# The Rendlesham Forest Incident: Britain’s Roswell

In December 1980, United States Air Force personnel stationed at RAF Woodbridge in Suffolk, England, reported a series of encounters with unidentified lights and a metallic triangular object in the adjacent Rendlesham Forest. The incident, which unfolded over at least two nights near two of NATO’s most strategically significant military bases, produced an official memo from the deputy base commander, physical traces on the ground, radiation readings, and a real-time audio recording. It remains the most extensively documented alleged UFO event in British history and has drawn comparisons to the 1947 Roswell incident in the United States.

TL;DR: Over two nights in late December 1980, USAF security personnel at RAF Woodbridge reported seeing strange lights and a metallic triangular object in Rendlesham Forest. Deputy base commander Lt Col Charles Halt documented the events in an official memo to the UK Ministry of Defence and made a real-time tape recording during the second night’s investigation. Physical traces including ground depressions and elevated radiation readings were recorded at the site. Skeptics attribute the sightings to a combination of a bright meteor, the Orford Ness lighthouse, and bright stars. The UK Ministry of Defence concluded the incident posed no threat to national security. No definitive explanation has been officially established. Sources linked below.

Colonel Charles Halt, the deputy base commander at RAF Woodbridge, describes what he witnessed during the December 1980 Rendlesham Forest incident in this interview with 7 News Spotlight.

Timeline

  • December 26, 1980, approximately 03:00 GMT: Security patrol near the east gate of RAF Woodbridge observes lights apparently descending into Rendlesham Forest. Three patrolmen enter the forest to investigate what they believe may be a downed aircraft.
  • December 26, 1980, approximately 04:00: Suffolk Constabulary officers respond to a call from the base. They report seeing only the Orford Ness lighthouse and find nothing unusual.
  • December 26, 1980, morning: Servicemen return to the forest and discover three triangular depressions in the ground, broken branches, and apparent scorch marks on nearby trees.
  • December 26, 1980, 10:30: Local police are called again to inspect the ground markings. Officers attribute the indentations to animals.
  • December 28, 1980, early hours: Lt Col Charles Halt leads a team into the forest to investigate. He records events on a micro-cassette recorder. Radiation readings are taken, a flashing light is observed, and star-like objects are reported in the sky.
  • January 13, 1981: Halt writes an official memo titled “Unexplained Lights” addressed to the UK Ministry of Defence, documenting the events of both nights.
  • June 1983: The Halt memo is released to the public under the US Freedom of Information Act. The News of the World publishes it under the headline “UFO LANDS IN SUFFOLK, And that’s OFFICIAL.”
  • 2001: The UK Ministry of Defence releases its file on the Rendlesham incident, consisting mostly of internal correspondence and public inquiry responses.

What Happened

The Rendlesham Forest incident refers to a series of reported sightings that occurred over at least two nights in late December 1980. The events took place in and around Rendlesham Forest, a Forestry Commission plantation of approximately 5.8 square miles of coniferous woodland in Suffolk, England. The forest borders two former Royal Air Force bases, RAF Bentwaters and RAF Woodbridge, which at the time were operated by the United States Air Force and served as key NATO installations during the Cold War.

The bases housed the 81st Tactical Fighter Wing and stored tactical nuclear weapons, making them among the most strategically sensitive military sites in the Western alliance. The base commander was Colonel Ted Conrad, and his deputy was Lieutenant Colonel Charles I. Halt. The Wing Commander was Colonel Gordon E. Williams. The proximity of the reported events to nuclear-weapon storage facilities has led some researchers to draw connections between the Rendlesham incident and a broader pattern of UFO sightings near nuclear sites, a topic explored in depth by researcher Robert Hastings.

The incident began when a security patrol near the east gate of RAF Woodbridge observed unusual lights appearing to descend into the adjacent forest in the early hours of December 26, 1980. Thinking an aircraft might have crashed, the patrol requested permission to investigate. What followed became the most famous reported UFO event in British history, and one of the most extensively documented cases worldwide.

The First Night

At approximately 03:00 on December 26, 1980, a security patrol near the east gate of RAF Woodbridge noticed lights that appeared to be descending into Rendlesham Forest. The on-duty flight chief authorized three patrolmen, including Sergeant Jim Penniston and Airman John Burroughs, to proceed on foot into the forest to investigate what they suspected might be a downed aircraft.

According to the original witness statements obtained by researcher James Easton in 1997, the patrolmen entered the forest and encountered a glowing object. The original witness statements describe a variety of observations. Airman John Burroughs reported seeing a beacon light and following it for approximately two miles before realizing it was coming from a lighthouse. Ed Cabansag stated in his written account: “We figured the lights were coming from past the forest since nothing was visible when we passed through the woody forest. We would see a glowing near the beacon light, but as we got closer we found it to be a lit-up farmhouse. We got to a vantage point where we could determine that what we were chasing was only a beacon light off in the distance.”

