But the underdog Soviets scored a series of victories—starting with the 1957 launch of Sputnik and continuing in the years following--that seemed to achieve the impossible. It was proof, it seemed, that the USSR had manpower and collective will that went beyond America's material advantages. They had asserted themselves as a world power. But in The Wrong Stuff, John Strausbaugh tells a different story.
