Does this actually include a flight? It'd be a waste of money otherwise, as nothing other than doing it can prepare you for things like the jets thrusting you along the runway, the steep climb and banking, or the way the plane just seems to drop in the sky when it is circling to land.
Just read that back and I've probably scared the "C" out of you more, but really, unless you experience it, nothing can describe it, and more to the point, there really is no need - especially now with all the electronic safeguards - to worry about anything. Aside from the cabin crew selling stuff, waiting for the toilet, and noisy passengers sometimes, flying is great.
