The second book of its kind, the UFO Sightings Desk Reference: United States of America 2001 – 2020 presents data and analysis for 167,632 sighting reports of unidentified flying objects reported by individuals during the first 20 years of the 21st century. Since 1969, the government has claimed no interest in the subject and the press and media either ignore or ridicule mention of UFOs. Yet citizen scientists and nongovernmental organizations have continued to this day the research into this important subject: this book seeks to make the hardest data accessible to the general public, as well as other UFO researchers.The book is organized into beginning narrative sections including analysis of UFO sighting reports, followed by the data. There are no case studies or stories. Charts, tables, and maps are presented of summary data for the entire United States. An individual chapter for each of the 50 states plus the District of Columbia. Aimed at the serious UFO researcher, this comprehensive volume is also of value to academic and public libraries, news organizations, and anyone who is interested in what is flying in the skies over the heads where they live.
