Investigators believe Scot could hold important clue to one of world’s biggest UFO mysteries

Investigators believe a Scot could hold an important clue to one of the world’s biggest UFO mysteries. The “Calvine photo” taken in Perthshire in 1990 is regarded as one of the clearest UFO pictures ever taken but is at the centre of a mystery after images sent to the Ministry of Defence disappeared. But one certified copy emerged last year, showing a diamond-shaped object in the sky above Perthshire – believed by some to be the world’s “best ever UFO photo”.
