Wilbur and Orville Wright inaugurated the aerial age with their historic first powered airplane flights at Kitty Hawk, North Carolina, on December 17, 1903. The brothers used this stopwatch to time the flights. The first effort covered 120 feet in 12 seconds. On the best of the four flights made that day, the Wright Flyer traveled 852 feet in 59 seconds.
