I guess it wasn't the author's fault, but that's the one of the most ridiculous things I've ever seen. Until about 1990, anti-aircraft missiles were horribly inaccurate. I read somewhere that the chance of scoring a hit with a korean-war era air-to-air missile was about 5%. Why would anyone want to launch a nuclear missile that's pretty much guaranteed to not his its target?
