The first public congressional hearing into UFO sightings in the US in over 50 years ended with few answers. Two top military officials tasked with probing the sightings said that most can ultimately be identified. But they said a number of events have defied all attempts at explanation. The sightings recorded by the military include 11 near-misses" with US aircraft. Some Unexplained Aerial Phenomena (UAPs) - as the military terms UFOs - seem to have been moving without any discernible means of propulsion. During the hearing at the House Intelligence Counterterrorism, Counterintelligence, and Counterproliferation Subcommittee, top Pentagon intelligence official Ronald Moultrie said that through "rigorous" analysis, most - but not all - UAPs can be identified. In 2004, fighter pilots operating from an aircraft carrier in the Pacific encountered an object that seemed to have descended tens of thousands of feet before stopping and hovering. In another incident ... an object can be seen on camera flying past a US Navy fighter jet. The object remains unexplained. "There are a small handful [of events] in which there are flight characteristics or signature management that we can't explain," said Scott Bray, the deputy director of naval intelligence. "Those are obviously the ones that are of most interest to us." [In 2017], pilots described seeing them on an almost "daily basis" outside military bases, and one whistleblower described how UAPs had interfered with US nuclear weapons facilities, even forcing some offline.
