Quick Info
On August 4, 1990, two hikers up in the Scottish Highlands near Calvine were just taking pictures of the scenery when a huge diamond-shaped craft appeared in the sky right above them. It was metallic, completely silent, and just hung there for several minutes. They managed to snap at least six clear photos. Then two RAF Harrier jets showed up and started circling it. The hikers handed the negatives straight to the United Kingdom Ministry of Defence (MoD) for analysis, expecting some kind of answer.
Instead, of course, the MoD kept everything locked away for thirty years. In 2022, Nick Pope and David Clarke finally got one of the photographs released to the public. It's widely considered one of the clearest and most credible UFO images ever captured, showing a craft that doesn't match any known aircraft, hovering in broad daylight while jets fly around it like they're trying to figure it out too.
Timeline of Events – August 4, 1990
Reconstructed from the witnesses' statements, MoD documents, Nick Pope's account, David Clarke's research, and the 2022 public release.
- Afternoon, August 4, 1990 Two hikers (one named Craig, the other still anonymous) are walking in the hills near Calvine, Perth and Kinross, Scotland. They're carrying a camera, probably a 35mm SLR, and stop to take landscape shots.
- Sighting begins A large diamond-shaped metallic object suddenly appears in the sky above them. It's silent, motionless, and reflects the sunlight sharply. They estimate it's around 100 feet across with a smooth, seamless surface and no visible propulsion. They start snapping photographs as the craft just hovers there.
- Harrier jets arrive Two RAF Harrier jump jets appear and begin circling the object at close range. The diamond craft stays completely still while the jets maneuver around it. The hikers keep taking pictures, capturing at least six frames that show the craft and the jets together.
- Departure After several minutes, the diamond object accelerates away at high speed and disappears. The Harrier jets either follow or peel off shortly after. The hikers are left stunned but excited by what they've just seen and photographed.
- Post-sighting The two men develop the film and take the negatives to the Ministry of Defence, probably through a local RAF base or direct submission. They're told the MoD will analyze the images and get back to them. They never hear anything again. The negatives stay in MoD hands.
- 1990 to 2022 The photographs remain classified. The witnesses hear nothing. Rumors spread quietly in UFO circles, but no images ever surface. The case becomes known as "the best UFO photo never released."
- August 2022 After thirty years, one photograph is finally released to the public by Nick Pope (former MoD UFO desk officer) and David Clarke (UFO researcher). The image shows the diamond craft clearly, with a Harrier jet in the frame for scale. No official explanation is given. The other five photos remain classified or missing.
What the Witnesses Described
The two hikers gave very consistent accounts. The object was diamond-shaped (like a rhombus or kite when viewed from below), metallic, silver-gray, completely seamless, and made no sound at all. It hovered motionless for several minutes, reflecting the daylight sharply. When the two Harrier jets arrived, the craft didn't react aggressively or try to flee, it simply stayed in place while the jets circled around it. After a while it accelerated away extremely fast and was gone.
"It was diamond-shaped, metallic, completely silent. It just hung there in the sky. When the Harriers showed up, it didn't move away or attack, it just stayed. We took pictures, handed them over, and never heard another word."
– Craig (one of the hikers, anonymous interview after 2022 release)
The hikers were excited but also a bit unnerved, which is completely understandable given the event they just witnessed. They submitted the film expecting answers, but instead the MoD took the negatives and never got back to them. Craig later said he felt the government knew exactly what it was and simply didn't want anyone else to see it.
Who Is Craig Lindsay? The RAF Press Officer Who Held the Photo for 32 Years
Craig Lindsay is not one of the two hikers who took the photographs, he’s the retired RAF press officer who ended up with one of the original prints for over three decades. In 1990, the Daily Record newspaper sent him a set of the Calvine photos along with the contact details of one of the witnesses. Lindsay was working at RAF Pitreavie Castle in Scotland at the time, and he became the Ministry of Defence’s first point of contact for the case.
"I’ve been waiting for someone to call me about this for 30 years! The witness told me it made no noise at all. That made me take it seriously, nothing we had could do that in daylight and stay silent."
