re: Clarification:
"Rutan is competing for the suborbital X-Prize, and is a top contender. However, his design is not easily upgradable to something that can go into orbit. He will have to develop something new if he goes after that market. "
Oh. Ok.
Is vehicle upgradable for sub-orbital travel?
I think sub-orbital travel could better market than orbital, at least in the near term.
