Larry Warren was a security officer at Bentwaters Air Force Base in the United Kingdom. He was present during an event in 1980 when an extraterrestrial vehicle landed, hovered, and interacted with Air Force personnel on base. Afterwards, the many personnel who had witnessed the events were intimidated, debriefed, and forced to sign documents telling a false version of the story. Warren's testimony is corroborated by multiple other military witnesses who have been identified. There are official documents related to this event; there is a photograph related to the event; and there is physical landing-trace evidence. This entire event is also corroborated by Ministry of Defense official Nick Pope, and five-star Admiral, Sea Lord, former Ministry of Defense head Lord Hill-Norton, and Sergeant Clifford Stone.
