Re: Asa!!"
Actually they did three separate burns using the LEM, although only one was highlighted in the movie. The first one was done before they even got to the moon. It was done to get them back into a free earth trajectory. The second one was done after they had come around the moon and where headed back to earth. It was done to speed up their return because they were going to run out of provisions. The third one (this is the one highlighted in the movie) was a corridor correction burn because they were shallowing up on their return trajectory. That was the one they had to do with no guidance computer because they needed to save electrical power. It seems I remember reading they made have even made a 4th burn at some point, but I can't be certain about that.
