Rendlesham Forest: The UFO Encounter a USAF Commander Caught on Tape
When the lights came back, the deputy base commander walked into the forest with a Geiger counter and a running microcassette recorder. Eighteen minutes survive. You hear them in this episode.
The short answer
- 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.
- Who reported it
- Multiple USAF security police (Penniston, Burroughs, Cabansag); Deputy Base Cmdr. Lt. Col. Charles Halt on tape.
- What the record holds
- 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.
- Official status
- MoD: "no defence significance." The memo stands; the tape is undisputed.
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.

In the last days of December, 1980, something came down in an English forest between two military airbases operated by the United States Air Force. We know this case differently than every other case in this series — because when the deputy base commander walked into those trees to investigate, he brought a microcassette recorder. And he left it running. What you are about to hear, throughout this episode, is that recording — made by a United States Air Force lieutenant colonel, on duty, in real time.
[Authentic Halt tape excerpt — U.S. Air Force recording, Dec 28, 1980]
This is UAP Press. We don't tell you what to believe. We show you the record — the witnesses on the record, the documents the governments released, and, this time, the audio the record kept — and let the file speak for itself.
RAF Woodbridge and RAF Bentwaters sit a few miles apart in Suffolk, on England's east coast — twin bases, British names, but in 1980 home to the United States Air Force's 81st Tactical Fighter Wing, and long reported — though never officially confirmed — to hold nuclear weapons. Between the two bases lies Rendlesham Forest: miles of planted pine, dark and ruler-straight.
Around three in the morning on December 26th — Boxing Day — security police at Woodbridge's East Gate saw lights descending into the forest. The first thought was reasonable: an aircraft had gone down. Three patrolmen were sent into the trees to check — among them Staff Sergeant Jim Penniston and Airman First Class John Burroughs.
What Penniston reported finding was not wreckage. His account — logged, sketched, and repeated for four decades — describes a small triangular craft resting in a clearing, roughly three meters across, its surface smooth and warm to the touch, marked with raised symbols he copied into his notebook. Burroughs, nearby, described the clearing filled with light and the air thick with static.
And then, in their telling, it rose through the trees and was gone. Local police, called out, found only the beam of a distant lighthouse. But in daylight, the airmen found three indentations in the frozen ground, pressed in a triangle — and days later, higher radiation readings at those marks than in the surrounding soil. Hold every piece of that; the skeptics' file will want each one.
Under normal procedure, that would have been the end: an odd report, an unofficial shrug. What made Rendlesham permanent is that the deputy base commander, Lieutenant Colonel Charles Halt, put it on paper. His memorandum to the British Ministry of Defence — subject line: "Unexplained Lights" — is one page long, dry as a manifest, and it is real. You are looking at it now.
The memo did something almost unheard of: it entered the file through the front door. When it surfaced through the Freedom of Information Act three years later, it did so on official letterhead with a lieutenant colonel's signature — a document no one could call a rumor. The British press called the case "Britain's Roswell." The name stuck, but notice the difference: Roswell has a retraction at its center. Rendlesham has a memo that was never withdrawn.
Two nights after the first encounter, the lights came back — and this time Halt went into the forest himself, with a security detail, a Geiger counter, and the recorder. Eighteen minutes survive. Listen to how it begins: not with wonder — with procedure. A career officer, logging readings.
[Authentic Halt tape excerpt — U.S. Air Force recording, Dec 28, 1980]
Minutes in, the procedure starts to bend. The men see a red light through the trees — moving, breaking apart, throwing off glowing fragments. Halt's voice stays level, but the intervals between his words get shorter. Whatever is out there is not holding still.
[Authentic Halt tape excerpt — U.S. Air Force recording, Dec 28, 1980]
"This is weird." Sit with who is saying that, and where. A lieutenant colonel of the United States Air Force, deputy commander of a nuclear-capable installation, on duty, on tape, telling his own recorder that what he is watching defies him. Halt would later state that beams from the objects came down inside the base perimeter — near the weapons storage area. That last claim is his testimony, made repeatedly, including in a notarized affidavit in 2010. The tape itself is fact. What it captures is the question.
