14 NOVEMBER 1977 - STRUMBLE HEAD, PEMBROKESHIRE
STRUMBLE HEAD, PEMBROKESHIRE
Coastguard Tony Dalton described "a very large, brilliant, yellow-green transparent ball with a fuzzy outline, which descended from the base of a towering cloud over Garn Fawr mountain, and appeared to float down the hillside. It emitted intense light for about three seconds and there was static on the radio."
He stated that the object was as big as a bus and slowly rotated around a horizontal axis and seemed to bounce off projections on the ground. Cattle and seabirds in the vicinity became disturbed and it was this that first aroused his attention. He first of all thought it might be a UFO but a later explanation wrote it off as "ball lightning".
However this explanation doesn't fit the normal reports of ball lightning which had never exceeded about 6 inches in diameter.
