A pilot climbs down from the cockpit of his A-1 Skyraider after a mission, helmet and oxygen mask in hand, as a crewman reaches up to assist him. Scenes like this played out on flight lines throughout South Vietnam and Thailand as Skyraider pilots flew repeated close air support and search-and-rescue escort sorties, often for hours at a time, in one of the most physically demanding roles of the air war.
