The Mystery Behind the Best UFO Picture Ever Seen

In August 1990, two hikers in Scotland captured photographs of a mysterious diamond-shaped aircraft accompanied by a Harrier jet, but the images and story were suppressed by the Ministry of Defence (MoD) for decades. Was it a prank, a hoax, an optical illusion or something else entirely? The Guardian's Daniel Lavelle reports on 'what really happened in Calvine.' Here's an excerpt: On a misty evening in August 1990, two men hiking on the moors surrounding Calvine, a pretty hamlet in Perth and Kinross, claimed to have seen a giant diamond-shaped aircraft flying above them. It apparently had no clear means of propulsion and left no smoke plume; it was silent and static, as if frozen in time. Terrified, they hit the ground and scrambled for cover behind a tree. Then a Harrier fighter jet roared into view, circling the diamond as if sizing it up for a scuffle. One of the men snapped a series of photographs just before the bizarre craft shot away vertically and disappeared.

Craig Lindsay was a press officer at the RAF base in Pitreavie Castle in Dunfermline, 50 miles away, when the Daily Record got in touch a few days later. The hikers, who worked as chefs at Fisher's Hotel in Pitlochry, had sent six photos of the diamond to the newspaper and told their story. The Record's picture editor, Andy Allen, sent Lindsay the best of the bunch. Lindsay had never seen such a clear photograph of a supposed UFO, so he forwarded the picture to the Ministry of Defence (MoD), which told him to ask the Record to send the other five photographs and their negatives. The MoD also instructed him to phone the hikers, which he did. One of them told Lindsay the whole story: the diamond, the jet, how it levitated eerily with no sound and accelerated with no obvious propellant. The MoD told Lindsay to leave the case with them. He pushed the diamond to the back of his mind.

That autumn, Lindsay attended a routine meeting in London. On his lunch break, he went for a wander around the MoD's offices and saw something familiar. 'There, on the wall in front of me, was a great big poster-size print of the best of them [the photographs]. So, I spoke to the guys that were there and I asked them what their other photographs were like.' The ministry's staff placed the other photographs on a windowsill. The snaps showed the Harrier jet moving from the right side of the frame to the left, while the diamond didn't move an inch. He quizzed some of the specialists who had investigated the photos. They told him there was no evidence of a hoax, but they didn't know what the diamond was. 'I gradually forgot all about the thing,' says Lindsay. 'Nothing had appeared from the first inquiry... I assumed that everything had just been forgotten.' The Record didn't run the story, the hikers never spoke publicly about the photos and the images weren't seen by the public for 32 years. 'It is the 35th anniversary of what has been described as the best UFO photo ever taken. Now is the time to come forward and tell us what really happened,' says Prof David Clarke, a lecturer at Sheffield Hallam University who worked as a reporter in the 1990s.
