Why It Matters
During the Cold War, the United States and the Soviet Union were engaged in a nuclear arms race. Early warning systems were supposed to report missile attacks, but were prone to false alarms.
Sometimes it's the things that don't happen that decide the course of world history. That's how it was on September 26, 1983. If Lieutenant Colonel Stanislav Yevgrafovich Petrov had believed his computer that day, world history might have ended. Everyone alive today can be grateful to Petrov for trusting his intuition more than the machine.
Petrov would actually have been off duty that day. But he stepped in for a sick colleague and reported to the Soviet missile early warning command post at 11 p.m. on September 25th, in an underground bunker 100 kilometers south of Moscow.
