The Sir Jack Files, special edition: Twenty-Three Minutes

Near Moscow. September twenty-sixth, nineteen eighty-three. Just past midnight. In a secret bunker, a forty-four-year-old lieutenant colonel takes the commander's chair.

His job: to watch the satellites that watch America's missile fields. Then, the alarm. Petrov: “The siren howled, but I just sat there for a few seconds, staring at the big, back-lit, red screen with the word 'launch' on it.” His name is Stanislav Petrov.

And the machine is telling him the world is about to end. The system is called Oko. Russian for eye. Satellites, high above, watching for the heat of a rocket engine.

One missile. And the computer rates its own confidence: highest. And again. Petrov: “A minute later the siren went off again.

The second missile was launched. Then the third, and the fourth, and the fifth.” The alert changes. From launch, to missile strike.

The rules are clear. He reports up the chain of command. And in nineteen eighty-three, the protocol for an attack is an attack in return. He freezes.

Petrov: “All I had to do was to reach for the phone; to raise the direct line to our top commanders, but I couldn't move.” The room is roaring. Maps flashing. A phone in one hand, an intercom in the other.

Another officer on the line, shouting at him to stay calm and do his job. But something doesn't add up. One. He'd been told many times: a real attack would be massive.

Petrov: “When people start a war, they don't start it with only five missiles.” Two. The system is new. He has worked on it since the start, and he knows it was rushed into service.

In his word: raw. Three. The ground radars show nothing. They can't see past the horizon yet, so they prove nothing.

But they show nothing. Four. Every alert had to pass twenty-eight or twenty-nine checks. This one passed them all.

Too clean. Everything on the screen says yes. Everything in him says no. Petrov: “I had a funny feeling in my gut.

I didn't want to make a mistake. I made a decision, and that was it.” He picks up the phone. Not to report an attack.

To report a malfunction. If he's wrong, the first warheads land within minutes. Nothing comes. Petrov: “Twenty-three minutes later I realised that nothing had happened.”

The cause was sunlight. The sun lit the tops of high clouds, and the satellite read the glint as a rocket's flame. The software meant to filter that out was rewritten. There was no medal.

Investigators asked why he hadn't written everything down that night. Petrov: “Because I had a phone in one hand and the intercom in the other, and I don't have a third hand.” He got an official reprimand, over mistakes in the logbook. For years, he kept the story to himself.

He was the only officer on his team with a civilian education. The others were career soldiers, trained to give and obey orders. He believed any of them would have raised the alarm. Petrov: “That was my job.

But they were lucky it was me on shift that night.” Machines are faster than we are. They count better, watch longer, and never sleep. That night, the machine was certain.

And it was wrong. In Detroit, in twenty twenty, people believed a computer that said Robert Williams was a thief. He spent thirty hours in a cell for it. Today, people talk about an AI-centred world.

We don't want one. We want a human-centred world, where every machine that matters has a person who checks it, and who can say no. Europe's AI law now says high-risk AI must be built so that people can oversee it. Stanislav Petrov died in twenty seventeen, at seventy-seven.

In every machine we build, there should be a chair like his. And someone in it. The Sir Jack Files. Case closed.
