That's the Petrov story, which has legs, but doesn't seem very important to me. Essentially, he was using some new equipment and saw 5 incoming missiles. He decided against acting upon that information as he saw it, rightfully, as a bug. He may have gotten into some trouble with his superiors, but I imagine that has a lot more to do with the face-saving bureaucracy of the USSR than a readiness to launch with such limited information.
There must be a mountain of research into false positives of launches and more false positives than we know. After the fall of the USSR we found that that this happened practically regularly. I believe the Soviets saw the Able Archer exercises in 1983 as a potential attack and even detected missile launches. We also found out that Castro was ready to start nuclear war until his Soviet masters explained to him what that really means.
This is also why nuclear launch approval tends to be from the head of state only, instead of an automated process or via lower level delegates.
