The first fly of the history was made by the french Clement Ader in 1890.


Clement Ader is credited with being the first to get a powered,
man-carrying, heavier-than-air machine aloft. I don't think anybody
disputes that. But as Ader had not equipped the craft with any kind of
flight control system, this was obviously not controlled flight. That's the
key point about the Wright's flights on December 17, 1903. There is no
credible evidence that anyone achieved powered, sustained, controlled
heavier-than-air flight before the Wright brothers. CONTROLLED flight, that
is the key.
