A Douglas A-1 Skyraider sits armed and ready in a steel revetment somewhere in Southeast Asia during the Vietnam War. Nicknamed the "Spad" for its propeller-driven, World War II-era design, the A-1 remained a mainstay of close air support and search-and-rescue escort missions well into the jet age thanks to its heavy ordnance load, long loiter time, and rugged durability. Ground crew and flight personnel in olive-drab flight suits prepare the aircraft, its wings loaded with rocket pods, ahead of a mission. Project: 218965
