It takes over 30 times as much energy to enter orbit (Shuttle ISS) as it does to go straight up and fall straight down (Space Ship One). And you have to get rid of all that energy coming down which is why the Shuttle needs TPS tiles and Space Ship One doesn't. This comparison doesn't even include the difference in altitude (200 Mi Shuttle ISS) vs 60 Mi (Space Ship One). Hence the $200k vs $20M price. http://en.wikipedia.org/wiki/Specific_orbital_energy#Earth_orbits You guys are completely missing a very important point.

At the moment it would just be a way to get passengers, fuel and cargo into orbit. I have already covered the commercial spaceflight opportunities and they don’t quite reach into space station orbit but the way things are progressing in that area it won’t be long. It would be quite a big step down for NASA, even if they said they were temporarily relying on commercial rockets. With the cost savings and convenience it may never be possible to go back to their own rockets.
