If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

We should remember that science exists only because there are people, and its concepts exist only in the minds of men. Behind these concepts lies the reality which is being revealed to us, but only by the grace of God.

The rocket worked perfectly, except for landing on the wrong planet.
