Finlc:)y gave Licher all the recent mai.l and merribership applications he had not been able to process. Licher said he would process them while Finley got·the financial records updated before turning them over to the new Treasurer. ;_ r~solution was voted to establish a new bank account after the new Treasurer is electedo Thef~ followed-an extended discussion concerning the problem of flying sites. The current situation regarding oach of those used now and in the past was reviewed, including the beaches at Playa del Hey and Torrance, and hill~ at Norco and Palmdale. Other possibilities were discussed, including a bowl near Hemet~ flood control dams and the Topanga area. Each will be explored further in an attempt to select a suitable site for the Turkey Fly, which it was decided would be 2n informal Meet for .fun flying, rather than a competition, as such. The meeting concluded with a discussion. about SCHGA. 9 s future, its scope of effectiveness, the need for more in;_ structive programs at the meetings, and more help in producing GROUND· SKIMMER issues o Afterwards, Gary's nearly completed 11 TW!," monoplane hang glider was examined in his garage and first flight date set as Sunday, October 15th at the beach. o

Tom reported on his research of mailing rates, with conclusion that GROUNTl.SKIMMERs would have to be sent via third-class mail, although a bulk mailing permit would be obtaine~ for 1973 to minimize mailing costs. The new bank account had not en opened yet but Kocsis said he would get the signature card that week.

Notes from the previous meeting were read, which led into an extensive 6iscussion of possible Meets es. Dams had been checked out and most other prospects mentioned at last meeting and found to be unsuitable.

I started construction of the fu11-s.i zed vrinp on l!ov. 3, 1971, and took it out to 11 fly 11 for the first time at the C'reat Leap Year Party at Play a Del Rey in ,Tan. 19 7 2.

I c1:i.c1n I t pct off the rround that clay or on P1any days after that because as it turned out: my position was too far forHard and also I didn't have enonrh tip reflex to maJ:e the winr fly at the proper C.G. location.

After these problems were taken care of I finally flew some very short flir:hts in April.

The flichts in April demonstrated that the winr; had a r:ood rlic1e ratio and a low sink rate.

Hov1ever, I f 011:nd out very ciu icl:ly that my directional controls ( 1. 6 sq, ft. dra 1,; plates) Hould not turn the craft. \!orkinr.; out control probleJ;lS plu:::, some other chan,>1:es took up the rest of the time up to and includinp the !fontr,ornery Meet in Anr:ust. I now had control surf aces bip; enour:h ( 6 ::;q. ft.) to turn the craft but my control cable system was very noor.

My bip moment was just after the lleet closed v~1cn Taras Kiceniuk, Jr. flew my winr: for its first lonr ~li~es down the contest slope.

The r,lide was very rood anc1 I couJ.d see that ~y efforts were ~erinninr: to pay off.

However, Taras co1tldn 1 t operate the directional controls because of the poor cahle system so I still had work to do.

I chanr;ed the cable syr,tern on La1'cr Dav and l'att and I took the winp; out to a small slope on Sept. 10th. !z,tt 1 a:::; ver~' anxious to try the winr.; so I let hiJY1 have the first fli,ri;ht.

He lannctied from a noint 2/3 up the ~ill because of a road eJ:1 1 iank~ent across the end of the field at the bottom.

Beca11se of the ,1>000 11:lioe we needed plenty of landinr: room at the bottom.

Fe took a fev steps into an 8-mph vind and flev7 out from the hill, climL,inrr in p:11c,ts anc1 over-controllinr; in pitch because he is ttseci to a Rorallo,· but he ~ade a (Tooci, no-run landinr:.

He now became determined to spend t~e afternoon learninr: to fly the v1inr.;.

He learned to handle pitch contra] soon but learning to operate the directional controls came slower. l 1 ith the new cable system the controls operated easily and Pe founcl novr that the surf aces were too bir;.

The control movements have to be so small that it is hard not to over control in a turn so I plan to remove a feF inches from the surfaces.

THE 1ST SMOKEY-THE-BEAR Hil.NG GLIDER EXPEDITION

By W.A .Allen

(Author's note: The following article relates the oddessy of a small group of experienced and prepared Rogallo pilots who sought to explore the possibilities of realizing every child I s dream, to le:ip from a mountain and to soar freely over the rocks, trees and meadows. The reality of it was that these pilots and all others like them are pioneers in an unexplored area of aerodynamics and meteorology, and there are dangers-dangers to be f:wed with ail possible caution, but dangers nevertheless. One of the group, Ed Gardia, was ki..lled after crashing due to unknown reasons (see accompanying accident report) while flying at Slide Mountain near Lake Tahoe in Nevada. No one was enjoying the tri-p more than Eddie, and I'm sure that he would want you to hear about the adventure in the spirit that we experienced it.

