Starship's Tenth Flight Test

Some kind of failure in the lower engine area.

Figure it's going to burn up on entry?

EDIT: made it. I suppose it was meant to blow up on landing in the ocean? It would have been nice to examine the burned components — but perhaps they had not intended to retrieve it that far away anyway.

The walls are 3mm thick steel, they're very likely to buckle and tear when it tips over, the residual methane vapor gets out and there are plenty of sources of heat to ignite it.

They don't claim to have any plans of recovering the wreckage, but they have previously fished up wreckage for study, so it's still possible they decide to do that.
