What is Ornithopter?
[[File:Skybird.gif|thumb]] An '''ornithopter''' from the ancient [[Ancient Greek language|Greek]] language is an [[aircraft]] that flies by flapping its [[wing]]s. Designers try to make the flapping-wing flight of birds, bats, and insects seem real. Though [[machine]]s may differ in form, they are usually built on the same scale as these flying creatures. Manned ornithopters have also been built, and some have worked. The machines are of two general types: those with engines, and those powered by the muscles of the [[pilot]]. {{transport-stub}} [[Category:Aircraft]]
