I tend to run through scenarios in my mind (benefit[?] of being in a plane crash already) but you left off the important part, Harry — not what to do when you can't do anything, but what to do when you CAN do something, post-landing. (Or post-crashing, but if you can walk away from it that makes it a "landing" not a "crash," right? I defer to you, the trained pilot; as an ex-submariner I'm better versed on the difference between "leaking" and "flooding." 😁)
Good news[?] is that I only fly now when I'm with Deb. We tend to work well together.
I like Whye Waite's approach!
