Why does the same mysterious diamond-shaped craft keep appearing across decades of UFO and UAP history? From the Calvine UFO photograph and Jonathan Reed encounter to Lockheed Skunk Works, Luis Elizondo, newly released AARO UAP footage and official Pentagon reports — the similarities are hard to ignore.
In this video, I investigate the strange history of the diamond-shaped UFO / UAP phenomenon and ask whether these sightings could be connected, secret military technology, misidentification… or something we still don't understand.
We go back to the Lockheed “Hopeless Diamond” and the beginnings of stealth aircraft technology, before examining the famous 1980 Cash-Landrum incident, the incredible 1990 Calvine UFO photograph from Scotland, and Dr Jonathan Reed's alleged 1996 black diamond / obelisk craft encounter in Washington State.
But the sightings don't stop there.
We also investigate the 2015 Pantex Nuclear Weapons Plant incident, where security personnel reported a mysterious “diamond” shaped object near one of America's most sensitive nuclear facilities, and the strange El Escorial / Chubut UFO photographs from Argentina in 2023.
Then things get even more interesting.
Officially released AARO / Pentagon UAP footage from Greece in 2024 involves a military report describing an unidentified object as “diamond-shaped” and travelling at approximately 434 knots.
Former Pentagon UAP investigator Luis Elizondo has also publicly discussed a strange wedge / diamond-shaped craft, saying this type of shape has reportedly been encountered multiple times.
And buried inside AARO's FY2025 UAP report is an extraordinary description of one of the less commonly reported UAP morphologies:
“an elongated diamond shape like two inverted pyramids.”
So why does this distinctive shape keep appearing?
Are we looking at decades of secret military aircraft and classified stealth technology?
Could some of these sightings simply be misidentifications?
Have later UFO stories been influenced by earlier cases?
Or could witnesses separated by decades genuinely be describing the same type of unexplained object?
I'm not here to tell you what to believe. Let's look at the evidence, compare the photographs, footage and official documents, and make our own minds up.
