Photograph. Luftwaffe ground crewmen working on German Heinkel He 111 bomber engine at night. Translation of official German caption on photo reverse: "Comrades in [flight] arms. The ground crews work tirelessly. Even at night they are on duty. As soon as the He 111 returns from a night flight to England, the comrades in their black overalls are on it, to inspect the aircraft from the motor to the tail, and ready the aircraft for the next takeoff.
