but will be going on one in a couple of weeks, and really don't like the thought of being in a bus in the sky, or turbulence, or seeing the ground drop away (i get really freaked out by the heights on rollercoasters and those spinning umbrella things at funfairs) or seeing the ground racing towards you, or generally being in the air, and what if it crashes and what if something goes wrong and what if i freak out in the middle of the plane and go all Peter Buck on the person sitting next to me andwhatifitsthelastjourneyievermakeandifalloutofthesky???
