SHOCKING UFO cases you did not know about in Wales, UK

Writer's picture: Cristina GomezCristina Gomez

Deep within the rolling hills of Wales in the UK lies a remarkable history of UFOs that rivals any science fiction narrative. For over six decades, this corner of Britain has been home to some of the world’s most compelling UFO encounters, documented through official government records and multiple credible witnesses.



Police Chase with UFO over Cardiff, Wales


One of the most striking incidents occurred in 2008 near Cardiff International Airport, where a South Wales police helicopter crew had a close encounter that challenged conventional explanation. The three-man crew, described by officials as highly experienced, observed an unidentified object around midnight while awaiting clearance to land. According to police reports, the object appeared to deliberately approach the helicopter on a collision course, forcing the crew to take evasive action before it disappeared over the Bristol Channel. While the Ministry of Defense claimed no knowledge of the incident, the police maintained their conviction about the unusual nature of their encounter.


UFO Sighting at Broad Haven Primary School


Perhaps the most compelling mass sighting in Welsh UFO history took place at Broad Haven Primary School in February 1977. During their lunch break, 14 children reported witnessing a cigar-shaped spacecraft with a dome landing in a nearby field. The craft, described as silver-yellow in color and emitting orange and red flames, reportedly had a humanoid figure in a silver suit emerge from it. When the children were separately asked to draw what they had seen, their drawings showed remarkable consistency. Although the Ministry of Defense suggested the children might have misidentified a yellow sewage tank, the witnesses, now adults, stand by their account of that day.

The same year brought another extraordinary encounter at the Wylfa nuclear power station. A former Royal Marine, working as an engineer at the facility, reported a bizarre incident involving a turquoise light that entered his room and settled on an armchair. The light, described as perfectly controlled and containing pinpoint lights resembling stars, appeared to have a skin-like surface and pulsated with energy before vanishing through a window, all while producing no heat or sound.

The Welsh Roswell

Wales even has its own “Roswell” incident. In January 1974, the Berwyn Mountains became the center of attention when claims emerged about the recovery of alien bodies and spacecraft wreckage. The case gained renewed interest when a Channel 5 production company approached the Ministry of Defense seeking information about the alleged incident, though official responses remain elusive.

Pentyrch UFO Sighting

More recently, in February 2016, a controversial case unfolded in Pentyrch near Cardiff. During the early hours of February 26th, at approximately 2 AM, Clarke and her neighbor Dave witnessed what they described as a massive pyramid-shaped craft adorned with distinctive red and green lights hovering in the night sky. According to their account, the craft exhibited highly unusual behavior, performing pendulum-like movements before reportedly launching green objects from its apex.

The incident took an even more dramatic turn when the craft allegedly crashed in the Smilog Forest, leaving behind a trail of peculiar evidence including mysteriously whitened and damaged trees. What makes this case particularly compelling was the subsequent military response, which included multiple helicopters (notably a damaged Apache) and personnel dressed in forensic suits conducting extensive ground searches. While military officials attempted to dismiss the activity as part of “Exercise Chameleon,” a routine training operation, Clarke’s experience went beyond the initial sighting. She reported several anomalous phenomena in the aftermath, including unexplained phone battery drainage, apparent telepathic communications, and bizarre localized spongy snowfall in the area.

Perhaps most intriguingly, Clarke claims she was subjected to intimidation tactics and pressured to maintain silence about the incident for 18 months following her experience. The credibility of her testimony is bolstered by her successful completion of polygraph tests, though skeptics continue to suggest alternative explanations, attributing the lights to parachute flares and the tree damage to natural causes.


In 2009, the UK Ministry of Defense officially shut down its UFO investigation unit, claiming it served no defense purpose. However, the wealth of documented cases, particularly those involving military and law enforcement personnel, continues to raise questions about the true nature of these encounters. While some sightings have conventional explanations, such as Chinese lanterns, others remain unexplained, adding to Wales’s reputation as a hotspot for unexplained aerial phenomena.

Today, while some of these UFO files are available in the National Archives, many others remain classified, leading to ongoing speculation about what other encounters might still be hidden from public view. The Welsh UFO files represent a fascinating chapter in the study of unexplained aerial phenomena, combining credible witnesses, official documentation, and incidents that continue to challenge our understanding of what’s possible in our skies.
