No single human invention has transformed war more than the airplane—not even the atomic bomb. Even before the Wright Brothers’ first flight, predictions abounded of the devastating and terrible consequences this new invention would have as an engine of war. Soaring over the battlefield, the airplane became an unstoppable force that left no spot on earth safe from attack. Drawing on combat memoirs, letters, diaries, archival records, museum collections, and eyewitness accounts by the men who fought—and the men who developed the breakthrough inventions and concepts—acclaimed author Stephen Budiansky weaves a vivid and dramatic account of the airplane’s revolutionary transformation of modern warfare.
