in publicrelations, which we would like to repeatnext year. Much beer was consumed inthe evening by a private Skylark 4 syndi­cate, who had rigged their aircraft at theRally and had become hoarse in extol­ling the joys of gliding to hoar,ds ofspectators and little boys!

FOl!lr potential instructors were packedofr to the Mynd in June to join in withsome lOCal members there for a week'scourse in instructing.

DERBY AND LANCS

A FURTHER phase in the field im­provement plan is in progress­

trenches, trenches, everywhere-it lookslike the Western Front in 1916. Drainpipes are being Ia-id , anu are beingcovered by a layer 0f stones to givebetter field drainage. After pulling stonesout of the fi'eld for 30 years, we ar.e nowbeginning to stuff a few back in. Revengeis sweet!

On the mechanical side, the Thorny­croft twin-drum is back in action, andthe Bedford twin-drum now seems to bebanging on a1'l six. I,n addition. we areeagerly awaiting the' arrival of the Dop­peltrammel ... Doppeltra ... Dop ...the new German winch!. It boasts fluiddrive. two ·drums, eight pots, and 240rampant gee-gees. We s'hall be able tolaunch the entire fleet-on one cable-simultaneously!

Our fleet is now complete, two Cap­stans. two Swal1ows, a 2B and a 460. Thegrey T-31. No. 1, has been retained. Shewas .the pride of the training fleet only ay·ear ago, but the arrival of a Capstancaused the dust to rest heavily on herwings for a wh;ile. She is ill demandevel'y weekend forioy rides. and is re­garded in awe by the all-Cal'stan post­solo pilots who are now beginning toappear on the Swallow list. The conver­sion phase had its problems. as oneTutor pilot said, "Every time I'm passedout on a ship. it gets sold!" Hangarpacking, too. has had its problems ...

The better weather has brought wi·thit cross-country t1y,ing. Alan -Beckitt,mounted on the Dart l7R, declared andreached Sutton Ban,k on 27th March. viaSheffield and Doncaster. Tom Smith, inthe Skylark 4, went to Sutton Bank also.on 22nd May. SeftoD Hawley com­pleted 80 km. in the Olympia 460 forhis Silver C distance on the recent taskweek for pre-Silver C pilots.

This was held at the end of May and52 launches, 44 hours 36 minutes flyingand six cross-countries were completed.

Page 84: Sailplane & Gliding 1967

In fact. 'anyone wishing for a pleasantweek's flying from 22nd to 26th Maycould not have done better than to cometo the sunny heights of Camphill . . .II's a lot safer than landing in thesesecret Atomic places!

Bar receipts show that a certainamount of drinking has taken placerecen.tly. R. H.

DEVON AND SOMERSET

W E have had our first visitor-ayellow Skylark from Booker-and

it is surprising how this lessened the feel­ing of isolation which sometimes creepsover us out here in the wilds.

Achievements for this period compriseC certificates for Chris Slade and KenJenkins, Bronze for Arthur ClapI' andat last Brian Weare has managed tobreak out of the magic circle boundedby Merryfield on one side and theRampisham masts on the other. Havingreached Cerne Abbas, this, subject toconfirmation, C'Ompletes his Silver C. Hegot his five hours ill the Eagle--ratherlike driv~ng a bus in a car rally! Al­though Pete Slanley shot off to Andover

one sunny d<J.Y. he omitted to carry thatsmall but vital barograph. Mjke Dixonalso got his live hours and Mike Fa·ir·dough height and distance for Silver C.

The ground crews, if trn:y will forgivethe term. have been busy on activifliesranging from cesspits to winch gears andit really takes dedicat·ion to forego thiswonderful soaring weather and stick tl;)tbe earthy jobs. Not.a little credit ~oes tothe Welsh Wizard of lorries and hard­core-Jim Wat]cins.

The Nationals produced a 20th placefor John Fielden of which the club isproud and a little excitement in thematter of his house burning down duringthe competitions-if you can't set theplace alight one way ... ! !

One old friend and ex-club member,Reg Chubb, dropped in 'On 10th Junefrom Tarrant RushlOn in bis beautifulDart 17R. The tenth Commandment was,I am afraid. well and truly broken. Thecaravanserai has grown ama~ngly sincelast writing and the vast improvement .inthe weather has enhanced the attractionsof our new site way beyond our expecta­tions; come and see for yourselves.

