stuff that’s hard to do (crushed like a soda can)

The SpaceX Starship SN3 cryo pressure test didn’t go well (w/vid)

My analogy (vacuum crush) was wrong.
Here’s a decent explanation
It was clearly column failure due to heavy NH4 tank (above) being too heavy for the LOX tank (below) which was insufficiently pressurized to provide rigidity.
(See: crushing a beer can on your forehead)

I’ll bet on procedure error (oops! wrong valve) or fitting failure (leak)
Rapid-prototyping gets us back to the good-ol’ days of rocket development (’63 Atlas depressurization collapse vid and story)

    Elon Musk may have some issues, but, thinking big isn’t one of them.
