An Air Force officer poses beside the hand-painted 'Home of the Spads' sign marking a detachment of the 56th Special Operations Wing, whose A-1 Skyraider pilots earned the nickname 'Spads' after the WWI-era SPAD fighter. Though built in the propeller era, the rugged A-1 remained a mainstay of close air support and rescue escort missions throughout the Vietnam War. Project: 218824
