"The book reports on thirty years of UFO sightings since publication of the first volume, with related data and descriptive features organized by category. In this report, sightings are arranged by witness categories. Among the topics discussed are the now strongly established patterns of UFO sightings, the growing evidence worldwide of UFO technology, the history of government-sponsored UFO investigations, and political and human responses to UFO sightings. The master chronology refers readers to pertinent sections in the book for fuller descriptions."--BOOK JACKET.
