[@MikeHarpe]

I think Kranz has a pretty good agent :-).

[@markholbrook3949]

I said the exact same thing!!! Gene Kranz deserves his popularity but many people don't realize there's other teams involved!!!

From the point of view of the filmmakers, totally recreateing the MOCR experience would make a very boring movie. The movie is fantastic, crisp, thrilling, very well made. However, for making it entertaining for the average viewer, they needed to gave up reality.

[@5Andysalive]

KRanz: In the control room upstairs, Lunney had completed the evacuation of the crew to the LM and was preparing for a small maneuver that would place the spacecraft on a path to return to Earth. After completing the Tiger Team meeting, I went back to the control room to get a status update from Lunney. Glynn was now concerned about powering down the navigation system. He had been advised by astronauts Tom Stafford and Gene Cernan, in the simulators, about the difficulties of performing an alignment while docked, using the LM optics. The navigation platform (gyros) is aligned using stars and a sextantlike device. Sunlight reflecting off the CSM made it difficult to recognize the navigation stars. The crew’s report that they could not recognize stars due to the cloud of debris surrounding the spacecraft further convinced Lunney that we needed to keep the LM computer and display system powered up until we completed the get-home maneuver. Then we could power down and coast back to Earth. The risk was high, trading electrical power to keep the computer and navigation system on line against the possibility that we might be unable to realign the navigation platform. Without a navigation platform we could not perform the maneuver to accelerate the return to Earth. If we ran out of power, we could not get into position for reentry. We were playing showdown poker; we needed to get a better hand. I tracked Aaron down and gave him this new complication, telling him that he should make it his number one priority. Aaron said, “I don’t have to run the numbers all out, but I can tell you that if you take this approach, you will have to power down to a survival-level, limited telemetry, a very late power-up for entry, and the possibility that some of the systems may fail due to the cold. It is going to be tough on the crew. Some of the systems may freeze up.” “John, the best judgment we have,” I replied, “says that we cannot realign the navigation system. I think this is our only option. Get on it!” Aaron’s problem just got a lot tougher. His group set up their camp in the support rooms adjacent to my home base in the data room. John Aaron would not return to the console until the final shift four days later.

[@passivate]

Absolutely riveting! I totally enjoyed this series. While listening to these recordings, one realizes how much we take for granted the computing power available today to automate complex systems and to perform real-time simulations which at the time of Apollo 13, was non-existent.

[@duster0066]

I was thinking in 2020 we might out smart ourselves, and depend on automation. When the electrons run out we would have a lost mission and crew.

[@AureliusR]

Actually, the computers they were using and the AGC were both exceptionally powerful. The AGC in particular was not a general-purpose computer, so the specs that people list regarding it (FLOPS, etc) aren't really comparable. It did a lot of neat tricks to do the complex math required, and because it was built from the ground up to be a guidance computer, the hardware and software people were able to co-ordinate and come up with a very optimized solution. It's really an amazing machine.

[@simonparker57]

Fascinating the different management techniques of Kranz and Lunney. Kranz's Frankenstein haircut and square jaw makes us think of him as a kick arse dictator, but his style actually comes across as more emollient than Lunney. He uses first name terms more frequently. He's definitely the boss, but he's happy to defer to the individual controllers if they can make a case. Lunney is quite prepared to show irritation with anyone not perceived to be pulling their weight. He snaps a couple of times if he feels someone is not providing an answer he feels should be available. In fairness, he probably has the more stressful task. Kranz is trying to understand the problem, Lunney has to fix it.

[@MaynardGKrebs-gv4vy]

Good analysis. Kranz was the type of manager that trusted his people and would back them even unto death if necessary. He basically told the staff when Apollo 11 was going to land. Make your call, I'm paying you to do it.

[@samuellawson7370]

Though he applies lots of pressure to his own controllers, Lunney is noticeably more patient and at times almost deferential to CAPCOM Lousma.

[@MartinHopkinson]

@user-du8rm1yq4c You’re quite right. As an ex-military pilot, turned airline Training Captain, I find it a very interesting exercise in what we now call ‘Human Factors’ training. Glynn Lunney would have taken some ‘feedback’ were he to have been debriefed nowadays! It’s interesting because the styles of Lunney and Kranz are exactly opposite to the outward impressions I imagine of their characters. That said, I have nothing but admiration for what they both achieved under extreme pressure.

[@bobwalton4630]

Lunney did not suffer fools but was also calm under pressure. So many times he seems on the edge of swearing or yelling but he keeps it together for the whole pressure packed shift. True leadership at its best

[@queenash2755]

You could hear it several times in part 3 of this radio loop.

[@Banana_Cognac]

Lunney was also one who everyone said was always 10 steps ahead of everyone else. So when he asked about a system, he would do so before that group had even thought of it. I agree, in some moments he's a little more punchy. But during his shift, they were under extreme time pressure to get into the lm, the CM powered down completely, the guidance xfer, free-return, lm power down, beginnings of consumable conservation. They had a ton of work to do during their shift.

