Kitty Hawk and Kill Devil Hills are American place names that will live in history. Here Wilbur and Orville Wright, two unassuming brothers with a passion for advancing aeronautical knowledge, and the willingness to undertake a scientific adventure, made the world’s first successful flight of a man-carrying, power-driven, heavier-than-air machine.

December 17, 1903, was the day man first flew in this machine. It was a cold and windy day when Orville Wright climbed aboard their plane at 10:35 a.m. His first power-driven flight of 120 feet lasted just 12 seconds when he flew over a wind-swept stretch of level sand now preserved at Wright Brothers National Memorial. From those moments the science of aeronautics has borne the impress of the Wrights’ achievements.
