...except be first to fly a powered heavier-than-air craft, which one of them was.
And truly, the Wright Flyer didn't accomplish much either, except to fly further and more reliably than any HTA craft had done before. I don't minimize this, it was a great accomplishment. The Wrights' accomplishment, really, was to demonstrate sufficient engineering and design skills to reliably repeat the experiment. All the developments in aircraft technology immediately following the flight at Kitty Hawk were based on their design, including the brothers' own work with Glenn Curtiss.
Lots of people flew before. The landing is the tricky part.
And invent the ailerons or wing warping as they called it. Not to mention the use of a wind tunnel and the reinvention of the tables used to design wings, the lift tables they were using before they used a wind tunnel were wrong. They improved them and their initial work was used in air craft design by others and still is.
The Wright brothers pioneered practical aviation, without their pioneering inventions we would not be where we are today in Aviation.
