102:45:17 Aldrin: 40 feet, down 2 1/2. Picking up some dust. [Armstrong, from the 1969 Technical Debrief - "I first noticed that we were, in fact, disturbing the DUST on the surface when we were something less than 100 feet; we were beginning to get a transparent sheet of moving DUST that obscured visibility a little bit. As we got lower, the visibility continued to decrease. I don't think that the (visual) altitude determination was severely hurt by this blowing DUST; but the thing that was confusing to me was that it was hard to pick out what your lateral and downrange velocities were, because you were seeing a lot of moving DUST that you had to look through to pick up the stationary rocks and base your translational velocity decisions on that. I found that to be quite difficult. I spent more time trying to arrest translational velocity than I thought would be necessary."]
