One of the most interesting books I have read to date. Mr. Stevens makes the argument that the UFO investigators of today have made the leap to believing everything strange we see in the sky is from outer space, before ruling out all possibilities from earth. It is a fact that Nazi Germany was advanced in many areas, and they were the source of much of the technology we take for granted today. However, were they further along than we may ever know? Did they create and perfect disc shaped planes or alternate propulsion systems? This book explores this possibility. The airframe and propulsion designs are covered in great detail. He also goes into great detail discussing post-war research by other governments. 268 pages pb
