Forget the previous link, it was incorrect, here is the story I wrote in 2002:
As an old time hard core Dac pilot (my bird was on the cover of the National Geographic August '83) I saw the KitPlanes article and immediately started to see if any misconceptions or errors were there about the mighty Dac. None were, you did a great job on getting across what a unique and still very cool aircraft the Dac is! I put over 600 hours on various wings, and once flew over 1600 miles up into Canada (Gimli) on a solo XC. This was back when the other ultralight designs were lucky to get off the damn ground, much less go anywhere. My favorite trick was keeping a roll of toilet paper on the inboard compression stmt, very handy while camped out and a huge laugh guaranteed when shown to others.' I wrote the following story after 9-11, the first time I'd put down on paper what had happened. Enjoy. (PS I fly a Rans S-7 Courier now, great bird if you ever want something different)
During the early 1980s I was selling, building, flying, and training others in ultralight aircraft. The “PteroDactyl” was my choice of aircraft, it had excellent rough/short field capabilities, I was very familiar with the airframe, having flown Manta Fledge hang gliders, which the Dac wing was based on, it had great climb performance, useful in the mountains of Idaho, and the company prez, Jack McCornack was a lot of fun to deal with. Those who know Jack know what I mean!
I was helping to man the official Pterodactyl booth at the 1981 S&F Event as part of my unofficial duties as a good Dac dealer, it was fun meeting all the interesting people and talking flying non-stop, and it freed up Jack to do who knows what. During the second day I had a longer then usual conversation with a couple in their mid 20s, Roger was going to Harvard, and was obviously well bred, plus a nice guy. His lovely young wife, whose name escapes me, was very interesting to look at, I couldn’t quite pin down her country of origin however, she clearly was not US born. Roger’s questions about the Dac quickly turned to its high altitude performance and payload capability. I told him I routinely flew over the highest mountains in Idaho and other western states while packing full camping gear, he was very intrigued by that, as most were. Then I mentioned how one person could break it down in less then an hour and throw it on a compact car without even needing a roof rack, how it could operate safely out of plowed fields, and it also was a good power off soaring machine. Over the next couple days Roger and his wife came back to chat several times, and we got to know each other. The last day of the event he confided his real interest in the Dac: his wife was a member of the exiled Afghan royal family, and he was looking for the ultralight most capable for the mission he had in mind.
The mission was to help the Afghan freedom fighters battle the Soviet invaders with Pterodactyls! It seemed that the Soviets were well aware of the lack of aircraft equipped freedom fighters, and were lax in protecting their compounds from aerial attack. The idea was that some serious damage could be done by the first few Dac attacks, after that, heavy casualties could be expected by the flying freedom fighters, but that was a sacrifice they were willing make.
The following month Roger and his wife flew out to Idaho, and stayed for 2 weeks while I demonstrated the Dac’s flight performance carrying different payloads representing different weapon systems. He had a catalog, (who know where he got it, but his uncle was a past director of the CIA during the Nixon administration), that had all kinds of lethal weaponry, their sizes and weights. Roger assiduously videotaped every flight, also the complete procedure of assembly and disassembly. They had purchased a Dac from me, I trained him to fly it, and he did quite well. The second week they were visiting her uncle arrived for a few days, he had just been released from a Russian prison camp. He looked like a holocaust survivor, very emaciated; he had been chief physician at the largest hospital in Kabul and as such was imprisoned in the Soviet effort to undermine the Afghan society. When he first arrived I was drilling some holes in my concrete shop foundation, which was under construction. He was very interested in the rotary impact drill, the reason being that the freedom fighters were fighting Hind helicopter gunships while exposed on rocky slopes, and he thought such a tool might be able to make a hole big enough for a man to hide in! That really brought home what they were dealing with over there.
As their visit drew to a close, Roger made me an offer: I could be flown to Pakistan, and assist in training select members of the freedom fighters to fly Dacs, and they would train others. Instruction in assembly and disassembly would be followed by a nighttime trip over the Khyber Pass with donkeys carrying the broken down aircraft. I could participate in that also, and perhaps even a combat mission if I desired. Fat chance! My life was not that boring to need such a major adrenalin fix, I got that flying local. I never heard from Roger again, the sale of dozens of Dacs never materialized, the covert supplying of Stinger missiles by the US government to aid the freedom fighters no doubt proving a more effective weapon then a 200 lb ultralight.
