Luis Elizondo [was the] director of the [Pentagon's] Advanced Aerospace Threat Identification Programme (AATIP). He claims to have been told categorically by senior fellow researchers that the notorious Roswell incident in New Mexico in 1947 really did involve a UAP crash, perhaps involving two flying saucers " and that "four deceased non-human bodies" were recovered from the wreckage and examined. Asked what happened to these supposed bodies, he says on our video call: "We know where they were. We don't know where they are." He adds: "I've got to be careful what I say here, to not get in trouble " I still have my security clearance." Other bodies have also been retrieved from subsequent incidents. He accuses major aerospace companies of trying to obtain crashed UAPs, to "reverse-engineer" the advanced machinery and replicate it. He warns that UAPs appear to be attracted to nuclear technology, sometimes interfering with weapons. He claims to have once even discussed setting a "trap" to catch a UAP by using US nuclear-powered aircraft carriers and submarines as bait. And he believes that UAPs have already cost lives. Ten people are said to have died in the "Colares incidents" after being harmed by lasers on a Brazilian island in the 1970s. Many of Elizondo's assertions rely on unnamed people, who he describes as "credible sources." But he also believes he's seen pieces of a UAP himself " and that he's even handled "alleged alien implants found in humans".
