London, June 21 : Hundreds of people have come up with UFO sighting claims following recent reports that a British police helicopter crew chased a mystery craft in Cardiff.
Many say that they saw the UFO on the same night when the three-man crew chased it.
One Dawn Williams said that she feared an Independence Day-style alien invasion when she saw an unusual object in the sky above Aberdare Country Park on June 8.
"It came over the horizon and was travelling for about a minute and a half before it disappeared," British tabloid The Sun quoted the 45-year-old woman.
"It was circular and had a dome on top - it looked like a planet with rings. I didn't say anything at the time because I didn't think anyone would believe me," she added.
Cabaret duo Katy Cunnion and Russell Quinn say that a weird light in the sky followed them an hour after the helicopter scare.
"It was hovering. At first I thought it was a helicopter, but every time I changed direction it was in the same place. It disappeared, then I got a bit freaked out when the light came back close enough for us to see it was saucer-shaped with lights which flashed from one to another in a chain. It looked like no plane or aircraft I had ever seen," said Katy.
It finally zoomed off "like a shooting star" after an hour, added Katy.
The description of the UFO coming from Katy was very similar to the one given by the helicopter cops.
David Coggins, an expert who has studied UFOs for about three decades, said: "I'm told that in the past three months airline pilots have been reporting at least two or three encounters a week with UFOs over the Bristol Channel. Many of them will have rational explanations, but the probability is around 15 to 20 per cent can't be identified."
The Ministry of Defence, which investigates UFO sightings, said it was still awaiting the police report on the helicopter incident.
