- Apollo 11 Technical Crew Debriefing - Part 1
Unedited tape of the technical debriefing given by the Apollo
11 crew whilst in quarantine.
The recording was transcribed into type, at the time, and this
is included as part of the record, to read along to. It should
be noted that the transcription does not always match the
tape recording exactly.
This tape covered pre-launch activities through the launch,
TLI, docking of the LM and SIV-B Slingshot.

Technical debriefings are my favorite transcripts to read through when it comes to a mission.
It’s the moment where one can truly capture that the men who walked on the moon weren’t just pretty faces in suits, but some of the most talented aerospace engineers (and lunar geologists) out there.
Watching the Artemis II crew “debrief” after taste-testing their future flight rations, however, showed me that hearing these debriefings - at least to me - is far more fulfilling than reading through them.
Couldn’t be more thankful to hear the voices of these men saying the words that one would usually be forced to merely read online or on paper. Thanks LM-5
More than welcome!
This is quite astonishing really. The crew sound more relaxed than any interview or press conference they did at the time. Astronauts doing their thing! What a great find LM5 👏👌
@@Richjwade glad you like it... more over the coming months
They don’t make them like that anymore.
So excited for more
This is amazing, thank you! I had no idea these recordings existed!
You are more than welcome!
This is possibly the best thing i have ever listened to in my entire life!!!
Another amazing piece of history we get to hear because of you!!! We'll done sir!!
@@johnboystrong315 thank you
These recordings are giving a new perspective of this mission...what a gem! Thank you for providing us these tapes!
@@nonamewithoutacause6465 you are more than welcome
Thanks!
Thanks Sergy, that is very generous
Wow what a fascinating piece of audio. After only ever hearing them on a radio they sound different from what I expected especially Neil. but enjoyed listening to what I guess is more casual conversation compared to briefings and press stuff. Good find excited for the whole series.
@@Madison-in-da-house thanks, glad you enjoyed it
Wow! What a find! I think one of the more interesting things people unfamiliar with the transcript will see here is the discussion over the problems Collins had with the trained procedure for doing the Transposition and Docking (T&D) around 1:07:00. For some reason rather than trusting the IMU in this procedure, the early lunar flights initially used the simpler accelerometer in the Entry Monitor System (EMS), a system that was designed for axial acceleration measurements during reentry. (The EMS panel is the oddball thing with the scribe plotter in the upper left-hand part of the control panel.) The idea was that the EMS would record the forward and braking thrusting maneuver delta-Vs and the Command Module Pilot (CMP - Collins) would use those numbers to determine how much to thrust when flying back to the booster. The EMS was prone to errors in this use in T&D for a variety of reasons, and Collins found the EMS gave him unexpected values compared to the simulators. (Later crews gave up on the EMS procedure and eventually just timed the brief thrust away, and then back as discussed here.) The second problem is that they wanted the CMP to see the S-IVB as soon as possible during the turnaround flip, so they wanted to flip in the direction that brought the S-IVB into the CMP's windows as early as possible. The CM computer was great at very efficient attitude maneuvers - better and more accurate than the pilots could do - but depending on the incidental attitude rates induced by the separation, the CM computer guidance might choose to flip the CSM in the "wrong" direction delaying when the S-IVB came into view by a few seconds thought critical to the maneuver. The workaround was for the pilot to manually pitch "up" to get the maneuver going into the desired direction for the window view and then give it back to the computer to complete the maneuver when the "8-ball" attitude error needles showed that the computer would complete the maneuver in the same direction. To Collins dismay, each time he tried to do this the computer stopped the maneuver he had started. As a result they used more precious fuel than desired during the turnaround and return.
THANK YOU! I've read the debriefs dozens of times, but hearing the voices is at a whole new level. And, you know, I always suspected that the steno people paraphrased the actual statements made on the tapes, and sure enough, there are tons of examples of that. So, while I've read this before, this is more like the first time getting the whole story, hearing it. THANKS!!!
@@DougVanDorn it definitely puts a different perspective on it. Just hearing the inflection in the voices is different to what I imagined before when reading the transcripts
This is the type of content I've always wanted to hear. Thank you!
@@Chatta-Ortega you are welcome
TYVM for the excellent work creating these LM5.
@@kenleibrick1390 you are welcome!
This is brilliant! Thank you again, Simon, for your efforts in putting these together. Very much looking forward to this series. An intriguing view into some of the finer details of a space flight.
@@CSM-LM you are welcome!
Thank you so much. This is absolutely fascinating.
@@andywalkerchannel you are welcome
Wonderful resource. thank you.
Thanks
Thank you thats really generous
This is SO COOL! Can't wait for the rest of Apollo 11, and maybe even more missions?
Incredible! Never thought we would ever hear these tapes or even if they existed anymore
@@mckeevertom1927 I did a good thing!
Omg...need the rest... I'll be waiting impatiently.
Fantastic listening - enjoyed every detail down to hearing the PA announcements in the Lunar Receiving Laboratory!
@@matthewstone5576 yeah that was a bonus!
Historical transcripts , I'd never seen this film before, thanks LM5
The film was made by me - I think you mean the audio?
Oh my gosh! This is a gold mine! fascinating stuff! Thank you!!
@@rickteklits6872 you are welcome
This is awesome.
@@gives_bad_advice glad you liked it
Thank you!
They don’t make them like that anymore.
@@SeligTiles they sure don't
This is really good . Hope we can get other flights too at some point.
Super interesting, thanks for posting!
@@Shuttlesource thanks Mike
That was fascinating… thank you for tracking it down!
@@tedcole9936 you are welcome!
Gold! Thank you.
@@cameron1975williams welcome!
Proper engineers talking about engineering stuff!
9:11 I’d have been sat there shivering with fear about how I’m going 250,000 miles up. Buzz “beach was nice”.
@@THEMathHacker-121 cool as a cucumber
Around 1:04:30 it sounds like they may have touched on a sensitive topic, and shortly after 1:05:10 or so it sounds like they mutually agree to stop recording with nonverbal communication.
Does anyone have insight as to why?
Just listened to the whole thing. Thank you. How many of these recordings will there be for this mission?
@@homunculus777 there are many! I can only ask for one a month at present so it's going to take some time to complete the series
5:29 "sehr gut". The german phrase for "very good". I wonder how many german phrases were floating around back then from von Braun and his german collegues in everyday use, if any.
Fantastic LM5!! How in the world did you locate this recording?
@@epgallinj222 they are all stored at the US National archive. As a researcher I can ask for a limited amount to be digitised. Saw the series and asked for this one!
Amazing to listen to. God these guys are cool! Ha.
Will there be a part 2?
@@oopiestevie4131 yes
Suits too tight was a problem many times.............. this crew should have insisted that that be corrected immediately.....it was not.
Buzz's voice sounds different then. Not as gravelly as we're used to hearing him
Only one quarter of the way through: is Mike Collins doing virtually all of the talking?
@@N_Wheeler well a lot of the start of the mission he was responsible for as the CMP
What date was this? How many days after landing
@@andyourbirdcansing64 31 July
This just dropped. Oh lovely 😊
@@basfinnis enjoy, it's a unique perspective
Thanks!
@@homunculus777 thank you, that's very kind
This is amazing.
@@smfield glad you liked it
