Welcome to Newmars Sinn
This appears to be a Pica panelled side of the ship.

Thank you!
To me it's just the same structure with bare SS sheets with contre-jour effect smile

The stainless steel vehicle under construction is not a prototype BFS,  despite all the sincere beliefs and wishes otherwise.

Fully agree! The thing is more like a mockup for me.

Stainless steel exposed to re-entry aeroheating would only survive with massive amounts of liquid cooling.

Massive amounts but not with "residual liquid methane"? The residual amount is smth like 10t or more?

Everything is covered in PICA-X,  to a max steel temperature of 1000 F.  Black-surfaced on the windward side for higher re-radiation,  white-surfaced elsewhere.

Hello there!
But Elon eliminated of PICA-X heat-shielding recently.
Or I just misunderstand the twit - "windward side will be activity cooled with residual (cryo) liquid methane, so will appear liquid silver even on hot side"?
