Query: Teaching the Wrights to Fly

Edward Chalmers Huffaker made the first powered (though unmanned) flight while Alexander Graham Bell stood beside him, and he was the first physicist to apply the Bernoulli principle to airplane wing lift. This well-researched history of Huffaker's life and his uneasy relationship with Wilbur and Orville at Kitty Hawk chronicles his key role in the development of aviation. The Unwelcome Assistant is a compelling and enlightening book.
