This list constitutes a very limited scope of the entire mountain of available data (thousands of pages that span over 7 decades) on this subject, but do make up some of the best mass sightings of UAP's (Unidentified Ariel Phenomena) and 5 of the highest level, credentialed, military/FAA (Federal Aviation Administration) personnel to date, and their testimony alone is enough to warrant taking the subject of exopolitics seriously. The five mass UAP sightings span over 60 years, from WWII to 2011, at minimum hundreds of thousands (probably millions) of eyewitnesses who saw them. All of them were reported by the media at the time.
