Upcoming UFO report will be 'difficult to explain,' former national intelligence official says

A former top national intelligence official hinted that an upcoming government report on UFOs will include information that cannot easily be explained.

"There are instances where we don’t have good explanations for some of the things that we’ve seen, and when that information becomes declassified, I’ll be able to talk a little bit more about that," former Director of National Intelligence John Ratcliffe told Fox New's Maria Bartiromo on Friday.

Ratfcliffe said some UFO sightings have been declassified in the past, but a report to be released by the Pentagon and other federal agencies will present more information to the American people.

"There have been sightings all over the world," Ratcliffe said. "And when we talk about sightings, the other thing I will tell you, it’s not just a pilot or just a satellite or some intelligence collection. Usually, we have multiple sensors that are picking up these things."

Ratcliffe said elements that are hard to explain in the unreleased sightings include movements that are hard to replicate or traveling at speeds that exceed the sound barrier without creating a sonic boom.

The report is expected to be released on June 1, Bartiromo said later in the program.
