The renowned Rendlesham Forest UFO encounter is once again capturing public interest due to recent assertions that a U.S. Army sergeant was given enigmatic binary messages connected to the event.

Jim Penniston, a Staff Sergeant, has consistently claimed that he encountered a peculiar code after witnessing a landed craft during the infamous 1980 incident in Rendlesham Forest, England.

Penniston asserts that the entire binary sequence he received spanned 16 pages of ones and zeros. Upon decoding, the message purportedly states: “EXPLORATION [OF] HUMANITY CONTINUOUS BEYOND 8100. EVOLUTION NOT OPTIONAL FOR PLANETARY SURVIVAL THE GREAT AWAKENING NEARS CONSCIOUSNESS MUST EXPAND OR THE CHAIN FRACTURES.”

The message continues: “… WE RETURNED TO WARN FROM WHERE YOU WILL BE IF YOU CHOOSE THE PATH ORIGIN YEAR 8100 RETURN COORDINATES SEALED IN ANCIENT STONES ADVANCE OR PERISH THE CHOICE IS NOW.”

The incident took place in December 1980, near the RAF Bentwaters and RAF Woodbridge air bases in Suffolk, which were utilized by the U.S. Air Force during the Cold War.

Penniston, a US Air Force security policeman stationed at the base, said he approached the object and examined it at close range, describing it as triangular and metallic, with a surface unlike any known aircraft. 

He later recalled: ‘I estimated it to be about nine feet tall and about nine feet wide at the base. 

‘No landing gear was apparent, but it seemed like she was on fixed legs. I moved a little closer… I walked around the craft, and finally, I walked right up to the craft. I noticed the fabric of the shell was more like a smooth, opaque, black glass.’

How the event was reported at the time

Often called ‘Britain’s Roswell,’ the incident remains one of the most documented and controversial UFO cases ever recorded. 

At the time, multiple US military personnel reported seeing strange lights moving through the forest. Unlike most UFO sightings, witnesses did not describe a distant object in the sky; they said the craft landed. 

Several senior officers recorded their observations on audio tape, creating an official record that still exists today.

Another key witness, then–Deputy Base Commander Colonel Charles Halt, later described the encounter in a memo that became one of the most cited documents in UFO history. 

‘While in Rendlesham Forest, our security team observed a light that looked like a large eye, red in color, moving through the trees,’ Halt wrote. ‘After a few minutes, this object began dripping something that looked like molten metal.’

The case gained further notoriety years later when Penniston claimed that the encounter did not end in the forest. He said that long after the incident, he somehow received a stream of binary code connected to the craft. Penniston produced 16 pages filled with handwritten ones and zeros, claiming the information was transmitted to him mentally.

When decoded, believers say the binary text translates into English phrases that include ‘Exploration of Humanity’ and ‘Origin Year 8100,’ along with geographic coordinates that appear to point to ancient sites around the world. 

Some interpret this as evidence that the craft’s occupants were not aliens, but time travelers, possibly humans from the distant future returning to observe or warn their ancestors.

The location itself has only deepened the mystery. RAF Bentwaters reportedly housed tactical nuclear weapons during the Cold War, according to Robert Hastings’ book UFOs and Nukes.

Hastings alleges that another unidentified craft was once seen hovering above a weapons storage area at the base, fueling theories that UFOs may be drawn to nuclear technology.

Skeptics, however, have offered far more mundane explanations. Some argue that the supposed landing marks in the forest were nothing more than rabbit holes, and that flashing lights could have been explained by nearby lighthouses or military activity. 

Others have suggested that stress, darkness, and expectation played a role in shaping what witnesses believed they saw.

Now, filmmaker Mark Christopher Lee said he experienced a remarkably similar phenomenon while investigating the site for his documentary. 

Lee, who describes himself as a skeptic with a science background, claimed he later visualized binary code that translated into an ominous warning about humanity’s survival. 

Together, the accounts have reignited debate over whether the Rendlesham encounter involved extraterrestrials, time travelers, or classified Cold War technology. 

Lee, director of 45 Years Later: Rendlesham, Britain’s Roswell, said he once shared those doubts, particularly regarding Penniston’s binary code claims. But that changed after he spent a night filming in Rendlesham Forest.

He told Daily Mail that during filming, his crew encountered unexplained electronic disturbances and strange visual phenomena. 

‘Whilst filming, we did manifest a weird electronic noise that was coming from the woods, the EMF reader we had was also peaking, there was definitely something in the woods interacting with us. We tried to find the source of the sound, but it kept changing directions. We would also see orbs of light flashing,’ he said.

Lee, who said he approaches paranormal claims cautiously, said he was unable to find a conventional explanation. ‘I always try to debunk stuff as I have a science degree, but I couldn’t see any natural reason for the phenomenon we all experienced,’ he said. 

‘This has made me a firm believer in something weird that happened and is still happening at Rendlesham Forest since 1980. 

‘Was it due to alleged secret weapons testing using EMP, which may have ripped open a portal to other dimensions or time? It sounds crazy, but the only other alternative is that future humans came back in a craft to give Pennington this apocalyptic warning?’

Lee believes the incident may not have been extraterrestrial at all, but rather tied to classified Cold War experiments conducted in the region. He pointed to nearby facilities such as Orford Ness and Martlesham Heath, which were known for radar and weapons research.

But Lee said the most unsettling moment came after filming had ended. According to him, he returned to his hotel exhausted and unable to sleep when something unexpected happened.

‘I came back after a long day filming, and I was just lying in bed unable to sleep, and all I could see were ones and zeros in front of me. I thought initially I was just tired, but I’ve never had anything like that before,’ he said.

‘We also never covered the Penniston Binary Code in the days of filming, so it wasn’t on my mind at all.’

Lee claimed he wrote down the sequence he visualized and later had it translated into English, resulting in the same message the US sergeant had received.
