On Dec. 17, 2003, America looked back a century to celebrate the first successful flight of a powered airplane. Ten years after the Centennial of Flight, Orville and Wilbur Wright’s achievement at Kitty Hawk is still inspiring creativity and provoking discussion. In time for this year’s anniversary, the Smithsonian’s National Air and Space Museum is introducing 21st-century projects that relate to the brothers and their 1903 Flyer, one of the Smithsonian’s most iconic artifacts, and shining a light on its popular exhibition, “The Wright Brothers & The Invention of the Aerial Age.”
