Yes, there were aspects of the Manhattan Project that were compartmentalised where workers in industry made components for the bomb blissfully unaware of their function and final destination. Those making the explosive mechanisms and enriching the uranium and plutonium knew the destination of their labour. There is one difference. The Manhattan project was a strategic secret to end the most destructive war in history.
That difference is even more pronounced. The Manhattan project had an obvious point at which everyone working on it knew the secret would be blown:the moment that weapon is deployed it's not a secret any more. Yes, some of the technical details may be kept confidential, but no-one working on the project needs to take the secret of the project's very
existence to their grave any more because the whole world happened to notice when two major Japanese cities were wiped off the map with one bomb each at the end of the war. The guys flying the B-29s that dropped them don't have to lie about it now. Oppenheimer didn't have to keep his involvement quiet and give a deathbed confession (though honestly he may have preferred it if essentially everyone didn't know him as the father of the most destructive and deadly weapon in history once the war was over).
The Apollo hoax would have to be kept secret for decades, in the face of constant developments and investigations. NASA had no way to guarantee the hoax would not be discovered in ten, twenty, thirty years, or even during Apollo 11 itself, and there is no point in the future where the secret can unavoidably come out.
They present the notion of the numbers involved in the production of the EVAs as being numerous.
This is where the HB arguments always fall down. They never appreciate the number of people who
have to be involved in the first place, even before trying to suggest how many have to be in on the secret.
Nixon couldn't keep a lid on Watergate.
I wasn't surprised to see Tim fall back on the old 'tricky Dick' argument. Again, they never understand how the project works, and how much of it was actually complete before Nixon was even running for president, never mind sworn in and in a position to start making decisions about NASA. He inherited a mature project from a political rival. Why would he, on discovering it was fake, continue along that line rather than just use it as ammo against his opponents? On the other hand, given a mature project that was about to achieve the amazing goal of the lunar landing, he gets to bask in the inherited glory that comes with being in charge at the time when all the really hard work has been done and the bit that is really going to make the US (and him) look great will happen anyway whatever he does.
Now, there are those CT's that claim that the astronauts were launched into LEO, but the trans-lunar flight part was not possible. That still means all those people involved in the building the large rocket that we saw on our screens are going to know the other part of their rocket did not go.
And that anyone who happened to look up would notice the Apollo spacecraft in orbit. Most HBs have never actually used their eyes to examine the sky and see just what is visible there. Hell a load of them claimed that blank areas on Google Sky or on images of the Moon were evidence of a cover-up, apparently blissfully unaware that there is an
actual sky they could look at, and an
actual moon that telescopes will allow them to see in detail with their own eyes!
I'm sure Jay can tell us more about the level or project integration, and if one part of the space vehicle did not work as advertised, then people in the other part of the project were very quickly going to know.
Most HBs don't even understand that NASA is not some big organisation that did all the work. one HB some years ago proudly proclaimed his credentials included work at a couple of aviation companies, and had no reply when we asked him to check with his colleagues and their records archives about the work done on the parts of the rocket and spacecraft built by some of those companies and ask why they continue to lie about it if it was all faked....
