Which way is up?
It's not about gravity. It's about thrust.
The floor is labeled on the prints. It doesn't talk about thrust.
It's easy. Down is that way, so the floor is that way.
I chose to believe my view of the floor is correct.
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.