Sergeant Jim Penniston later provided a more dramatic account. He described encountering a metallic triangular craft approximately two to three meters across, covered in hieroglyphic-like symbols. Penniston stated he touched the surface of the object and found it warm. However, as Wikipedia’s comprehensive account notes, Penniston’s claims about touching an alien spacecraft were not mentioned in any contemporaneous reports and received no corroboration from other witnesses at the time.

The patrolmen reported that the object appeared to maneuver through the trees and that animals on a nearby farm went into a frenzy. The noise was later attributed by some researchers to Muntjac deer, which are known for producing loud, shrill barking sounds when alarmed.

Shortly after 04:00, Suffolk Constabulary was called to the scene. BBC News reported that two police officers attended but found nothing unusual. In their report, the officers stated that the only lights visible were from the Orford Ness lighthouse, approximately five miles to the east. The police file on the case was later released under the UK Freedom of Information Act in 2005).

After daybreak, servicemen returned to a small clearing near the eastern edge of the forest and found three small impressions in the ground arranged in a triangular pattern. Broken branches and what appeared to be scorch marks were found on nearby trees. The local police were called again at 10:30 and, upon inspecting the markings, attributed the indentations to animal activity, possibly rabbit scrapings.

Forestry worker Vince Thurkettle, who was later interviewed about the site, told the BBC: “It was nothing. It was an absolutely normal glade in the forest with three rabbit scrapes, and they’re all carefully marked, that happened to be roughly in a triangle.”

The Second Night

In the early hours of December 28, 1980, Lt Col Halt led a team of personnel back into Rendlesham Forest to investigate the area where the ground markings had been found. Halt brought along a micro-cassette recorder and an AN/PDR-27 radiation survey meter, a standard US military device for measuring beta and gamma radiation.

Halt recorded his observations in real time as the investigation proceeded. The audio recording, which became known as the “Halt Tape,” chronicles the team’s activities including their radiation measurements, observations of flashing lights, and sightings of objects in the sky. The tape was released to UFO researchers in 1984 by Colonel Sam Morgan, who had succeeded Ted Conrad as base commander. Ian Ridpath, a science writer who has extensively analyzed the case, published a full transcript of the tape with corrections to errors found in other published versions.

During the investigation, the team measured radiation levels in the three ground depressions and the surrounding area. According to the Halt memo, beta/gamma readings of 0.1 milliroentgens were recorded, with peak readings in the three depressions and near the center of the triangle they formed. A nearby tree showed moderate readings of 0.05 to 0.07 milliroentgens on the side facing the depressions. However, readings in surrounding areas were between 0.03 and 0.04 milliroentgens, approximately at background level. The team also detected a similar small elevation more than half a mile from the presumed landing site.

As the team conducted their investigation, they observed a flashing red light across a field to the east, in the direction of a farmhouse. The Orford Ness lighthouse is located further east along the same line of sight. Later, three star-like objects were reported in the sky, two to the north and one to the south, approximately 10 degrees above the horizon. According to Halt’s account, the objects moved rapidly in sharp angular movements and displayed red, green, and blue lights. The object to the south reportedly remained visible for two to three hours and appeared to beam down a stream of light from time to time.

The Halt Memo

On January 13, 1981, nearly three weeks after the events, Lt Col Charles Halt wrote an official memorandum addressed to the UK Ministry of Defence. The memo was headed “Unexplained Lights” and was written on official US Air Force headed notepaper. Notably, it was not classified in any way.

The memo described three paragraphs of events. The first paragraph detailed the initial sighting on what Halt recorded as December 27 (now established to have been December 26), describing a “strange glowing object” that was “metallic in appearance and triangular in shape, approximately two to three meters across the base and approximately two meters high.” The object reportedly had a pulsing red light on top and banks of blue lights underneath.

The second paragraph described the ground traces found the following day and the radiation readings taken during the December 29 investigation (actually December 28). The third paragraph described the star-like objects observed in the sky and their movements.

The memo was released to the public in June 1983 under the US Freedom of Information Act by the US Air Force to Robert Todd of the pressure group Citizens Against UFO Secrecy. As Ian Ridpath’s analysis notes, the USAF had actually discarded their own copy of the memo, evidently considering it of no further interest, and had to obtain another from the British MoD before releasing it.

The memo’s release prompted the News of the World to publish its famous front-page story with the headline “UFO LANDS IN SUFFOLK, And that’s OFFICIAL.” This tabloid coverage brought the Rendlesham incident to widespread public attention for the first time.

Halt later went further than his memo. In June 2010, he signed a notarized affidavit in which he stated: “I believe the objects that I saw at close quarter were extraterrestrial in origin and that the security services of both the United States and the United Kingdom have colluded to maintain the secrecy.” However, skeptics have identified contradictions between this affidavit and the facts as recorded at the time in Halt’s original memo and tape recording.

