The parent is also incorrectly re-phrasing Murphy's Law -- "Anything that can go wrong, will go wrong."

Actual quote:

> “If there are two or more ways to do something, and one of those ways can result in a catastrophe, then someone will do it that way.”

Engineering controls basically mean making it impossible to do something in a way that results in catastrophe.

I'd be interested to hear why my restatement was incorrect. I'm confident that it's what Murphy meant, mostly because I've read his other laws and that's what I recall as the general through line. But that's was a long time ago and perhaps I'm misremembering or was misinterpreting at the time.
