If I was on a plane and it was going down, instead of panicking I hope that I would do this:

I hope that I would grab the nearest lonely person and hug them and kiss them. Not romantically, just lovingly. After I did this I would then tell them that someone in the world wanted to do that to them at that exact moment in time, and that they are loved very much. I don't care who it would be, old young, man or woman. Because someone who is about to die needs to either be doing something that makes the moment worth living, or be reminded why they ever lived in the first place.
