설명
Dave Warner is an aerospace engineer located in Houston. After reading several studies on the ancient megalithic structures and the monolithic stones used to build them, some weighing several hundred tons, Dave had to know how they did that with only manpower and ropes. When the answers land in his lap, Dave is stunned by the rest of the story.
