The main contribution of the Wright brothers is the controls used on aviation (pitch, yaw and roll). About being the first, Santos-Dumont is recognized by Fédération Aéronautique Internationale as the first flight with witnesses. Splitting hairs here, the english word “airplane” is less specific than the french word “avion”. All avion are airplanes, but to be an avion the machine needs to be able to take off and land by its own means, and that’s the point where the first flight of the Wright brothers are missing. And as they kept secrecy on what they were doing, we don’t know exactly when they introduced each innovation on their machines. But to me, that doesn’t matter much actually. Heavier-than-air flights are more like a collective effort IMHO with the Wright brothers, Santos-Dumont and many others contributing to create the aviation.
