A man who hacked into US military computers to find proof of UFOs has slammed NASA's latest claims they have found no evidence of aliens - saying: "They will never tell us the truth."

Gary McKinnon, 57, was accused of the "biggest military computer hack of all time" by US officials after he gained access to US Army, Navy, Air Force, Pentagon, and NASA computers 21 years ago.

He claimed at the time he found a photo of an alien spacecraft on NASA computers - and has now hit out after the agency's UAP report published last week, which found no evidence of extra-terrestrial life

Dubbing NASA the "National Association of Space Actors", McKinnon told The U.S. Sun: "As usual, they said nothing, on balance. 

"And when pressed they just repeated their non-committal statement.

"We'll never get any truth from military institutions, which NASA is, regardless of the fact that it pretends to be a civilian institution."
