The Pentagon has released more declassified UFO documents, including an eyewitness account detailing how the military recovered the wreckage of a spaceship and alien bodies.

The report made public on Friday included testimony from a military officer, whose name was redacted, who claimed he was present at the famous Roswell UFO incident in 1947 and was shown the spacecraft in a hangar known as ‘Building 84’.

‘I am convinced that what I personally observed was some type of craft and its crew from outer space,’ the witness said in a statement given in 2002 and kept secret by the Pentagon.
