内容简介：
This book was inspired by, and is loosely based on, "The UFO Experience: A Scientific Inquiry" (1972) by the late Dr. J Allen Hynek. Dr. Hynek's book is generally considered to be the most influential book ever written about UFOs, but much has happened since 1972. This new book not only brings us up-to-date, but extrapolates on current science whenever possible. Perspectives are offered in three basic categories: natural causes, domestic technology, and alien technology. But perhaps more importantly a new way of looking at the phenomena is proposed that has been largely overlooked by other authors, and which finds itself at home in any of these three possibilities. The reader will not find discussion of conspiracy theories, accounts of abductions, or metaphysical and supernatural hypotheses. However, one will find speculations about possible alien visitations, what alien technology might be capable of, or what the distant future might hold.
