Members of a U.S. Air Force A-1 Skyraider squadron pose beneath the propeller of one of their aircraft in April 1970. The mix of flight suits and fatigues reflects the combined aircrew and maintenance personnel who kept the rugged, propeller-driven Skyraider flying combat and rescue-escort missions in Southeast Asia. The perforated steel planking underfoot was standard surfacing for the improvised runways and ramps of Vietnam-era forward air bases. Project: 219902
