A U.S. Air Force OV-10 Bronco (serial 14619) banks over the South Vietnamese countryside. Purpose-built for the Forward Air Control (FAC) mission, the twin-boom, turboprop OV-10 could loiter at low speed over the battlefield, locate enemy positions, and mark targets with smoke rockets for strike aircraft, including A-1 Skyraiders flying close air support and search-and-rescue escort missions.