"That I s cool, man, 11 he would have said with a big smile.)

The plan was to meet at Dave Kilbourne is house in Palo Al to, California, on Saturday, 23 September 1972. Ji. small group of Rogallo fliers had set aside their vacations with visions of spending the following week leaping from various California geographical high points, and careful preparations and practice flights were scheduled for the weekend. Dick Eipper, Ed Gan.ii.a and Dave Muehl rolled in early Saturday after an all-night drive from L.A., while locals Jerry O'Connell, Dennis Smith and Rich Kilbourne (brother of Dave) arrived in the aftornoon. Carl Boenish with movie crewman Dick Meistre, and Ted Webster wii,h wife Geta arrived from the southland that night.

1

iihen the writer arrived Saturday afternoon, there were several kites set up in Kilbourne ts) back yard, where all cables, key rivets and bolts were being replaced.

Some were also receiving a rather strange-looking modification-two large, spoked bicycle wheels attached to the ends of the control bar. The wheels have several purposes: to use for transporting the gliders on the ground by pulling rather than carrying, to protect hands in case of bad landings, and to allow wheel landings in the prone pilot configuration instead of foot landings if desired, such as in tricky downwind situations. "\i,ii th the exception of 'i'ed Vv ebster who had a Bennett Del ta Kite, all the pilots present had prone flying harnesses, although Carl Boenish was favoring his more familiar swing seat and Donnita Holland was just learning to use a harness.

One of the strangest sights of the day was that of Dave K~lbourne hanging in his harness from a kite held level for him whilc-:i he swung freely, hands and feet in the air. This helped check out proper rigg:i..ng and was possible because of a new EipperF'ormance prone harness with shoulder restrainers preventing the body from pitching down when the pilot lets go of the control bar, \Vi th this Bill Moyes-inspired arrangement, proper rigging and a rope foot 11 stirrup" attached to the harness, the pilots reported the prone pm;i tion to be more comfortable, especially for longer flights, and to permit flight with one hand free.

Sunday morning preparations were still underway before and after breakfast, and it was around noon that we joined an R/C glider contest ( shades of Playa del Rey!) at the Kilbourne training and testing site. This is at Coyote Hills park on the southeast end of San Francisco Bay. Here the prevailing wind blows straight up a natural bowl formed by some low and gentle but respectable hills, A good time was had by all during the succAesful session, even if Carl Boenish 1 s mental mutterings about his new control bar could almost be heard out loud. Both Dave Muehl and Dave Kilbourne had some short soaring flights. And Dick Eipper I s new 14!-ft. ( 17-ft. leading edge) version of the Kilbourne cy·lindrical Hogallo ( curved leading edge) showed itself to be quite airworthy. Donnita, probably the most experienced female Rogal.lo pilot in the country, had some very nice flights-the first in her colorful

new kite and her first with a prane harness.

A happy 'group· of kite fliers returned to ·Kilbourne 's for last-minute changes; and it wasn I t until after dark that we hit the road f o:r:, the . drive to Big Sur, south of Monterey. Some stayed in motels that night and some of us camped in a park where we combined kites and people the next morning into a minimum number of vehicles. V:Je then drove as close as possible on a back road to ·a piece of geography called "Cone Peak," which _overlooks the Big Sur coastline.

I

J.

At the 'trail he'ad for the fire lookout on top, everyone shouldered kites or .'either · equipment and walked past a sign reading, 11 Cone Peak 2 mi. 11 Carl Boenishha,d pro.2. ·, vided the fliers with skydiver wrist altimeters, and these showed that it wou:).d .. be a 1,3oo~ft. climb to the top. It was more of a walk than any one of us had anticipated, lasting almost three hours. We came to regret that we had not eaten breakfast and that We did not carry tvater or food with us •. (A lesson here: When .t;lying, bring munchies 'and water for both comfort and safety •. Dehydration and hypoglycemia (glucose starvation) can impair mental and physical abilities.)

