Who found the first plane?

The first airplane was invented in 1903 by Wilbur Wright and Orville Wright (brothers). It flew for 12 seconds

ANS 2 - MANY inventors across the world invented and flew short flights in aircraft before the Wright brothers. Nobody 'discovered' the first aircraft - they were developed after much trial and many errors in the USA, France, Britain and other countries all through the late 1800's. The Wrights were famous because they perfected control of their Wright Flyer and made the first provable short flight.

Gustav Whitehead, a German born engineer in Connecticut may in fact have made the first powered, human controlled flight, but simply had no idea about getting major publicity, as the Wrights did.
