A U.S. Air Force A-1 Skyraider — affectionately nicknamed the 'Spad' by its pilots — sits on a rain-soaked flight line at a Vietnam War air base, its pilot in the cockpit and a ground crewman standing watch beneath the wing. The rugged, propeller-driven Skyraider carried heavy ordnance loads on close air support and combat rescue escort missions throughout the war. Project: 219603
