The Wright Brothers

Orville Wright and Wilbur Wright were two American aviation pioneers. They were credited as the ones who invented, built, and flew the first motor-operated airplane.

They successfully enabled full controlled and sustained flight in December 1903. The Wright Brothers did their first four 12-seconds flights over North Carolina. A handful of people witnessed them.
