When talking about 1950s UFOs, most people only think of Roswell and the U.S. Air Force. But on the other side of the world, in the African continent, an even stranger UFO incident occurred, backed by CIA documents—one that most UFO enthusiasts have never heard of!

In 1952, at the height of the Cold War, the U.S. and the Soviet Union were frantically building atomic bombs. A key raw material for these bombs—uranium—came largely from the Belgian Congo (present-day Democratic Republic of the Congo). It was precisely over these uranium mines that declassified CIA documents recorded glowing disc-shaped objects appearing, with a pilot even chasing them and drawing a hand-drawn flight path map!

Core Content of the CIA Report

This declassified CIA document (file number 0000015463, 4 pages) is titled “Flying Saucers Reported Over Belgian Congo Uranium Mines.” Although it was only declassified and made public in 1984 under the Freedom of Information Act (FOIA), its content is absolutely fascinating.

Sighting Details

The report records that on March 29, 1952, over the uranium mines near Elisabethville (present-day Lubumbashi), witnesses spotted two gray metallic disc-shaped objects, approximately 12 to 15 meters in diameter. The characteristics of these objects were astonishing:

• 🛸 Aluminum-colored sheen, with a hemispherical bulge in the center
• 🔥 Outer edges spinning at high speed, enveloped in a layer of flames
• 🎯 Extremely maneuverable flight path—graceful curved glides, instantaneous position changes, hovering, zigzag acceleration
• 💨 Estimated speed up to 1,500 km/h
• 🔊 Accompanied by a piercing buzzing sound

Pilot Pierre’s Personal Experience

The most convincing part of the report involves Commander Pierre, a reliable Congolese military pilot at Elisabethville Airport, who personally scrambled a fighter jet to intercept!

Commander Pierre reported that he approached within approximately 120 meters of the objects and clearly saw:

• The disc-shaped objects were enveloped in flames, spinning rapidly
• Altitude dropped from 800-1,000 meters to just 20 meters above treetops
• He chased them for 15 minutes, and they finally accelerated away toward Lake Tanganyika

He said: “If there were people inside these things, they would have been burned to death by now.”—He concluded it was unlikely to be manned.

Hand-Drawn Diagrams in the CIA Document

What makes the document particularly valuable is that it includes hand-drawn flight path diagrams and structural sketches of the objects. These aren’t simulated images circulating online, but original hand-drawn illustrations from the scanned CIA document, detailing the objects’ appearance, structure, and flight trajectories.

These diagrams clearly show:

1. The speculated structure of the disc-shaped objects (central knob not rotating, outer rim spinning)
2. The zigzag path of the objects from stationary to accelerating away
3. The tactical maneuvers of the two objects coordinating with each other

Why Was the CIA So Concerned?

The answer is simple: Uranium.

The Shinkolobwe mine in the Belgian Congo was the world’s most important uranium source at the time; the uranium for America’s first atomic bomb came from there. During the Cold War, any unidentified flying object appearing over strategic nuclear raw materials would keep CIA top brass awake at night—what if it was a Soviet reconnaissance plane testing U.S. response? Or something beyond human technology?

The CIA classified this report as an official record, not because they believed in UFOs, but because from a national security perspective, it had to be taken seriously.

Why Is It So Obscure?

Compared to high-profile cases like Roswell or the Phoenix Lights, the CIA’s Congo uranium mine UFO incident is almost never mentioned. Possible reasons include:

• It occurred in Africa, drawing less attention from European and American UFO researchers
• The CIA’s document archive is vast, and many files haven’t been thoroughly examined
• Language barriers—the original documents are a mix of French and English

But it’s precisely this kind of “unknown hidden gem” that makes UFO research so fascinating.

Next time someone brings up Roswell, you can say: “Did you know that in 1952, over African uranium mines, the CIA personally recorded flying saucers?” That’s what real obscure UFO knowledge is all about.
