This episode captured how wonderful the apollo 12 crew was. History often overlooks them because they were wedged between the famous 11 and the infamous 13.

Beano and Pete are so underrated. Gordo is almost unknown. I love this scene. Alot of it is straight from the mission transcripts. 'Try SCE to Auxiliary' ' FCE to auxilary, what is that?'' xD
@davecoalwood9487 Me and my daughter who was 6 at the time went to meet him and Buzz Aldrin at a small con in 2014. We had a nice presentation of all his artwork, and had a photo taken. Buzz looked thoroughly bored throughout but Al took his time to say hi, and even took his time to shuffle my daughter around to ensure a nice symmetrical shot. I ended up feeling ignorant because i was genuinely not prepared to engage with a legend.
Interesting side note, actor Paul McCrane (as Pete Conrad here) played world class prick Dr.Robert Romano on ‘ER.’ There was a model of the Saturn V rocket sitting on the desk in Romano’s office on that show’s set.
Staging looked really good, in First Man they leaned forward and the crew cabin in side the command module was grimy when they were brand new with a new car smell.
Al Bean was my favorite Apollo Astronaut. Even though it was Neil Armstrong who got me excited enough to kick hard enough so my mother could feel it for the first time.
Imagine if they had a different astronaut on the ship that day who didn't know what the SCE to Aux is. Could have come down with the flu and the whole mission would have been lost
Yes. As Lunar Module Pilot, his job was also basically the flight engineer for the command module, so all the controls for the electrical system were on his side.
I would’ve preferred that the series had dedicated episodes for Apollo 10 and 16. It would have been interesting to see how they would have portrayed John Young.
Nothing actually malfunctioned except for the instrumentation. Everything was still working fine. The signals telling the interments what to display was interrupted. What happens when a rocket loaded with several tons of rocket fuel is struck by lightning? Not much it would see. I would have expected a spectacular explosion, bigger than what happens when you launch a Space Shuttle in cold weather. They were damn lucky I think.
Never heard of a thing called a Faraday cage?? Anything made mostly out of metal tends to act as one when when hit by Lightning. Its the stuff not made of metal that reacts badly to lightning strikes.
Hmm. It was indeed more than instrumentation. The command module lost its guidance platform and some other systems that had to be reset and realigned once in orbit. Fortunately the Saturn V had its own guidance computer which was not affected by the lightning strike. Usually the command module guidance was backup to the Saturn’s guidance in the event something went sideways.
@@BFlyer Which in this case, it did. The guidance system relied on other instrument readings. When they went off line, the guidance system also went off line.
@@xponen In fact they think that the Saturn 5 actually created the lightning in the first place as it climbed through the cloud and the static charge it built up discharged down its exhaust plume.
I always wondered why the lighting strike didn’t activate the abort system

Saturn V rocket was rated for "all kind of weather" the computer was not damaged nor the instrumentation but rather batteries that powered the CM computer and transmitted all telemetry data suffered a voltage overload which throw them offline. But the Saturn V had an internal computer that was not affected by this. That's why it did not initiated an abort procedure
SCE is the Signal Conditioning Equipment. Basically it takes all the measurements around the capsule and converts them to a uniform (0-5V) voltage scale, which are then AD converted, encoded and transmitted to the ground. It had two power supplies, the main one, and the redundant (AUXilary) one. The lightning strike tripped the overcurrent protection of the fuel cells (they were confused by inducted currents etc.), which let the CM fall back to battery power. The batteries weren't capable of powering ALL the systems running during launch, they were meant for the reentry configuration. So the voltage sagged somewhat. No system had an immidiate problem with that .. except the SCE main power supply. It couldn't cope with the low input voltage and therefore all the output voltages were wrong .. but in a particular pattern, which John Aaron had already seen once during tests and remembered what it meant. So they switched to the redundant (AUX) power supply, which was of different construction and worked at lower input voltages, too. With good telemetry, they could confirm that the fuel cells breakers were errornously tripped, just switched them back on and almost everything returned to normal, the other problems could be sorted out in Orbit before TLI. There was some worry that the parachute explosives were already fired, which would make them fail to deploy while landing .. but they basically went .. "If that's the case, they are going to die either way. There is no reason not to visit the moon beforehand."
@@VintageTechFan i have heard about the parachutes could be a fatal kind of problem in apollo 13 too, how come there wasn't a reserve unit of parachutes, with its very own separate battery in the apollo missions?
@@dhlhthriwdhskissos9606 There were 3 parachutes, 2 of them were sufficient for a safe splashdown (that was, unintentionally, confirmed during Apollo 15). Parachutes of the size needed are big and heavy. As far as I know, they were actually packed using hydraulic presses to save save. So, a complete reserve set wasn't possible due to weight and space restrictions.

Fred Haise was the back up LMP on Apollo 8. Slayton didn't think Haise was ready for prime crew on 11, so Collins got the CMP slot when he returned to flight status and Aldrin got the LMP one. Seeing that Aldrin knew the launch part of a CMP duties already, they kept him in the center seat for the Apollo 11 launch.

