Mark Pilkington, an expert on the unexplained, has made the shocking claims after researching the UFO phenomena.
The British author claims the strange craft sighted around the world really do exist – but they are not aliens.
Flying saucers and unidentified aircraft are actually secret technology being developed by the US, he claims.
Mr Pilkington claimed a shadowy organisation he dubbed “mirage men” were behind a global double bluff.
He has produced a new documentary of the same name he boasted exposes the truth behind UFOs.
