Wow - had no idea each pre-flight check includes an alternate airport for landing - thought all of that was figured out on the fly.

I do have a quick question for you - you mentioned maintenance variances - how often do you fly with something wrong with the airplane (obviously, non life-threatening)? Do you ever fly with a lack of redundancy? Are you allowed to? I would assume there's something wrong with the plane the majority of the time (even if it's something that has nothing to do with its ability to fly), but I've often wondered to what degree are things broken on a plane and yet still pass "ok to fly".