Two pairs of pilots teamed up and carrie&. the end of a kite on each ·shoulder, while Tedjfe1;,ster and Dennis Smith helped Dick. E:ipper, who is still suffering the effects of his'leg break from a crash ec1.rly in the, year. Donnita Holland ap'pearecf to be · emulating women I s lib as she· carried her kite solo up the entire grueling walk · balanced on her shoulder, but in reality she had an easier load with her new kite's light-weight construction than if she had been walking "porter style" with Dave Kilbourne (who also carfied his alone) and his heavier kite. The wheel idea was and is a good one/but it doesn't work on narrow trails such as we had at Cone Peak. '

r

Somehow we managed it to the top. Some j"4s,t kept going wii;,h short rests and some stopped, and took naps. Ed Gardia and Dave Muehl trailed behind and every now and the,n ·we, would hear a distant shout of "Have • • , you • • . re.ached • • • the • • • top • • • yet?! 11 Dave later commented that we should change the cardinal rule of hang gl:i,ding to "Don I t fly higher than you care to climb. 11 There is a fire lookout on top of Cone Peak and the first of the group to the-top to.ld the ranger there that we were up. for pictures. He greeted all of us ori a first~naine basis, offered us some. very welcome.ct water, and showed us his beautiful colitfotion of telephoto pictures of sunsets, birds, lovers and other animals that he had taken during his many summers on the peak.

After quietly watching several long, thin bags and more peorle arriving at the' -top in one's and. two I s, curiosity finally got the better of "Phil the Hanger, 11 and he asked what it was we had there. life had feared a hassle as is common with officialdom befuddled by peonle who announce intentions to jump off a ~ill. Carl Boenish broke the news and we were happy to see the reaction: Phil got <.n~t his camera and looked for the best place to take pictures. Soon after he asked Ed Gardia where to stand for the best view and J~d later told us, "I looked dowri. There was a kit.e right in front of him. And he had that stoked look on his face that he didn't want to, miss nothin 1 • He hadn't ever seen anything like this in his who-o-ole life."

No really good take-off spots had been found on the way up, and it was only after considerable thought was given to all the possibilities that it was decided to clear a rocky area on the coastal side of the peak. It wasn· 1 t the best place for getting up a good run, but there was room enough, and below the jumping point there was a landing spot in case the take off was not successful.

The pilots in the group were all agreed that after "that walk," there was only one way to get back down the mountain and it wa.sn I t on foot! But everyone sort of looked at each other to decide who was going first. Rich Kilbourne'·and Jerry O'Connell· had led the way up the mountain and so it was that they led the way down.

Like the others who attempted flights from Cone l'eak, Rich and. Jerry had had over SOO flights apiece, many from over 1,000 ft. above the ground and many involving less-than-'ideal wind conditions. Jerry has been flying Rogallos since the late r 60 's and had done some boat-towed flights for hire •. Rich is partner with his brother; Dave, in Kilbourne Sport Special ties which puts out the "J<~ilbo Kite, 11 a regular 80° Rogallo built to aircraft standards.

Rich·took off first and he set the example for the others with his hard run and headfirst plunge off the rocks, di vin.g to develop flying speed and. controlabili ty. The lack of.wind on this cloudless day reduced complications-such as turbulence and drift-inherent to inland hang gliding, but it.also necessitated an extra effort to' get up fiying speed.

As he easily cleared the.spot for aborting take-offs, Rich found himself 5,ooo,rt. above his landing point, a patch of beach he had never seen but knew was there, 3~ miles ::and about 8 minutes away. Al though there were lower hills between Cone Peak and the waterline, everyone was happy to fi~d that the flig~t path was high enough to clear them easily. · Rich had things well under control and had almost reached the coast when Jerry O'Connell made'his launch.· His kite whistled away from u.s, ahd we watched both of them fly aiong a ridge near the water before they went in to lahd on the beach~ Their arrival · astonished a few people who had been quietly sunbat.hing. · The next night as ·we sat at a table listening to the wind blow through trees in a desert campgrouridwh'.ile,coyotes howled nearby, Rich and Jerry shared the experience with . th'osi; \:,f' us whb had had .to walk back. down the mountain. Asked for his' impressions, .Rich responded: 11 Nothing finer.

