Stanislav Petrov

person · earth

Lieutenant colonel of the Soviet Air Defence Forces who was the duty officer at the Oko early-warning command centre south of Moscow on the night of 26 September 1983 when the system reported the launch of an American intercontinental missile, and then of several more. His duty was to pass the report up the chain; he judged it a malfunction and reported it as such, on reasoning he gave afterwards: a genuine American first strike would not consist of a handful of missiles, and the ground-based radars that should have confirmed the tracks had seen nothing. He was right, and the cause was later attributed to an unanticipated sunlight reflection. Two cautions belong in the record. Petrov himself consistently played down the idea that he had personally prevented a nuclear war, pointing out that his report was one input among several and that confirmation from other systems would have been required. And the episode only became publicly known in the late 1990s, through the published recollections of a senior officer, so it is documented largely through testimony. He died in 2017.

A person is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
