I have looked for quite a while to find this out, and as yet have not been able to work out the answer.
On the Apollo missions 10 to 17 the CSM had to turn round to pick up the lunar module between leaving the Earth orbit and the moon orbit. The CSM would depart from the lunar orbit module, travel out "some distance", then do a 180 degree flip and pick up the lunar lander craft. In the cartoon style pictures, it looks like it is done immediately, however I can't imagine that would work easily!
So how far out - in feet or metres - did the CSM travel before turning round? Was it the same for all missions, or was it different for each one?