A DVERSE weather during the pastfive weekends has cramped flying

at Dumfries, but frustrated membershave founel employmen.t carrying outvarious jobs, such as re-constructing theglider trailer, and repairing Winches. etc.

We were pleased to welc:ome a visitfrom Ray Stafford Alien. who examinedAlex Aswel1 for his Glider InspectionTicket. which has now been granted bythe BGA Technical Committee.

We have also had a visit from BorderTelevision. who made a film at Dumfriesfor. the new outdoor sports progr<\mme.

ESSEX

SINCE our last news in the S. & G.the Essex club has grown in leaDS

and bounds, membership has forgedahead and we are now consider·ing awaiting list for prospective members.

Our fleet consists of a T-21, Ka-7,Swallow and Sky·lark 2. A great deal ofour good fortune can be attributed toour new pulley method of launching;this has Droved to be a real boon; ca,blecosts. which were our largest single ex­penditure. have been cut by well overhalf. the launch rate has been raisedconsiderably and fumbles down to aminimum. this couDled with aerotows(which for the help and assistance fromthe BOA we would not have had) hasinjected a feeling of success that hascarried. us buoyantly through the lonl!:winter months and into what promisesto be our most successful summer seasonyet.

The Skylark, whith is our latest at­ouisition, has been r,eserved for BronzeC pilots and a,bove, this has resulted ina few of our older members who werequite content to just bash around thecircuit fallin.g over themselves to get thenecessary qualifications to fly it. Surpris­ing what a little incentive will do.

The clubhouse, which has been lan­guishing somewhat, has had a long 'Over­due facelift, everybody sloshing emul­sion about with an abandon not seensince tbe formation of the club, and ajolly good job they made of it too, it isnow worthy of anyone who may dropin from a tross-country for a pint and ameal.

GREAT news from the soaring. grounds! A situation which at one

stage looked, as we in the flying gamesay, "dicey~ turned out to be a triumphof man ov,er machine.

Some doubts were expressed about hisqualification as a "solo pilot" in as muchas the T·31 did take-off on a normaltraining spin with a pupil. Bad luck,GeTtie!

Alf tells us that at 4,000 ft in a. cloudthe glider took charge and the sit\lationthat existed was not as Alf expected itto be. With lightning re.actions Alf issuedthe dramatic command "Abandon ship,and stand not on the order of thy going."YOIJ will remember that Alf is a J:)Oet

Grasping ,the ~ituation and the side ofthe cockpj,t, Gertie launched herself intothe dank and misty void. The stage wasnow set. Relieved of Gertie's weight (nonard feelings. Gertie) the glider settl eddown and Alf found himself once moremaster of his fate. Moments later. at10,000 ft .• Alf burst once more trium­phant in.to the blue. Unfortunately, theupper wmdsbeinj( what they turned outto have been, Alf found himself, as hethought, temporarily uncertain of his

posItion. As the altimeter unwound, thetemporarily uncertainty became perma­nent. Again this lightning reaction, Alfrealised that the glider pilot's moment oftruth was nigh-a field landing.

TIle scene, dominated by high tens'ionwires and factory chimneYs. did not deterhim. Summing IJP the situation at aglance, Alf s,wung into' the approach,Unfortunately. the centre of gravitybeing where it. was-no Gertie. remem­ber, and what AIf maintains were "freakmeteorological conditions caused by t.l)ecurl-over from a nearby Chapel of Rest"-the trusty T-31 en,tered the tail spincase (we know our jar,gon). This causeda vertical descent culm.inating in anarrival on a tombstone in the Gardenof Remembrance of Graunchester UrbanDistrict Council Cemetery.

It was upon the wreath placed grate­fully ,by the British Legion lhat verymorning that Alf settled. Nothinltdaunted, Alf left his bird in the ha.nds ofa member of the local const.atbulary whowas lo.oking for his helmet, which hadbeen dislodged by a rotating wingtip.

"I have to find a farmer," said Alf."You'll 'be better off looking for the

gravekeeper," Quipped the BobbY.. Now we come to the Question which

must have been in all your minds. "Howwas it possible to determine the exactheight at which the flight became solo?"

