Over the weekend, the USA's Office of the Director of National Intelligence released a document entitled, 'Preliminary Assessment: Unidentified Aerial Phenomena'. The report stated that 'the limited amount of high-quality reporting on unidentified aerial phenomena hampers [their] ability to draw firm conclusions about the nature or intent of UAP' but 'UAP clearly pose a safety of flight issue and may pose a challenge to U.S. national security.' 'Safety concerns primarily center on aviators contending with an increasingly cluttered air domain. UAP would also represent a national security challenge if they are foreign adversary collection platforms or provide evidence a potential adversary has developed either a breakthrough or disruptive technology.' However, the report concedes that the unusual flight patterns often associated with UAP or UFOs could be down to 'sensor errors, spoofing, or observer misperception and require additional rigorous analysis. ' Leslie Kean, Journalist and New York Times bestselling author of UFOs: Generals, Pilots, and Government Officials Go on the Record, joined Stefanie Preissner on the show to discuss what this report could mean for mankind.
