Wilbur and Orville Wright are credited with designing and building the first fixed wing aircraft. They made the first flight in their “Flyer” on December 17, 1903 in Kitty Hawk, North Carolina. Their critical innovation was the invention of three-axis control, allowing them control of their flying machine. Three-axis control, allowed them to control roll (side to side rotation), pitch (up and down), and yaw (front to back rotation). They filed and received U.S. Patent 821,393 for invention of the system that would allow them to establish control of roll, pitch and yaw, and not for the invention of a flying machine or aircraft.