Fortunately for AIr, in her unl're'meditated exit, Gertie 'struck the baro­graph with her foot, leaving a distinctivekink an the trace. Our official observer.Mike Rometer, entered into eOrresl>ond­ence with Roger Barrett, of FlyingCommittee fame.

The period of suspense while theFlying Committee sat was unbearablenot on-Iy for Alf but for all his pupilstoo. FinarJy, the magic letter arrivedagreeing that the height gain fromGertie's left fOOl low point mark indeedhad earned AI! the first leg of thecoveted emblem.

One que.stion remains. Who l'aid forthe flight? Come clean, Alf.

FROM a flying aspect, April and Mayhave not been very exciting: satis­

factory for trainin~ and circuits andbumps. but disappointing for the lack ofgood cross-country da ys.. We had two Silver distance le~s en1st April-Dennis Monckton and RayHallon to Redhill, both in Skylark 4'sand later in the month Ray ,l(ot hisheight. thus completinl<l his Silver C aswell as holding top pOSition on the clubladder. _

The latest feat was Dave Brown'sflight in his Skylark 4 to the Southdowndub at Firle on 10th June. the first timethis had been done from Challock. Howabout someone from Southdown flyingup to us?

May 7th produced what must havebeen a club record-"average time ocrlaunch"-day, with 49~ hours from 46launches. which included two successfulfive hour attempts.

We are proud to publicize tAe factthat our CFI. Roy Hubble. was awardedthe Royal Acro Club Bronze Medal thisyea for his contribution to J(Jidin~ andnone of us at Challock would hesitatein underlininll this.

The Kent Club was well represented atth: Billgin Hill In:emational Air Fairin May. providing both gliders (andpilots) for the double aerotow as well ashelping Slin~sby's and Derek Piggottwith the T-53.

MIDLAND

THE last issue of SAtLPJ.ANE & GLIDINGdid not include any Club News from

the M.G.C. although our winter waveflying was very well reported. Waveactivity is not so prolific as it was earlierin the year but there is still the occa­sional good one.

Recent weeks have seen considerableactivity directed towards site mainten­ance a,nd improvement. The tnliler parkhas been evacuated. levelled and coveredwith hard core which. when the ,iob iscompleted should result in a better air­craft rigging area and much less mudaround the place.

The number of private owner groupson the Mynd has now risen to nine withthe arrival (a few months ago) of aDart 15 Owned by Alan Jones and AlanGriffiths. Thus the tendency to privateownership continues although on nothinglike the scale of some clubs. No doubt,our lack of acro-towing ,is a major factorhere.

The ladder competition has provedpopular. In the National list, as at 31stMarch. 11 M.G.C. pilots were in­cluded in the 41 listed. This strong repre­sentation owed much to the superb waveconditions which we enjoyed earlier inthe year.

Unfortunately we had to cancel ourown competition. but a number of ourmembers have entered competitions else­where.

On a semi-competitive bas'is. NickGaunt flew in ftom Nympsfield tocollect the appropriate collectors tankardfrom our bar and two days later DaveCarson flew down to Nympsfield to gethis Silver distance and to regain thetankard.

W E have been visited recently by anumber of disasters-the loss of

our T-31 on Easter Saturday being theworst. It was left facing into the windwith only one rather lip;ht person on thewinp; tip and nobody in the cockpit. agust of wind got under the raised wins:.snatched the T·31 out of the hands ofthe unfortunate person on the wing tipand threw it over a couple of carsparked nearby. When arrivinp; at thefield shortly after,wards the other p;liderson the field all had one wing into wind.one person in the cockpit. one lying onthe wing tip and one on the tail. whichmust have made a distinct change fromthe usual pastime of glider pilots stand­,ing about talking. I often feel that it is apity that Trappist Monks do not run agliding club and that members of otherclubs could v'isit it to see how remark­ably efficient it was-but I am alwaysconsidered to be a bit anti-social.

The other disasters which haveoccurred have been with our winches.

SEJSiRUP AGAIN CHAMPtoN.-The DanishNational Championships took place

at the Amborg cefltre from 4th to 15thMay, starting with excellent weatherwhich gradually deteriorated. so that thefour last days were unflyable. However,seven valid competit·ions were flown.

