This Douglas A-1 Skyraider, nicknamed 'Lieutenant America,' represents the rugged, propeller-driven attack aircraft flown by U.S. Air Force 'Sandy' pilots during the Vietnam War to escort search-and-rescue helicopters and provide close air support for downed airmen and special operations teams. Here, ground crew prepare the aircraft with its wing folded for storage or towing, a routine seen at airfields throughout the Skyraider's long service life. Project: 219290
