A U.S. Air Force pilot, dressed in a flight suit and survival vest, strikes a lighthearted pose on the flight line of a Southeast Asia air base during the Vietnam War. Behind him, corrugated-steel revetments sheltered parked aircraft from enemy shelling, while a stenciled FOD barrel reminded ground crews to keep the ramp clear of debris that could damage jet engines. Photographs like this one capture the everyday camaraderie of aircrews between combat sorties. Project: 219080
