UFOs: The Porton Down Affair

UFOs: The Porton Down Affair | Mysterious Universe: "On the night of January 23, 1974, an enigmatic and unresolved event occurred on the Berwyn Mountains range in North Wales, United Kingdom that, for some within the UFO research community, has come to be known as the definitive British Roswell. Researcher Andy Roberts stated of this mysterious affair (in his book, UFO Down!): “The claim was that a UFO piloted by extraterrestrials crashed, or was shot down, on the mountain known as Cader Berwyn and that the alien crew, some still alive, were whisked off to a secret military installation in the south of England for study.”"
