Declassification

The truth really IS out there: CIA releases thousands of declassified 'X-files' on aliens, flying saucers and other unexplained phenomena

The CIA has released thousands of declassified documents on flying saucers, aliens and other unexplained phenomena. 

'We've decided to highlight a few documents both skeptics and believers will find interesting,' the agency said on its website.

The post continued: 'Below you will find 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.'

All of the documents are dated from the late 1940s to the 1960s, but were top-secret until now.
