It's all about the patent on the 1902 Wright glider. A glider, not a powered aircraft. The patent was for three axis control. Pitch, roll, and yaw. Three axis control is used in ALL aircraft, rockets, and submarines. They protected their patent and won. The Wrights are given credit for this discovery. Others may have messed around with it but the Wrights identified and developed it, and got the patent. The picture I posted earlier was of this very glider demonstrating three axis control in flight. Better to figure out how to fly first before stuffing an engine into it. Kind of like the bicycle before the motorcycle!