I was a little bit nervous. out basic ally I was calm. I just ran like hell 'cause I wanted to get off it. And it was ju.st beautiful. The air was calm and I had just never had that perspective. I wanted to do that since I was a little kid, just to climb up the top of a mountain and then go off it. - I just hate walking; down something because there's all this energy; you know, and it's used in stopping you from really going down. I looked out; I just looked around me as I was flying and I could see all directions and I said, 1 This is the finest thing I 1 ve ever done.' The thing that I really look forward to again is having some altitude to use up, like on the end of this. I was debat\ng,, 'Am I going south on the Coast, Highway or_landing there [on the be~ch7?' and I decided, 'Well, I can't make .the campground /where the extra cars were7 tor sure •. ' I just made a really gentle curve, just a steady arc the whole way,-swung out over the' ocean and then came right back in." A look at the ocean showed a: flat, caim surface, so Rich assumed that the wind was negligible. nr just skimmed right over the surf and landed like 10 ft. up on the beach from where the surf was. It was a good landing, you ·know. I landed right on my feet, and I felt just so good. 11 Rich was the first to land, trailed by ,Jerry. "I just looked up and I said, 'Wow, what is that, nian?' I was so spaced on the whole thing tha;t I ·couldn't even figure· who.might 1:>e behind me." tr,:

About :t~e running, head-long dive off the rocks, Jerry conunented~ ·11Vife - just wanted to gain a little speed. We didn't have. to. I came off that hill so easy<. ~.• I got half w&y down {the mourttaiEY an9l, I just. started laughing... First I.·· statited giggling, kinda 'hee-hee-hee, ' and then '.ho-ho-ho-ho! "' .

Donnita Holland was third to try a launch, and she or>ted for the landing. area immediately below the take off point, stalling in. r,:veryone gulped and with di.Cficul ty looked to :,ee how she was. L'.verything was OE c:l.nd after consultation with Dave l\ilbourne .about v,hat .went wro~1g, she prepared to launch again~ r.Once more she stalled in and this time damagc,d the kite and receivec;l. what we thought was a sprai11ed ~vrist. (It L1ter developed that she had brok,:1n her arm, b1~t despite this she ..h~~ped to carry a kite back dmm ~he mountain.)

Dick Eipµer I s turn came up and he found that he could not .run fast enough on the rocks with his bum leg in the no-wind si tua i:,ion. Despite a beautiful-looking launch with his ifogallo rigged cylindrically, he realized tha.t he was not going to get aw.c/-y safely anc,l . <;1.borted. He wisely chose .not to risk another t,:r;y.

Thus it was that two launches had succeeded and two had not when Dave Kilbourne took a deep breath and began his run. He had not brought along tlie cross bar spacers needed to l}elp bow the leading edge~; of' his ll.ogallo, so he flew it in the conical conffguration. This demonstrated the flexibility of Dave 1 s design and did not • . hinder .his performance. The birdlike Kilbourne not only got off and awaY, success!fully, .but showed the ease of flying with the new E-FSS prone harness by waving to us with one hand as he flew with.the other, Ho landed about ten minutes later on a. bridge on the Pacific Coast Highway jti..st above the beach where the others lande·d.

It is presumed that he surprised the motorist who came along at that moment, but we will never know as. Dave reported that the car just kept on going (perhaps a bi.t faster with a more sober driver·;:).

Dave Muehl has a way of leaping suddenly into flight, sometimes surprising photographers waiting to capture that transition from mundane human existence. Carl Boenish with his movie camera and.I with my camera were perched.at the edge of the clearing of last resort as Dave seemingly took wing instantly, passing directly over our heads with red scarf flying and mouth open in concentration.

Carl is still discovering the world that most people lose sigh~ ef upon becoming sophisticated, 1)JlimpressionE.ble adults, and he doesn't usually bother himself with trying to communicate verbally about it except in varying the emphasis which he gives to his alL-purpose word, "wow. 11 11 \;J ow! " he exclaimed like an overawed kid, watching Dave Muehl head for the coast,--"That 1 s the most beautiful thing I ever saw. 11 This might have been a bit rash as Carl has seen his share of. beauty, parachuting vii th hi·s cameras over some pret.ty exciting places. But it certainly qualified for his. top 10 list.

We could hear Dave I s sail flapning almost all the 1Nay to the coast as he held a constant dive to insure control over his Hl-ft. I<'lexi-Flier, somewhat larger> than is desirable for his ll.i5-lb. weight when flying inland.

