A U.S. Army CH-47 Chinook transport helicopter idles on a rain-slicked airfield ramp somewhere in Vietnam, its twin rotors turning as ground crew stand by in the distance. The Chinook served as the workhorse of Army aviation during the Vietnam War, ferrying troops, artillery, and supplies to forward bases across difficult terrain. This snapshot, drawn from a personal 35mm slide collection, captures the routine rhythm of airfield operations amid the region's tropical climate. Project: 218406
