Today is September 26th, Petrov Day, celebrated to honor the deed of Stanislav Yevgrafovich Petrov on September 26th, 1983.  Wherever you are, whatever you're doing, take a minute to not destroy the world.

The story begins on September 1st, 1983, when Soviet jet interceptors shot down a Korean Air Lines civilian airliner after the aircraft crossed into Soviet airspace and then, for reasons still unknown, failed to respond to radio hails.  269 passengers and crew died, including US Congressman Lawrence McDonald.  Ronald Reagan called it "barbarism", "inhuman brutality", "a crime against humanity that must never be forgotten".  Note that this was already a very, very poor time for US/USSR relations.  Andropov, the ailing Soviet leader, was half-convinced the US was planning a first strike.  The KGB sent a flash message to its operatives warning them to prepare for possible nuclear war.

On September 26th, 1983, Lieutenant Colonel Stanislav Yevgrafovich Petrov was the officer on duty when the warning system reported a US missile launch.  Petrov kept calm, suspecting a computer error.

Then the system reported another US missile launch.

And another, and another, and another.
