I think that's one thing people generally don't quite understand. I've seen so many people get angry with the airline employees at the terminal when the flight is delayed for some mechanical issue. It's just a bit baffling to me, do you really want to get on a plane that has an issue? It's not like you can just pull over into the median of the engine breaks down.

One time they had to change a tire and it took a well over an hour and some genius was losing his temper and shouting about how quickly he could change his car tire. Okay, yeah buddy lol.
