There are 26 incomplete Doctor Who stories, with 97 episodes from the first six years of the programme missing. Shit, I'm never going to get to see The Macra Terror, am I? ;_; To give some sense of scale, Star Trek: TNG only ran 178 episodes, so you can see why this really sucks donkey balls and why no one has forgiven the Beeb. All missing episodes are from First and Second Doctor stories - check out all the pink and yellow ones on this page. Thank god for the Animated Second Doctor, huh?