[@sinclairjg]

Something to note is that Mission Control workers are often engineers and the Capcom is always an astronaut, I believe. You can tell when an order comes from Flight and Capcom questions it since he understands where the people in the capsule are and what they're probably dealing with.

[@5Andysalive]

He is expected to spek for the crew which can't be involved in every discussion as you hear.. Kranz mentions this several times in his book. And the flight directors also accept him in this role. I think Lunney and Lousma are the unsing heros who got the bad deal in the movie.

[@paulsarna5066]

@@5Andysalive I just knew Jack Lousma from Skylab, but he was surprisingly good here.

[@chipdeaton3484]

You are right..to a point. That IS the reasoning for CAPCOM being an 'astronaut', in the days of Apollo missions. But , Lousma was also an "engineer" with a BS in Engineering, before becoming an astronaut.

[@Banana_Cognac]

@@chipdeaton3484 an engineering degree was a requirement for at least Gemini, and I'm sure Apollo as well. I'm not sure if it was a requirement for Mercury, or if they just needed a college degree in general. As far as I can remember from an interview with Haise, he worked for a NASA contractor as an engineer before being accepted to the astronaut corps. Even Swigert helped design the contingency procedures for the CM. The movie made it seem like he was a complete rookie, but Swigert knew the CM quite well

[@jgunther3398]

lol. you can be sure everybody in mission control was an engineer, or physicist at least. the astros themselves were likely engineers + military test pilots since that was the formula for acceptance into the astronaut program. capcom is the only person who talks to the astros directly, he is an astro himself and the opinion was he could communicate best with the other astros

[@doubletap333]

any chance of the next loops being posted ? thank you so much for posting these 4, it would be great to hear the rest if you have it. regards.

[@5Andysalive]

Shame there isn't more. But towards the end the recommendations from the by then huge backroom staff, including several Astronauts in the Simulators, took over. The idea to leave the imu up wasn't improvised. It was thought through and simulated to make sure it was ok. As was every other major decsion after this point. So in a way the on-shift flight directors, while still in charge, weren't on the forefront of decision making anymore. 1:38:00 you hear Kranz delivering and discussing the plans for the imu to Lunney. And obviously nobody was "suddenly" suprised by the oxygen/co² levels in the damaged spacecraft(!) they managed. The movie claiming this, is an insult to the engineers and the astronauts. Nobody was surprised by anything after this. Too many eyes and brains were on the case.

[@knightrideshare4264]

In part 4 you can totally hear “the pilots” of the spacecraft knowing the situation and being frustrated with “the checklist” they have to go through. They know what they are doing and they have to trust NASA with the information to get home and yet still frustrated with the redundancy of the checklists. I respect the professionalism of astronauts that are “LITERALLY” stranded in space. (Outside of the Van Allen Belt) Big Stones!

[@schmetterling4477]

The bad thing about space is that you are on a known trajectory. The good thing about space is that you are on a known trajectory. The Apollo missions were designed with a free return trajectory for a good reason. I believe Apollo 13 had already modified this to a lunar insertion trajectory by the time the accident happened and they basically had to revert to free return using the propulsion of the LEM. They also sped up their return after they were around the moon. This may have been crucial to assure that the Apollo capsule had enough power and cooling water left for re-entry. All in all the physical restrictions to the spacecraft trajectories were so severe that the astronauts literally could not have gotten "lost in space" as long as they had some residual delta-v capability. That people are not as panicky as an outside observer might expect is because these folks knew physics and they trusted physics.

The skill of the capcom is remarkable . . . translating complex technical information from hard-pressed engineers into transparent and, at the same time, reassuring language for the vulnerable astronauts. Such and such 'oughta do the trick' . . . and so on. Had the capcom got the words or the tone wrong, the astronauts would surely have panicked.

[@garyparata2885]

Well, I don’t know about anyone panicking, but yes, Jack Lousma was CAPCOM here. The Apollo CAPCOMs all were astronauts themselves, and Lousma flew on the second manned Skylab mission three years after Apollo 13.

[@bigdrew565]

I do believe that this is the reason why the Astronauts demanded that one of their own communicates with the spacecraft from the mercury days. Panic? Doubt it. Especially jim Lovell.

[@5Andysalive]

And also he's not just talking. He's an active part, thinking and speaking for the crew. Quite firm and demanding at times. Fully respected in that by the flight director. That's also how Kranz describes it in his book. When they had the discussion earlier, about direct abort or free return (not leaving Mission control roomwhile on shift, like in the movie!) -- "I knew Lunney would fight to the death for the long return after talking to the troops in the Trench. Controllers clustered about the console as we talked, recognizing a decision was imminent. Bostick and Deiterich were joined by my FIDO, Bill Stoval, from the Trench. Lousma crowded in, representing the crews." ........... "Missions run on trust. Trust allows the crew and team to make the minutes and seconds count in a crisis. In the scramble to secure the command module, we didn’t have a chance to brief the crew or even get their opinion on the return path. In my mind I knew the crew would fight to hang on to the lunar module. I felt Lousma, as their representative, would speak out if needed." end quote. Of course going for direct abort would have been an insane risk. You'd have to cut off all other options before you could try it. I never heard were Lousma stood on this but he obviously was ok with that call, as were the astronauts. In all the com they never mention the direct abort option. That "trust" Kranz mentions obviously existed. And we'll never know if the SPS would have worked or not.

