* Sample: "Imagine that you are the commander of a B-52 jet bomber of the United States Strategic Air Command. You are in flight toward an enemy target. You are carrying thermonuclear bombs ... Do you proceed to your target, does your bombardier press the button and does the first nuclear bomb 'go down the chimney' to start World War III? All this because one of the Strategic Air Command's vast fleet failed to receive a turn-back order? Not so. You are saved, you and many others, by a powerfully simple plan called Fail Safe. It is proof against error, human or mechanical."
