A long telephone discussion between Chuck Deiterich and his fellow Retro John Llewellyn, in which they discuss all the key planning meetings that are happening, and who needs to go to what.

Deiterich says that Jay Greene is going to the Data Priority Meeting but he's happy once Llewellyn offers to go too. "I don't think it would hurt anything... I could imagine a Johnny Mayer type [head of MPAD] bringing in data like he did yesterday... I got really bent out of shape with Greene... I says you weren't around yesterday before that burn, everybody with their plans..."

Once again, what a great idea. It's very generous of you to offer to do, and share, these.

I'd be happy to help with identifying controllers and double-checking the jargon where possible.

For Apollo 13, there's a lot of good action on the Retro loop from 137 hours onwards until splashdown at 143 or so. Retro leading the flight dynamics work at that point, obviously, because they were responsible for re-entry. That would be my first recommendation for Apollo 13.

Earlier on, the serious discussion of burn options on the FIDO loop seems to start around 063 hours and presumably runs up until the PC+2 burn at 079:30 or so (though I haven't listened that far yet).

But I guess if I were going to start anywhere with the FIDO loop I would start with Apollo 11. The descent is, of course, gripping, as is the immediate aftermath when FIDO is still trying to work out where they landed. Maybe from 101 to 105 hours?

Also of interest on Apollo 11 is the preparation for the TEI burn, because there was all sorts of hassle and miscommunication and rescheduling, with FIDO (Greene) and RETRO (Deiterich) as a wonderfully bickering double act. That runs roughly from 128 to 131 hours, although the post-burn analysis and bickering continues through to 135 hours.

Hope that's useful! I have pretty detailed logs of the sections I've listened through, but only in the sense I've noted down what I found amusing or interesting... not encyclopedic at all, just an aide memoire.

We all like hearing Lunney get ticked off. During the LM power transfer procedure, SPAN and EECOM posit the idea to FLIGHT of doing a main bus/battery procedure to verify that the main bus is working properly, effectively combining procedures. With little time to spare and last-minute input flooding in to change the procedures, he gets more and more torched.

Suggestions would indeed be helpful. It also helps to know the names of the controllers, although getting the names of people in the backroom might be tricky. I know the guy working the FIDO console is a Bill, but there are multiple Bills working FIDO for Apollo 13. I've done some digging around and I know the names of the folks on the EECOM loops, including in SPAN (Mel Brooks has the ridiculously deep voice), but that's about it.

Yes, any such transcripts would be amazing!

If you're looking to transcribe flight dynamics loops as well, I would suggest that the immediate aftermath of the Apollo 13 accident is probably not where the most interesting action is – having done a lot of listening to the FIDO and Retro loops myself, I could make some suggestions if that would be useful. But any transcripts would absolutely be welcome.

I admit one thing I find amusing about this conversation is Dr. Berry's musing about how the media "is not covering much of anything" with regards to Apollo 13, a mere six minutes before the incident that turned this into arguably the second most famous Apollo mission in history, and certainly one of the most widely covered shortly thereafter!

General Discussion / I can put together a transcript for EECOM loops

Hi there! Would there be any benefit to me transcribing the EECOM loops for Apollo 13 - for instance, starting at the beginning of Sy Liebergot's shift just before the accident occurred and then crossing into some of Clint Burton's shift - and then posting it in the "Apollo 13 Moments of Interest" board? I had been transcribing some of the shift and thought it might be of interest to some of the readers/listeners. There's a lot of interesting moments and discussions to be found in some of the flight controller loops, and having the transcript would be helpful in navigating through it. I have no problem putting it together, as I have both the software and equipment to run through it in fairly short order.

I'd attempt to transcribe the FIDO shift also, but as would be expected for anything in flight dynamics, there's a lot more jargon in there and in general it's a bit tougher to follow.

It has become apparent over the hours following the accident that power will be needed from the LM to the CSM in order to carry out crucial maneuvers for the PC+2 abort. Unfortunately, the procedure for doing this is becoming very lengthy, which FLIGHT Glynn Lunney comments on as TELMU gives his report to him.

Lunney later relays this to CAPCOM Joe Kerwin. Kerwin is already a bit skeptical about having the crew do any unnecessary procedures. Earlier, he feuded with EECOM Liebergot about doing extra cryo-stirs. Not surprisingly, he is very audibly frustrated at the lengthening of the LM umbilical procedure.

Especially given Kerwin, according to Sy, is very protective of the crew and frequently questions the decisions made by flight control if they aren't to the astronauts' benefits.

It's possible they were still trying to follow some semblance of a strict flight plan and chose not to use the blanket since it's meant for post-landing purposes and not for actual use during flight.

I heard this too. I was surprised and keep listening for this to be passed up. I have yet to hear the suggestion on air to ground. I wonder why Kerwin didn't communicate this to the crew since they were so cold.
