In the early hours of 26th February 2016, multiple witnesses in and around the village of Pentyrch in South Wales describe seeing a vast triangular UFO appearing in the night sky. They all then reported seeing it engage in a battle with the British Airforce, culminating in the UFOs apparent shooting down. Numerous local residents also describe shaking buildings, violent explosions, inexplicably damaged trees and mysterious teams of unknown people involved in a clandestine clean up. If this extraordinary event is proved to be extra-terrestrial it would stake it's claim as the one of most significant UFO international event in history, on a par with the famous Roswell event of 1947.

For the first time - it's official UFOs are real. As UFOs move from conspiracy theory to receiving top level government approval - an extraordinary new ten-part series launches on Sky History investigating some of the world's most jaw-dropping and recent unexplained UFO sightings. Our hosts, Craig Charles and Sarah Cruddas, will turn to world renowned UFO experts, whistle-blowers and first hand eye-witnesses to build their cases!
