Fly in a Concorde

This one sucks, because the Concorde is out of commission. But my point is not so much flying in that plane, or even flying at supersonic speeds. The Concorde, as impractical as it was, was the most practical way to get as close to space as an average guy like me is going to get. Can you imagine being at an altitude so high you can clearly see the curvature of the Earth? It's gotta be unreal. I'm certain I'd spend my whole flight just glued to the window. In fact, I'd better get a window seat!
