What if there really are aliens and they do attack? Read what two scientists reveal in this “how-to” survival manual for the space age. Alien invasion. Unlikely? As unlikely as Pearl Harbor? The extinction of the dinosaurs? A meteor strike that levels whole forests in Siberia? You get the drift. Some events produce such a massive setback to life, the Earth and to humanity that we must understand and prepare for them, even if the chances are low that they’ll come about. In fact, it will be criminal and abrogation of our duty to future generations if we do not get ready! But where to begin? Drs. Travis S. Taylor and Bob Boan have the answers. Both are experienced scientists, physicists with expertise in both defense and military signal intelligence and experience working with both the Department of Defense and NASA. These are intellectual heavyweights who have a clear idea of the possibilities of alien contact, the calculations of whether or not that contact will be friendly...and what to do if it’s not.
