Through the invention of powered flight, Wilbur and Orville made significant contributions to human history. In their Dayton, Ohio, bicycle shop these two men, self-trained in the science and art of aviation, researched and built the world’s first power-driven, heavier-than-air machine capable of free, controlled, and sustained flight. The Wrights also perfected their invention during 1904 and 1905 in their hometown of Dayton.
