John Keel is one of the better writers in the UFO genre and quite imaginative. This book offers a "what if" scenario that has obviously not come to pass. If the beginning premise is that UFOs could be anything then this book almost has an air of plausibility. Almost. As is becoming apparent, UFOs from 1945 on appear to be man-made craft. The military and governments of all countries have responded in the same way: ridicule, denial, and more recently, the release of documents and records that show confusion and intense interest, at least in the early days, but, ultimately, no definitive action, aside from further denials and 'official' disinterest. Are UFOs a threat? Apparently not. Will UFOs go away? Apparently not.
