The problem with the show is that it's covering so much in so little time a lot of interesting facts are left out. I did like the part about "underfueling" the LEM descent stage so the Apollo 10 astronaughts wouldn't try to land on the Moon. I was also suprised to see Neil Armstrong on the program.

My recollection (and the information from Mike Collins in his book LIFTOFF!!) is that the Apollo 10 lunar module was still overweight, which is why it would have been unsuitable for a lunar landing attempt. I had not heard about it being "under fueled" until this program, and I have failed to verify (at least on-line and in two books about the program I have) that this actually occurred. I would have considered under-fueling a bit risky, as if something went wrong with the "nominal" mission, it would be nice to make up for it by having as much fuel as possible to get the spacecraft out of some potential jam. Clear skies to you.
