During the great air battles that were fought to destroy Nazi Germany's ability to wage war, one group was especially distinguished. They were called the Hell's Angels. This is the story of the 303rd Bomb Group, as told by the men who made it what it was. Taking their name from the B-17s they flew, they became one of the most important air combat units in history. The dramatic and terrible air battles they fought against Germany changed the course of World War II.
