Listening to the Apollo 11 landing Flight controllers loop and the capcom/Eagle loop shows up the really bad 'tripping over each others words' that went on during the landing. These portions are edited out of the 'official' documentaries of the landings, probably because it sounds such a mess. There are examples where capcom Charlie Duke starts a sentence, then about a second later Neil or Buzz starts talking over him, then stop mid sentence to listen to what Charlie was saying. In the meantime, Charlie stops talking to listen to the communications coming from Eagle, not wanting to interupt. It all sounds comical, and so unslick, it makes you wonder how they didn't get into such a mess. You've also got the data delay, even longer than the voice, as it had to be processed, and sometimes got relayed to mission control via a different route. Here, the astronauts would call out an event, and the controllers would take a few seconds to confirm. If you go to the Apollo Archive site, you can download the .rm file for yourself to see what I mean.
