Controlled, powered flight seemed impossible until Orville Wright took off on December 17, 1093 (102 years ago Saturday). The key to their success was their engineering which had gone beyond the trial and error methods of their contemporaries. Having very limited resources, they showed great scientific ingenuity, including their famous wind tunnel experiments. They were the first to understand how lift from the airfoil changes in flight, and the first to design their propellers as a form of airfoil.
Thank you, Orville and Wilbur, for our gift of flight!
