Two Douglas A-1 Skyraider attack aircraft fly in formation above the clouds during the Vietnam War. Nicknamed 'Spad' or, in the rescue-escort role, 'Sandy,' the rugged, propeller-driven Skyraider carried a heavy ordnance load and long loiter time, making it a mainstay of close air support and combat search-and-rescue missions for the U.S. Air Force and Air Commando squadrons throughout the conflict.