For the first time, p1rticipation wasnot free; admitted were the first 15 fromthe rating list, the first 10 from last year'sB-championshios, and up to five moreat the discretion of the Gliding Corn­millee of the Royal Danish Aeroclub.Among these was. for the first time. aforeign guest. Adam Witek from Poland.f1yi,ng a Danish Foka 4 placed at hisdisposal by Aksel Feddersen.

The first da·y. 4th May. a 203-km. Tri­angle was completed by 27 of the 29nilplanes witb Witek and Ib Braes(Foka 3) both winning at a localrecord speed of 74.7 k.p.h. CarstenThomasen (Ka-6) was third. P. V. Fran­zen (SHK) fourth. Leif Corydon(Vasama) fifth and Niels Sejstrup sixth.

Next day's flying along a line towards'Skagen. with a strong easterly head­wind component, was won by Franzen(120 km.), followed by H. Lindhardt(Ka-6) (111 km.), Corydon (110). Witek(108), and Braes (100).

A 114 km. OuHj.nd-Return in theafternoon of 7th M ay was completedonly by Sejstrup (32.1 k.p.h.} and OleDidriksen (l;;,a-(,) (31.8), with Witekthird (88 km,).

With recent publicity in the NationalGeographic magazine. the Readen'Digest and by virtue of the Wait Disneyfilm "The Boy Who Flew With theCondors". shown on national T.V. net­wcrk.s. ther.1) has heen a significant in­creas.e of public interest in soario/!. andan influx of new members. even in ex­cess of the training facilities of mostclubs.

On the past side. the lonll: week-endtype of contest is ever popular here. Twoclubs held such on the Victoria Daylong week-end (20th to 22nd May). andbeth report as good turnout as could beexpected. The Q:ttcr supported one wasthat held by the Cu-Nim Gliding Club ofCalgary, Alberta. with an entry Ust ofnearly 20' sail'planes-very good for a1001 rhree-day contest.

Witek went downshortly after tbe first turning-pOint. whileBraes thought it to be a speed event.turned back to Amborg. landed, lunchedand took o.ff again to discover that it wasa. question of keeping flying.

On 9th May two completed a 309-km..speed event on a broken leg leading107 km. to the SOllth (Roedekno). then202 km. to the north to Borup glidingsite.. A head wind component 0)1 the firstleg (which only counted for about 225of the possible 1,000 points) meant thatmore time was spent om this. than onthe rest. Joergen Lauritzen (Ka-·6E) wonwith 40.7 k.p.h. and Lindhardt had 40.3.while Ejvimd Nielsen was third with306 km. Several pilots struggled formore than eight hours.

All went down near the first turning­point of .tbe lOO-km. Triangle OD 10thMay, when weather suddenly collapsed.Late in the afterno:on things improved;UP to 1,700 melres cloud base was fo undnear Arnborg, from which it was pos­sible to gl ide past the first and secondturning-points. The glide ratio of theSHK meant v.ictory (628 points) to Fran­zel1, for 74 km., followed by SkovgardSorense.n (Vasama) (72 km) and KjeIdDahl (Ka-8) (71 km.). SejstruD was 8tbbut still in the lead with 4,530 points,foilIowed by Franzen with 4,19.3 andEjvind Nielsen 4,022.

Fighting ,in dry therrnals on 11 th Maytoward Boru.~, many pilots went intoKarup control zone, while those whotried to keep out had to land. Only afew succeeded in evading it and tocontinue. As there had been severalwarnings from ATC the preceding days,it was found necessary to do' something.and a dozen pilots who next day ad­mitted to have been in the ,control zonewere disqualified, with the result thatthe few innocent pilots with some resultonly got a few points, Skovgard Sorensenwinning with 87 km. and 214 points.

Another good day was badly wantedto forget this day, but did not come. So,Sejstrup won, as in 1959, 1961, 1963 and1965. This time, however, with a muchlesser margin than the more tban 2,000points in 1965.

Witek, who had not. flown in Denmark

before the contest, was SULP -j~ by theweak and variable conditions and saidhe learned a lot -and would go back andtell about the, special conditions. He per­formed the longest flight in his 3.500hours' gliding career with a 7 hr. 55 min.flight resulting jn 251 km.

On the Whole, the five Fobs partici­pating had a difficult time, while the fourVasamas did something better and themany Ka-6's even better. The SHKproved very suited in all kinds ofweather. Unfortunately the five Pir~ts

ordered by Danish clubs did not come intime to be compared with other types atthis event.

