Warbird Associates Inc. The Douglas A-1 (formerly AD) Skyraider was an American single-seat attack aircraft that saw service between the 1950s and early 1970s. It was a propeller-driven anachronism in the jet age, and was nicknamed "Spad", after a World War I fighter. However, the Skyraider had a remarkably long and successful career and inspired a straight-winged, slow-flying, jet-powered successor, the A-10 Thunderbolt II (Warthog).
