    It took months before NASA would even call Apollo 1 "Apollo 1" it was just Apollo-Saturn 204. The wives and crews had to fight hard to get that.

      Yeah that always confused me. Clearly the crew referred to AS-204 as Apollo 1 as proven by their crew patch on their suits. I guess it is like SpaceX referring to the demo-2 spacecraft as Crew Dragon while the astronauts called their ship Endeavor.

      The Apollo 1 crew gave a photo to Joe Shea, the Apollo program manager in Houston. The photo showed them putting their hands in prayer with the caption "It isn't that we don't trust you, Joe, but this time we've decided to go over your head". The program was so far behind that NASA and the contractors had to push hard to meet deadlines, and that inevitably meant cutting corners.

      @@cdmccul A quibble, Rockwell didn't acquire Collins Radio until about 1973. My dad also worked at Collins in Cedar Rapids during that time, albeit not directly on Apollo.
      When Rockwell bought the company, Arthur Collins moved to Dallas. Part of the deal was he could bring along a dozen engineers of his choice. My dad was in that group. He said they were working on some interesting things. But, eventually, they figured out that Arthur had lost the drive to turn any of it into actual shipping products. They all ended up moving on over the next several years.

    As a former technician with a NASA contractor that supplied spares in support of the lunar modules I very much appreciate your bringing the program back to life. My fondest memory is that the contract was "cost plus" meaning we worked until physically and mentally impossible to go on, "partied" ourselves to sleep (rarely at home) and then did it all over again. It was an amazing effort.

      I worked at the Roger B. Chaffee Planetarium while in high school. We had many of the original investigation documents of the fire in archives that I read carefully. It was a gruesome thing. Pressurized pure oxygen fires burn very hot. However, after the pressure burst the inner cabin wall on the right-hand side at after approximately thirty seconds of being fed by a cabin atmosphere of pure oxygen the now fed by outside atmospheric nitrogen-buffered ambient air, the fire decreased in intensity and started producing large amounts of smoke that killed the astronauts. They lost consciousness because of a lack of oxygen which sent them into cardiac arrest. They died from asphyxia due to the toxic gases from the fire and burns contributing to their death. Roger Chaffee's couch was found in the horizontal position, with the lower portion angled towards the floor. His helmet was closed and locked, his restraints were undone, and the hoses and electrical connections to the suit remained connected. As he was farthest from the origin of the fire, he suffered the least burn and suit damage.

    Being a nerd, I knew *of* many of the things in this video (but definitely not in near the amazing detail as you laid out). But the thing that I had NO idea about and really surprised me is the "dual gas/bleed-out" system. That's fascinating!

    • @JMChladek
      @JMChladek 3 года назад +2

      It sort of grew out of the system used in the X-15 and some other high altitude rocket plane programs. On the X-15, the pilot was breathing pure oxygen in the pressure suit while nitrogen was used in the cabin to mitigate the fire danger, partly because the X-15 had the pilot sitting just in front of the fuel tanks.
      In orbit, pure oxygen at 5 psi doesn't cause fire to burn much faster than oxygen/nitrogen at sea level pressure. Plus convection acts a little differently in zero gee.

    • @root42
      @root42 3 года назад +1

      Who knows. Maybe Block 2 would have had other issues. As mentioned a lot of the disaster was attributed to miscommunications and not implementing of changes to the vehicle. Also the fire wouldn't have happened, or wouldn't have been nearly as bad if they had used the mixed nitrogen/oxygen atmosphere as was used during the launch of later CMs. This still leaves the deathtrap of a hatch of course, and that might have still been disastrous. But as always: hindsight is 20-20, so it's easy to say today how it should have been.

    The Apollo hatch re-design, probably a most fascinating story of those that designed and built it. Story is there, I'm imagine a two hour youtube video with interviews of the engineers and the machinists involved. Engineers that argued during all-nighters, machinists doing their damndest to not screw up a fabrication or assembly.
    Interesting mention of the book "Apollo Pilot." Michael Collins in his 1974 book "Carrying the Fire" summarized various astronauts and wrote of Donn Eisele, "Eisele who? Lost in the shadows of Wally Schirra's fame."

    36:00 - Learned something new. I thought after Apollo 1 ... subsequent Apollo cockpits ran a mix environment throughout flight...not that it gradually went to pure Oxygen during launch.

      When the Apollo 1 backup crew (Schirra, Eisele and Cunningham) arrived at Ellington and were told of the fire by Bud Ream, Cunningham's first comment was, "Thank God it happened on the pad.". As an engineer, he understood that a ground based accident secured the chain of evidence that would lead to a cause and then a solution.

Since the Block 1 was designed with Earth Orbit Rendezvous in mind there are substantial changes between them. Especially in the case of the O2 storage and fuel cell systems that caused the accident on 13.

    Apollo 7 had a few “Block I” pieces, such as the Couches.
    Lunar Orbit Rendezvous (LOR) was originally proposed by John Houbolt,
    using the Saturn C-3 launcher (1961-1962).
    The Saturn C-4 and C-5 designs came as Lunar launcher simplification (1962-1964).

    I would like to know what information you have if any on AeroJet General Corporation from the mid to late 60's. They manufactured the engines for Mercury and Gemini. My dad worked there till mid 60's when NASA decided to have the engines built elsewhere. As far as I know they also built engines for the Redstone and other high profile programs and probably some not so publicized. The layoffs in the 60' s at the Rancho Cordova plant was devastating to a lot of us!

    CAN I SUGGEST A VIDEO THEME !!!???? Given so many of America's brightest brains focused so hard on making the Apollo programme work. The simple question is: what did they overlook? For example, is there any record of when Neil Armstrong arrived back home - him debriefing various teams and saying, "Well this didn't work well and that didn't work well. We should reconsider...."???
    .
    And other Apollo missions? (we know about Apollo 13 - but what about others?)
    .
    I'd be impressed to see how, the best brains went over every tiny detail yet the reality is the true test.
