Why The Engines That Flew On Saturn V Rocket Look Different In Museums

Click any button for sharing!


The F-1 engine is the most powerful single chamber rocket engine, and 5 of them were used to power the 1st stage of the Saturn V rocket. However when we see close up video of the engines lifting the rocket they look a lot different from the examples we see in museums. The detailed pipework is covered up by what looks like sheet sheet metal that’s been hammered into place.
This is insulation designed to protect the engines from heat radiated from their neighbours, and from hot exhaust gasses that get sucked up onto the back of the rocket.
If you want to buy a copy of the Saturn V Manual i showed it’s available on Amazon here:

    Conclusion museum should be classed as 18+. As they show their engines nude.

  2. Andre T

    I never noticed this before. Thanks for this very interesting.

  3. Chris Porter

    I noticed the lining during the Apollo 11 movie as well. It was something I hadn’t seen before even though I’ve seen multiple F-1 engines up close.
    @ScottManley, I assume you’ve had an opportunity to visit the Saturn V Complex at Kennedy. I spent at least an hour starting at the F-1 engines and had the neck cramps to prove it. I found a variance in the mounting and gimbal configurations between the different engines. Do you know if this was normal or if these engines might have been sourced from various revisions of non-flown test engines?

    You sir are a national treasure. I greatly appreciate the knowledge you share.

  5. Quaternary Tetrad

    Aye, I have the Saturn V Owner’s Workshop Manual, and I have the manual for the space shuttle and the Rolls-Royce Merlin engine, too!

  6. rybaxs

    OMG woow .. i feel like the trust is 1+1=3 and what is in my mind was 1+1=2 . i think museum dont like the asbestos coz it is dangerous to health.

  7. Johnathon Smithname

    Scott, good video as always. Could you do one on what held the Saturn 5 to the pad, what triggered it’s release. I am also curious about the swingarms, what detached them from the Saturn 5 and trigged the motion. I know it’s a tiny detail but I have always been fascinated with those subjects. Thank you for your video’s they have provided some really great info for me.

  8. Brass Tacks

    im going to the space and rocket center in huntsville al this july x3

  9. edoardo fantechi

    Beautiful video as usual! But I have one question: how come you owned a Fiat Uno?

  10. Mark Davis

    Just pulled out my copy of the Haynes manual! Never noticed the missing blankets before!

  11. RideNV

    Stoked my hypothesis of what and why it was was correct. Perhaps if enough people know about it and inquire, one of the engines will be retrofit accordingly. That would still leave us 4 exposed engines to oogle and marvel at on a full-scale example, while including a more accurate version for further edification.

  12. kneelz s

    Let me condense this for you and save you a lot of time.
    They were wrapped in foil and asbestos

  13. Mohamed Alfekie

    Thanks Scott too much for learning me about Saturn V , because my all past experience from Serji krloeiv rockets 🚀

  14. David Gray

    Vince Capone, who recovered the Apollo 11 Saturn engines will give a talk at Infoage in Wall NJ. On saturday April 13,2019 at 7:30. www.infoage.org for more information.

  15. Excelcior58

    I noticed these coatings as well. That documentary is amazing, so much detail. Need another week in IMAX! I didnt get to see it a third time :(

  16. Jdubb Whitelightning

    I’ve always been captivated by the exhaust flume to pay attention to that. Thanks for this info. I love your videos. Keep them coming.

  17. Eric Taylor

    We had those books as well here. I used one to rebuild my S-10 when I was 18.
    They are really quite good guides.

  18. Ross B

    Yeah i’m pissed its only in theater’s for a week and i just found out about it. I hope they plan to bring it back because the nearest place showing it is 2 hrs away,

  19. Brandon James

    See this in IMAX if you possibly can. It’s absolutely breathtaking. I had seen the footage of Apollo 11 that everyone has seen but much of this movie is new and it’s spectacular. And this is an unobtrusive film. No narrator and 100% archival footage. The Sound and small amount of music somehow added drama to the already-dramatic and was very well done.

  20. Rich

    There’s a whole cottage industry to upgrade your Saturn V model kits with the proper engines😃

  21. freaky767

    2:49 same thing occurs with the falcon 9 when you see those tracking shots.

  22. Sean McDonough

    3:39 – Also, _asbestos._

  23. MadEzra64

    First Man got it correct only because they used restored actual footage hehe BUT another great video Scott!

  24. Matt P

    Hullo ITS SCOTT MANLEY. Agressive. I love this channel. Nearly as much as Fraser cain

  25. galagachamp

    Thanks, Scott! The Saturn V model I’m building will be a little more accurate than it would’ve been, though you’ve also given me more work to do…

  26. mrwealthyhobo

    Hearing those powerful engines in the IMAX theater brought a tear to my eye, amazing movie thanks for the recommendation!