Apollo 12: I've had the longest list of malfunctions that anybody has ever seen!
Apollo 13: Hold my oxygen tank...
This might be the best comment I have ever read
Actually, Apollo 13 Had a smaller list of abort malfunctions
Apollo 10: Sorry for giving that to you, 13. Want your old one back? Oh wait, it already burned up.
Channenger accepted.
Apollo 1: Hold my Command Module...
I love when you listen to the actual mission audio of the launch you can hear the crew literally laughing all the way into orbit
This episode captured how wonderful the apollo 12 crew was. History often overlooks them because they were wedged between the famous 11 and the infamous 13.
No mate, even a grassroot like me knows of the splendor of Pete's crew :)
"SCE to AUX."
When an ENGINEER and a TEST PILOT come together in PERFECT SYNERGY!!
And THAT, gentlemen, is how you do that.
RIP, Beano.
It's just so nice seeing people here in the comments being happy and celebratory.
You guys and gals rock.
“I know what that is!”
Al Bean - you sir are a steely eyed missile man!
Mad kudos to the 2 people that saved the mission from this incident:
John Aaron for recognizing what he was seeing and knowing how to respond
Alan Bean for knowing what that switch was and where to find it xD
My all-time favorite episode followed by "Spider."
Beano and Pete are so underrated. Gordo is almost unknown.
I love this scene. Alot of it is straight from the mission transcripts.
'Try SCE to Auxiliary' ' FCE to auxilary, what is that?'' xD
This just came up in my feed - yep, time to dig out that box set and watch all 10 episodes again.
RIP Al Bean because of you NASA has their lightning rule.
He was a real sweet old man, a warm and welcoming soul. I had the pleasure of meeting him in 2014.

Sure Apollo 11 was historic, but gees Apollo 12 would have been FUN - pressure off, and Pete on-board = never a dull moment.
Favorite Apollo mission and crew. Extraordinary men- As cool as they come.
Funny how this has Dave, a comedian. Considering the real crew laughed all the way into orbit.
HBO and Hanks did it right. Nothing else even comes close.
kepler240 Thought the same thing, they were right on the line with the technical accuracy. That's hard to see in Hollywood!
Absolutely correct! Nothing like that mess First Man.
@@MarvelousLXVII yeah, I couldn't believe how that movie made the white room and sterile cockpit look like a dirty kids room
John Arron... Man I hope they gave that guy a raise. He was worth it!
Humanity's greatest buddy road trip

" I know what that is!" Lol
Apollo 12 had serious comradery! These guys worked hard together!

The grime was such a glaringly bad decision, it still makes me angry.
RIP Al Bean 😢
Paul Park he’s up there with Pete and Dickie now. Go Navy. RIP Beano

Al Bean, you're going to the moon !
This is why you don't launch rocket in bad weather unless you wanted to tempting fate
Mission control: It's not possible.
Al Bean: No, it's necessary.
Great dramatization. Now if only the actor playing John Aaron had donned a Southern drawl...
RIP Al Bean
wait for staging All. Damn, can't you do anything right? Oh, never mind
ctr-alt-del
go for orbit.
A great series.
Imagine if they had a different astronaut on the ship that day who didn't know what the SCE to Aux is. Could have come down with the flu and the whole mission would have been lost
When in doubt. SCE to AUX. "The was one hell of a sim!"
So the Saturn 5 became a lightning rod?😮
RIP Al Bean.
all a bit faster all abit more hollywood. but nice as a visualisation of what was going on.
John Aaron is so underrated
Nooo he is not!!! He's only not well known - but we know of him!
my favorite scene is the series
Oh no... that's gottta be "yeah, i hit it with the hammer!"
It was actually hit by lightening twice during liftoff
And they said that in this video.
Was that Bean who did the SCE to AUX?
Yes
Yup
Yes. As Lunar Module Pilot, his job was also basically the flight engineer for the command module, so all the controls for the electrical system were on his side.
Al Bean is the coolest of the Astronauts.
Should've dedicated an episode to the UDT Frogmen who did the splashdown recoveries instead of wasting one on the reporter.
I would have loved that. (late reply I know)
Yeah, could have swapped it out with the wives episode.
I wouldn't have had oppositions for a 13th episode

@@erictaylor5462 Planes get hit by lightning all the time, yet we don't see them explode in fireballs. There's no grounding when you're in the air
Lightning hit the exhaust trail of the rocket and struck the rocket? Wow, space technology is mind boggling!
no, lightning hit the rocket first, then it flow thru the exhaust trail to the ground.
@@xponen In fact they think that the Saturn 5 actually created the lightning in the first place as it climbed through the cloud and the static charge it built up discharged down its exhaust plume.
@@richardvernon317 The exhaust gas is ionized and therefore conductive. They basically build a lightning arrestor reaching all up into the clouds.

Okay, excuse me. In the movie "Apollo 13", the CMP sat in the middle for blastoff, then sat in the commander's seat for splashdown.
