He constructed an ornithopter, although its complete development was prevented by his untimely death on 9 August 1896 in a glider accident. In 1929, a man-powered ornithopter designed by Alexander Lippisch (designer of the Messerschmitt Me 163 Komet) flew a distance of 250 to 300 metres (800–1,000 ft) after tow launch. Since a tow launch was ...
The Riout 102T Alérion is an ornithopter built in 1937 designed by René Riout. The Alérion went through a series of ground tests including in the Chalais-Meudon wind tunnel 1938 when the wings suffered a structural failure. Further development was abandoned with the start of World War II.
The ornithopter was a high-wing monoplane, with the pilot seated in a recumbent position. Its construction followed conventional glider practice of the time. The fuselage had a bulkhead construction, covered in thin plywood. The wings featured a torsion-box spar and leading edge arrangement, and were also made from thin plywood.
A further advance was made on 9 August 1884, when the first fully controllable free flight was made by Charles Renard and Arthur Constantin Krebs in a French Army electric-powered airship, La France.

MIT Daedalus Project. 1988 Crete to Santorini flight, official FAI world records for total distance (119 km), straight-line distance, and duration (3 h 55 min) for human-powered aircraft. MIT Monarch A: USA: 1983: Mark Drela / Massachusetts Institute of Technology: 29 flights. MIT Monarch B: USA: 1984: Drela / Massachusetts Institute of Technology
They conducted several tests, but Orville made the first flight at 10:35 a.m., lasting 12 seconds and traveling 120 feet. Wilbur flew it the longest that day for 59 seconds and across 852 feet.
The craft was built under the University of Toronto's Human Powered Ornithopter Project. [10] The name came about when, during testing on a snowy field, the cockpit became filled with snow. [5] The team expects that revised iterations of the aircraft with greater performance will be made. [12]
Another advancement was made in 1884, when the first fully controllable free-flight was made in a French Army electric-powered airship, La France, by Charles Renard and Arthur Krebs. The 170-foot (52 m) long, 66,000-cubic-foot (1,900 m 3 ) airship covered 8 km (5.0 mi) in 23 minutes with the aid of an 8½ horsepower electric motor.
