The red and orange flames coming from the rocket was indicative of more engines failing as time went by.  As failures go, it was very impressive.  It was quite amazing just how long the rocket structure held together while it was corkscrewing.  That was one strong rocket.

The SpaceX feed was mentioning as it went up that everything after they cleared the tower was a bonus for them.  Looks like they had control even with engines out until they started the flip for stage separation.  It over rotated and they couldn't get it to stop flipping after that, so they couldn't get Starship off the booster.

They gave it a couple flips then RUD.

Super cool though. Largest rocket ever to lift off, and they said at the beginning it had 10,000,000 lbs of propellant on board.

Yeah, it looked like it was running engine rich exhaust from the beginning.

Amazing launch regardless.

Was thinking the same thing. Says volumes how strong they built that thing.

Eventually, SpaceX will work the bugs out and Starship and its boosters will be as reliable as the Falcon 9.  That will be ultimately very cool.

Elon had already said this was an obsolete vehicle with all the changes they've already made.

IIRC, he estimated a 50/50 chance this would be a successful flight with Starship reaching splashdown.

Wonder if there was an issue with the clamps between SS and the  booster not releasing?

The way the whole thing was corkscrewing, maybe it jammed the release mechanism.

I sort of kind of get the impression from a SX tweet (which I can't find now) that they did attempted the flip to start release and maybe that started the corkscrewing. I could have misread the tweet in the excitement of the moment. Corkscrewing could have started before. Will have to go back and read/hear more but it's time for food.

NSF just said it appeared to them one of the HPUs (Hydraulic Power Units) exploded at T+30.
The HPU control the gimbling of the engines.
Some speculation they may also power he release hooks.

IIRC Elon already ditched HPUs in B9 for electric motor gimbling.

This don't look good
It WAS solid concrete under and around the OLM. Now blasted dirt and a crater.

Nope, just pretty much a flat concrete surface.

Yep, not even a deluge system.  They have one that they haven't installed yet, and I'm sure it will be integrated into repairs.  But Musk was really curious if the rocket could work without one at all.  Fixatedly curious on the issue.  Probably because taking off from Mars or the Moon will require launch from an unprepared surface.  While those are Starship-only, evidently they prioritized the test data for SuperHeavy highly enough to risk this type of damage to the launch mount.

NSF was saying their parked camera van got hit.
Someone caught it on camera
