Flying saucer sightings? Reports of three-foot-tall aliens? Secret memos about suspicious objects recovered near Roswell, N.M.? They're all included in the thousands of declassified government documents posted to the FBI's new online Vault." Among the so-called "X-files" are once-classified reports dating back to the 1940s and 1950s detailing Air Force investigations into "flying discs" and the "bodies of human shape" discovered inside them. In one report from March 1950, Guy Hottel, a special agent with the FBI, said he received information from an Air Force investigator about flying saucers found in New Mexico. "They were described as being circular in shape with raised centers, approximately 50-feet in diameter," he wrote. "Each one was occupied by three bodies of human shape but only 3 feet tall, dressed in a metallic cloth of a very fine texture. Each body was bandaged in a manner very similar to the blackout suits used by speed flyers and test pilots." The informant, whose name is redacted in the file, said he thought the saucer was spotted in New Mexico because a high-powered government radar in the area interfered with the saucer's controlling mechanism. Other reports once marked "restricted" and "confidential" detail sightings of mysterious flashing lights and other "unidentified aerial objects."
