Sixteen Air Force officers of training class 'Express 18' pose before a T-28 Trojan at Hurlburt Field. Within months, three of these men — Capt Robert I. Bush, Capt Robert L. Sandner, and Capt Theodore J. Shorack Jr. — were killed in action in Vietnam within days of each other in June 1966. This photograph stands as a memorial to the shared training and shared sacrifice of an Air Commando pilot class. Project: 218839
