Footage from 2015 of a mysterious object flying over the Atlantic Ocean was revealed this week. “The sensational two-minute clip, shot on an infra-red camera, captures the moment military personnel aboard a US Navy F/A 18 jet flying at 25,000 feet spotted the bizarre craft,” reports the Sun UK.

“What the f— is that thing?” shouted the pilot in the video posted online by the To the Stars Academy of Arts and Science, a private research company.

The video was shot off the East Coast in 2015. To the Stars Academy did not say how it obtained the declassified footage, but said others could obtain it through a Freedom of Information Act request.

Christopher Mellon, who served as deputy assistant secretary of defense for intelligence in the Clinton and George W. Bush administrations, believes the object could be evidence not of a UFO, but rather of being “technologically leap-frogged by Russia or China.”

Mellon also contends the footage might “be evidence of some alien civilization.”

“Unfortunately, we have no idea, because we aren’t even seeking answers.”
