The highly anticipated U.S. Pentagon report on UFOs released Friday reveals that all the bizarre sightings over the years fall into several categories, require more study, and remain largely unexplained and unidentified, reports CNET. “The limited amount of high-quality reporting on unidentified aerial phenomena hampers our ability to draw firm conclusions about the nature or intent of UAP,” reads the summary of a report posted online by the Office of the Director of National Intelligence. “… UAP clearly pose a safety of flight issue and may pose a challenge to U.S. national security.” According to the nine-page document, each report of UAP would “probably… fall into one of five potential explanatory categories: airborne clutter, natural atmospheric phenomena, USG or U.S. industry developmental programs, foreign adversary systems, and a catchall ‘other’ bin.”
