I wonder if the hot separation was supposed to be that hot. Going at mach 5 and doing a quick U turn while there was some weird orange color on the side of the Super Heavy, then (possibly?) losing most engines from it seemed extra chaotic

They had a similar issue with the v2 booster the first time, flipped it so hard it damaged the downcomer and they had to change it up a bit. Seems likely here, that thing thats as big as a building flipped ends pretty quick and is partially filled with liquid.
