"I think there is a man powered airplane somewhere. I remember reading
that a college class had built it to meet a challenge of flying a 1/4
mile (or thereabouts) course. It looked like a giant ultralight with a
huge wingspan and was powered by a man (in very good shape) using a
pedal system to drive the propeller. Totally impractical as a flying
machine, but interesting anyway. Perhaps someone in the group will
remember more about this accomplishment.
