In this UFO book, the authors comment on a series of incidents which turned out to be something very different than first imagined. Like true-life crime cases, they report the facts of each case, probe all aspects of it, interview witnesses, examine all possible explanations and come to a conclusion. The cases include the UFO which reportedly crashed into a reservoir whilst pursued by jet fighters, the alien photographed by police after a high-speed chase, the recent wave of UFO activity in Florida abd the infamous Roswell crash and autopsy.
