Many people have tried to follow-up with the FBI about the alleged confirmation of Alien life, but the FBI hasn’t released anything else. Some have even taken to scouring thousands of other released FBI documents to connect the dots. The FBI continues to play it cool, however, saying
“The FBI has only occasionally been involved in investigating reports of UFOs and extraterrestrials. For a few years after the Roswell incident, Director Hoover did order his agents—at the request of the Air Force—to verify any UFO sightings.
That practice ended in July 1950, four months after the Hottel memo, suggesting that our Washington Field Office didn’t think enough of that flying saucer story to look into it.”
