1983Stanislav Petrov Averts Nuclear False AlarmSoviet officer declines to report missile warningSoviet Air Defence officer Stanislav Petrov judged a satellite warning of incoming US missiles to be a false alarm and did not relay it up the chain of command, likely preventing a retaliatory nuclear strike.
