Orville and Wilber Wright started to design the first draft of their airplane Wright “B” Flyer in August of 1899. It was a two-winged kite with a wingspan of 5 feet. The flight was a success, which encouraged other attempts. Based on the success of the flight in September of 1900, they built a 17 feet glider which they tested at Kittyhawk, North Carolina. Between September 1901 and August 1902, the Wright brothers tested over 50 different planes until they had accurate data for building a third glider. It had a wingspan of 32 feet. On December 17th, 1903, Orville Wright made the first flight with a self-propelled airplane. This event has marked the beginning of modern aviation.
