Former senior US national security chief Chris Mellon detailed incredible footage of a leaked US Navy video that shows a UFO. Mellon served for almost 20 years in the US federal government in various national security roles and has spent time at area 51. He held high-level clearance, was on a committee with oversight of all Department of Defense special access programs and spent a decade on the Senate Intelligence Committee.
Personnel aboard the USS Nimitz filmed the encounter that was said to have lasted for several hours. The UFO appears to out-maneuver several F-18 pilots and defy physics.
