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 chiefs meeting discussing UFOs.

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.
