Dr. Rumack: Captain, these passengers don't have much time. How soon can we land?
Oveur: I can't tell.
Dr. Rumack: You can tell me, I'm a doctor.
Oveur: What I mean is, I don't know.
Dr. Rumack: Well can't you take a guess?
Oveur: ...Not for another two hours.
Dr. Rumack: You can't take a guess for another two hours?
Oveur: No what I'm saying is we can't land for another two hours.
