Ship 37 fires up in what should be the final SF ahead of Flight 10.
They will need to dismantle the mods to Pad 1 to allow the static fire before they can then full-stack B16 and S37 for launch.

Multi angle replay of Starship S37's 6 engine ~10 second static fire test on the Pad 1 OLM from @NASASpaceflight camera angles.
Based on past tests, we expect S37 to next be removed and returned to MB2, while the Pad is prepared for flight configuration.
