> Given the huge risks involved, a lot of different parties planned and scripted for the possible bad news. The truth, though, was that there was no Plan B. If things went sour, there was no way to fix it, and everyone involved knew it. As Christopher Klein put it, “Under the worst-case scenario, NASA planned to end communication with the [Apollo 11 crew], leaving them to either run out of oxygen or commit suicide with no further earthly contact.”

That's seems fantastically cruel. You'd think they would at least let their families radio them for some time, to say goodbye.
