Earlier this summer, the director of national intelligence and secretary of defense released a highly-anticipated, unclassified report about something the Pentagon calls unidentified aerial phenomenaor UAP"more commonly known as UFOs. The government's grudging acknowledgment of 144 mysterious sightings documented by our military comes after decades of public denial. Luis Elizondo spent 20 years running military intelligence operations worldwide. He hadn't given UFOs a second thought until 2008. That's when he was asked to join something at the Pentagon called the Advanced Aerospace Threat Identification Program, or "AATIP." Buried away in the Pentagon, AATIP was part of a $22 million program sponsored by then-Senate Majority Leader Harry Reid to investigate UFOs. When Elizondo took over in 2010 he focused on the national security implications of unidentified aerial phenomena documented by U.S. service members. "Imagine a technology that can do 6-to-700 g-forces, that can fly at 13,000 miles an hour, that can evade radar and that can fly through air and water and possibly space," [said Elizondo]. "And oh, by the way, has no obvious signs of propulsion, no wings, no control surfaces and yet still can defy the natural effects of Earth's gravity. That's precisely what we're seeing." AATIP's funding was eliminated in 2012, but ... last year, the Pentagon resurrected AATIP, it's now called the UAP task force; service members now are encouraged to report strange encounters.
