Looks like the ship lost roll control. It was re-entering pretty side on instead of belly first. Tim Dodd thought the hot gas thrusters may have gotten clogged with ice.

Thanks to everyone posting in here, couldn't watch the webcast so it was good to catch up on everything that happened!
well, that was pretty good. i wonder why the booster reentry was oscilating so much, and the ship reentry didnt seem very controlled either. incredible video from the ship during reentry though.
So I guess still no orbital flight for test 4? I imagine relighting an engine in space was a requirement.
Yeah, that would seem prudent. Wouldn't want a Starship stuck in orbit and then reentering uncontrollably, a la Long March 5B.
Still no signal from the ship. Reentry started a little bit early, so I would think it would be transonic by now.
Edit: Loss of S28 confirmed on the webcast. Now we just wait for Scott Manley and Zack Golden to tell us what happened :) See you all for IFT-4!
Views of re-entry! Look at that plasma!
Hosted webcast is back. Payload door opening and propellant transfer were tested, still awaiting data review. Raptor relight imminent.
Edit: It sounds like Starship decided to skip the raptor relight. Going straight to reentry.
As much as I'd like for those rotations to be intentional, for now I'm assuming they didn't relight because they lost orientational control.
I can't watch any videos right now, how is it going?
Starship is descending into the atmosphere
Wings have just folded at 110km altitude
They just announced that the PEZ door is opening.
Starship is supposed to coast for the next 30 minutes, until T+ 40
Any news on the propellant transfer demo?
they announced it completed. Not sure if it worked as intended.
SECO and nominal orbit insertion for Starship!
Booster survived the boostback burn this time!
Edit: Looks like there was an issue with re-entry and landing burn, but the booster made it further than last time!
Hot Staging!
45 seconds in, amazing all engines look great
Onboard views from the booster and ship this time!
Liftoff!
Prop load closed out. Winds are looking good.
That fog cleared fast!
It is looking like it might go on first attempt!
Everyday astronaut stream has a thermal camera showing fueling
SpaceX are live. Kate Tice and Siva Bharadvaj are hosting.
Prop load has started on ship and booster:
https://twitter.com/SpaceX/status/1768254337204260905
Propellant load of Starship’s upper stage is now underway
https://twitter.com/SpaceX/status/1768255938526626089
Prop load of the Super Heavy booster is underway
Prop load soon!
https://twitter.com/SpaceX/status/1768251797846847981
The Starship team is go for prop load but keeping an eye on winds, now targeting 8:25 a.m. CT for liftoff
Wayward boats again...
https://twitter.com/SpaceX/status/1768243304054092192
New liftoff time is 8:02 a.m. CT, team is clearing a few boats from the keep out area in the Gulf of Mexico
On the bright side, it's now scheduled for after sunrise, and the fog seems to be clearing!
Edit: https://twitter.com/SpaceX/status/1768246454328742222
Shifting T-0 a few more minutes to give boats time to clear the keep out area, now targeting 8:10 a.m. CT
Dang boats, always disappoint. Hopefully it's for the best!

I think this is the correct link for the SpaceX official feed on X/Twitter: https://twitter.com/i/broadcasts/1LyxBnOvzvOxN
Looks like it's scheduled to start at 6:56 CDT now that launch is targeting 7:30 AM CDT.
Thanks! Added to the main post.
Launch time has been pushed 30 min (7:30 local). The window is 110 minutes.
T-0 pushed by 30 minutes: https://twitter.com/SpaceX/status/1768231845551096149
Weather is 70% favorable for today’s third integrated flight test of Starship.
The live webcast will begin ~30 minutes before liftoff, which is currently targeted for 7:30 a.m. CT → https://www.spacex.com/launches/mission/?missionId=starship-flight-3
Looks like some sort of fuelling is underway. Or at least chilling lines in the OLM and tower in preparation for filling.
