Susan Foreman:  We 've left _ 1963 _ .
The Doctor: Oh , yes , undoubtedly . I 'll be able to tell you where presently . Zero ? That 's not right . I 'm afraid this yearometer is not calculating properly . Hm ! Well , anyway , the journey 's finished . What are you doing down there ?
Barbara Wright: What have you done ?
Ian Chesterton: Barbara , you do n't believe all this nonsense .
Susan Foreman: Well , look at the scanner screen .
The Doctor: Yes , look up there . They do n't understand and I suspect they do n't want to . Well , there you are . A new world for you .
Ian Chesterton: Sand and rock ?
The Doctor: Yes . That 's the immediate view outside the ship .
Barbara Wright: But where are we ?
Ian Chesterton: You mean that 's what we 'll see when we go outside ?
Susan Foreman: Yes , you 'll see it for yourself .
Ian Chesterton: I do n't believe it .
The Doctor: You really are a stubborn young man , are n't you ?
Ian Chesterton: All right , show me some proof . Give me some concrete evidence . I 'm sorry , Susan . I do n't want to hurt you , but it 's time you were brought back to reality .
Susan Foreman: But you 're wrong , Mr. Chesterton .
The Doctor: They are saying I 'm a charlatan . What concrete evidence would satisfy you ? Hmm ?
Ian Chesterton: Just open the doors , Doctor Foreman .
The Doctor: Eh ? Doctor who ? What are you talking about ?
