A Douglas A-1 Skyraider, nicknamed 'Spad' by its crews, displays iconic shark-mouth nose art on its cowling. Airmen prepare near the cockpit before a mission. The rugged, propeller-driven Skyraider was prized during the Vietnam War for its heavy ordnance load and long loiter time, making it a mainstay of close air support and 'Sandy' search-and-rescue escort missions.
