There was an interview with Petrov (in the 90s or 00s) when he spoke about this point, and the interviewer said that in 1983, the US plans for a preemptive strike started with a "beheading strike", in which a few missiles would be sent to hit the Kremlin and a handful strategic military bases. Then the US would wait if the Soviets were still twitching, in which case the second, more massive round would've been fired. Petrov admitted that, if he had known that, he would've decided differently on that fateful day.
(Don't have a direct source link to back this up, sorry. My source is one of the earlier episodes of https://alternativlos.org where they talked about the Cold War.)
Then again, it's not a proper Cold War strategic game theory play unless you're banking on your enemy to hesitate due to the unusual nature of the attack. SLBMs scream first strike, while a few birds out of many launching from farm country in the central United States in sequential fashion, not so much.
That said, I'm not sure what would have consituted "twitching" after Soviet C&C is wiped out, and if I was a planner at the time I don't think I'd want to find out. It would likely have been prudent to immediately follow up the decapitation strike with complete annihilation of Soviet nuclear retaliatory capability. Every deployed Soviet boomer accounted for and shadowded, with firing solutions computed. Every missile silo targeted. Presumably strategic air bases would be targeted in the first volley, though there would remain the possibility of strategic bomber patrols already airborne.
First strikes are really messy and entail a ridiculous amount of risk. Considering the stakes, it's no wonder neither side ever tried.
The original mistake was just an autocorrect error. Some day I'll learn not to write posts from mobile devices.
Also, I noticed you created an account just for this. Assuming it isn't a throwaway, welcome to HN. That's a cool username.

"The factory was to be a vast installation, comprising fifty buildings" is the same kind of use.
Nowadays there’s an automated system in place that ensures a response even if the entire high command is taken out: https://en.m.wikipedia.org/wiki/Dead_Hand_(nuclear_war)
Wow, so given Petrov's response, this plan might have actually worked. Those clever generals. (Insert emoticon of me being horrified right now..)
There isn't really a workable first strike plan, and that's probably a good thing.
So why you're spreading FUD, if you have nothing to prove your point?
The reason Petrov is to be considered a hero of old times is not just because he was able to spot a mistake, but to report something different from what he saw. He took the liberty to decide for an entire nation, and as he also admitted, the 12-13 minutes during which these potential nukes were supposed to reach their final destination were "really long". If he had been so certain, he'd have had no issues - he based his decision on his instinct.
If he had simply followed the rules (pretty common in a military hierarchy), we'd probably not be here today. This is what makes this man exceptional - the fact that in the end he even got scolded for not obeying the rules, and that he died "almost" in misery.
Anyway, it uses that incident to go back in history and explain the development of nuclear weapons and how the command and control systems we have today came about. A lot of it was driven to prevent all sorts of near-miss accidents that have happened in the past. We've been really, really lucky.
Highly recommend the book, especially for the HN crowd. It's good prose, but gets deep enough into the tech and system details that you come away with a solid understanding of how it all works.
Due to his knowledge of the early warning system he was more likely to cast doubt than a regular officer on duty. Several factors looked suspicious: 1) The reported starts (5 in total) happened from a single base in the US which didn't make sense from the military point of view: the US would have put themselves at a grave disadvantage by sending just a few missiles; 2) They had visible light and infra-red visuals on the US territory and none of them checked out and 3) It would have been highly unlikely for the war to start suddenly, without any prior escalation.
Like other officers on duty, he had college education as an electronics engineer and additional 2 years of special training. All this probably helped him make the right decision.
This is not to take away from the importance of Mr.Petrov's heroic personal contribution: he definitely deserves recognition (which he didn't get from the Soviet Army and his own country BTW). Still I would also like to hope that we are all collectively not as stupid as to go caboom just because of the single fluke in the satellite system.
