Quick Info
February 26, 2016. Pentyrch, a small village near Cardiff, Wales. Caz Clarke and her family were outside their home when the sky above Garth Mountain came alive. A gigantic triangular craft, smaller glowing orbs, military fighter jets, helicopters, searchlights, and beams filled the night. More than 100 people saw it. Witnesses described a coordinated military operation, a craft the size of several football pitches, and strange figures on the ground. Photos, video, and audio recordings exist. Caz Clarke spent years collecting testimonies. The event remains one of the most dramatic and well-witnessed close encounters in modern British history.
February 26, 2016 – The Day Everything Changed
It was a cold Friday evening in late February. Caz Clarke was at home with her daughter and a friend. Around 8:30 p.m., Caz stepped outside to check on something in the garden. She looked up toward Garth Mountain — a local landmark that rises behind the village — and froze. The entire ridgeline was lit up with powerful beams of light sweeping back and forth. Helicopters were circling. Fighter jets roared overhead. The sky felt alive, electric.
Caz called her daughter and friend outside. Within minutes they realized this was no ordinary military exercise. A massive triangular object, dark against the night sky, was hovering above the mountain. Its size was staggering — witnesses later estimated several football pitches across. Three bright white lights sat at each corner, with a red pulsing light in the center. It made no sound. It simply hung there, motionless.
"It was enormous. The lights were so bright they lit up the whole mountain. And it just stayed there. Silent. Huge. We all just stood with our mouths open."
– Caz Clarke (initial interview, 2016)
Soon neighbors began coming out of their houses. People stood in gardens, on streets, on hillsides — more than 100 witnesses in total. Phones came out. Photos and videos were taken. The object remained visible for over an hour. Smaller glowing orbs appeared, darting around the larger craft. Fighter jets flew in formation, helicopters hovered close. Searchlights from the ground swept the sky. Beams shot downward from the triangle. It felt like a military operation — but against what?
The Craft & Orbs – What Witnesses Saw
Every witness agreed on the main object: a perfect equilateral triangle, deep black, absorbing light. Corner lights were steady white, intensely bright. A central red light pulsed slowly. The craft tilted slowly, rotated gently, but never made a sound. Smaller orbs — some red, some white, some blue-green — moved independently, zipping in straight lines, stopping abruptly, changing direction at right angles. Some witnesses counted up to 20 smaller objects.
Several people reported figures on the ground near the mountain base. Dark shapes, humanoid, moving quickly. Others saw beams of light shining down into the woods, as if searching for something. The atmosphere was thick with tension. Phones died. Car engines failed to start. Animals went silent. The experience felt overwhelming, almost otherworldly.
"I felt like we were being watched. Not just by the craft, but by something inside it. The air felt heavy. My daughter was crying. We couldn't look away."

Military Presence – Jets, Helicopters, Ground Teams
The sky was full of military aircraft. Witnesses clearly saw fast-moving fighter jets (likely Typhoons from RAF Coningsby or Lossiemouth) flying in tight formation around the triangle. Helicopters (Apache and Chinook types reported) hovered close, searchlights on. Ground vehicles — military trucks, Land Rovers — were seen moving along lanes near the mountain. Some witnesses described soldiers with rifles and night-vision gear moving through fields.
One group of witnesses near the mountain base said they saw soldiers cordoning off roads and woodland. A large black helicopter landed briefly. Beams continued to sweep the area. The entire operation felt highly coordinated, as if the military had been expecting — or tracking — the object for some time.
"The jets were screaming overhead. Helicopters were right above it. Searchlights everywhere. It looked like they were trying to force it down or surround it."

Caz Clarke – The Woman at the Center
Caz Clarke became the public face of the event. A local mother and resident, she documented everything that night: photos of the triangle, video of orbs, audio of jets and helicopters. She spent years collecting testimonies from neighbors, farmers, hikers, and even off-duty police. Her collection includes more than 100 witness statements, dozens of photos, and several videos. She created a website and appeared in interviews and documentaries. Her calm, consistent account and willingness to share evidence made her a trusted figure in the case.
Caz has always maintained the event was real, massive, and involved unknown technology. She says the experience changed her life — and the lives of everyone who saw it.
"We saw something that night that wasn't from here. It was huge, silent, and it knew we were watching. The military response was enormous. They were ready for it."
– Caz Clarke (multiple interviews, 2016–2025)
Aftermath & Ongoing Mystery
By morning the object was gone. No official statement was ever issued by the Ministry of Defence or RAF. Local police said they received no reports. The Ministry of Defence later said: "We have no record of any unusual activity." Yet the witnesses — ordinary people with no reason to lie — continue to stand by what they saw. Photos show the lights. Videos capture the sound of jets and helicopters. The Garth Mountain was lit up like a war zone for over an hour. And no one has ever provided a satisfactory explanation.
Ten years later, in 2026, the Pentyrch incident remains one of the most dramatic and best-witnessed events in modern British UFO history. Caz Clarke still collects testimonies. Witnesses still talk about that night. And the question lingers in the quiet village: what really came to Garth Mountain on February 26, 2016?
