The existence of UFOs had been proved beyond reasonable doubt, according the head of the secret Pentagon program that analyzed the mysterious aircrafts. Luis Elizondo [said] of the sightings, In my opinion, if this was a court of law, we have reached the point of beyond reasonable doubt. I think its pretty clear this is not us, and its not anyone else, so no one has to ask questions where theyre from. Elizondo led the U.S. Defense Departments Advanced Aerospace Threat Identification Program, investigating evidence of UFOs and alien life, from 2007 to 2012, when it was shuttered. Its existence was first reported by The New York Times last week. Elizondo [said] that there had been lots of UFO sightings and witnesses interviewed during the programs five years. Investigators pinpointed geographical hot spots that were sometimes near nuclear facilities and power plants. They also observed trends among the aircrafts, including lack of flight surfaces on the objects and extreme maneuverability. There was never any display of hostility, but ... they maneuvered in ways no one else in the world had, he said. Despite Pentagon funding running out in 2012, Elizondo oversaw UFO work for another five years before resigning in October 2017 out of frustration with the secrecy of the investigations. He had pushed for videos of the possible alien sightings to be made public so people could see the footage. In his resignation letter to Defense Secretary Jim Mattis, Elizondo asked, Why arent we spending more time and effort on this issue?