– Craig Lindsay (to David Clarke, 2021–2022 interviews)
He looked at the images, spoke briefly with the witness on the phone, and immediately realized this was different from the usual UFO reports that crossed his desk (blurry lights or distant shapes). The witness told him the craft made no noise at all, which really stood out, no known aircraft in 1990 could hover silently in daylight like that. Craig made photocopies, faxed them to the MoD UFO desk in London, and kept one first-generation print safe, along with the original envelope. He waited for follow-up that never came. The MoD took the negatives and said nothing more.
For 32 years, Craig held onto that print quietly. He never sold it, never leaked it, never tried to make money from it. In 2021, UFO researcher David Clarke finally tracked him down. Craig told Clarke: “I’ve been waiting for someone to call me about this for 30 years!” Clarke visited him in Calvine, interviewed him in person, and Craig handed over the original print, envelope, and photocopies to Sheffield Hallam University’s Special Collections for safekeeping.
"I kept the print safe all these years. The MoD took the negatives and never gave them back or explained anything. I always thought it was something real and secret, but I never heard another word until David Clarke found me."
– Craig Lindsay (2022 interview at RAF Pitreavie Castle)
On June 27, 2022, Clarke and Vinnie Adams interviewed Craig again at RAF Pitreavie Castle, the same base where he first handled the photos. Craig officially donated the materials that day. In interviews (Daily Record, Daily Mail, James Fox’s *The Program* behind-the-scenes clips, and others), Craig has always said the photo is genuine and not hoaxed. He believes the object was real, human-made, and highly secret, possibly an early stealth blimp or Aurora spy plane prototype, but he’s adamant it wasn’t extraterrestrial. He also confirmed the MoD’s silence was unusual even by their standards. He’s now in his mid-80s and has spoken openly because he feels the public deserves to see what he saw back in 1990.
His role is crucial: without Craig keeping that print safe and eventually sharing it with Clarke, the Calvine photo might still be locked away, or lost forever. He’s not a UFO believer, but he’s a credible, no-nonsense witness who handled the evidence firsthand and waited decades for someone to ask him about it. That quiet integrity makes his part of the story just as powerful as the original sighting itself.
The Calvine Photograph (Released 2022)
The single publicly released photo shows a large diamond-shaped object in clear daylight, sharply defined against the sky, with a Harrier jet in the frame for scale. The craft looks metallic, seamless, and unusually geometric, with no wings, tail, or conventional aircraft features. Size estimates from the photo and witness statements put it at 80 to 120 feet across. There's no heat distortion, no blur, and no signs of hoaxing like double exposure or models.
Experts have analyzed the image and found no evidence of tampering or any known aircraft that matches it. The other five photographs (showing different angles, closer jet passes, or the craft departing) are still classified or missing. The MoD has never explained why they held the images for thirty years or what their analysis concluded.

The Official Response & Investigation
The UK Ministry of Defence took the negatives and said they would analyze them. The hikers were told nothing further. The case was quietly filed away. Nick Pope, who ran the MoD UFO desk in the 1990s, later confirmed the photos were real and highly unusual, no conventional explanation fit. David Clarke, a UFO researcher, obtained the one photo in 2022 through persistent FOIA requests.
The MoD's official line remains vague: "no defense significance." No radar data or jet pilot reports have been released. The incident is one of the few cases where actual photographs were handed directly to a government agency and then suppressed for three decades.
Legacy in 2026
Over thirty-five years later, the Calvine photographs remain one of the clearest and most credible pieces of UAP evidence ever captured. A diamond-shaped craft, larger than any known aircraft, hovers silently in daylight over Scotland while RAF Harrier jets circle it, and the images are held secret for thirty years. The 2022 release reignited global interest: no hoax evidence, no matching aircraft, no explanation. I even seen one "debunker" claim the UFO was nothing more than a reflection of water... what water? And since when do RAF fighter jets circle a reflection in the sky?
In 2026, with UFO/UAP disclosures forcing governments to acknowledge anomalous phenomena, Calvine is seen as a cornerstone case, photographic proof of something non-human operating in our airspace. The fact that the MoD kept the best images hidden for so long only strengthens the belief that they know exactly what it was, and don't want us to know. And, perhaps most important of all, exactly where are the other 5 photographs?
