Shuttle capability

I think that was a mistake. Space Shuttle was and remains the most capable flying machine ever conceived, built and operated. We learned much from the thirty years of Shuttle flights, and in my opinion, we should still be flying them. Shuttle carried a crew of seven, plus nearly sixty thousand pounds of payload to low earth orbit. After transforming from a rocket into an orbital research or construction platform, it entered the atmosphere and landed on a conventional runway at the end of its mission. After around one hundred days of processing, it was ready to fly again.