Colonel Ted Conrad, Halt’s commanding officer, provided a statement to researcher David Clarke in 2010 that contradicted Halt’s account. Conrad stated: “We saw nothing that resembled Lieutenant Colonel Halt’s descriptions either in the sky or on the ground.” He also said: “We had people in position to validate Halt’s narrative, but none of them could.” Conrad criticized Halt’s affidavit, saying “he should be ashamed and embarrassed by his allegation that his country and Britain both conspired to deceive their citizens over this issue. He knows better.”

Physical Evidence

The physical evidence associated with the Rendlesham incident falls into three categories: ground traces, tree damage, and radiation readings.

The ground traces consisted of three small impressions arranged in a triangular pattern in a clearing near the eastern edge of Rendlesham Forest. According to the Halt memo, the depressions were approximately 1.5 inches deep and 7 inches in diameter. Witnesses described them as consistent with the landing impressions of a triangular object, with each depression at a corner of the triangle.

The tree damage included broken branches on trees surrounding the clearing and what appeared to be scorch or burn marks on the bark of some trees. Proponents of the extraterrestrial hypothesis have pointed to this damage as evidence of heat radiation from a landed craft. However, forestry worker Vince Thurkettle identified the marks as cuts made by a forestry worker named Bill Briggs with an axe, and described the broken branches as unremarkable for a pine forest.

The radiation readings taken with the AN/PDR-27 meter on the second night showed readings of 0.1 milliroentgens per hour in the depressions, which was somewhat above the background level of 0.03 to 0.04 milliroentgens per hour measured in surrounding areas. However, as skeptics have noted, the instrument used was not highly sensitive at these low levels, and a similar small elevation was detected more than half a mile away from the landing site, suggesting the readings may have been within normal environmental variation. NBC News reported that when the MoD files were released in 2009, the radiation data did not constitute evidence of anything extraordinary.

A photograph of the supposed landing site was published by Georgina Bruni in her book “You Can’t Tell the People,” taken on the morning after the first sighting. The site is now part of an official Forestry Commission UFO trail, complete with information boards and a life-size replica of the reported object.

MoD Investigation

The UK Ministry of Defence’s response to the Rendlesham incident was, by its own account, minimal. The first official to receive Halt’s memo was Simon Weeden, who worked on the MoD’s UFO desk. Dr David Clarke, a journalist and consultant to the National Archives, interviewed Weeden about the MoD’s handling of the case.

Weeden told Clarke that the memo was unusual because it came from a military source, whereas most UFO reports the MoD received were from ordinary members of the public. He circulated the memo to relevant parties, but none of the radar stations checked reported anything unusual on their logs over the Christmas holiday period. “Once we had been through all the basic checks and found there was nothing seen on radar, no obvious explanation, no obvious threat to air defence, we decided no further action was needed,” Weeden stated.

The MoD’s official position was that the incident posed no threat to the defense of the United Kingdom and was therefore never investigated as a security matter. When the MoD’s file on the incident was released in 2001, it turned out to consist primarily of internal correspondence and responses to public inquiries. The lack of any in-depth investigation in the released documents was consistent with the MoD’s stated position.

Significantly, MoD investigators never contacted the local Suffolk Constabulary regarding the incident. This meant they remained unaware of the police reports confirming that officers who attended the scene on the first night identified the observed lights as originating from the Orford Ness lighthouse. This failure to consult local police records meant that key eyewitness evidence from independent, non-military observers was never incorporated into the official assessment.

In 1985, Lord Peter Hill-Norton, a former Chief of the Defence Staff, wrote to the Defence Secretary expressing concern about the incident and asking whether the MoD had investigated it thoroughly. His inquiries contributed to growing public interest in the case, but did not result in a re-examination of the evidence.

Former MoD official Nick Pope, who was responsible for the government’s UFO desk between 1991 and 1994, has spoken extensively about the Rendlesham case. Pope co-authored the book “Encounter in Rendlesham Forest” with witnesses John Burroughs and Jim Penniston, which presents the case from the perspective of the military personnel involved. Pope has described the case as among the most significant UFO incidents in recorded history, while acknowledging that the MoD never conducted the thorough investigation that the circumstances warranted.

Skeptical Analysis

The skeptical case against the Rendlesham incident rests on the identification of several ordinary stimuli that, taken together, could account for the reported sightings. Science writer Ian Ridpath, who was the first journalist to investigate the case after it became public in 1983, has assembled the most comprehensive skeptical analysis.

Ridpath identifies five main elements that can be explained through conventional means:

The fireball: At approximately 03:00 on December 26, 1980, a bright fireball, described by the British Astronomical Association Meteor Section as “an exceptionally brilliant meteor,” burned up over southern England. This occurred at the same time the security patrol at RAF Woodbridge first noticed lights apparently descending into the forest. The fireball would have appeared to be descending directly toward the ground, consistent with the witnesses’ initial impression that an aircraft was crashing.

