A restored Douglas A-1 Skyraider taxis under its own power during a Tennessee airshow. Known to Vietnam-era aircrews as the 'Spad' or, in its search-and-rescue escort role, 'Sandy,' the Skyraider was prized for its long loiter time, heavy ordnance capacity, and rugged survivability while supporting downed airmen and ground troops in Southeast Asia.