[@markholbrook3949]

Whoever implemented the role of CAPCOM when NASA was born was brilliant and understood the importance of developing a solid relationship between Ground and Crew!!

Actually, the astronauts were somewhat engineers to. They knew the machine they were flying very-very well.

[@saucerspecial]

You can tell Lunney is getting irritated with his Guidance officer. I don't blame that flight controller though. You can literally hear the stress and tension in the room from the accident. I recommend that anyone interested in further reading to obviously read Lost Moon (aka Apollo 13). There is more information and insight to the emotions and politics of NASA at the time.

[@sporg]

Hi Eric -- 1) They were never suffocating: the crew made an adapter to connect the square CM CO2-scrubbing cartridges to the round LM connector, which dealt fine with CO2 levels; the film 'Apollo 13' makes the timing a little more dramatic than it actually was (though the consequences of doing nothing would have been severe). It was water, not O2, that was the serious consumable problem: they never needed the PLSS O2. Interestingly, they did discuss cutting the suit tubes to suck the water out of the suits! (you can read this in the transcripts), but the astronauts turned that option down! 2) If you've ever seen the lunar suits close up, you can see how bulky they were -- and there were three crew in the cramped LM (the CM was only a few degrees above freezing), plus remember that they'd only have worn the outer layers: the inner suit was a mass of tubes shifting water around to cool the astronauts. There was little to be gained, and Fred Haise himself commented on this, post landing.

I understand why filmmakers have to make the film they need to make. Condensed story, making it seem more dramatic, etc. I bet the film makers of Apollo 13 worked very very to hard to make it accurate. Which I believe it is. But it is interesting to note that the drama of these real recordings comes from the quick, smart, educated decision making that everybody including the astronauts were making. They had very little time to figure it out. Very little time. In many ways the film Apollo 13 DID reflect that ... but it really was more about the story about the power up sequence. (Which to be honest I haven’t located yet in these recordings.) Some of the filmed sequences seem to be overly dramatic. If it WAS that dramatic for those guys .... you sure cant tell from their voices. They were coooool customers.

[@MrLacp]

Debbie, why do you "watch" these videos if you don't understand them? R didn't even read the title. This IS Apollo 13, a mission to the Moon, no shuttles, no teachers, there's even a film about it, starring Tom Hanks. No one died and that wasn't because you pray.

[@SDelta100]

I vote for giving Debbie a "pass" on this one. While she's clearly not into the technical stuff like most of us, she's at least tuned in to the "human" element, which is very much a valid part of the story. Also, I think it's premature to rule out the role of prayer (and more broadly, human consciousness + "interdimensional" physics [cf.,, Superstring Theory, "Dark Matter," etc.]) relative to how the players pulled all of this off. (For example, I'm reminded of the growing body of solid scientific research on prayer as related to health outcomes.)

His are the most fascinating sessions on the 13 transcripts: creating a power-up for the LM in record time, and dealing with errors caused by haste and fatigue. It was commented (by whom I can't recall!) that he dealt with it all "with the calm, distracted air of a parent getting several children ready for school"....

The above comment from Orange 70383 was generally disrespectful considering the gravity of the crisis that took place and the American heroes that were involved. Typical modern day ignorance. The only thing that Apollo 13 and LGBT's had in common was an eventual loss of power. How's that for an answer?

Wow, these replies are something to behold.

ulysses777x. These videos are amazing! I had to stop halfway through to comment. I cannot remember this Space Shuttle. I remember Apollo 13 that had a school teacher on it. Actually, that might have had a different name. How many people were aboard this Spacecraft. I am assuming by the caption that they did not make it. They are so close. How sad. Thank you so much for posting. I am still praying that they made it.

Mark Pierce Obviously a very long time!

+Debbie Lyons Yes they made it home alive. This was not the space shuttle.....it was Apollo 13. It was the shuttle that had the teacher on it. You should watch the movie "Apollo 13" by Tom Hanks from 1995. The Apollo 13 flew in April 1970.

dbreardon Or read up on it and find out what REALLY happened. (You won't get that out of that movie.)

[@dbreardon]

True, but the movie gives you an overall sense of what went on......certainly even more than the public got back in 1970. I was suggesting the movie because it is the simple way to go without doing a lot of searching and reading. But both will work :)

Debbie. You seem like a very nice, attractive, caring, and compassionate person. But, unfortunately, you're dumb as a bag of hammers.

Soooo, what happened to part 5. we know NASA had a habit of things going 'missing' : "It occurred at 8:09 p.m. EST, April 14. The S-IVB struck the Moon with a force equivalent to 11 1/2 tons of TNT. It hit 85 miles west northwest of the site where the Apollo 12 astronauts had set up their seismometer. Scientists on Earth said, "the Moon rang like a bell." "
