UFO intel report will not reach definitive conclusion, adding to mystery over sightings

U.S. officials investigating the UFO sightings by Navy pilots in recent years haven't reached a definitive explanation for the unidentified aerial phenomena, or UAPs.

American officials investigating the UFO sightings by Navy pilots in recent years have not reached a definitive explanation for the unidentified aerial phenomena, or UAPs, as they’ve come to be known, two U.S. officials confirmed to ABC News – adding a new layer of mystery to the interstellar drama ahead of an upcoming report on the matter. Investigators compiling a report to Congress due later this month are said to have found no evidence to suggest the UAPs are linked to alien spacecraft, nor are they in a position to explain what has been reported by U.S. military pilots in encounters over the years, the two officials said. A third official said that investigators have also ruled out the possibility that UAPs are related to any secret U.S. military technology, or so-called "black programs." Meanwhile, weapons experts are casting doubt on the possibility that the sightings are hypersonic technology belonging to America’s foreign adversaries.
