OK here is the newspaper article from nick Poe that mentions this picture , and the fact that he says his Boss took down the Photo in his office. https://www.thescottishsun.co.uk/news/6144270/ufo-sighting-cavine-scotland-aliens-ministry-of-defence/ . Then we have an article about the original negatives being lost by the MOD (its a good read) 'Best' UFO Picture Ever, the Calvine Photo, Found After 30 Years MissingOne of my favorite UFO pictures. Ask Nick Pope if this is one of the pictures that was taken down from his office while he worked at the MOD
. The we have the FOI (Freedom of information request) asking about the photos, is more information used to be available a MOD In the Nick Pope article he summarizes a meeting he and his boss had " Summing up, the intelligence officer ran through the possibilities. Gesturing to the left with his finger, he said the object in the photograph wasn’t Russian. Jerking his hand to the right, he said it wasn’t American. He looked at us intently and said that only left one other possibility.
He pointed straight up. My boss and I couldn’t help looking up too. Then we looked at each other and then we looked back at the intelligence officer. His face was inscrutable." However in the second link about recovering an original photo the journalist says "Sadly, I do not think that mysterious aircraft arrived from another galaxy," Clarke wrote in a piece he published in the Daily Mail. "I believe it was man-made somewhere in a secret hangar—and whatever it was remains on the secret list and highly sensitive." Sorry to have not fully closed this mystery but I know that Nicks office had the picture taken down as I was not that far away.
