Jesus can you relax? Sometimes statements aren't meant to be taken exactly literally. I don't mean to be hateful but what do you get out of being needlessly pedantic? Obviously there's more time actually spent on modern airliners. OP is using it as an analogy to show that it's a complicated process, and isn't saying that it's scientifically 1 to 1 exact.

It's this type of comment that makes people be needlessly careful on this site more than any other. When you know there is someone just waiting to correct you when you use a simple turn of phrase.