Now the counter-reading — and Rendlesham's is one of the best in the literature. Five miles from those trees stands the Orfordness lighthouse. From inside the forest, on the sightline the airmen walked, its beam pulsed roughly every five seconds — low, bright, and, to men who did not know it was there, moving. This is it, in daylight. Skeptics note the flashing light on the tape recurs at intervals uncannily close to five seconds.
The file continues: a brilliant fireball crossed southern England at almost exactly the moment the first lights were reported — a plausible trigger for the "crash." The indentations, a forester said, matched rabbit diggings. The radiation readings sat within the instrument's margin for background. And the accounts grew: Penniston's notebook is period; his account of receiving binary code from the craft surfaced three decades later, and we treat it accordingly — as a later addition, not part of the 1980 record.
That is a real explanation, assembled from real parts — lighthouse, meteor, rabbits, memory. And here is what it must carry: trained security police, on a base they patrolled every night of their working lives, who had walked that forest and seen that lighthouse for months — mistaking it, at close range, for a landed craft with a hull warm to the touch. The lighthouse explains a light. It has always struggled to explain the clearing.
The Rendlesham file holds the season's strangest inventory: a signed memo no one retracted, eighteen minutes of an officer's voice the Air Force never disputed, witnesses who never recanted — and a lighthouse standing exactly where the skeptics say it stands. Both readings survive the tape. That is rare, and worth saying plainly.
Charles Halt retired a colonel and spent forty years repeating, under oath and on stages, the same sentence: he believes what his men saw was not of this world. The Ministry of Defence closed its file with the words "no defence significance." Between the colonel's affidavit and the ministry's shrug sits everything this series is about.
Every case in this season has lived downstream of one story — the crash that taught the world the words "flying saucer," the file every government answer has been measured against since 1947. Next time, we open the original. And we are going to do something with it that this niche almost never does: read the record honestly, including the parts that have an explanation. Roswell. That's the next case file. Subscribe so you don't miss it. This is UAP Press. The file stays open.

The skeptics' file
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.
What's explained, what isn't
Has an explanation on the record
- A flashing light on the sightline: the Orfordness lighthouse, about five miles off, flashed roughly every five seconds, close to the interval on the tape.
- A plausible trigger: a bright fireball crossed southern England as the first reports began.
- The ground marks: a forester matched the indentations to rabbit diggings.
- The radiation readings: they sat within the instrument's margin for background.
Still open
- A craft described at arm's length, smooth and warm to the touch, by trained security police who had walked that forest and seen that lighthouse for months.
- The objects Halt describes on tape moving, breaking apart and throwing off glowing fragments, and the beams he later testified came down inside the base.
- Why a deputy base commander put his name to a memo he never withdrew.
Questions people ask
What happened at Rendlesham Forest?
Over two nights in December 1980, U.S. Air Force security police at RAF Woodbridge and RAF Bentwaters in Suffolk investigated lights in the forest between the bases. On the second night the deputy base commander, Lt. Col. Charles Halt, led a patrol and recorded about 18 minutes of audio in real time. His memo to the UK Ministry of Defence, "Unexplained Lights", was released in 1983 and never retracted.
Is the Halt tape real?
Yes. It's Lt. Col. Halt's own recording, made on duty on 28 December 1980. It's a U.S. government work in the public domain, and the Air Force has never disputed it. What the tape captures, what the lights were, is the open question.
Was it just the Orfordness lighthouse?
It's the strongest explanation on the record. The lighthouse, about five miles away, flashed on the airmen's sightline roughly every five seconds. It explains a flashing light. It has always struggled to explain a craft described at close range by security police who knew the forest.
What did the Ministry of Defence conclude?
The UK Ministry of Defence said the events were of "no defence significance." Halt's memo still stands, and the tape is undisputed.
When did the binary code story appear?
Jim Penniston's notebook dates from 1980. His account of receiving binary code from the craft surfaced about three decades later. UAP Press treats it as later testimony, not part of the 1980 record.
