An unidentified flying object (UFO) that was invisible to the naked eye apparently capable of being seen in footage from a police helicopter.
Police officers piloting a chopper discovered the button-shaped aerial object zipping through the air over the Bristol Channel.
Details posted along with the video revealed that the air traffic control did not detect the mysterious shape, and it was only spotted on thermal cameras.
The cops dismissed obvious suggestions as to what it could be since the UFO had a heat signature and was traveling against the wind.
A police chopper based in St. Athan, a small village in South Wales, reportedly captured the footage, which was later uploaded to its Twitter account.
Information posted to its account revealed the strange craft was discovered flying around 1000 feet up at 9:30 pm on Saturday evening.
Multiple viewers said it was a balloon or Chinese lantern, but these explanations can be ruled out with the heat and movement of the UFO.
Without obvious answers as to what the chopper just recorded on video, many suggested it was aliens.
The police Twitter account indicated that it was not a lantern as it was going into the wind. It adds that they filmed it for over seven minutes, but it ‘s hard to judge the size.
