Book excerpt: The reissue of this definitive biography heralds the one-hundredth anniversary of the Wright brothers' first flight. Brilliant, self-trained engineers, the Wright brothers had a unique blend of native talent, character, and family experience that perfectly suited them to the task of invention but left them ill-prepared to face a world of skeptics, rivals, and officials. Using a treasure trove of Wright family correspondence and diaries, Tom Crouch skillfully weaves the story of the airplane's invention into the drama of a unique and unforgettable family. He shows us exactly how and why these two obscure bachelors from Dayton, Ohio, were able to succeed where so many better-trained, better-financed rivals had failed.
