Anti-Gravity Propulsion Dynamics

This text introduces a brand new field of scientific research based upon analysis of artefacts retrieved from crashed and damaged UFOs that have come down in Russia and America. For the first time, it reveals the scientific principles behind UFO propulsion dynamics and shows that these principles are known and recognised by today's physicists. Potter's analyses of these UFO mechanisms are substantiated with references to a broad array of over 300 research papers published in scientific journals!