  27. mad zak

    wow, i want the enterprise one fix manual ) , my grandpa bought me manual like that and gave me the old Soviet one from 1970s, (you know few Russian cars just stayed the same as the 70s model except the fuel injection system) you can build a car from scrap with it )

  28. Cozy Unbound

    I lived in Huntsville for years and got to walk up to the Saturn V replica whenever I felt like it. Good times!

  29. Mark Stover

    Thanks for this…I always wondered why they looked different in the videos. I worked at Marshall, and still never heard about this.

  30. Matthew Sinclair

    Heh. I should’ve been expecting this after seeing your tweet. Always interesting content! Going to see Apollo 11 doc tomorrow!!!!

  31. glenesis

    Hi! Just found your channel. Thanks for the great video! I hadn’t noticed this. Very cool! I need to find that imax doc. Have a beautiful day!

  32. Architect_Blasen

    Haynes manuals are also present in the U.S. I’ve had one for every car I’ve ever owned. That being said, great vid!

  33. Rheinmetall1944

    Would love to see some more Saturn V footage. Maybe some history on the design as well! Great video yet again, keep up the good work!

  34. John F

    Thanks for that. I suspect most F-1 engines on display wouldn’t want to hide part of it under insulation. There was so much going on with them.The Saturn 5 was an amazing piece of engineering.

  35. Chiiin Thanos

    Going to watch Apollo 11 tomorrow! Thanks for recommendation
    Also saw you tweeting about the engines in Apollo 13 so I guess I kinda expected this topic. Great video as always

  36. sidewalkere

    Having seen countlesse videos and photos of the saturn V, i’m banging my head on the wall for never had noticed that insulation..
    Thank you, Scott!

  37. Jim Sackman Business Coaching

    I think the size thing that nobody really talks about is my ability in South Florida (200 miles or so away) being able to see the Shuttle take off – even during the day. I imagine the Saturn V launches were similarly visible. Night launches were spectacular. And there was this one day when we were going to lunch, looking up and saying: “Must be something wrong with the Shuttle.” (RIP Challenger).

  38. Robert Himes

    Scott I live 2 miles from Johnson Space Center in Houston. They have a a Saturn
    V on display. It’s impressive. The engine are huge. Amazing thing to go see.

  39. jameswalker199

    Haynes manuals are great, they even have a workshop manual for Thomas the Tank Engine for all the young, aspiring engineers.

  40. Ian Slatas

    I hadn’t noticed the engine insulation until I saw Apollo 11 in IMAX yesterday. Thanks for the recommendation! What a stellar film.

  41. Brian W

    I remember putting brakes on my first car back around 1980 (it was a built in 68), and my father warning me not to inhale the brake dust as it was full of asbestos. We spent quite a few years without a good replacement for asbestos, it really was an excellent insulator!!! Same with R-12/22, my father used to bring home cans of R-12 for $0.50 a can, and you could buy asbestos at any local hardware store. There’s no telling how much asbestos dust I inhaled as a boy, maybe some folks are just more susceptible to it than I was… Who knows, I’m 53 and in relatively good health :-) Great catch Mr Manley, thank you for the insight! I’ve watched Apollo launches many times and never noticed that :-)

  42. Laélien Rivière

    I didn’t know I needed this in my life.
    Yet I did.
    Thanks, Scott. Keep being amazing.

  43. Alan Tennant

    The covering also appears to occlude a lot of detail.

  44. Qasim Mir

    I’ve got a Haynes Manual of Concorde. It’s brilliant.👌🏼

  45. gnarlyandy1

    I watched apollo 11 because of your recommendation. I enjoyed it.

  46. Whoa Nelly

    I saw the movie. AMAZING. STUNNING. FANTASTIC.

  47. gajustempus

    explanation on why this foil is NOWHERE on display is quite simple – because you just said it yourself: Asbestos.
    It’s known to cause lung cancer. That’s why it’s removed from every place the public might be able to go to – as if the museum or wherever they’ve been shown would face quite some lawsuits claiming the asbestos caused cancer or whatever other disease. So it’s been removed…

  48. RufftaMan

    Hah, this “Owners Workshop Manual” for the Saturn V is laying beside my bed right now.. Great stuff!
    Haven’t read it all yet, but it’s fun seeing details you never thought about before.
    Great video!

  49. Joey Schwartz

    Thanks for the explanation. I’ve noticed this difference between flown and unflown articles since the early 1980s. I assumed it was simply the heat from the engines deforming the metal in some way, and never questioned it beyond that, nor gave it a second thought. Well done! Thank you for making these videos Scott.

  50. Stratowind

    Captions say: Although it’s Scott Manley here.

