Interesting stuff :-
"In 1958 author Gavin Gibbons wrote By Space Ship to the Moon, a sci-fi book which featured a UFO landing on the Berwyn mountains in Wales. Sixteen
years later, in 1974, those same mountains would again be the focus for a story involving a downed UFO."
Night of the Actual Incident
"Just after 8.30pm thousands of people in the area were jolted from their winter musings by at least one, possibly two, explosions, followed
immediately by a terrible rumbling. The whole event lasted four or five seconds. Furniture moved, ornaments rattled, buildings shook. Livestock and
domestic animals voiced their terror. As people shot to their windows some saw lights streaking across the sky. Villagers flooded out into the streets
in an attempt to discover the cause of the violent disturbance. As they looked up into the mountains several saw a mysterious white glow, lasting a
few seconds. Others saw beams of light being projected into the night sky"
Official reaction was quick to the initial explosion.
"Suspiciously quick some say, with more police and military arriving within minutes, turning people away from the mountain roads. In the days
following it seems there was an unusual and large military presence in the area. Roads remained closed and farmers reported they were forbidden from
tending their stock. Something was obviously being sought, or why would military jets and helicopters be criss-crossing the area and strangers combing
the mountainsides? Scientists from university departments also came to tramp the hills, but far more suspicious were the official-looking outsiders
who turned up in the villages immediately after the event, tight-lipped about their business but keenly interested in the events on the mountain"
"There is a report that an Army vehicle was seen coming down the mountain near Bala Lake with a large square box on the back of it and accompanied by
outriders"
Later on.......
"In 1980, an electronics engineer named Arthur Adams, who had worked on Concorde, visited the Berwyn UFO crash-site and found strange green coloured
pieces of metal embedded in the rocks there. He took samples of the metal to his laboratory and discovered that a sample the size of a 1-inch cube
gave off two kilowatts of electricity, when wired up to a volt meter"
Arthur Adams later in life
"Arthur's Stumbled on the secret of free electricity
There's more than a welcome in the Welsh hillsides, according to specialist metal prospector Arthur Adams.
He reckons there could be a fortune in "magic" metal deposits -- similar to the chunk he's gouged out of a gold bearing mountain just off the
Mawddach Estuary, North Wales.
But so far, his accidental find -- a silver grey metal which he claims gives off electrical energy -- has brought cynicism and disbelief from mineral
scientists and a warning under the Official Secrets Act.
In fact, to prove his point, he already claims to run clocks, a radio, and a small TV set at his home -- just by plugging into his piece of strange
metal.
Mr Adams, a retired ultra-sonic engineer and radiologist who once worked on Concorde, patented his discovery under a trade name. But the Ministry of
Defence warned him in writing that his find was covered by the Official Secrets Acts.
He was not to reveal the components of the substance or it's location."
I am sure I will find more on this as I keep digging.
