Neil Armstrong: You're down here and you look up and you don't think about it too much. But space exploration changes your perception.
Deke Slayton: We've got this under control.
Janet Armstrong: You're a bunch of boys making models out of balsa wood! You don't have anything under control!
Neil Armstrong: That's one small step for man, one giant leap for mankind.
Neil Armstrong: I don't know what space exploration will uncover, but I don't think it'll be exploration just for the sake of exploration. I think it'll be more the fact that it allows us to see things. That maybe we should have seen a long time ago. But just haven't been able to until now.
Janet Armstrong: What are the chances you're not coming back? Those kids, they don't have a father anymore! So you're gonna sit the boys down, and prepare them for the fact that you might never come home.
