A U.S. Air Force pilot poses beside his Douglas A-1 Skyraider, marked with a yellow "RESCUE" arrow denoting its role escorting combat search-and-rescue missions over Vietnam and Laos. The rugged, propeller-driven A-1 could absorb heavy battle damage and loiter over a downed airman for extended periods, making it indispensable to Air Force rescue operations throughout the war.
