The Wright Brothers, Orville and Wilbur, are generally credited with making the first controlled, powered, heavier-than-air flight on December 17, 1903. By 1905 they had developed their flying machine into the world's first practical airplane, along with many other aviation milestones. Their feat is officially recognized by the Fédération Aéronautique Internationale (FAI) as being the first controlled, powered, sustained flight involving a heavier-than-air vehicle, using mechanically unassisted takeoff.
