A U.S. Air Force A-1H Skyraider, tail code '6T,' cruises above the clouds during a Vietnam War-era mission. Nicknamed the 'Spad' for its propeller-driven, WWII-style design, the Skyraider carried heavy ordnance loads and long loiter times that made it invaluable for close air support and 'Sandy' rescue-escort missions protecting downed aircrew.
