December 26-28, 1980: US Air Force personnel stationed at RAF Bentwaters/Woodbridge (NATO joint base) encountered a landed craft in Rendlesham Forest, Suffolk, UK over three consecutive nights. Witnesses include Lt. Col. Charles Halt (Deputy Base Commander), Sgt. Jim Penniston, and Airman John Burroughs. Penniston approached and touched the craft — described as triangular, with strange symbols on the hull. He made a sketch in his notebook. Halt recorded a real-time audio tape documenting the encounter. Physical evidence: landing marks in soil, broken branches, elevated radiation readings confirmed by Geiger counter on Halt’s tape. The Halt Memo (January 13, 1981) — official US Air Force document sent to UK Ministry of Defence — is the primary document. UK MoD files now declassified. NHHC library holds Pope/Burroughs/Penniston documentation. NHHC designates it “the world’s best-documented UFO incident.” Connection to our dossier: RAF Bentwaters is a NATO nuclear weapons storage site — consistent with SCU 2026 finding that NHI specifically monitors nuclear infrastructure.
