So, I’m just curious, but when does @jaredhead eat the RS-25 (with mustard)?
Because, OMFG, it turns out that water towers can fly really well. If you look at the video, the thing isn’t even wobbling even though it’s all being balanced on one madly-vectoring engine. It’s got to be as inherently stable as balancing a water bottle on your finger but they make it look easy. Cold gas thrusters seemed to do the rotation. The thing also clearly changed the fuel mix right at the end to reduce thrust.
