On a winter day in 1903, in the Outer Banks of North Carolina, two unknown brothers from Ohio changed history. But it would take the world some time to believe what had happened: the age of flight had begun, with the first heavier-than-air, powered machine carrying a pilot. Who were these men, and how was it that they achieved what they did? David McCullough, two-time winner of the Pulitzer Prize, tells the surprising, profoundly American story of Wilbur and Orville Wright.
