Patterned after the first volume published in 1964, is much anticipated by the research community. The book reports 30 years of UFO sightings since 1964 with related data and descriptive features organized by category. Among the topics discussed are the now strongly established patterns of UFO sightings, the growing evidence worldwide that UFOs represent someone's technology, the history of government sponsored UFO investigations, and political and human responses to UFO sightings. The master chronology is an incredibly complete listing, which also refers the reader to pertinent sections in the book for fuller descriptions.