  51. ArcturanMegadonkey

    Seeing the flames come back when the rocket or shuttle went super sonic worried me!
    Great video as always Scott. Long time viewer, rarely comment
    Paul

  52. Richard Morris

    Great article, I’m a big Apollo fan being just old enough to have seen the moon landings on TV but had never noticed that the F1 engines were covered in an insulating shroud…..

  53. John Doyle

    Thanks,very informative, I just love Saturn V launches, hard core space porn.
    I like to see the engine in the raw without the Inconel and asbestos cover.
    Thanks again for your videos.

  54. GhostHostMemories

    Oh man.. now A13 needs to have a digital remastered version where they correct the engines…

  55. Devar

    Local IMAX cinema (only one in Western Australia) is currently not open. So no screening of this for me. SO ANNOYED.

  56. Fred Derf

    Terrific (as usual). Why can’t normal TV shows be this good?

  57. Duke of Norfolk

    I don’t know about The Haynes Manual for an F1 rocket engine. I’ll just watch your channel and listen to you ,thanks Big Scott.

  58. Dale Thelander

    They called the insulation layer “batting,” Scott.
    I got hold of a set of aftermarket “batted” resin engines for my 1/144 Saturn V kit.

  59. Mihir Gadgil

    I watched the movie 2 days ago after your recommendation. Time well spent! That ignition/liftoff audio was so great, I hope I get to experience a rocket launch in person some day..

  60. TheOzarkWizard

    Im absolutely amazed theres a manual for the Saturn V

  61. Chad Kent

    Most excellent information and you have a new subscriber

  62. Davld Bigman

    Hmm, never gave it a thought. Even standing just behind one in DC. Interesting.

  63. The Chopping Block

    1:12 I thought for certain you were going to say they look like they are made of hammered shit. Probably a regional colloquialism, but that phrase always makes me giggle.

  64. BMrider75

    Thanks Scott, excellent explanation and visual demonstration (as usual!).
    Thumbs up for the Haynes manuals reference. Smiles

  65. Kurt Weinstein

    I started watching this, paused to look up IMAX show times, and ran out the door. That was definitely worth rushing out to catch the second to last IMAX showing in my area.

  66. PirateMTH

    Scott, Thanks so much for your review of Apollo 11. It’s the reason I saw the film just a couple days before the run ended. Definitely worth seeing; and especially in the IMAX theater.

  67. LadyAnuB

    800 man-hours to wrap an engine? Yeah…no. I think this is the best reason that museum engines lack the insulation. Asbestos is the second reason.

  68. ComandanteJ

    I cant stop hearing “Koyaanisquatsi….” whenever i see those slow-motion Saturn V launch shots.

  69. dieselrotor

    Oh Man, when Ronco finally releases the portable “Home Time Machine”, I’m going back to hear those massive engines run !

  70. willys48

    I personally prefer the insulation not being on the museum pieces. Without it you are able to appreciate the intricate details of the rocket motor and bell assembly.
    I will always remember talking to Dan Hawkins, retired NASA propulsion engineer, at the US Space and Rocket Center. With a rightfully proud smirk he pointed up to the F-1 engines on the SA-500D and said, “Nobody else has those.”

  71. mjproebstle

    i always thot they were there to protect the surfaces from the salt air and brine from being close to thecocean while being worked up for launch after exiting the vab

  72. B.B. Does the Thing

    I regret never being able to seeing one of these launch. I wasnt born yet so its not completely my fault :P

  73. Yiannis Mantheakis

    “I grow old learning” – Socrates
    I never knew this detail. Thank for the insight Scot.

  74. pnutt

    So glad I took your recommendation on the documentary. Saw it in Denver with friends and was absolutely blown away. The launch sequence got me extremely emotional for some reason, it was just the most epic thing I’ve ever seen. Thanks Scott

  75. Joeylawn36111

    5:05 Don’t buy the Haynes Manual for the USS Enterprise. Most of it has incorrect data, because the book sourced it from Romulan Spy sources.

  76. TitanFallout

    I’ve read the Saturn V Haynes manual, very informative book.

  77. Don Guru de Bro

    Cause they are not on (fire)? ;-)

  78. David Muncaster

    I wonder if the fact that it was COVERED IN ASBESTOS is the reason that they don’t display that version :) But to be honest I like the look of the non-covered version better, shows just how incredibly complex rockets are.

  79. Cuzican Aerospace

    I have the Haynes manual for The Moon.
    No, really. It’s a stretch but the book’s not bad.

  80. jonathan lavezzi

    Make asbestos great again 😂

  81. Otto's Place

    I’m lucky enough to live about 2 hours away from the space and rocket center in Huntsville AL where the test stands and shake building are located. They also have an actual Saturn V rocket and Apollo Capsule. Very cool place to visit if you ever get the opportunity.

