And the others kept crashing so they where banned.
Banned? by who? Every nation in the world uniformly banned flight attempts?
In fact there was unpowered glider flight before the Wright brothers. Go look at Jean Marie le Bris.
Alexander Mozhaysky Made a powered take off some 20 years before the wright brothers, though he only went 60 feet.
Alberto santos Dumont made a powered flight a few years after the wrights, with his own design.
There are others.
Now, why do you want flight to not work?