The lighthouse: The Orford Ness lighthouse, located approximately five miles east of the forest, was at the time one of the brightest lighthouses in the United Kingdom. Its rotating beam would have been visible through gaps in the pine trees from the location where the airmen were standing. As the witnesses moved through the forest, the lighthouse beam would have appeared to move relative to the trees, creating the impression of a light that was following or evading them. The local police who attended the scene on the first night confirmed that the only light they could see was the lighthouse.

Vince Thurkettle, a forestry worker who lived near the forest, stood in the lighthouse beam and confirmed it was clearly visible from the location of the sighting. He told the BBC that the sighting occurred in the only part of Rendlesham Forest from which the lighthouse was visible through a gap in the terrain.

Bright stars: On the second night, the “star-like objects” that Halt described hovering for hours and beaming down streams of light are consistent with bright stars viewed near the horizon, where atmospheric effects cause them to twinkle and change color. The brightest of the objects Halt described was in the direction of Sirius, the brightest star in the night sky, which can produce dramatic twinkling effects when viewed at low elevation.

Ground traces: The three depressions found at the site were identified by the attending police officers and a forestry worker as rabbit scrapings. The “scorch marks” on trees were identified as axe cuts made by a forestry worker. Broken branches are common in any pine forest.

Radiation readings: The elevated readings of 0.1 milliroentgens per hour were only slightly above background levels and within the normal range of environmental variation. The AN/PDR-27 instrument used was not highly sensitive at these low levels, and a similar reading was obtained more than half a mile from the landing site.

Ridpath notes that the concatenation of these different stimuli, all occurring on the same night, is what makes the case seem exceptional. Each element individually is commonplace, but together they created a sequence of observations that, for the unprepared witnesses, appeared to be a single extraordinary event.

Skeptics also point to the evolution of witness testimony over time. The original witness statements from the first night, unearthed by researcher James Easton in 1997, are considerably more restrained than the dramatic accounts that emerged in later years. Airman Burroughs initially stated he followed a beacon light to the lighthouse. Sergeant Penniston did not mention touching an alien spacecraft until years after the incident. Colonel Conrad confirmed that when he interviewed Penniston at the time, Penniston had not mentioned any such encounter.

Science writer Mick West, writing on Metabunk, has noted that the case illustrates how mundane stimuli can be misinterpreted as extraordinary events, especially at night when visual perception is unreliable and expectations can influence interpretation.

What Is Actually Known

After more than four decades of investigation, debate, and speculation, certain facts about the Rendlesham Forest incident can be established with reasonable confidence.

It is known that USAF security personnel at RAF Woodbridge reported seeing unusual lights on the nights of December 26 and 28, 1980. It is known that Lt Col Charles Halt wrote an official memo to the UK Ministry of Defence documenting these reports. It is known that Halt made a real-time audio recording during the second night’s investigation. It is known that ground depressions and tree damage were found at a site in the forest. And it is known that the UK Ministry of Defence concluded the incident posed no threat to national security and did not warrant further investigation.

What remains disputed is the nature of the stimulus that caused the witnesses to report what they did. The skeptical case, most comprehensively articulated by Ian Ridpath, identifies a fireball, a lighthouse, and bright stars as sufficient to explain the observations. Proponents of a more extraordinary explanation point to the number and training of the witnesses, the official memo, the radiation readings, and the physical traces as evidence that something beyond conventional misidentification occurred.

The testimony of the witnesses themselves has evolved over the decades. The original statements are more restrained than later accounts. Some key figures, including base commander Ted Conrad, have directly contradicted the more dramatic claims. Others, including Halt and Penniston, have become more emphatic over time in their assertions that they encountered something extraordinary.

As the BBC reported, Dr David Clarke, who secured the release of the MoD file, has said that the original sighting by the three USAF security guards on the first night still contains an element of mystery. “What happened to those three guys on the first night I still find baffling,” Clarke stated. “Maybe they did see something that was inexplicable.”

Writer Brenda Butler, who co-authored one of the first books on the case, has expressed the view that the full truth may never be known. “There are loads of files still to be released, but there has been such a big cover-up, nobody will ever know what happened,” she told the BBC.

Whether one finds the skeptical explanations sufficient or believes something more extraordinary occurred, the Rendlesham Forest incident remains one of the best-documented and most debated alleged UFO encounters in history. The combination of official military documentation, a real-time audio recording, multiple witnesses from a trained security force, and a paper trail through both the US and UK governments ensures that the case will continue to be studied and argued about for decades to come.

John Burroughs, one of the USAF security personnel who investigated the lights on the first night, recalls his experience in this documentary segment from UFO Conspiracies.
