A bomb-laden A-1 Skyraider, affectionately nicknamed the 'Spad' by its crews, sits within a protective revetment at Nakhon Phanom Royal Thai Air Force Base. NKP served as the home of U.S. Air Force Special Operations squadrons flying the Skyraider on 'Sandy' rescue escort and interdiction missions over Laos during the Vietnam War. Revetments like this one protected valuable aircraft from enemy rocket and mortar fire. Project: 219021
