The Calvine UFO Photograph (1990)
On August 4, 1990, two hikers on the moors above Calvine, Scotland, spotted a huge diamond-shaped craft hovering motionless about 30 metres above the ground. They took six photographs before a Harrier fighter jet appeared and seemed to circle the object, which then shot straight up and vanished. The negatives, handed to the UK Ministry of Defence, disappeared for over thirty years.

Why it endures
A photograph considered by many experts to be the best UFO picture ever taken — so much so that the British government pushed its declassification back to 2072.
Official version (contested)
The Ministry of Defence never confirmed the object's nature nor explained the disappearance of the original negatives, only partially recovered in 2022.
