Not the first, it was done 30 years ago, Google Gossamer Albatross.

Ummm... ...no.

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.

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.

This one was not an ornithopter either...
It just LOOKS like one...

How do you conclude that?

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.

Well, to be atrue ornithopter, its takeoff would not be towed by an
automobile, for the first thing.
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.

You're reaching a little bit, I think.

It was definitely flapping its wings and the folks who built it know how
to make that work. They based it on a powered ornithopter that achieved
flight on its own from a standing start.
