A Douglas A-1 Skyraider, its cowling adorned with shark-mouth nose art, skims low over the water during the Vietnam War. Nicknamed the 'Spad' for its WWII-vintage propeller design, the A-1 remained in front-line USAF service into the late 1960s, prized for its long loiter time, heavy ordnance load, and rugged survivability — qualities that made it the aircraft of choice for escorting search-and-rescue helicopters into contested territory.
