The Mainbrace Sightings
Sept 1952


Capt. Ed Ruppelt:
"It was these sightings, I was told by an RAF exchange intelligence officer in the Pentagon, that caused the RAF to officially recognize the UFO."

Ruppelt's account:
In late September 1952 the NATO naval forces had held maneuvers off the coast of Europe; they were called Operation Mainbrace. Before they had started someone in the Pentagon had half seriously mentioned that Naval Intelligence should keep an eye open for UFO's, but no one really expected the UFO's to show up. Nevertheless, once again the UFO's were their old unpredictable selves - they were there.

On September 20, a U.S. newspaper reporter aboard an aircraft carrier in the North Sea was photographing a carrier take-off in color when he happened to look back down the flight deck and saw a group of pilots and flight deck crew watching something in the sky. He went back to look and there was a silver sphere moving across the sky just behind the fleet of ships. The object appeared to be large, plenty large enough to show up in a photo, so the reporter shot several pictures. They were developed right away and turned out to be excellent. He had gotten the superstructure of the carrier in each one and, judging by the size of the object in each successive photo, one could see that it was moving rapidly.

The intelligence officers aboard the carrier studied the photos. The object looked like a balloon. From its size it was apparent that if it were a balloon, it would have been launched from one of the ships, so the word went out on the TBS radio: "Who launched a balloon?"

The answer came back on the TBS: "Nobody."

Naval Intelligence double-checked, triple-checked and quadruple-checked every ship near the carrier but they could find no one who had launched the UFO.

We kept after the Navy. The pilots and the flight deck crew who saw the UFO had mixed feelings - some were sure that the UFO was a balloon while others were just as sure that it couldn't have been. It was traveling too fast, and although it resembled a balloon in some ways it was far from being identical to the hundreds of balloons that the crew had seen the aerologists launch.

We probably wouldn't have tried so hard to get a definite answer to the Mainbrace photos if it hadn't been for the events that took place during the rest of the operation, I explained to the group of ADC officers.

The day after the photos had been taken six RAF pilots flying a formation of jet fighters over the North Sea saw something coming from the direction of the Mambrace fleet. It was a shiny, spherical object, and they couldn't recognize it as anything "friendly" so they took after it. But in a minute or two they lost it. When they neared their base, one of the pilots looked back and saw that the UFO was now following him. He turned but the UFO also turned, and again it outdistanced the Meteor in a matter of minutes.

Then on the third consecutive day a UFO showed up near the fleet, this time over Topcliffe Aerodrome in England. A pilot in a Meteor was scrambled and managed to get his jet fairly close to the UFO, close enough to see that the object was "round, silvery, and white" and seemed to "rotate around its vertical axis and sort of wobble." But before he could close in to get a really good look it was gone.
