The Halt Tape

A colonel's live audio as the lights moved through the trees. "It's dead ahead."

The Halt Tape: a real-time audio recording made by Deputy Base Commander Lt. Col. Charles Halt during the December 1980 Rendlesham Forest incident outside RAF Bentwaters — airmen tracking moving lights, radiation readings called out, voices audibly shaken. Documented: the tape, Halt's official memo to the UK Ministry of Defence ('Unexplained Lights,' released 1983), and radiation measurements the MoD later called consistent with background. The tape's power is procedural: it is the sound of the security state failing to explain something to itself.
