A former Pentagon investigator who claimed to have operated a top-secret UFO program has cautioned that a significant new study on “unidentified aerial phenomena” might expose a U.S. failure, The New York Post reported.

Lue Elizondo was a former intelligence officer who worked in the shadows on sensitive national security issues, including 10 years heading up the Advanced Aerospace Threat Identification Program (AATIP), which investigates UFOs.

Since the public seeks to link UFOs to extraterrestrials, the government now refers to UAPs or Unidentified Aerial Phenomena.

Elizondo believed in the existence of mysterious phenomena after speaking with U.S. military sources who had seen UFOs, watched recordings of them, and seen photos.

Former intelligence chiefs have recently stated that UAPs are a legitimate national security threat, according to Elizondo.

“This isn’t a silly conversation,” Elizondo told reporters. “This is a conversation about someone, somewhere displaying beyond-next-generation technology in our controlled airspace, and there’s not a whole lot we can do about it. And what I would do is submit to you that if we just take the word UFO out of it, just say Russia or China has the ability to fly in our airspace unimpeded. And without detection, within minutes of taking off. That’s a real problem.”

Elizondo described vessels capable of flying at 11,000 mph, making “wild right-angle turns,” and reversing “instantly.”

“If you wanted to make a right-hand turn, it would take you about half the state of Ohio to do it,” he said of the Air Force’s SR-71 Blackbird, which has a top speed of about 2,100 mph.

The jaw-dropping craft can fly 50 feet above the Earth’s surface, 80,000 feet in the atmosphere, and even submerge underwater without sacrificing performance at any stage.

“When you see that, you recognize you are dealing with a technology more advanced than ours,” Elizondo said.

He told The Post about the truth of UFOs, the incredible things they could do, the religious biases that led federal officials to ignore their veracity, what the government knew but did not want to tell, and how UFO technology could help humanity in a series of exclusive interviews.

“They objected to UFOs as being Satanic!” confirmed Dr. Eric Davis, a former rocket scientist for the Air Force Research Laboratory, now a scientist at a government contractor, Aerospace Corporation.

Elizondo said he was once asked to stop investigating UFO by his senior official since those things were “demonic and we should not be pursuing them.”

Nick Pope, former head of the UFO office in the UK’s Ministry of Defence, saw similar incidents in the UK.

“Some objections come from people in government who think the phenomenon is real—but demonic,” said Pope. “Their belief seems to be that studying UFOs would thus give energy to attention-seeking demons, which should be avoided. This view comes, in part, from the biblical description of Satan as ‘the prince of the power of the air.’”

Secular government officials who acknowledged UFOs were then confronted with the question of what kind of action to take and who should take it.

“They can’t deal with it on a legislative basis or on a military operational basis; they can’t deal with it on the basis of a presidential policy,” said Dr. Davis. “So they let a finite group of engineers and scientists and investigators work [on it] together.”

Despite his amazing discoveries, Elizondo was still swimming against the current. He tried to persuade closed-minded nonbelievers to believe in his research, which he has compared to an “intelligence failure on the level of 9/11.”

Elizondo resigned from the Pentagon in protest of authorities’ refusal to even consider the prospect of UFOs.
