An airman poses beneath a retired A-1 Skyraider propeller mounted as a unit display, marked with the aircraft's nickname 'SPAD.' The Skyraider, a rugged propeller-driven attack aircraft, was flown extensively by U.S. Air Force Special Operations and Air Commando squadrons in the Sandy rescue-escort and close air support roles during the Vietnam War, prized for its heavy ordnance load and long loiter time over the battlefield.
