Watched the Apollo 11 movie on CNN (was in theaters earlier this year). The perplexing part to me was:

The lunar propulsion rocket had to detach from the main rocket, then attach to the lunar lander. Then, the lunar lander had to get off the moon, enter the moon's orbit, and re-attach to the propulsion rocket to get out of orbit back toward Earth.

That seems unfathomable.
