I fly the Dash and while we single engine taxi (me sitting in the back in uniform), ppl usually will ask if we know that number 1 isn't turning and if we will start it before we depart. It's funny to see them sweating bullets while I'm just reading or trying to sleep. I tell them we do it to save fuel and that the jets do it too, you just don't see the blades turning. Some of them totally think I'm still "BS" ing them.
