A restored Douglas A-1 Skyraider, painted in its Vietnam-era camouflage colors, taxis at a Tennessee airfield during a 2014 air show. The rugged, propeller-driven Skyraider served as a mainstay of U.S. close air support and combat search-and-rescue escort ('Sandy') missions throughout the Vietnam War, prized for its heavy weapons load and long loiter time over the battlefield.
