Episode One - Planet of Giants
[TARDIS]
DOCTOR: We're approaching a planet.
IAN: Which one?
DOCTOR: We shall soon see.
BARBARA: Ow!
DOCTOR: What's the matter, my dear?
BARBARA: I've burnt myself. It's hot!
DOCTOR: Oh, something overheating here. Just as well we're landing. Susan, check the fault locator, please.
SUSAN: Yes, Grandfather.
BARBARA: We're not going to blow up or anything, are we?
DOCTOR: Oh, no, no, of course not. It's just, well, there we were, in the late eighteenth century and I tried another frequency to side-step the ship back into the middle of the twentieth century.
SUSAN: There's something on QR18, Grandfather, and A14D.
(A klaxon sounds)
SUSAN: Grandfather! Grandfather! The door's opening!
DOCTOR: What's happening? (frantically flipping switches) Close the doors, please. We haven't materialised properly. Quickly!
IAN: What do you mean, close the doors?
DOCTOR: Don't argue, dear boy. It's an emergency! Close the doors!
