CIA releases thousands of declassified 'X-files' on aliens, flying saucers and other unexplained phenomena? IS the TRUTH HERE ?

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

One of the files attached to the post is a document from East Germany in 1952, where agents were called to investigate what witnesses described as a 'huge flying pan'.

The object was said to have a diameter of about 15 meters, according to the document.

Similar flying saucers were also spotted in North Africa and Spain, the report said.

The files also detail a case of flying saucers that were spotted over what was formerly Belgian Congo.

The document reveals that two 'fiery discs' were seen over a uranium mine, and that the discs had 'glided curves and changed position many times'.

It then adds: 'Suddenly, both discs hovered in one spot and then took off in a unique zigzag flight to the north east.

'A penetrating hissing and buzzing sound was audible to onlooker below. The whole performance lasted 10 to 12 minutes.'
