- Aldrin: We're about a minute, maybe 2 minutes, into powered descent, facedown, and Neil says to me, and the Earth, "I think we're gonna be a little long." I said to myself, how in the world can he really, at this point, tell that we're gonna be a little long? But sure enough, we were.
- Neil Armstrong, commander, Apollo 11: Prior to igniting the lunar module's descent engine to initiate the trajectory toward the lunar surface, I had been timing our angular rate over the craters on the surface below to calculate our altitude. I noted that, at ignition, we were somewhat west of our intended starting location. I inferred that our entire trajectory and landing point would be somewhat west of our planned landing spot.
- Aldrin: I've learned that whenever Neil says anything, you'd better pay attention because there's good meaning to it.
