A U.S. Air Force A-1 Skyraider pilot, wearing his leather flight helmet and survival vest, pauses on the flight line beside his aircraft's camouflaged tail, marked "TS" with serial AF 37-628. Ground crew work nearby amid the protective revetments common to Vietnam-era airbases. The A-1 "Spad," though a propeller-driven holdover from an earlier era, proved indispensable for close air support and combat rescue escort throughout the war. Project: 219603
