A U.S. Air Force OV-10 Bronco taxis along an unimproved airstrip in Southeast Asia during the Vietnam War era. The twin-boom Bronco served as a Forward Air Control aircraft, marking enemy positions and directing strike aircraft such as the A-1 Skyraider 'Sandy' fighters that flew rescue and close air support missions from bases like Nakhon Phanom (NKP), Thailand and Da Nang, South Vietnam.
