Merry Xmas!
That was always key to the story. No TARDIS no quick escape. It's the same reason the writers hated K9 and the sonic screwdriver, it was always too easy to get out of a spot. Both were destroyed. K9 would have gone waaaay sooner if he wasn't so popular. That would have made me a very sad lad though, I seem to remember even being pretty upset when Davison dropped the sonic screwdriver.
The Visitation. I think he said "it's like losing an old friend". Whereas precocious moi said it's like losing a handy tidy up the plot device
Still thought that story (Saward?) was excellent.
