A U.S. Air Force pilot training class poses before an A-1 Skyraider, identified here as "Express 32," class 67-05. Among them is Maj. Roy A. Knight Jr., shot down over Laos on May 19, 1967, while flying a rescue-support mission. Declared missing for decades, his remains were finally identified and returned home in 2019 — a reminder of the lasting human cost carried by families of the missing. Project: 218839
