GEORGE BUSH PTodamation 6391 of December 12, 1991 Wright Brothers Day, 1991 By the President of the United States of America A Proclamation They were quiet men of modest means, but in an extraordinary display of talent, imagination, and teamwork, Orville and Wilbur Wright changed the world. Less than a century ago, on December 17, 1903, these enterprising brothers launched the age of aviation with the first controlled, manned flight in a heavier-than-air, mechanically propelled airplane. Although their handcrafted "Flyer" covered just 120 feet on its maiden voyage over the windswept beach near Kitty Hawk, North Carolina, the Wright brothers helped lead mankind on a great joiuney of discovery and progress that continues to this day. Given the routine nature of air travel today—as well as the increasing frequency of shuttle missions and other forms of spaceflight—it can be difficult for us to fathom just how remarkable the work of the Wright brothers was. When they began to experiment with airplane models and wind tunnels at their small workshop in Dayton, Ohio, many people believed that human flight would never be possible. At that time, even the automobile had not yet appeared on the American scene. Defying the skeptics, Orville and Wilbur Wright persevered through months of careful study, calculation, and design. Indeed, long before they began constructing their first flying machine, the Wrights immersed themselves in the study of existing texts and papers on fundamental aerodynamics. They also conducted exhaustive research, moving far beyond previously accepted data and theories, many of which had proved to be unreliable. The Wrights* achievement of three-axis control in flight, inspired by watching birds of the air, laid the foundation for their success at Kitty Hawk and for the futm-e development of all aviation.
