Three A-1 Skyraiders in their revetments at a Vietnamese airbase, photographed from a passing aircraft. A unit emblem painted on the outer face of the revetment wall marks the squadron's assigned bays - a common way for units to claim their patch of a crowded flight line. Yellow tugs, power carts, chocks and fire extinguishers wait at each aircraft, and a line of crash rescue trucks stands ready outside the fire station beyond. Project: 219827
