Editing Rendlesham Forest Incident — Master Case File (section)

==== Night Three: December 27–28, 1980 (early hours of 28th) ====
Lieutenant Colonel Charles Halt personally led an investigation into the forest, bringing a team with Geiger counters, a starlight scope, and a Lanier micro-cassette recorder. Halt recorded the approximately 18-minute Halt Tape during this investigation. His team documented radiation readings at the ground impression sites, observed a flashing light in the treeline, and then observed three star-like objects in the sky that appeared to perform anomalous maneuvers before departing. Halt subsequently wrote the Halt Memo to the UK Ministry of Defence dated January 13, 1981.
