I live near a tiny airport where someone apparently gives flying lessons.  While I'm working outdoors, I will hear the engine of the silver single-engine plane above me suddenly quit.  I can almost hear him telling his student:  "Okay, NOW what are you going to do?"
For many years, it has been a "hobby" of mine to figure out what would be the best thing to do before it happens:  If I do something dumb like stop on the railroad tracks & the barrier comes down, would it be better to back up or go forward?  If some maniac with a knife tried to get into my car at a red light... If I walked into the local mini-mart with my head down, right into an armed robbery.  Etc.
When I first noticed that I was doing this, I asked my sister if she every did that.  She just looked at me like I had grown ears on the top of my head, and said, "NO!  Why would I want to do that?"
So far, I've never run screaming from the scene.  I usually do what needs to be done, then fall apart afterward, which still seems kind of whimpy...
On TV, I saw a woman who had stopped her car at the RR crossing, & then was rear-ended and knocked into and grabbed by the passing freight train.  What on earth SHOULD you do in a case like that, anyway???
