Right, but none of the incidents on that list involved a nuclear missile silo. I read the author's sentence as "It would have been impossible (for Morris or other silo crew members) to start World War Three by accident."
Compounded with the thirty-four nuclear missile officers "texting answers to each other on a monthly proficiency exam" in 2014 [2] or the silo whose blast doors were left open while one crew member slept and the other awaited food deliver in 2013 [3], I'm don't see how that claim can continue being held.

That we are aware of. What's your acceptable threshold for accidentally vaporising a city?
These stories are usually ignorant of what the actual procedures were and how very far any launch scenario was. There would be secondary detection confirmation and everyone was well aware of what a false positive was.
No one was just launching on one set of data, if they did, we wouldn't be here to discuss it.
"Launch code for US nukes was 00000000 for 20 years"
Had it been in a James Bond movie, I'd have laughed "a good gag."
