I thought, well. when I step off it's just going to be a little step — a step from there down to there — but then I thought about all those 400,000 people who had given me the opportunity to make that step and thought it's going to be a big something for all those folks and, indeed for a lot of others that weren't even involved in the project, so it was kind of a simple correlation.

Our autopilot was taking us into a very large crater, about the size of a big football stadium with steep slopes on the crater covered with very large rocks about the size of automobiles that was not the kind of place that I wanted to try to make the first landing.

Thank you, Mr. Chairman. I am in the position of a pilot without his checklist, so I'll have to wing it a bit. ... [Prior to the Apollo missions,] no one knew what kind of person could be persuaded to take the trip. Prisoners were suggested. Soldiers could be ordered. Photographers could take pictures — and they're expendable. Doctors understood the limits of human physiology. Finally, both sides picked pilots.

A century hence, 2000 may be viewed as quite a primitive period in human history. It's something to hope for. ... I am, and ever will be, a white-socks, pocket-protector, nerdy engineer — born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow. As an engineer, I take a substantial amount of pride in the accomplishments of my profession.

Space has not changed but technology has, in many cases, improved dramatically. A good example is digital technology where today's cell phones are far more powerful than the computers on the Apollo Command Module and Lunar Module that we used to navigate to the moon and operate all the spacecraft control systems.

The exciting part for me, as a pilot, was the landing on the moon. That was the time that we had achieved the national goal of putting Americans on the moon. The landing approach was, by far, the most difficult and challenging part of the flight. Walking on the lunar surface was very interesting, but it was something we looked on as reasonably safe and predictable. So the feeling of elation accompanied the landing rather than the walking.

I remember on the trip home on Apollo 11 it suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.
