Douglas A-1 Skyraider taxiing, Southeast Asia, circa November 1970. Wings folded to clear the crowded revetments, a camouflaged Skyraider moves along the taxiway of a large air base, with the airfield's hangars and a distant mountain range behind. The A-1's manually folding outer wing panels were a legacy of its origins as a carrier aircraft and proved equally useful on congested wartime airfields. Photographed by Donald L. Engebretsen, a U.S. Air Force A-1 pilot with Operating Location Alpha Alpha at Da Nang, whose Skyraiders flew close air support for MACV-SOG reconnaissance teams and stood 'Sandy' alert for the rescue of downed aircrew.
