Early hours of 26 and 28 December 1980; memorandum 13 January 1981 / T149
Rendlesham Forest: separate the nights, memo and later additions
Rendlesham Forest, near RAF Woodbridge and RAF Bentwaters, Suffolk

Witness account
U.S. Air Force personnel reported unusual lights near RAF Woodbridge during the early hours of 26 December. Charles Halt led a later visit in the early hours of 28 December and recorded observations of lights and radiation-meter readings. His memorandum to the British Ministry of Defence, dated 13 January 1981, instead gave 27 and 29 December, creating a persistent one-day error in later timelines.
Public record
The case includes a real official memorandum, Halt’s audio recording and police attendance. Suffolk police reported the lighthouse as the light they could see and considered ground impressions potentially animal-made. These sources document an unusual experience and the investigation, while the interpretation of the lights, impressions and meter readings remains contested.
