I designed the Avionics for the XB-70 Valkyrie Stealth Bomber when I worked for the Autonetics Division of North American Aviation, which later became Rockwell International, which later became Boeing as indicated on my Retirement check which I receive monthly. I spent thirty years before I retired from Autonetics devising ways to eliminate the Soviet Union which collapsed of its own accord in 1995 while I lived in Spain. Many Russians from the USSR moved to Malaga, Spain, where I lived for almost 20 years. The Russians seated 30% of the Symphony Orchestra including the Concert Mistress (1st Chair Violin). When I met any Russians in Malaga, they appeared such nice people it made me wonder why we wanted to eliminate them during the Cold War. This book describes in detail the SR-72 Blackbird as the stealth Surveillance Aircraft which cruised at near orbital altitudes. Other versions were fighter aircraft or large bombers. Your author participated in the design of the first version of stealth aircraft when they were so classified they could not be discussed in News Media.
