A Douglas A-1 Skyraider sits on a perforated-steel-plank ramp at Nakhon Phanom Royal Thai Air Force Base, home to USAF 'Sandy' rescue-escort and Special Operations Skyraider squadrons during the Vietnam War. The rugged, propeller-driven Skyraider could absorb heavy battle damage while delivering close air support and covering downed-aircrew rescues. Project: 219105
