Re: Most fuel gone after 400 miles
If memory serves, the Saturn V final stage put the whole shebang into trans-lunar orbit. The Command Module then separated, turned around to dock with the Lunar Module, pulled the LM away from the Saturn V stage and then coasted to the Moon, where it looped around. The Command Module motor fired over the far side of the Moon to slow them down into lunar orbit. The remnant of Saturn V was kicked into a different orbit and is still going around the Sun.
