U.S. Air Force aircrew share a lighthearted moment on the flight line at a Southeast Asia airbase during the Vietnam War era. The floral wrap worn by the airman at center reflects a common squadron tradition of marking a crew member's completed combat tour or milestone mission with playful hazing rituals. Behind them, corrugated-steel revetments -- built to shield parked aircraft from rocket and mortar attack -- underscore the operational realities of wartime airfields in the region. Project: 219603