However, "The best part was breaking out ov,er the watel•" · Ouite a switch for someone wit.h hundreds of launches at Playa del_Rey where training flights are always toward smd never to the water's edge. Dave headed out over the ocean, and noted that his wrist altimeter showed 1,800 ft. at this point. He used some of it up by doing the first 360° turn in his flying experience and then headed back for shore to land, tho last to fly that day.

The pilots had carried their basic tools and slip covers tied to themselves or to the gliders, along with a pair of binoculars and a camera. Once at the bottom, they

derigged their kites, walked back to where the extra cars had been left, purchased some food from a small store nearby, and then met us as the ground party was starting the drive back down the mountain. He lJad finally picked up and walked out just .. before sunset~ Phil the Ranger had undoubtedly had a memorable day. As he was saying good-by to us, hew.as interrupted by his phone and he answered, "Yep, they came from up here.

Yep. I'll have to call you back. You 11.L never believe this!" None of us will forget that day, watching frail humans jump off a mountain and quickly dwindle in size, shrinking to insignificance against the blue sky, against the ocean reflecting the afternoon sun and agaJnst the moody Big Sur coast with its rugged hills and cliffs and its pounding surf.

A thoroughly tired and hungry but quite elated group of people descended sweaty and unshaven on the last restaurant open that night in the little tourist town of San Simeon. We stayed in a motel there and the next day wo split up, planning to meet · at sunset in Death Valley.

Dave Mueh]. and I divided the long drive in my car and it was not until after dark, clear on the other side of California, that we happened upon two trucks parked alongside the road. A strong stereo cartridge unit was introducing all of Death Valley to Bobby Dylan Rnd a Coleman lantern lit up a huge salad Rich Kilbourne was concocting. A ranger in a patrol car soon joined the party, gruffly but with humor asking, 1"JVhat have we got here, boys?" We respectfully turned Bobby Dylan down and he politely didn't inquire~to the contents of all the long bags on top of our vehicles. Vfo explained that we had thought this corner of the desert to be as good as any to eat supper, and he in turn explained how to find the nearest campground and the.n, left.

We fell asle€:lJJ. that very warm night listening to the wind and wondering if it would prevent the planned jump from Dante's View·early in the morning.

The whole group was rejoii.ed early the next day at Dante's View where a fantastic vista of .most of Death Valley can be enjoyed. A few changes had taken p1a,ce·in the previous 24 hours. Donni ta Holland had a small cast on her arm and Ted arid' Geta Webster had traded in their late moael car for a new 4-wheel drive truck in Bakersfield.· The pretty Donni.ta commented on her cast, "My arm really hurt, you know, but I was .told it was OK. 1 think 1 'm going to start being a girl. and cry."

VVhile the group went to the top, I went to the planned landing spot, Bad Water, which is the lowest point in the nation (2tlO ft. below sea level and 5,755 ft. below Dante's View). I set up my camera equipment, put out a ponnant to indicate wind conditions for the pilots, double-checked ev.erything and searched the steep cliffs trying to determine from whence l was most likely to first sight a- speck of humanity supported by a tiny triangle' of dacron.

Dick Eipper had said, "Give us an honr,rr and orecisely an hour later I knew that·r could no longer· hold hack a problem that travelers have had for all time. . I calmly but quickly retired to a little fiberglass hut placed conveniently across the road.

Everything but the flights came to pass, however, and a couple hours later the whole cnJ1"1 appeared at Ijad viater by road with all equipment loaded on their cars. It seems that the r.oad to lJante I s Viev; was clot,ed for repc,l.ir3-, and the ranger:, were hard pressed to find a rule forbidding hang gliding ( they .tried 11 unusual use of a National Park"), but they could threatsn to give citations for using a· closed road.

A slightly rebellious road crew (they had gone on strike recently because it was too hot) had been quite cooperative about letting our group fly. The workers had seen Biil Bennett's film on TV about his surreptitious ju.rap from Di1nto 1 s View, and they weren 1 t about to miss the show this time. But park rangers appeared and none of thew. 'were going to tnke re,3ponsiLility for letting someone jump off their mountain.

A n~gotiating committeo including 1ed 1,,ebstor and Rich Kilbourne v1ent down to talk witt the Park Superintendent, who was a sailplim9 pilot, they discovered, but the coµclusion v.ras a friendly threat ·ove;r the closed road issue. It was a great pow-wow and the Superintendent even cried on the "conmittee's" collective shoulder about jet fighter pilots who like to be <1ble to brng .about breaking the sound barrier below sea level. He hndn't been able to catch any of thon and the practice was upsetting the tourists.

