Mac: [very rapidly, with a thick Scottish accent] Thrust! I went over my calculations, hen, and I forgot the key element missing is thrust! Rocky: [after a long pause] I didn't get a word of that. Mac: Thrust. Other birds, like ducks and geese, when they take off, what do they have? [shouts] Mac: Thrust! Rocky: I swear she ain't using real words. Ginger: She said we need more thrust. Rocky: Oh, thrust! Of course we need thrust. Why, thrust and flying are, well, like this. [crosses fingers] Rocky: See, that's flying and that's thrust.
