@watcherzero5256 Letting the tanks pull a vacuum would have been a major oversight, because then it gets harder to pump the fuel out. If you turn a bottle upside down and don't press on it, you see the fluid come out in "jerks" because atmospheric air has to enter the bottle and bubble into the empty space before it can fall out. It's also easier to DIY a system that pressurizes the tank instead of using turbopumps. You're literally just using the inert gas to push the fluid out. Plus, all that is meaningless when they mentioned that the "fuel tank" had rockets attached to the bottom. Not combustion chambers. Rockets. It was probably only solids that were used.
