Secret CIA files reveal UFOs were intercepted by jet fighters over nuclear base only for them to ‘fly off into space’

CIA documents detail the extraordinary moment US fighter jets chased two UFOs over a nuclear base before the objects flew off into space.

The formerly secret files, released under a freedom of information request, say the mysterious objects were spotted by members of the public in November 1975.

Locals near Malmstrom Air Force Base in Montana – the site of numerous UFO sightings – reported seeing “lights in the sky and the sounds of jet engines similar to jet fighters.”

But officials from the base said “no jet aircraft” were spotted within 100 nautical miles of the UFO sighting.

Two F-106 jets were scrambled to intercept the UFOs sparking a chase reaching speeds of up to 172mph (150 knots).

The documents state: “0253 EST Malmstrom AFB Montana received seven radar cuts on the height-finder radar at altitudes between 9,500′ and 15,000′.

“Simultaneously, ground witnesses observed lights in the sky and the sounds of ket engines similar ti jet fighters.

“Cross-tell with FFA revealed no jet aircraft within 100NM of the sightings.

“Objects could not be intercepted. Fighters had to maintain a minimum of 12,000′ (feet) because of mountainous terrain.

“Sightings had turned west, increased sped of 150 knots.”

Witnesses said the UFOs turn off their lights during the chase which then came back on after the fighter jets returned to base, according to the CIA files.

“0420 EST – Personnel at 4 SAC sites reported observing intercepting F-106’s arrive in area; sighted objects turned off their lights upon arrival of interceptors, and back on upon their departure,” the docs said.

Officials said weather services confirmed “no possibility of Northern Lights” being the cause of the darting objects in the sky.

The documents finish by saying one of the UFOs was seen flying off into space.

“At 0405, SAC Site L-5 observed one object accelerate and climb rapidly to a point in altitude where it became indistinguishable from the stars.”

A spokesman for The Black Vault, a site which hosting millions of the US government’s declassified files, said the incident in Montana is one of many.

He told The Sun Online: “The 1975 Malmstrom case was only one, of quite a few, that chronicled UFOs over sensitive military bases and nuclear weapon storage facilities, all which had no plausible explanation.”

“Flying over these types of bases with no way to be intercepted and no identification, is by definition a ‘national security threat.’ It is secured airspace for a reason, and when encroached upon, the US military should be able to take care of the problem with the best tools in their arsenal.

“The problem was – they couldn’t. They couldn’t catch it, identify it, or get rid of whatever problem it was.

“For decades, the US military wanted the public to believe they were ignoring such cases, or that they did not even exist. However, through legal means with the use of the US Freedom of Information Act (FOIA), we know better.”

Another alleged UFO encounter at Malmstrom on March 24, 1967 resulted in a raft of nuclear missiles being deactivated.

Former Air Force officer Robert Salas, who was the on-duty commander of an underground launch control facility, claims all ten of his intercontinental ballistic missiles became inoperable.

But Captain Salas said the simultaneous shutdown was an “impossible” occurrence because the ten nuclear Minuteman rockets were all running on independent systems.

The “attack” implied a level of sophistication that no human at the time possessed, he says.

Salas said: “I can only speculate as to why it happened. I think it was simply a message to all of us on Planet Earth that we need to rid ourselves of nuclear weapons.”
