The first flight of the Wright brothers lasted 12 seconds and 120 ft (36.5 m): shorter than the wingspan of a Boeing 747.
After several unsuccessful attempts, on December 17, 1903, at Kill Devil Hills near Kitty Hawk, North Carolina, Orville Wright completed the first powered flight of a heavier-than-air aircraft known as the Wright Flyer. The flight lasted just 12 seconds, traveled 120 feet, and reached a top speed of 6.8 miles per hour.
