Wright Brothers Achieve First Powered Flight
On December 17, 1903, Orville and Wilbur Wright made history at Kitty Hawk, North Carolina, completing the first successful powered, sustained, and controlled airplane flights. The first flight lasted just 12 seconds and covered 120 feet, but by the fourth attempt that same morning, Wilbur flew for 59 seconds and covered 852 feet. The brothers had spent years studying bird flight and experimenting with gliders before perfecting the engine and propeller system that made powered flight possible. Their achievement at Kitty Hawk — witnessed by only five people — transformed civilization: within 66 years of that first flight, humans would walk on the Moon.
