Challenging the myth of the Wright brothers as equal partners in creating the “first flying machine,” William Hazelgrove offers a new perspective on their achievement. He shows how each brother plays a distinct role, arguing that Wilbur leads the design of the first successful airplane while Orville supports the mechanical work. Drawing on archives and family letters, he traces their experiments at Kitty Hawk, and their conflicts with the Smithsonian and Glenn Curtiss, revealing the personalities, struggles, and determination behind the birth of powered flight.