Apparent],.y we had been uqder surveillance by. the rangers since vre entereq ,tiv,B _.park.

When we considered it, r,ix cars travelling together, five of which were carrying suspicious long bundl@s, several of whic.h ..borf3 bumpe;r stickers declaring, "Go Fly a KitE~," and most of which were b,.:;ing driven by long-haired; boarded characters, it really wasn't too cool a r.1anner in which to enter D&,ath Val~ey a week and a half after Bill Bennett had done his thing on the 11 Thrill Seakers 11 TV program. At ·lunch we resolved to nane the trip, "The 1st Smokey-the-Bear Hang Glider Expedition, 11 Rich Kilbourne's idea to remind everyone in tho future to be on guard for national park bureaucracy. Then we all went and taped over our bumper stickers. Later developments showed that this move got us nowhere as the r,mgers were still able to spot us •.

In the af.ternoon we went up to a place called ffah()gany Flat on Death Valley's _west side. Vie all piled into the g:r:oup 's two 4-wheel dri \'.'C trucks and soon found ourselves being chased by a ranger 4-w!1eel drive truck up a steep, narrow, gravel road.

At the end of the road we jumped yelling from the trucks and split up into the trees.

Calming down, we surveyed a possible launching spot, decided against it an~ returned to the parking area. , We we:re. feeling pretty acetic .and comments were being r:1ade like a suggested Boraxo soap commercial with a Rogallo about to lnunch in to Dea th Valley when a ranger appears and stops the flight by yelling, 11No t,oapP At this point the ranger who had followed us came over ·and introduced himself -with, '1I hate to spoil your sweet sense of' persecution, but 1 1m not here to stop you, only to watch to see what you are up to." It turned into a great discussion and somehovr we ended up talking a.bout.how to preserve Big Horn Sheep and some kind of rare pine tree. (

Of course, we in the back of' our minds. had. appreciated the ran;gers 1 pqint of view about their responsibilities and about their not understanding what we were trying to do. But it wasn 1 t until then at fahognny Flat that we would adr.1:i. t :i. t, and the group decided to move ,on to morn friendly territory.

For me the expedition ended that nL;ht at. the little town of' Independence on U.s.

395. After supper the group headed northward to Slide Mountain near Lake Tahoe, where.the odde$BY finished the next day on a note of tragedy as will be written-up elsewhere. I headed southward to home in Culver City, temporarily delayed by a water pump failure. I was barely able to purchase a new pump which I installed . , myself. And so it was that I arrived home, after 1,580 mile,3, with two gallons of gB.s and 68¢ in my pocket.

WHAT HAPPENED AT SLIDE MOUNTAIN (An unofficial accident sunn:nary and memoriam to Eci Crardia)

By V·J ~A .Allen

We all lost a good friend and active fellow hm1g glider pilot with the first known fatal accident in modern foot-launched h,:mg gliding. On 28 September 1972, .Ed Gardia, age 22, the manager of Lynwood 1 s olympic swimming pool, and an enthusiastic Rogallo pilot, was killed while flying at Slide Mountain nec=tr Lake Tahoe. He was a member of a small group of pilots explorinp: new places to fly during a week-long expedition around CR.lif ornia. Al though the .group's members would te 11 you that they we.re out just to have some good fli?;hts, in reality they were pioneering new flight paths, and they together had the experience and well-prepc1.red equipment to do it.

I had left the expedition the day hefore, so most of the following comes from exten-

sive. conversations with Dick J~ipper and Dave Muehl. The group had stopped at Mammoth Hot Springs the night before, and everyone soaked in the springs and slept late that morning. For breakfast, Rich Kilbourne fed the group a huge omelet he had cooked in the bad: of Jerry 0 1Connell 1s camper while on the road. There ha~'t been any alcohol or anything else passed around, and in all respects there is. no reason to believe that Ed I s mental or physical capahili ties were somehow impaired that day.

