For many decades there have been detailed reports of sightings of unfamiliar crafts in the sky and sometimes resting on the ground. The reports come from airline and military pilots, astronauts, law enforcement officers and other respected persons of all walks of life, from about 60 nations. These objects have often been tracked on radar, and frequently photographed. The speed, maneuverability and other performance attributes of these craft has far exceeded anything within the capability of any entity on Earth. There have indeed been many mistakes and a few hoaxes, which does not affect the efficacy of the others. Though our government has denied their existence, they have confiscated every scrap of physical evidence, and conducted extensive research in an attempt to duplicate the crafts' performance. We all hope they succeed. But, this book argues, there is no need to deny to the civilian population the other benefits to be gained, that are of no interest to the military.
