In my Engineering class we watched a video of one of the best rockets. It basically looks like 2 airplanes fused together by wings, and has a long pod attached to the bottom. The plane flies it up as far as an SR 71 and lets go of the pod, then the pod rockets out of the earths atmosphere, and brings you into space.
The cool thing is, nothing is wasted. With normal rockets, the rockets on the side and front of the shuttle are dropped down to earth. But on this rocket, the plane part that carries it up is piloted by 2 pilots, and when they deploy the pod, they fly back.
Heres a picture of the rocket, ignore the pod thing on the left.

Heres a model built by a different company, its basically the same thing.

If you had the chance, would you do it? I would definatley do it, I'd give everything I own just to go into space.
