Two Douglas A-1 Skyraider attack aircraft, painted in Vietnam-era camouflage, taxi across the grass at a warbird gathering. The Skyraider, a rugged single-engine, propeller-driven aircraft, served with distinction in close air support and search-and-rescue escort ('Sandy') roles during the Vietnam War. Surviving examples like these are lovingly maintained by private owners and museums to honor the aircrews who flew them. Project: 219252
