A U.S. Air Force pilot training class, identified as 'Express 37, class 67-10,' poses with their aircraft at Hurlburt Field. This photograph has been later annotated to identify each airman by name, marking several who were killed in action in Vietnam in 1967 and 1968 -- a poignant record of the sacrifices made by Air Commando aircrews during the war.
