Eleven Air Force Skyraider pilots of the 'Express 28' flight pose before their A-1 aircraft, tail number 906, marked for its rescue-escort role. Two of the men pictured, Capt. Darrell J. Spinler and Lt. Col. Joseph L. Hart, were later killed in action in 1967. A-1 Skyraider pilots, often called 'Sandys,' flew perilous low-altitude missions escorting rescue helicopters to recover downed airmen throughout the Vietnam War. Project: 218839
