Twining Ornithopter


American Harry LaVerne Twining built himself a man-powered ornithopter which was tested late in 1909. It consisted of a tricycle to which articulated 8.2-m (27-ft) wings, operated by foot stirrups, were attached. The Los Angeles Daily Times dubbed it 'Twining's Flip- Flop' and assured worried readers that Twining did not intend to rise far from the ground at first, which was just as well be-cause the flip-flop was a complete flop, flapping furiously along a Los Angeles street but barely rising an inch.
