When we landed on the moon, we saw the ruins of a magnificent building.

I fell asleep on the plane, until during the middle of the night, we landed on the Azores Islands for refueling.

It was a really incredible thing that when we landed there, I was talking to various people, and they were saying to me, You've got to get everybody involved here.

And in those 50 years, not only did we literally, physically set foot on the moon, but we have dispatched robotic spacecraft to all the planets all eight of them and we have landed on asteroids, we have rendezvoused with comets, and, at this point in time, we have a spacecraft on its way to Pluto, the body formerly known as a planet.
