On 26 September 1983, the computers in the Serpukhov-15 bunker outside Moscow, which housed the command center of the Soviet early warning satellite system, twice reported that U.S. intercontinental ballistic missiles were heading toward the Soviet Union. Stanislav Petrov, who was duty officer that night, suspected that the system was malfunctioning and managed to convince his superiors of the same thing. He argued that if the U.S. was going to attack pre-emptively it would do so with more than just five missiles and that it was best to wait for ground radar confirmation before launching a counter-attack."
