This is NASA we're talking about here. Their goals have never been to open up space for the average person. Even if they have this new whiz-bang SSTO toy they can be expected to:
1. Make it more inefficient and expensive than anyone could imagine. (They were predicting $100/lb. to LEO for the shuttle in the 70's.)
2. Only allow super-elites to ride their toy. No civilians except politically correct feel-good choices from NASA for a PR stunt. (McCauliffe,Glenn redux)
This just isn't a game that NASA wants to play. It's up to private non-government orginizations to get us to the point of Arthur C. Clarke's vision in 2001 A Space Odyssey.
As for NASA, as soon as that space plane is a reality, I'd close it down. I'd then wait three years. At the end of three years I'd develop some form of national service like the Navy to oversee it.
Why do I suggest that? All we need is for some NGO like the Sierra Club or Greenpeace to get their meat-hooks into it. I'm open to any suggestions, but I'll be damned if I'll agree to another NGO taking over. I may dislike government, but at least they answer to someone. Those NGOs don't answer to anyone including God.
