I watched the whole thing live (to my regret) and when things started to go wrong I thought the gimbal signal and speed indicator were just not reading out, or the data weren't being received. The one consistent thing was the loss of altitude. Apart from a couple of obvious spurious readings, the loss of height was very consistent yet ignored by the narrators/commentators on the live stream. And even when the altitude bottomed out at around 240,000 ft, they kept on going on about what was going to happen next.
I was 99% certain the next event was the thing breaking up on re-entry and whatever remained and didn't burn up could be found at the bottom of the Atlantic. And I'm not a rocket scientist.
