The Eagle and the Hawk

Lt. Jerry Young (Fredric March) and Lt. Mike "Slug" Richards (Jack Oakie) join the Royal Flying Corps and are assigned to the dangerous mission of reconnaissance over enemy lines. During furious fighting, Jerry loses his air gunners/observers, one after the other, until only Henry Crocker (Cary Grant) is available to fly with him. Jerry's dislike of Crocker grows after Crocker shoots a parachuting German observer who bailed out of a blimp. They eventually become friends of a sort, but Henry realizes that the war is taking a toll on Jerry.
