Twelve O'Clock High (1949)

In 1942, an American Air Force unit stationed in England is plagued with morale problems until no-nonsense Brigadier General Frank Savage (Gregory Peck) assumes command. His tough leadership is initially resented by not only his pilots but his second-in-command (Hugh Marlowe), a West Point graduate and son of a general. But, with the help of a hotshot flying ace (Robert Patten) and a sympathetic administrator (Dean Jagger), the unit pulls together into a gung-ho fighting crew.
