John Lear has access to the people who worked to reverse-engineer technology gained from civilizations originating on other worlds. Despite attempts to conceal these special projects, he reveals that a great deal of technology from other worlds has made it into the hands of powerful aerospace corporations that will do anything to keep their secrets. In this discussion with Emery Smith, he describes the technology used to fuel interstellar vehicles, what it is like to traverse vast distances across the cosmos, and why many of these extraterrestrial beings take an active interest in life on our planet.