PAKISTAN

SOARING in Pakistan was started byCcl. and Mrs. Mikulski. who came

to P'akistan from Poland .. They demon­strated soaring in Karachi in 1952. andthe Pakistan Air Force made glidin~part of their training programme - atleast for a few years.

Mr. MinoD Marker brought a SlingsbvT-2l Sedbergh to his home town Que.ttain 1956 and learned to fly on this ship.In 1961 he founded the Quetta Soaringand Flying Club, and since Ihat timeabout 120 soarirrg pilots have beentrained in Quelta. The spacious hangarwas also largely built by Mr. Marker.and in it I saw a new Slingsby Capstantwo.-seater, two Slingsby T-21 two­seaters, two Olympia 2B single-seatersand one Grunau aaby. They were com­fortably spaced; leaving room for addi,­tion of future equipment.

The launching method is winch tow.done with a Pfeitfer winch, imp:Jrtedfrom West Germany. Unfortunately, notow plane is available.. The 1,5OO-fl. run­way permits winch tows to about 500 ft.maximum and due to Quetta's powerfulthermal activities many flights of longerduration have been made after winchlaunches_ Several times pilots haveSUCceeded in getting into wave up'currents, reaching altitudes up to 23,950fL (7,300 m.).

Mr. S. M. Mumtaz, formerly of thePakistan Air Force. is fully employed as

364

Chief Flight Instructor and has accumu­lated more 'Ihan 2,000- hours in sail­planes. One of his students. Derrick P.Middlecoat, was the one who flew anOlympia 2B to the highest wave altitudehitherto reached in the Quetta area. If atow plane was available, the number ofwave flights would greatly incr,ease, sincelenticularis clouds are a cQmmon sight inQuetta's sky.

When I visited the QueHa site, waveclouds were standing all over the sky.The date was 8th April, 1967. But. dueto a Government regulation dating fromthe Pakistan-India war of September.1965, I, as a foreign national, was notpermitted to fly, which really was a pity.The wave clouds were clas3ic and theelub ships were equipped with oxygen.Efforts are being made to abolish thisrule, which at present \)rohiboils sportingflights by foreign nationals in Pakistan.It ap~ears c:ol'1tradictory in a countrywhich makes efforts to attract foreigntourist>. The Quetta site would be wellworth visiting' fr,om a soaring pilot'spoint of view. The ciimate is always verydry. so that summer temperatures risingto 128' F. do npt feel as bad as theysound. Tbe t.hermals are terrific. thecloudbase very high and wave cloudsappear very. very freQ uently. If Qu.ettawere located in the United States. itwould be .a Mecca for soaring peop~e.

The friendly spirit of the Quetta soar­ing fraternity was vividly illustrated by

. the faces look.ing at me with the sameyouthful enthusiasm, when in the evefl­ing at tea time we all sat round a tablein rhe Lourdes. Hotel at Ouetta. To myleft was the turbaned head of a youngstudent who prepared himself for theMullah calling' in Pakistan's state'rel;igion. Even tho.ugh he had. little under­standing of English, his eyes never losttheir enthusiastic expression, and helaughed with his pals whenever theylaughed at some part of my story. Therewas the eager face of Derrick Middle­coat, a Christian Anglo-Pakistani. andright next to him the handsome face ofChief Plight Instructor S. M. MUlTltaz,wh(} again was a follower of Pakistan'Sstate religion. All these young men withlove of soaring in their hearts were look­ing up to Minoo Marker. their soarini\friend and sponsor, who belongs to theParsee Community. I can only wish that

EDITORI"L NOTE. - Peter Riedel wasamong the German soaring pioneers ofthe early 1920's. and obtained the world'sseventh Silver C in 1932. He has spentmany years in Canad.a, and we last sawhim in Argentina at the 1963 WorldChampionships. He is now with PanAmerican World Airways at Karachi.

RHODESIA (Gwelo)HAVI~G seen an .the news from .the

variOUs clubs ID your magazine,the Commillee have nominated me tobring you up to date with the (gliding)happenings in this part of the world.Perhaps I could give you a very briefhistory to start with:-

Our club, the Midlands Gliding Club,Gwelo, Rhodesia, was formed inJanuary, 1958. A pranged T-31 wasbought from Umtali Gliding Club, re­buIlt and flown for the first time inJune.. 1960. This T-3.1 is still doingsterling (sic!) service, having. during itsCareer with us, bad three major prangs.

