I think that’s the normal shutdown order to reduce shock, the timing was exactly the expected second stage shutoff time if I understood it correctly.
Incorrect it failed asymmetricaly in such a way that would pitch the vehicle in circles. Normally the sea level raptors are turned off and the space raptors are slowly brought down together.
One of the three sea level engines went out and stayed out. It didn’t look normal. The numbers stopped updating with one engine still on.
Right, I just watched it again and it didn’t look normal.
But interesting that telemetry showed the failures starting a few seconds before loss of telemetry, the videos posted here show a massive explosion later on. So something was going wrong for some time before, and the explosion was only a consequence of that.
Or it was the FTS reacting to the engine failures.
