...or it might not. So we sit down and we think about it. Some
things, that being one of them, we'll want to take immediate action,
so we sit down and think about them before we go out and test. There
are probably few enough modes that need immediate action that we can
anticipate most of them.
For the modes where we don't need to take immediate action, let's not.
Rule #1 is, take your time and do it safely.
Of course, there will some modes where we guessed wrong. Fortunately
Dan overengineers his engines. I will never forget, "3, 2, 1, fire."
