First Flight: Conquest of the Skies

Who gets credit for the world's first motorized flight? We're all taught that Orville and Wilbur Wright flew first in December 1903. Australian aviation expert John Brown argues that German-born Gustave Whitehead flew before in 1901.

To display the Wright flyer the Smithsonian Museum agreed that it will never claim that anyone flew before the Wrights. History may not be as certain as we thought.
