This is the second part show no. 274 with Andrew Johnson discussing his new book on UFOs entitled "Acknowledged". In this episode we discuss the alien abduction phenomenon, and ask whether the military could be behind most alleged abduction cases. What about the ancient alien or ancient astronaut claims - Andrew brings to light what he believes is the best evidence for alien intervention in the distant past. We then look at some very intriguing photographs, video and physical evidence of alleged extra terrestrials on Earth. Could any of this evidence really mean that we have been visited by intelligent races from elsewhere in our galaxy?
