On the 17th December 1903, American brothers Orville and Wilbur Wright successfully made the first controlled, powered and sustained heavier-than-air human flight. Their aircraft, known as the Wright Flyer but later referred to as Flyer I, made its historic flights about four miles south of the town of Kitty Hawk in North Carolina. Four flights were made on the day, with the first by Orville lasting for just 12 seconds over a total distance of only 36.5m.
The brothers originally went into business selling, repairing and designing bicycles. However, by the end of 1899 they had developed a keen interest in flight, and began to devise control systems that could be employed on manned gliders. Their justification was that it was pointless to create a powered aircraft before a reliable control system had been designed. Their research led them to develop three axis control: wing-warping to control the roll of the aircraft, a moveable rudder to control yaw, and elevators to control the pitch.
Successful testing of these controls on a glider in 1902 led the brothers to build an engine to power their flying machine, along with a pair of specially-designed propellers that were refined under testing in their own wind tunnel.
After a number technical delays, the brothers tossed and coin to decide who would be the first to fly on the 14th December. Wilbur won, but stalled the engine on take-off and crashed the plane after just a three-second flight. After repairs, Orville became the first to pilot the aircraft on its first true flight three days later. Each brother successfully flew twice that day.
