A former Pentagon UFO chief has claimed that aliens are real - with “non-human” bodies previously found on earth.

According to Luis Elizondo, a long-time Defence Department researcher, he has handled “alien” technology and claims that “bodies” have been recovered from several sites. In his new book, “Imminent: Inside the Pentagon’s Hunt for UFOs,” the American makes several eyebrow raising claims.

For instance, he claims to have been told categorically the infamous Roswell incident in New Mexico in 1947 involved two flying saucers – and “four deceased non-human bodies” were recovered from the wreckage and examined.

Elizondo said: “We know where they were. We don’t know where they are. I’ve got to be careful what I say here, to not get in trouble – I still have my security clearance.” He claims other bodies have also been retrieved from subsequent sites, including Mexico in the 1950s and Kazakhstan in 1989."
