The shuttle has been cancelled, Atlantis is flying her last mission, so NASA disagrees with you that the shuttle is a viable concept, if it were viable, they would be building new shuttles.

My idea has not been tried, so it is possible that it could work, the number of *experts* who got it wrong like the guy who said the planet would only need about 5 computer.

Or Bill Gates who said "640K of memory should be enough for anybody."
