This Bureau of Aeronautics three-view drawing depicts the Douglas AD-4 Skyraider, a rugged, propeller-driven attack aircraft designed for carrier operations. Later redesignated the A-1 Skyraider, the type became famous during the Vietnam War for its heavy ordnance capacity and long loiter time, flying close air support and combat search-and-rescue escort ('Sandy') missions for downed aircrew.
