What happened
USAF security police investigated lights in the forest on Dec 26; on Dec 28 Lt. Col. Charles Halt led a patrol and recorded 18 minutes of audio in real time.
Every case in this series leaves documents. Rendlesham left a voice. In the last days of December 1980, security police at the twin USAF bases of Woodbridge and Bentwaters went into the forest after lights came down in the trees — and when the lights returned two nights later, the deputy base commander went in himself with a microcassette recorder running.
This episode plays the real tape — labeled on screen, excerpted unedited — as a career officer's procedural log bends, minute by minute, into "this is weird." The skeptics' file gets full strength: the Orfordness lighthouse on the exact sightline, the Boxing Day fireball, and the parts of the story that grew decades later.

Multiple USAF security police (Penniston, Burroughs, Cabansag); Deputy Base Cmdr. Lt. Col. Charles Halt on tape.
Halt's memo to the UK MoD ("Unexplained Lights", Jan 13, 1981, released 1983) — never retracted — and the tape itself, a U.S. government recording in the public domain.
MoD: "no defence significance." The memo stands; the tape is undisputed.
Five miles away, the Orfordness lighthouse flashed on the airmen's sightline roughly every five seconds; a brilliant fireball crossed England as the first reports began; a forester matched the ground marks to rabbit diggings; and Penniston's binary-code account surfaced three decades late. The lighthouse explains a light. It has always struggled to explain a craft described at arm's length by trained security police who had walked that forest for months. Both readings survive the tape — that is rare, and the episode says so plainly.
