Lue Elizondo, formerly from the secretive Advanced Aerospace Threat Identification Program (AATIP), claims to have seen the UFO footage. He describes it as showing unidentified floating objects for 23 minutes.
“The video was extremely compelling – one of many – to the point where I remember getting some expertise to look at it,” Mr Elizondo told YouTube channel Fade to Black.
“I did not say what it was.
“I sent it out to some highly trained experts in the ISR (Intelligence, surveillance, and reconnaissance) community.
“And when they came back to me, the title of the email was quote unquote ‘that UFO video’.”

He also said he hopes the footage will be released to the public so “everybody can see it for themselves”.
He teased that “there are other ones which are equally compelling”.
It follows the release of a long-anticipated UFO report last month.
Released on the website of the Office of the Director for National Intelligence, it shared 144 reports of what the US government classified as UFO encounters.
“Of the 144 reports we are dealing with here, we have no clear indications that there is any non-terrestrial explanation for them — but we will go wherever the data takes us,” a senior US official said.
