But that seemed like a logical suggestion. Both vertical? Reyes was Chief of the Pre-Flight Operations Branch at the Manned Spacecraft Center in Houston during Apollo; and Lotzmann reports that Reyes, Wayne Stallard and others drew little cartoons on the daily schedules to make them more interesting. There it is. [Armstrong, from the 1969 Technical Debrief - "It suffices to say that we never did understand what was required to enable good comm while we were inside the cockpit, relaying through the PLSSs.

[Once Buzz has the valve open, he will leave it open until the cabin pressure has dropped to 3.5 psi. Let's see if he comes through any better now. A counter-weighted suspension device is bearing the weight of the PLSS although, evidently, a cable has come off its pulley. The First Lunar Landing NASA EP-73 . Prior to that it was relatively quiet. 108:21:50 Armstrong: Do we have a Go for cabin depress? The LM pilot , restrained by "golden slippers" on the LM porch photographs various components The other was, in training, we wanted to avoid as many activities as we could with the PLSS on our back, because it was very uncomfortable doing any additional exercise in one g.

(Long Pause). (Pause), 109:15:05 Armstrong: It's open.

And that can be very damaging, and I think that's happened in many cases. You would make small deviations just based on what seems appropriate at that time. Neil.
