However, in April 1961, Defense Secretary McNamara stopped the production go-ahead for the B-70 on grounds of rapid cost escalation and the USSR’s newfound ability of destroying aircraft at extremely high altitude by either missiles or the new Mig-25 fighter. Nevertheless, in 1963 plans for the production of three high-speed research aircraft were approved and construction proceeded. In September 1964 the first Valkyrie, now re-coded A/V-1 took to the air for the first time and in October went supersonic.
This book is the most detailed description of the design, engineering and research that went into this astounding aircraft. It is full of unpublished details, photographs and firsthand accounts from those closely associated with the project. Although never put into full production, this giant six engined aircraft became famous for its breakthrough technology, and the spectacular images captured on a fatal air-to-air photo shoot when an observing Starfighter collided with Valkyrie A/V-2 which crashed into the Mojave Desert.
The loss of the $750 million aircraft and two lives stopped future development, although there were several attempts to redesign it as an airliner to compete against the European Concorde.
"Graham Simons’ latest entry covers the exciting development and test history of this important aeronautical masterpiece in fine detail." ~Flight Line Book Review
