An A-1 Skyraider attack aircraft sits on a rain-slicked airfield ramp with its engine turning, photographed at dusk or dawn during the Vietnam War. The illuminated navigation lights and blurred propeller disc indicate the aircraft was preparing for or returning from a low-light sortie. Air Commando and Air Force Skyraider squadrons routinely flew missions at first and last light in support of ground troops and search-and-rescue operations across Southeast Asia. Project: 218950
