Rendlesham Forest — USAF Base Incursion, UK

The Rendlesham Forest incident, documented in a formal memorandum from USAF Deputy Base Commander Lt. Col. Charles Halt to the UK Ministry of Defence, describes a structured non-terrestrial object that entered the airspace of an active NATO nuclear weapons storage facility over three consecutive nights. On December 26, 1980, USAF security personnel observed a craft land in Rendlesham Forest adjacent to the base; they described a triangular metallic object with blue and white lights. Ground indentations, broken branches, and radiation readings three times background level were measured and recorded. On December 28, Lt. Col. Halt personally led a team into the forest to investigate and recorded the entire event on audio tape. His recording captures him describing a moving light source that beamed down into the nuclear weapons storage area. Halt's official memorandum to the UK Ministry of Defence, released under FOIA, states the object 'manoeuvred through the trees and disappeared.' A 2026 DoD archive release includes previously classified NSA signals intelligence intercepts from the nights in question, with the content partially redacted, and a DIA routing note marked 'EYES ONLY' that acknowledges the event.