Dick Eipper de scribes the lc=tunches from the 3, OOO~ft. slope: 11We · were taking off from a level., smooth, graded parking lot. The drop was good. I would sa;y: that out of all .the flights, Ed had the best launch. ThP-re ~Rd been six flights Lanrf/ I was the last kite scheduled to go off, and the ranger /standing nearby with binoculars7 said. 'Hey, one of your men just hit a tree. 111 Dick looked through the binoculars and could see no movement. The crash scene was reached at about 45 minutes after the accident and there was nothing to be done. }}ddie may or may not h;:i.ve brushed a tree he should have been ahle to fly around on top of a ridge he was flying over. Something, possibly turbulence caused by the ridge, made him go into a dive from which he did not recover. His legs and a large manzanita bush absorbed the full force of impact, and death was probably instant. Strc::.;ngely, the kite was virtually undamaged and ready to fly again. It was not his blue and yellow kite, but rather another Flexi-Flier which he had flown many times. More will most likely never be known.

Dave Muehl, Ed's flying partner Rnd cousin, observes that 11 Eddie 1s spirit now flies with all of us. 11 In this it has been decided by Dick Eipper and Steve Wilson to name the trophy they are providing for the annual Lilienthal and Montgomery meets after Ed Gardia. Let's all remember Ed's joy in flight, and let's all remember to share that joy with safety always in mind.

Dave modified the ski,ghtly off-color lyrics of a Cat Steven I s piece Eddie liked, and this with other joyous. music was sung by a folk guitar group at the 'services on 3 October: Ed flew his kitR o 1er the land, And let the spirit of flight take his hand.

So he smiles when the wind blows.

And i t hlows • • • it will always blow.

And maybe•·this' is appropriate, also:

Look up to the high ground, And to each cloud look a.round.

For there shall ye find me, Soaring in eternity. ~the-Hominid Avian ___..

MO;QEltN FABRIC SE1\LEH J\ND Fil.BRIC FOR H;1.NG GLIDERf~

By Frank Colver During my constant search for new and better materials for covering and doping hang gliders I have come across a material for 11 doping 11 that I.think would be of interest to GROUND SKI:MIV1ER readers., I fir:::,t used this mat(~rial to put a natural finish on a new door in my mountain cabin and I was told that it wa:::, almo:::,t indestructible and vvould last a lifetime.

The name of the material is ~iatron, and the color was called Mirra-clear.

It said on the can that it could be :.med for coating bare steel and aluminum so I began to think about the possibility that such a to~gh mat~rial might have some potential for bonding cron to aluminum, and also for filling the pores of the ~acron over tie open areas.· Also, I wanted to check its heat resistance because I have been looking £or a doping material other than white glue that I co~.ld .run an iron over to reshrink a stretched spot in the covering without burning the sealing material.

I tested Diatron as a filler for the cloth and found that, because it has a plastic-like quality and does not shrink, it will fill the Penny's Poly-

ester in one coat. J,fter it is dry it remains flexible and the fabric feels like a sheet of plastic.

To test it as an adhesive. I placed a piece of the croth on an aluminum tube anrl painted the surface of the cloth. After it dried the Polyester cloth was stuck to the aluminum better than any other material I have tested before. When I pulled the cloth away the ~hatron stpyed on the aluminum~ I can iron over the coated 0acron and the Diatron shows no tendency to burn or bubble. It did turn only slightly yellowish brown when the same spot was ironed over several times. The color change was barely perceptible to the eye.

The material is completely waterproof and water beads up and rolls off the surface. I think that the major drawback is that it takes several hours to dry. It is apparently a moisture-cure resin and dries faster when the air i~, damp.

At a lumber yard in the mountains it cost $6.25 for a quart, so it is fairly expensive but I think that, because it takes only one coat, a quart would go a long way, especially if it's applied with a sponge brush.

The cloth I tested the Diatron on is the same material that I covered my CW-1 Skysa.il flying-wing hang glider with It ic, heat-shrinkable;· 100% Polyester sheath (dress) lining, available from any Penny's depart~~ht store It costs 98¢/yard, is 44 11 wide, w2ighs only .l. 3 oz /yard, and comes in .white .and also many bright colors" Polyester cloth is Tlacron bu.t has riot beE)n made by Du Pont Co" which owns the name Dacron·.' .

It comes in' 25-yard · bolts,~ and if two or more bolts are purchased, the price is only 75¢/yardo such quantities have to be ordered so there is a one-day delay in delivery.

