Rendlesham Forest 1980: Lights, a Memorandum and a Lighthouse

7 min read

In December 1980, American servicemen reported unknown lights over two nights in a forest next to an air base in England, and the base's deputy commander was among them. The case became known as "Britain's Roswell," but according to skeptics, everyday light phenomena were misinterpreted.

When: December 1980
Where: Rendlesham Forest, Suffolk, United Kingdom
Witnesses: US Air Force security patrolmen (including Jim Penniston, John Burroughs and Ed Cabansag) and Lieutenant Colonel Charles Halt, the base's deputy commander.
Official position: According to the British Ministry of Defence, the incident posed no threat to British defense, so it was not investigated further; the Halt memorandum was forwarded to the ministry, and the file became public in 2009.

Rendlesham Forest lies in Suffolk, east of Ipswich. In 1980, two neighboring British air bases, RAF Woodbridge and RAF Bentwaters, were used by the US Air Force. According to the description of a Geograph photo, the Woodbridge base's perimeter fence runs right along the edge of the forest's pine plantations. Beyond the eastern edge of the forest, on the coast, stood the Orford Ness lighthouse, which later plays an important role in the story.

Two nights in the forest

According to the Halt memorandum, at 3 a.m. on December 27, 1980 (the document's date is one day later than the events; according to the Skeptic article, the first incident took place on December 26), two American security patrolmen saw unusual lights outside the back gate at Woodbridge. They thought an aircraft had crashed, so three patrolmen set out on foot into the trees. According to the report, they saw a metallic-looking, triangular object with red lights on top and blue lights underneath, which moved through the trees and disappeared, and the animals on a nearby farm went into a frenzy. The next day they found three depressions in the ground, and the radiation meter showed values barely above background. The following night, Lieutenant Colonel Charles Halt, the base's deputy commander, went out to the site with a few men. According to Halt's report, a red, sun-like light pulsed among the trees and then broke into five white objects, after which three star-like lights were visible in the sky, two to the north and one to the south, of which the southern one was visible for two to three hours. Halt recorded what happened on a dictation recorder, and a transcript of the recording can still be read on Ian Ridpath's site. According to Ridpath, at the start of the investigation there is no mention of the light at all; the flashing light only appears two-thirds of the way through the recording. A transcript of the recording can still be read, and it is one of the most important documents of the case.

The memorandum and "Britain's Roswell"

On January 13, 1981, Halt wrote a one-page report titled "Unexplained Lights" to the British commander, and the report also reached the British Ministry of Defence. The US Department of Defense released it in response to a Freedom of Information request, and The Black Vault received it in September 1997. For years the case was only local rumor: on October 2, 1983, the News of the World ran on its front page: "UFO LANDS IN SUFFOLK – AND THAT'S OFFICIAL!" According to the Skeptic, it was precisely the memorandum becoming public that turned the case and its witnesses into celebrities.

According to NBC News's report, the British Ministry of Defence found no evidence in connection with the Halt report that anything had intruded into British airspace and landed near Woodbridge; nothing appeared on radar, and no threat to defense was seen. The National Archives published the complete file in 2009, including a 1983 letter that proposes a combination of a fireball, the lighthouse and bright stars as an explanation. Simon Weeden, a former ministry official, told the BBC that once nothing had been found on radar and there was no obvious explanation or threat, they did not consider further action necessary.

Today the forest is a tourist attraction. The Forestry Commission created a UFO trail in 2005, and in 2014 a sculpture was erected near the supposed landing site.

The explanation: a lighthouse and the servicemen's own statements

The best-known skeptical explanation was put forward by Ian Ridpath, a British astronomy writer: the flashing light visible from the forest may have been the Orford Ness lighthouse. Vince Thurkettle, a former forestry worker, told the BBC that he found three rabbit scrapes at the supposed landing site, and he attributes the broken branches and burn marks to things common in the forest and to a forester's axe, respectively. According to him, the "landing site" is the only part of the forest from which the lighthouse can be seen, because there is a gap among the trees on Gedgrave Hill through which the light shines.

James Easton writes in the Skeptic that the servicemen's initial statements of January 2 confirm the lighthouse explanation, especially John Burroughs's affidavit. According to it, the three patrolmen, following the light, passed by a farmhouse and then, after about two miles, realized that the light was coming from a lighthouse. Easton states that Burroughs also confirmed this to him. Easton also cites the account of former security policeman Kevin Conde, who says that after Christmas 1980 he himself pulled a prank that resembles some details of the incident, although this cannot be verified from the sources available for our article, because the note breaks off here.

What remains open

The case is still not closed. Journalist and UFO historian David Clarke told the BBC that he still considers the experience of the three patrolmen on the first night unexplained. According to John Burroughs, the sighting was caused by an energy field in the forest, and the lighthouse was emitting electromagnetic frequencies toward the forest; he never claimed to have seen a spaceship. According to Brenda Butler, co-author of Sky Crash, an American or Russian experiment may have been behind it, for example the reentry of a Russian satellite. In the government file, Lord Hill-Norton, former head of the British armed forces, complained in a 1985 letter about the lack of a reassuring explanation: in his view, either British airspace is vulnerable or American personnel are capable of serious misperception. The forest itself now welcomes visitors with a UFO trail and a flying saucer replica, and on the sign of nearby Rendlesham village the landed saucer is there as well.

The sober take

A 1983 letter from the British Ministry of Defence proposed a combination of a fireball, the Orford Ness lighthouse and bright stars as an explanation, and this is supported by the analyses of Ian Ridpath and Vince Thurkettle, as well as by John Burroughs's contemporary affidavit. According to the ministry, there was no sign of an intrusion or a threat.

What was that?

A fireball in the sky? A bright meteor or reentering space debris
