I ALWAYS follow the same procedure when on the ground. I note the exits, look behind as well, and plan my escape. 'jump over those poeple in front, 'cos they are not listening, and won't know what to do, kick that big guy in the teeth because he won't know either. Etc. On the ground, I can do something to save myself. In the air, I can do nothing, so don't worry at all. I ALWAYS read the card, mainly because it encourages the guy next to meto do the same, otherwise they probably wouldn't bother.
