As The Mirror reported, the hikers handed the photo negatives to Scotland's Daily Record newspaper — which then sent them to the British Ministry of Defense. At that point, the photographs disappeared. The Ministry of Defense say that they returned them to the Daily Record, but the Daily Record says they never received them and they have no idea what happened to them. Now, however, thanks to journalist David Clarke's determination, one of the Calvine photographs has been rediscovered 32 years after it was taken. Do you believe UFO's exist?

While the discovery and recovery of the photo have been a major breakthrough for UFO research, the identities of the hikers who took this photo — as well as the five others — remain unknown. Per Newsweek, the two men had been working as chefs in a hotel in Pitlochry, in the Scottish Highlands. On that fateful evening in August, they decided to go for a walk in the hills near Calvine, whereupon they saw the UFO moving silently through the air. "They saw this thing in the sky and it scared them," Clarke said. "They ran into some woodland to sort of keep their heads down, and they heard this jet come down the valley and then, two minutes later, it returned and started circling around the object. And that's when they took the photographs." Have you ever seen a UFO?

"Sadly, I do not think that mysterious aircraft arrived from another galaxy," Clarke wrote in a piece for 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." What do you think it is?

Do you believe aliens have contacted us here on Earth?
