The Kremer prize for the first human powered *flight* was won by the Gossamer *Condor* in 1977. The Gossamer Albatross won the prize for human powered flight between France and England on June 12, 1979. But neither of them was a human powered *ornithopter*: an aircraft that works by flapping its wings. -- Alan Baker Vancouver, British Columbia http://gallery.me.com/alangbaker/100008/DSCF0162/web.jpg |

GA was prop-driven, not an ornithopter (thrust from wing flapping). This one doesn't seem to have enough power to take off on its own, but enough to barely maintain level flight. Mildly creepy looking under weigh; looks like a sailplane with severe low-frequency flutter. |

And secondly, it should be able to sustain flight by flapping. This thing was simply a unique-looking glider with wings that flexed a bit in ground effect, after the car towing it got it moving. It may indeed be a comendable piece of aerdymanic ingenuity, but an "ornithopter it is NOT. Flash |

How much flapping do you have to do before it's an ornithopter? Not being able to take off under its own power doesn't help, mind. |

Oh, I'd guess - enough for the wings to actually FLAP rather than just FLEX. -- Richard Lamb |
