The Wright brothers only flew together once
Orville and Wilbur Wright were the first people to fly a motor-operated aircraft in 1903 successfully. Their most significant achievement was creating a three-axis control system, which enabled the pilot to control the three critical flight dynamics parameters that determine the vehicle’s center of gravity: pitch, roll, and yaw.
Most of the flights were manned by only one of the brothers to avoid both of them being lost in case of an accident. One needed to survive to continue their experiments. They only flew together once, in 1910, after getting permission from their father since they had promised never to do so.
