Description: Large diamond shape UFO hovering for about 10 minutes before ascending vertically upwards at high speed. During sighting RAF aircraft, believed to be a Harrier fighter jet made a number of low level passes for 5 or 6 minutes before disappearing off.

I see the image you uploaded. Here’s a breakdown of what’s in it:
The photo appears to be an older, slightly faded color print.
In the sky, there are two main objects:
One is a diamond-shaped object (appearing flat, with a metallic or uniform surface). It is centered in the frame and stands out strongly.
Below and to the right, there is a smaller airplane (likely a jet or small aircraft), flying at some distance from the diamond-shaped object.
The background shows a cloudy sky with low contrast lighting, suggesting it might be overcast.
At the bottom of the image, you can see parts of a fence with barbed wire and some vegetation, placing the scene at ground level looking upward.
There are also tree branches at the top edge of the photo, framing the scene.
This photo is often associated with UFO reports because of the diamond-shaped aerial object. It’s sometimes referred to as the “Calvine UFO photograph,” reportedly taken in Scotland in 1990.
Would you like me to focus more on a technical image analysis (shapes, scale, perspective, possible explanations) or on the historical context of this specific photograph?
Historical Context
This photo is widely known as one of the “Calvine UFO” photographs, taken in Scotland in August 1990 by two hikers.
They claimed to see a large diamond-shaped craft hovering in the sky for about 10 minutes, with military jets circling it.
The original negatives were reportedly handed to a Scottish newspaper, which then passed them to the UK Ministry of Defence. The images were classified for decades.
Only one scan resurfaced publicly (the one you’ve uploaded), sparking debates among UFO researchers, skeptics, and aviation enthusiasts.
Step 1: Relative Size in the Photo
Looking at the image:
The diamond-shaped object spans about 5–6 times the apparent length of the plane’s fuselage in the picture.
The plane looks quite small, suggesting it’s much farther back in the scene compared to the diamond object (otherwise the size discrepancy would be even more extreme).
Step 2: Baseline Aircraft Dimensions
If the plane is a typical UK fighter jet of the early 1990s (like a Tornado F3 interceptor):
Length ≈ 16–20 meters (52–66 ft)
Wingspan ≈ 13 meters (43 ft)
Step 3: Estimating the Diamond Object
If the plane was actually circling behind or near the object (not miles further away), and the proportion seen in the photo reflects something close to reality:
The diamond craft would measure on the order of 80–100 meters (260–330 ft) across at its longest point.
That’s larger than a Boeing 747’s wingspan (~68 meters), putting it into the category of very large aircraft or an aerial structure.
Step 4: Caveats
If the diamond was much closer to the camera than the plane, then the apparent size is exaggerated. For example, it could be a small object (like a model) only a few meters wide, photographed in the foreground.
The lack of depth cues (cloud contrast, shadows) makes it impossible to determine exact scale from the photo alone.
✅ Bottom line:
If the plane and diamond were genuinely at comparable distances from the camera, the diamond-shaped object would have been massive (80–100m wide) — far larger than any known jet at the time. But if the photo was staged with forced perspective, the object could have been just a few feet wide.
