Two US fighter planes were scrambled¹ and ordered to shoot down an unidentified flying object (UFO) over the English countryside during the Cold War, according to secret files made public yesterday.

One pilot said he was seconds away from firing 24 rockets at the object, which moved erratically² and gave a radar³ reading like "a flying aircraft carrier".

The pilot, Milton Torres, now 77 and living in Miami, said the object spent periods motionless in the sky before reaching estimated speeds of more than 12,000 kph.

After the alert, a shadowy figure told Torres he must never talk about the incident and he duly kept silent for more than 30 years.

His story was among dozens of UFO sightings in defense⁴ ministry⁵ files released at the National Archives in London.

In a written account, Torres described how he scrambled his F-86 D Sabre jet in calm weather from the Royal Air Force base at Manston, Kent in May 1957.

"I was only a lieutenant⁶ and very much aware of the gravity of the situation. I felt very much like a one-legged man in an ass-kicking contest," he said.

"The order came to fire a salvo of rockets at the UFO. The authentication⁷ was valid⁸ and I selected 24 rockets.

"I had a lock-on that had the proportions of a flying aircraft carrier," he added. "The larger the airplane, the easier the lock-on. This blip almost locked itself."

At the last moment, the object disappeared from the radar screen and the high-speed chase was called off.

He returned to base and was debriefed⁹ the next day by an unnamed man who "looked like a well-dressed IBM salesman".

"He threatened me with a national security breach¹⁰ if I breathed a word about it to anyone," he said.

The documents contain no official explanation for the incident, which came at a time of heightened tension between the West and the Soviet¹¹ Union. Planes were on constant stand-by at British bases for a possible Soviet attack.

The files blame other UFO sightings on weather balloons, clouds or normal aircraft. Torres said he had been waiting 50 years for an explanation.

"I shall never forget it," he told the Times newspaper. "On that night I was ordered to open fire even before I had taken off. That had never happened before."

UFO expert David Clarke said the sighting may have been part of a secret US project to create phantom¹² aircraft on radar screens to test Soviet air defenses.

"Perhaps what this pilot had seen was some kind of experiment in electronic warfare¹³ or maybe it was a UFO," he said. "Something very unusual happened."
