Frederick C. Marr

Master Sergeant, United States Air Force

Master Sergeant Frederick C. Marr served with the United States Air Force at RAF Lakenheath during the famous radar/visual incident of August 13–14, 1956. As the senior radar controller on duty, Marr was among the first personnel to recognize that the radar returns being observed were unlike conventional aircraft.

Throughout the night, Marr and fellow radar operators tracked multiple unidentified targets displaying remarkable flight characteristics. The objects reportedly accelerated rapidly, executed abrupt turns, stopped suddenly, and at times appeared to hover before resuming high-speed flight. These maneuvers were observed on more than one radar system, reducing the likelihood of equipment malfunction.

When a Royal Air Force Venom night fighter was scrambled to investigate one of the targets, Marr coordinated with radar operators as the interceptor approached the object. According to official reports, the unidentified target appeared to maneuver behind the Venom, seemingly following it for several minutes before accelerating away at high speed.

Marr documented the incident through official military reporting channels, and his observations became a significant part of the subsequent Project Blue Book investigation. Because his testimony was supported by multiple radar operators, visual observers, and airborne personnel, historians continue to regard his account as one of the strongest military witness testimonies associated with the Lakenheath–Bentwaters Incident.
