The Snowbird is a very light aircraft, weighing only 43 kg (94 pounds). It is built from kevlar, foam and balsa wood and is powered by the human body. Such an aircraft is called an Ornithopter. On 2 August 2010, Todd Reichert, a Canadian student, powered and flew the Snowbird for 19.3 seconds, maintaining an altitude of three metres, and flying at an average speed of 25.6 km/h (16.5 mph). It flew 145 m (476 ft) at the Great Lakes Gliding Club in Tottenham, Ontario. Whereas the Gossamer Condor became the first human powered aircraft capable of sustained and controlled flight in 1977, the Snowbird, which has a wingspan of 105 feet, comparable to a Boeing 737, is the first to flap its wings like a bird for propulsion and actually sustain level flight, thus fulfilling one of man's earliest ambitions.
