LONDON (AP) – The deputy commander of a U.S. Air Force base in England was baffled by what he’d seen: bright, pulsing lights in the night sky.

Britain’s defense ministry couldn’t explain it either, but concluded that the unidentified flying object posed no threat.

The National Archives on Aug. 17 released the government’s complete file on the “Rendlesham Forest Incident” of December 1980, one of Britain’s most famous UFO sightings.

It was among more than 4,000 pages posted online documenting 800 alleged encounters during the 1980s and 1990s. Over the past three years the Ministry of Defense has been gradually releasing previously secret UFO papers after facing Freedom of Information demands.


The Rendlesham file contains U.S. Air Force Lt. Col. Charles Halt’s first-hand account of the event, which has been public knowledge for many years. The file includes the conclusions of a British government investigation and a letter from a former defense chief urging officials to take UFOs more seriously.

Lt. Col. Halt reported that two servicemen had noticed “unusual lights” about 3 a.m. in the woods outside the gates of RAF Woodbridge, a U.S. base in eastern England. He wrote that patrolmen sent to investigate saw “a strange glowing object” in the forest.

The metallic, triangular object “illuminated the entire forest with a white light,” he wrote.

The next day, investigators found depressions in the ground and unusual radiation readings. That night many personnel–including Lt. Col. Halt himself–saw a pulsing “red sun-like light” in the trees that broke into five white objects and disappeared.

The Ministry of Defense could offer no definitive explanation for what the Air Force officers had reported seeing, but also found no evidence of “any threat to the defense of the United Kingdom.”

Nothing had registered on radar, and “there was no evidence of anything having intruded into U.K. airspace and landed near RAF Woodbridge.”

A 1983 letter in the file proposes a possible explanation involving a combination of the nearby Orford Ness lighthouse, a fireball and bright stars.

Case closed, as far as the ministry was concerned. But not everyone was convinced.

A 1985 letter from Lord Hill-Norton, former head of Britain’s armed forces, to then-Defense Secretary Michael Heseltine, complained that the “puzzling and disquieting” episode had never been explained properly.

Lord Hill-Norton said if the sighting was genuine, “British airspace and territory are vulnerable to unwarranted intrusion to a disturbing degree.” The alternative explanation was that “a sizable number of USAF personnel at an important base in British territory are capable of serious misperception, the consequences of which might be grave in military terms.”

Britain’s defense ministry has charted UFO sightings since the 1950s, when a Flying Saucer Working Party was established. More files are due to be released by the archives through 2010.

Some of the newly-released events came with easy explanations.

In 1993 and 1994, the ministry received numerous reports of a “brightly illuminated oval object” over London. It turned out to be an airship advertising a new car.

More mysterious was a UFO “attack” on a cemetery in Widnes, northwest England, in July 1996. A police report said a young man–“a sensible sort of lad and genuine”–reported seeing a UFO firing beams of light into the ground.

A police officer sent to the scene found a smoldering railway sleeper. “It does look rather odd,” reported the officer, whose name was blacked out in the document.

The files include a little grist for conspiracy theorists.

The head of the ministry’s UFO desk wrote briefing notes in 1993 reporting a spate of sightings in southwest England and speculating whether they might be connected to Aurora, a secret U.S. spy plane whose existence has never been officially admitted.

Atop one of his letters, someone scrawled: “Thank you. I suggest you now drop this subject.”

The files reveal a 1996 spike in UFO sightings: 609 that year, up from 117 the year before.

David Clarke, a UFO historian and consultant to the National Archives, said it was probably no coincidence that the supernatural TV show “The X Files” was popular in Britain at the time, and that alien-invasion movie “Independence Day” came out the same year.

“It’s evident there is some connection between newspaper stories, TV programs and films about alien visitors, and the numbers of UFO sightings,” Mr. Clarke said.

“Aside from 1996, one of the busiest years for UFO sightings reported to the MoD (Ministry of Defense) over the past half century was 1978–the year ‘Close Encounters of the Third Kind’ was released.”

But recent reports of UFOs and strange bright lights continued Aug. 13 with sightings of orange lights showing up at night in East Anglia. The mysteries and the government disclosures came as Britons have reported a record number of the sightings to the military so far this year.

According the Ministry of Defense, a record 231 UFO sightings have been called in since the beginning of the year. The numbers have climbed steadily upward with 285 sightings in 2008, 135 sighting in 2007 and 97 sightings in 2006.

Over the past three years MUFON, which tracks and investigates reports of unidentified flying objects, has seen triple the number of average reported sightings, James Carrion, of the Montreal UFO Network, said. The 500-600 reports a month doesn’t mean more activity, but there is more public awareness and more news coverage that has made UFOs a popular subject, he explained.

Freedom of Information acts, and similar laws, in the United Kingdom and the United States, have helped government agencies decide to take pro-active approaches and release some information, instead of being inundated with requests, Mr. Carrion pointed out.

With British, French, and Chilean government agencies releasing information, for example, public awareness is increased and public reporting increases, he continued. It doesn’t mean governments are more open, just that public interest is handled in a strategic way, Mr. Carrion argued.

“Given that they know what is flying around their skies–but the government saying there is nothing to it, but we know that there is, government doesn’t state what they know. There is a cover-up of information,” he said.
