"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."

“I guess we all like to be recognized not for one piece of fireworks but for the ledger of our daily work.”

“I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul ... we're required to do these things just as salmon swim upstream.”

“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.”

“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.”

“That's one small step for man, one giant leap for mankind.”
