The truth is out there – the CIA is offering a peek into its ‘X-files,’ shining a spotlight on a series of once-classified UFO documents.

“To help navigate the vast amount of data contained in our FOIA UFO collection, we’ve decided to highlight a few documents both skeptics and believers will find interesting,” explained the agency, in a blog post.

The UFO documents, which date primarily from the 1940s and 1950s, are among hundreds that the CIA declassified in 1978.

In a nod to Fox’s new “X-Files” series, the agency highlights “five documents we think X-Files character Agent Fox Mulder would love to use to try and persuade others of the existence of extraterrestrial activity.”

“We also pulled five documents we think his skeptical partner, Agent Dana Scully, could use to prove there is a scientific explanation for UFO sightings,” it added.

The “Mulder” documents include 1952 reports of flying saucers over the then-East Germany, Spain and North Africa, as well as a survey of UFO reports from the same year. The agency also posted a 1952 report of “two fiery disks” flying over a uranium mine in the then-Belgian Congo and the minutes of a CIA branch chief’s meeting discussing UFOs.

The report from East Germany details “an object ‘resembling a huge frying pan’ and having a diameter of about 15 meters [49 feet].” The object landed in a forest clearing in Germany’s Soviet Zone, according to the report.

“A smoke-trailing object over Barcelona” and an unusual object “emitting a pale green light” over the Tunisian city of Sousse are described in the report from Spain and North Africa.

Photos posted on the CIA website include an unexplained sighting above Minneapolis in 1960 and another above Sheffield, U.K. two years later. It also posted an image of a UFO investigation in Socorro, N.M.

The “Mulder” documents include an office memo from 1949, a 1952 memo to the Director of Central Intelligence and a ‘Memorandum for the Record on Flying Saucers,’ also from 1952. The agency also posted a 1953 document detailing the suggestions of a scientific advisory panel on UFOs and the minutes of an Office of Scientific Intelligence (OSI) UFO advisory group from the same year.
