TheWright brothers,Orville(August 19, 1871– January 30, 1948) andWilbur(April 16, 1867– May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited[1][2][3]with inventing, building, and flying the world\'s first successfulairplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south ofKitty Hawk, North Carolina. In 1904–05 the brothers developed theirflying machineinto thefirst 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 fixed-wing powered flight possible.

The brothers\' fundamental breakthrough was their invention ofthree-axis control, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium.[4][5][6][7]This method became and remains standard on fixed-wing aircraft of all kinds.[8][9]From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving \"the flying problem\". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines.[10]Using a small homebuiltwind tunnel, the Wrights also collected more accurate data than any before, enabling them to design and build wings and propellers that were more efficient than any before.[11][12]Their first U.S. patent, 821,393, did not claim invention of a flying machine, but rather, the invention of a system of aerodynamic control that manipulated a flying machine\'s surfaces.[13]

They gained the mechanical skills essential for their success by working for years in their shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles in particular influenced their belief that an unstable vehicle like a flying machine could be controlled and balanced with practice.[14]From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their bicycle shop employeeCharlie Taylorbecame an important part of the team, building their first airplane engine in close collaboration with the brothers.

The Wright brothers\' status as inventors of the airplane has been subject to counter-claims by various parties. Much controversy persists over the manycompeting claims of early aviators. Edward Roach, historian for theDayton Aviation Heritage National Historical Parkargues that they were excellent self-taught engineers who could run a small company, but they did not have the business skills or temperament to dominate the growing aviation industry
