U.S. Air Force airmen share a celebratory toast on the flight line, a tradition often associated with completing a 'fini flight' -- a pilot's last combat mission of a tour. Photographs like this, taken at an air base in Southeast Asia during the Vietnam War, capture the camaraderie and rituals that bound aircrews together far from home, alongside the everyday work of the ground crews who kept the mission running.
