1950 era propaganda film by the U. S. Signal Corp of the then-new B-36 intercontinental nuclear bomber. Shown in movie theaters of the time, this film was not only to inform the U.S. public, but to let the Soviets know of the new technology that could rain nuclear destruction on the USSR. That propaganda blitz is described in detail in « Cold War Peacemaker – The Story of Cowtown and the Convair B-36 » which I co-authored with Dennis R. Jenkins. ISBN-10: 1580071279.
