South Wales police are still scratching their heads over the UFO that appeared on one of their cameras last Saturday, reports the Daily Mail in Britain.
Officers flying in a helicopter across the Bristol Channel around 9:30 p.m. local time became aware of the mystery object when it showed up on the aircraft’s thermal camera. It was not visible to the eye, nor did air-traffic control detect the unidentified object.
The helicopter’s altitude at the time was 1,000 feet.
“It’s difficult to judge the size but we filmed it for just over seven minutes,” the police tweeted, while requesting suggestions from the public as to the object’s identity.
