Further anxiety could well result from concern about the pilots state of mind and hence ability to fly an airplane.

I fly an awful lot these days. If a pilot pulled a stunt like that while the door was still open, I'd get up and leave for precisely this reason. If he pulled that stunt after the plane was in the air, I'd most likely sit there in stunned silence. If I got my composure back before the pilot finished, I'd whip out my camera and record his behavior to ensure he gets his due.
