The Tenth Planet - Episode 3

Maybe I'm just in a nit-picking mood, but I noticed several things in this episode. First of all, the person doing the titles clearly hasn't been having much luck lately. The first episode was attributed to "Kitt Pedler", instead of Kit. This episode was co-written by "Gerry Davies", not Gerry Davis. OK, and here's another thing. The crew quarters that Ben is held in has a ventilation shaft that leads directly to the rocket silo. Does this seem wise? What happens when the rocket launches? Then there's the second Cyberman ship landing. It lands in exactly the same spot as the first Cybership landed. What happened to the first ship? Did it explode or something? Because it's clearly not there. And on a bit of a sad note, it's unfortunate that the final surviving complete William Hartnell episode does not feature William Hartnell at all. The Doctor collapses right at the beginning, and is out of action for the rest of the episode. Shame.
