A U.S. Air Force A-1 Skyraider banks over the mountainous jungle of South Vietnam during a combat sortie. Nicknamed the "Spad" for its propeller-driven, WWII-era design, the rugged A-1 remained in frontline service through the Vietnam War, prized for its heavy ordnance load, long loiter time, and durability — qualities that made it a favorite of close air support and search-and-rescue ("Sandy") pilots.