  82. CJ Carter

    I’ve been adding the insulation to Saturn V models for quite a while now (not that I make a ton of them). Finding clear pictures of the engines was an interesting exercise — especially before the Interweb references were fleshed out.

  83. Magnus Bergner

    Museum: “And this is our display of asbestos covered rocket engines.” Turns around to see every kid lifted of their feet by parents in full sprint away from the display.

  84. Steve Siegelin

    Chilton and Haynes manuals are in the U.S. They have been here for decades.

  85. Michael Grizzard

    OMG I can actually add something here!!!
    When on a Spacecamp Bivouac I actually asked about this – the reason I was given by senior staff is that the blankets were simply this: Asbestos.
    They can’t display an item with cancerous material for the public ;)

  86. Nazamroth

    Do you know what is even more interesting? Such details of everyday life and megaprojects as well, may well be lost to the future. A thousand years from now, we might have archeologists trying to figure out how the famous Saturn 5 in the museum was supposed to fly, since its engines would overheat from the mentioned effects, and the DIY thermal shroud mod would have been lost to the pre-digital era.

  87. Matt 68

    Probably because they are full of asbestos?

  88. Jerry W. Gilley

    I live in Huntsville and worked for the Space and Rocket Center for 9 years and helped design and construct his portion of the museum. I have also have spoken with his daughter and my wife works for NASA so I thought I would mention a two things.
    1. The way he and his daughter pronounced “Braun” sounds like “Brown” and he even wrote “Brown” on their mail box to try and get us to say it correctly. I confirmed this when I spoke to his daughter face to face for 45 min as we had dinner at an event honoring her father.
    2. Werner von Braun left his lunch box on top of the Saturn V Dynamic Test and is 363 feet tall on red stone arsenal and never went back to get it. He would eat lunch on top of the stand every day weather would allow to clear his thoughts. They used to take new hires up to the top to see it and to reflect on how their vision compares with Brauns. They stopped this now due to the condition the test stand is in now but still show a picture and ask you reflect.
    Just some info most people don’t know.

  89. How To Focus

    “Industry standard Werner Von Braun for scale” 😂😂😂 so understated. Well done, Scott

  90. Eric

    Guess I’ll be wrapping tin foil around the Lego Saturn V’s engines…

  91. Abdega

    It was made to look like duct tape so all the engineers would trust the engine 🙃

  92. Space Core

    Well, I guess they realised that asbestos isn’t good for your health didn’t they. Also, it looks much cooler without its blanket (or should i say hotter ? Depends on your viewpoint !)

  93. Kumquat Lord

    Ahh, launch camera E8, how I love your footage of the F-1’s starting up and lifting the magnificent Saturn V into orbit!

  94. Max Kopstein

    First Man got it correct because instead of making the close up shots using expensive CGI which would then just go through a filter to make the footage look old anyway, they just used the incredible close up footage that NASA engineers shot already for analysis purposes. Good choice in my opinion, but I wouldn’t give them full credit for getting every detail right in this case since it was just by default. Still an incredible film though (and after this I think I should go see Apollo 11)
    Edit:
    I had not yet seen Apollo 11 and so didn’t realize it was made using entirely real footage, my bad. Just saw it and oh my god it was awesome!

  95. Drauggen

    My grandfather helped design some targeting systems for rockets and was a huge apollo fan boy. He used to call the f1 at lift off the “the voice of God” he sat outside one night and told me by the time I had kids we would probably have cars in space. Well he was not totally off thanks to Elon. For what it’s worth you remind me of him. Even at 80 anything space would cause him to light up.

  96. Doug Ball

    Scott, as an aerodynamicist I feel the need to give you a minor course correction. The pressure behind a shock is higher, not lower. Supersonic flow, when encountering a protrusion into the flow (like the corner between the service module and the SLA) a shock forms to turn the flow. When the body turns away from the flow (like where the SLA meets the S-IVB) an expansion forms to turn the flow. The pressure behind an expansion is lower. So you are correct that the base pressure is decreasing, but it is because of expansions and not shocks. I offer this kindly because I find most of your videos and explanations spot on and thought you would like to know. Keep up the good work!

  97. Don Guru de Bro

    So even The F1 Engines are wearing Tin foil hats and they still tell us that there are no Alien out there!
    Unbelievable! ;D

  98. Ewan Murray

    I kinda like that they don’t have insulation in museums, it means you get to see all the amazing details underneath

  99. Sebastian Chan

    They probably also don’t want asbestos lying around museums anymore.

  100. Zero Spampls

    “Industry standard Werner Von Braun for scale” And the best Qutoe 2019 goes to Scott Manley!
