We already knew that and now the news is spreading throughout the corporate media as well. See the brief article published on the website of the American magazine Newsweek: the existence of UFOs "was proven without a shadow of a doubt," according to the head of the secret program of the Pentagon, who analyzed the mysterious aircraft. In an interview with the British newspaper the Telegraph published on Saturday (23), Luis Elizondo told the newspaper about the sightings:

In my opinion, if this were a court of law, we reached the point of "proof without a doubt". I hate to use the term UFO, but that's what we're seeing. I think it's pretty clear that it's not us, and it's no one else, so no one needs to ask where they're from.

Elizondo led the U.S. Department of Defense's advanced Aerospace Threat Identification program, investigating evidence of UFO and extraterrestrial life, from 2007 to 2012, when the program was closed. Its existence was first reported by the New York Times the week before last. Elizondo failed to discuss details of the program. But he told the Telegraph that there were "many" UFO sightings and witnesses interviewed during the five years of the program. The researchers identified geographical "hot spots" that were sometimes close to nuclear installations and power plants. They also observed trends among aircraft, including lack of flight surfaces in objects and extreme maneuverability, Elizondo told the Telegraph. He said:

There was never a display of hostility, but the way they maneuvered, in ways that no one else had in the world, you have to be aware that something could happen.

Although the Pentagon's funding was depleted in 2012, Elizondo oversaw the UFO work for another five years before resigning in October 2017 in frustration with the secret of investigations. He had pressed for the videos of possible alien sightings to be released, so that people could see the footage. In his letter of resignation to the Secretary of Defense, Jim Mattis, Elizondo asked:

Why aren't we spending more time and effort on this issue? There is a vital need to determine the capacity and intent of these phenomena for the benefit of the armed forces and the nation.

Elizondo told the Telegraph that he would like to see someone assemble the research project again?

I'd say, reopen the program. We want NASA to find life on different planets, but we have highly trained pilots here, and they're seeing something they can't understand.

Source Yes, the phenomenon of UFOs exists without a shadow of a doubt, and after all these proofs that have been made public-not only as the latter of the Pentagon itself, but also those of politicians, military, astronauts, government agents, etc. – Throughout all these years, who does not believe in it, or is working with those who want to cover up the phenomenon, or is a great fool of mind blocked due to false dogmas of religious or scientific character. The real question now to be resolved by obtaining concrete evidence is: who are they and what do they want? Some say they already have the answer.
