Are UFOs Flying Above Us?

A History Channel docuseries is even making skeptics do a double take.

Video shot by U.S. fighter pilots on a training mission off the coast of Jacksonville, Florida, is making even skeptics do a double take.

Pilots recently reported seeing mysterious objects that could reach "hypersonic speeds" and still turn on a dime.

The New York Times even reported on the sighting, something generally reserved for tabloids. The newspaper giant published a story five days ago with the headline: “'Wow, What Is That?' Navy Pilots Report Unexplained Flying Objects.” 

The video is part of a six-part History Channel series called “Unidentified: Inside America's UFO Investigation," which premieres Friday at 10 p.m.

Christopher Mellon, former deputy assistant secretary of defense for intelligence, spoke to Inside Edition about the unidentified flying objects. 

“It's utterly baffling, actually,” he said. “They easily outmaneuver our front-line combat aircraft and sometimes accelerate away at thousands of miles an hour, speed that would rip apart an F-35 or an F-22 and kill the pilot. We have no idea how this is being achieved.” 

He said “we all want to know” what the objects in the sky are but he insisted they aren't necessarily from outer space

“I'd like to remind everybody unidentified flying object doesn't mean alien spaceship. We have to keep an open mind, we really need desperately is more information,” he said. “Might be the Russians and Chinese, could be private industry somewhere.

"They all seem low probability and yet the facts are the facts.”
