Douglas A-1 Skyraider, tail number 665, nicknamed "Lieutenant America." This rugged, propeller-driven attack aircraft served with U.S. forces during the Vietnam War era, prized for its heavy ordnance capacity and long loiter time in close air support and rescue-escort roles. Shown here with its outer wing panel folded, a feature that allowed Skyraiders to be stowed compactly aboard aircraft carriers. Project: 219306
