Taking us through a logical progression of factual, first-hand experiences, Keller will present the case that this fleet of spacecraft carriers is now in operation. Presenting a history of reports of very large, cigar-shaped spacecraft that have been seen in the skies and in orbit around Earth. Are these craft of extraterrestrial origin or are they man-made? Keller will discuss the reasons why he believes this is a real phenomenon, and why he believes in the existence of a secret international, human-constructed space fleet. This talk will also include discussion of a proposed construction methodology for these spacecraft, as described by Gary McKinnon. He will identify the industries capable of such a manufacturing process and explain them in some detail. Keller will then share a hypothesis that he has developed as a result of his research into these areas.
