In 2016, multiple witnesses in and around the village of Pentyrch, South Wales, describe seeing a vast triangular UFO appearing in the night sky, ejecting smaller red and green craft before engaging in a battle with the British Air Force, culminating in its apparent shooting down. Residents describe shaking buildings, violent explosions, inexplicably damaged trees and mysterious teams of unknown people involved in a clandestine clean-up. The official military line was that this was merely a training exercise, but those who saw the event first-hand refuse to accept this explanation.
