On December 17, 1903, at Kitty Hawk, North Carolina, the Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard. Between 1899 and 1905, the Wright brothers conducted a program of aeronautical research and experimentation that led to the first successful powered airplane in 1903 and a refined, practical flying machine two years later. Their method of evaluating data gathered by testing an aircraft in flight, then refining the design based on those results, remains an essential tool in aerospace research and development.
