What is your opinion on the new shuttle-like spacecraft that was unveiled just the other day? (Referring to the X-33)

The X-33 is a very demanding idea. The concept is that it will be totally reusable. The requirement is to go into orbit on only one stage, in other words, that it is totally reusable and propelled by only one stage which is a very demanding requirement. It is a high-technology, state of the art, flying machine.

My own approach might be a little different. Since the early 70s, I have always been interested in using a reusable capsule. I would like to see, as well as the high-tech machines, a low-tech approach to getting in and out of space, such as a reusable capsule.
