The Douglas A-1 Skyraider, seen here in period Vietnam-era camouflage, was a rugged, propeller-driven attack aircraft that could carry a heavier ordnance load than many contemporary jets while loitering longer over the battlefield. Flown by U.S. Air Force Air Commandos, Navy aviators, and the South Vietnamese Air Force, the 'Spad' became legendary for its role escorting search-and-rescue helicopters as call sign 'Sandy,' protecting downed airmen deep in hostile territory.
