This book is the serious work of a professional aerospace engineer. It shares profound discoveries made during 40+ years of objective research, about the nature of UFOs, especially those with craft-like characteristics. It covers virtually all aspects of the phenomenon, including those stories of close encounters with alien creatures and of time-loss and claimed abductions by the witnesses. Within these pages you will discover that genuine sightings and encounters are shown to have been in accordance with (now identified) ages-old programmes, referencing the sun and selected stars. This predictable system seems to have been set up, aeons ago, to facilitate long-term monitoring of our species by fully automated craft, some of which could be operating routinely, without occupants, from the outer fringes of our solar system. The technology being used is currently beyond us – but why should we expect it to be otherwise? It is revealed that several alien species seem to be co-operating and generally following the same rules of engagement with this planet.
