1943 finds the United States Army Air Forces at full stretch, training officer candidates on the sand of Miami Beach one year and sending them into the flak over Schweinfurt the next. This History Hit production draws on newly restored film and newsreel footage to trace the arc of the 2.5 million men and women who served in the air arm, from stateside classrooms and flight schools to the bomber formations grinding through daylight raids over Germany. The restored material is the film's real asset: cockpit views, ground crews arming aircraft, and burned airfields that have not circulated widely before. Rather than following a single crew or campaign, the narration moves through the training pipeline, the strategic bombing campaign, and the mounting losses over targets like Schweinfurt, using period footage to carry most of the story. It is a broad survey of how an air force built almost from scratch became the force that helped break German industry, told largely through the images its own cameramen shot at the time.
