The Wright brothers managed to manufacture a controllable airplane, capable of gliding during a short flight, which took off propelled by means of a catapult, enough to test the turning and control system of the airplane. Although it is affirmed that its first flight was made on December 17, 1903, there are some doubts about it since there is no official certification.
They established the basis for flight control of heavier-than-air aircraft. To do so, the brothers used an aerodynamic tunnel they built to measure the lift of different airfoils at different angles of attack.
