A design for a human-powered flying machine developed by Sir George Cayley in 1853. The career of Englishman Sir George Cayley marked a turning point in the history of aviation. Cayley was the first to mount a well-conceived, systematic program of aeronautical research grounded in the scientific method. He conducted practical experiments in aerodynamics, published his findings in scientific journals, and performed flight tests with models and full-size gliders.
