Helix: The floor is labeled on the prints. It doesn't talk about thrust.
Sam: It's easy. Down is that way, so the floor is that way.
Helix: I chose to believe my view of the floor is correct.
Sam (thinking): Oh, sure. Helix can ignore which way is down and get away with it. When I do that, I pay for it every single time.
