Definition of Wright brothers

The Wright brothers, Orville (August 19, 1871 –  January 30, 1948) and Wilbur (April 16, 1867 –  May 30 1912), were two Americans who are generally credited with building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight on December 17, 1903. In the two years afterward, they developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made mechanical fixed wing flight possible.
