David Myhra, PhD, has written more books and Ebooks (50+) on World War Two German flying machines and their designers than anyone living or dead. He has interviewed dozens of former German aviation designers and gas turbine and rocket scientists throughout the 1980's in places such as West Germany, East Germany, France, USA, South America and other countries. He was also involved in the production of numerous TV documentaries such as the History Channel’s 2005 “Nazi Plan to Bomb New York” and the National Geographic TV Channel’s 2009 documentary “Hitler’s Stealth Fighter.” (This featured the building of a full-scale replica of the Horten Ho 229 V3 by the Northrop Corporation and its radar cross section (RCS) testing at their classified radar test range in the California Mojave Desert.)