DESIGN _FEATURES As shown in the accompanvinr; 2-viei:,1 drr1winp; an all-winp; confi13uration was chosen to keep emr,ty Peip;ht lm'!, facilitate take-off from a slope, and to simplify assembly and stora~e. A 3-niece wing having a 12-foot ceriter section and ti:10 re~ovable 8-foot tip sections permits storage in a box 6 feet by 12 feet by 30 i:rches deen. The resultinp; 28-foot span tor.ether with an empt,1 Peirr,ht of lr:~ss than 60 nounds and my 011n lip:ht wei.r:ht should produce the desired 10\' flvinp, and, sinkinr; speeds; The larp;e-chord elevator snanninp: the 12-foot center section is simple to hinge and actuate and should be vc,ry effective.

A loF ,r:ear ratio should prevent pilot-induced oscillations , 'ith t:hi~~ prn7 erful control.

Pritchard deF;cribed it as a ver'y lar'rre and lleavy hinJ.ane of r•oqc,hly the Panr Loooose variety with interplane rudders act11ated fror the cockpit and returned to neutral by strips of sur.r;ical tnbin'".

1.n··u not, yonr r;eporter said to himself, just mosey on over to Co,:iher Canyor, 1,;oci rl and see Phat Has Phat.

And, sure enou[';h, precisely ir the ac1vcrt iscd spot, Ha::; the rTlid.er.

And, sure enoup:h, it Fas lay,11e, had intc·rplanc rudders, suP.ri:ical tubinr: and all.

It also had a builder, if that's the proper term, one Tom Burnett of Hest Lilac ~\oad, F:f;conchclo, , 1!10 ,Yc1S bw::;y ma.kinri some repairs.

On Sunday a pi1ot had bailed out ancl the r~lickr,. lc:"ft to, its ov'n inclinations, had reared uP and landed on the left Pin 1, tip and tail, breakir1F a f ev1 members here and-there.

These fractl1res were now beinr, repaired with spare sticks and balinr.; Hire, al thour,h such was the state of thinr:s that once a repc1iL' Pas finished it v12ts ir1nossible to tell 11here it stopped and the rest of the ~licler besan.

Tor said this was his fourth ri:lider and that it had been assembled, more or less, from parts of two of the earlier ones.

These tNo had been biplanes; the ship unaccounted for was a bar~oo and polyethelene Ror:allo of which there i:,,ere t3till some remn2:m:ts scattereci abont. The finished product,. to put the matter ac:; kindly as possible, made. very fev! concessions to aesthetics.

The onlv noticeable bit of decor Has a brae~ of three small letters painted on the surface of the upper winp.

Thes~ I was informed, stood for Bonsall Air Farce.

Presently one of ~om's bt1dcties, non Fischer of San Luis Rey, arrived and bep;an stanlinp loose ends of polyethelene to th~ framework.

When this job was finished w~ carted the plicter up the slope for test fliphts.

Not to find hm·1 it Pould fly, mind you, but if :it l·'Ould fly.

Your reporter, who considers h:i.mself sof'lethinp: of ar expert on crashin1~ p;liders in p;eneral and the crashinr Hanp Loose in narticular, delivered his usual haranp;ue about the necessi 1:y of r:ettirw the Heiri:ht \·!ell forward and 1~eeping up a good head of steam once in the air (if one hoped to avoid the inevitable side slip and p;round loop), but as usual no one listened.

There was a r;ood vrind on the slone into 1'hich Tom ancl Don TPade some attempts.

The best of tf'e'.3e, 11(th Tom fl: inri:, if tha.t' s the proper tenn, r:ave me a chance to observe the controJ. system and its method of Operation.

Bonder of wonders.

Fror the inside corners of the aforementioned interplane ru~der~ lines run to the leadin~ ectre of the ~·in~ in the ar~a of the cockpit.

Every couple of feet alon(T these lines small lenpths of .wood are afixed.

Yet other wonders, too diverse to be mentioned, had obsct1red curiosity as to just how these small triumphs of advanced technolory v•ere 1

~~150. 00.

SCHGA Pre dent Lloyd cher met recently with Mrs.Seymour of Rancho La Sierra, manager the rope for mult owners re hang glider flying has been taking ce east of Norco, north of Arlington Ave . .The owners are sympathetic but do not want any more such a ivity on that property, so SCHGA members are d to raspect this private property.

Mrs. Seymourwas willing to give p rmission to use the hill above the Norco City Park ( undeveloped) area a"G the east end of 6th f3t., if suitable insurance could be provided, but it too rough is. An area west of Norco has good promise and will be checked out.
