And it's highly possible that had it not been for Armstrong's skill, nerve and intuition in dealing with the 1202 errors and his manual guidance of the LM onto more level terrain (as the minimum ascent fuel level inched ever closer), Apollo 11 might have been a disaster.
Quite likely.
It's fun to note the difference in presumption between Americans and Soviets. Some Americans said the Apollo spacecraft had to be remote-controlled because crewed space travel was beyond the technology. Some Soviets, in contrast, said that Soviet automation technology was deficient, therefore the remote-controlled Lunokhod rovers secretly had little KGB midgets inside them to drive them.
It's important to remember that the point of Apollo was, "to land a man on the Moon and return him safely to the Earth." The primary goal was a
crewed landing. If it's mandatory to have a human aboard, then it's smart to make that human an integral and important part of the overall system instead of just "Spam in a can."
It's also important to understand the Apollo 11 mission objective: To perform a manned lunar landing and return. The bar was kept absurdly low so that the U.S. could claim Kennedy's goal. Even if Armstrong and Aldrin had immediately lifted off without even getting out, the mission would have been deemed a success according to its objectives. That was held in abeyance in favor of the more exciting
possible mission activities such as photography and sample collection.
And others noted technically that the way we number years means that 1970 would be part of "this decade," so if Apollo 11 failed they still had another year and a half to try and still meet Kennedy's goal.
Finally, someone quite recently found in Pres. Nixon's papers the speech written for him that he was to have read if the crew had been unable to take off from the lunar surface. It had the expected platitudes, language like, "They came in peace and now they will have to rest in peace." It was accompanied by a sheet describing the protocol for radioing the last goodbyes, etc.
Capricorn One notwithstanding, the point is that you don't set up those contingencies for something you're faking. If you're faking it, you know how it will come out. You don't need Plan B options like downgrading the mission objectives, claiming more time, and contingencies for national funerals. If the more you dig into the history, the more you uncover stuff that a real mission would be thinking about (even if not made public), and the less you find things like, "Here's what to do if we get caught," the more your history is real.
