Air Force Col. Roy A. Knight, Jr., killed during the Vietnam War, was accounted for on June 4, 2019.

(Official DoD release will be updated following Primary Next of Kin briefing.)

In May 1967, Knight was a pilot with the 602nd Tactical Fighter Squadron, assigned to Udorn Royal Thai Air Base, Thailand. On May 19, 1967, Knight was the flight leader for a flight of two A-1E aircraft on a strike mission in northern Laos, when his aircraft was hit by anti-aircraft fire, severing the right wing. No parachute was observed prior to the aircraft crashing and bursting into flames. Additionally, no beeper signals were heard. While search and rescue efforts were initiated, an organized search could not be conducted due to intensity of hostile ground fire in the area. The Air Force declared Knight deceased in September 1974.
