Relight did not occur. It is unclear at this point whether that was a computer decision or a failure of the engines to relight.
The roll (not explained) caused the computer to not relight the engines. It was not an engine failure but the roll itself is not explained. It burned up during re-entry.
The booster not relighting properly seems to have it exploding at 460+ meters in altitude (not a flight termination as the explosives had been "safed").
Funny watching the naysayers ignore that their predicted failures didn't occur and target the goals not accomplished instead and predicting that this is the best that could happen in the future (just like they did after the 1st two flights).
IFT4 now showing as April 2024 (no day of the month). Lets see if the FAA will issue another license that quick.
