Pentagon task force's UFO report released - many cases remain unexplained

After decades of dismissing U.F.O. sightings popularized in American culture, a U.S. government task force assigned to investigate what it calls "unidentified aerial phenomena," or UAPs, has found no evidence that objects came from outer space or a foreign adversary.  Airborne clutter, like birds, balloons and plastic bags Natural atmospheric phenomena, like ice crystal formations or thermal fluctuations Industry developmental programs Foreign adversary systems, including possible technologies deployed by Russia or China  "Other," which, the officials said, was a "catch-all" section where a lack of data or scientific knowledge meant the incident was uncategorizable.

However, while there's no evidence the objects are extraterrestrial, senior government officials said Friday that nearly all of the incidents investigated remain unexplained. "Of the 144 reports that we are dealing with here, we have no clear indications that there's any non-terrestrial explanation for them," a senior government official said, nixing the possibility of exotic sightings. "But again, we will go wherever the data takes us on this."
