The Wright Flyer, also known as the Kitty Hawk, made the first sustained flight by a manned heavier-than-air powered and controlled aircraft – an airplane – on December 17, 1903. Invented and flown by the Wright brothers, it marked the beginning of the pioneer era of aviation. The Wright Flyer is a single-place biplane design with anhedral (drooping) wings, front double elevator and rear double rudder. It used a 12-horsepower (9-kilowatt) gasoline engine powering two pusher propellers. Employing "wing warping", it was relatively unstable and very difficult to fly. The Wright brothers flew it four times in a location south of Kitty Hawk, North Carolina. The airplane flew 852 feet (260 m) on its fourth and final flight, but was damaged on landing, and minutes later was wrecked when powerful gusts blew it over. The aircraft never flew again but was shipped home and subsequently restored by Orville Wright. It was housed in the Science Museum in London from 1928 to 1948, and is now exhibited at the National Air and Space Museum in Washington, D.C. This photograph, taken by John T. Daniels, a local member of the United States Life-Saving Service, shows the Wright Flyer seconds into its first flight in 1903.Photograph credit: John T. Daniels; restored by Lise Broer