Other aircraft in the club have in­~IU<led a Kirby Cadet (donated to M.G.C.

Y Selukwe on, amalgamation in 1962ancl written off in a prang in February,~?4) and a Wolf (bought from Salisbury

l!dmg Club in March, 1964, and alsoWfltten off in a prang in October. 1964).h Currently ~ying and in g~ocl tl'im we

ave a Spahnger-I g of SWISS manufac­~ure of about 1939 or 1946 vintage. ThjsIS a gull-wing medium-performanceSachme. bought from the Johannesbur~lz~mg Centre, ~atagw:anath. in August,

, ,complete with trailer.

Finally, the pride of place in theclub's fleet is our Skylark 38. Since itspurchase, complete with all blind-flyinginstruments, oxygen and trailer inNovember, 1964, it has ,earned numerousawards and QuaJificatiens. Some of theseinclude nine Silver COs. five Gold C's andfive Diamond goals. Our current mem­bership stands, incidentally, at 15, and allthe machines are club owned. Specialmention must be made of our youngestflying member, Mark Penberthy. whoturned 16 years in March, 1967. Markgained his Silver C in December. 1966.and completed his qlla!·ifying number ofhours to fly the Skylark on his birthdayin Mareh.

Our site is some 3~ miles from Gweloon a disused ex-R.A.F. aerodrome, com­p~ete with clubhouse, workshop andhangar. The main runway has beenextended .to a length of about a mile_

A recent innovation has been thefitting of one-watt V.H.F.. radios into theSkylark and S-18. These, together withthe set working on the ground. keepeveryone in touch with what is happen­ing in and around the field. It ,is quite aregular thing, too, to. chat with theSalisbury Club pilots whenever they areai~bQrne some 200 miles away. Ourclub altitude record is currently held byBarry Tur-ner who flew to 17,000 ft. inbecember in the Skylark. Barry unfor­tun:ately missed his Diamond height byonly sOO ft. This was due to him havingto abandon the attempt when he en­countered severe icing conditions. Thebrakes iced up, and this restricted anyfurther flying in the cloud.

We are waiting for the onset ,of ourhot season (August to November) at themoment. The Limited Class competitions(machines with a glide angle of up toI in 27) are scheduled to take place inthe first two weeks of October, After thiswe are hoping to collect remainingDiamonds with 500-km_ flights to theBotswana border (Plumtree) and back.Perl1aps even a few Diamond heightgains may be obtained also. We wouldbe pleased to hear from any other clubsin the world who have T.V. brakes kingprohlems during gain of height attempts.This bogey has been a real problem andlooks like being quite an obstacle if wedon't get some satisfactory solution toprevent it.

W-E are nearly into the middle of ourwinter and the thennals are still

bubbling. In fact, on one Sunday recentlyat 5 p.. m. three sailplanes were at 6,500ft. playing around just under c1oudbase!So you can gather that ma.ny hours ofsoaring have been accumulated by thekeener types. With clouds still around.cloud-flying Jjractice has been done onmany days by many pilots. Cross­country flying has been somewhat limitedby the fact that landing fields sti.\l havebumper crops in them, or that they arecovered in long grass which is mostly~JVer six feet in height!

It is more than evident after sixmonths' operation that we have an ex­tremely valuable asset in the PiperCruiser fBlanik combination. The Cruiser.which replaced the. Tiger Moth, basnever looked back. for we have quickert0WS. less fuel ,is used, maintenance isdown and therefore utilisatiol'l is higherwith subsequent benefits to the cluP. Allthis helpS to keep each tow to 1.500 ft.at 1Os.. Is this possibly the cheapest On­subsidised aerofow rate in tbe world?

The Austria of John Saunders is backafter its tussle with a ploughed fieldduring last year's Nationals. It isffyingas well as ever. We regret to report thatthe Bergfalke is in hospital. and it willbe some time before she has fuilyrecovered! She wasn't looking where shewas going one evening when her wing­tip clobbered some long grass.

The. whole airstrip is having a face­lift. Widening of the runway and exten­sions to the undershoot and overshootareas are well in hand, the object beingto make landing and taking off muchmore comfortable with the peace of mind
