A former Army Sergeant, Clifford Stone, has said the US Government had tried to suppress what he actually seen one strange day in Pennsylvania, back in 1969.
"I was involved in situations where we actually did recoveries of crashed saucers. There were bodies that were involved with some of these crashes. Also some of these were alive," he said. "While we were doing this, we were telling the American public there was nothing to it. We were telling the world there was nothing to it," Mr Stone added.
"You have individuals that look very much like you and myself, that could walk among us and you wouldn't even notice the difference," he said.
Stone claimed to have catalogued 57 different species of alien life forms.
We met Clifford Stone at the Roswell Museum in New Mexico where he was kind enough to grant us several hours of his time. After listening to him for only a short while, it became clear we were in the presence of a very extraordinary man.
This soft-spoken gentleman has an astounding tale to tell about his alien friend, Korona; how he went on crash recovery missions in Vietnam during the 60s; how he helped an ET to escape from military custody.
He's got a massive heart and a broad perspective that manages to capture the whole world in its sights. He talks of the rights of the visitors to our planet in the face of captivity; he talks of their sense of sacrifice for the well being of humanity. He speaks of the need for us to care what happens to the 'other guy', and how real feeling for each other is what's going to make the difference as we move forward to join the galactic community.
