Sounds like a proper test. But annoying that Musk's name has to be plastered over every headline related to Xitter, Tesla Motors, Starlink and SpaceX.

So the booster worked in that it achieved lift off and properly separated. Did the other stages complete their jobs? Because this looking like it's only a failure in the sense that the booster didn't do the cool we-live-in-the-future part of flipping itself over and landing.
The main focus of this test was stage separation. In that sense it was a roaring success. Also, looks like they managed not to trash the landing pad this time. So that will make it easier to get the next flight approved. But clearly there's still a long way to go.
Also demonstrated the flight termination systems, for both stages, it seems.
It appears they got their engine development under control too. Every one lit and burned effectively full duration, on both stages.
So basically they've fixed every issue displayed in the first flight I'd say.

It seems that Starship, the second stage, experienced RUD from the automated FTS at around the time it was expected to shut off its engines.
Edit: RUD is Rapid Unscheduled Disassembly. Basically an explosion. FTS is Flight Termination System, which explodes a rocket if something goes wrong in a potentially dangerous way.
Which is an incremental improvement over the prior attempt. People mock these failures as though they have never built anything and have no concept that any step forward is a win when you are trying to do something that has never been done before. They got the smaller rockets working. It will just take time to get this giant one working.
Yeah but to get from here to a 99.99% reliability is a very very long way
Look at the Falcon rocket history. They started out at a very similar point, though at a smaller scale. And yet now they are comfortably human rated. They have landed the last 171 times in a row without fail, with another one coming this evening to add to that incredible number.
The guy at the helm is a terrible person, but this does not discredit the absolutely insane progress they have made.

RUD, aka “Rapid Unscheduled Disassembly”. I love how you can make “shit blew up in a way we didn’t expect” sound so mundane.
Well done to Musk and team for what most people would deem a huge success. Great to see. Really fun to watch and follow space x huge successes over the years.
Sorry it goes against the narrative and people can't enjoy how great this is.
I'm frankly impressed they got 30 methane burning rocket engines to run flawlessly like that. mind boggling how quickly it leapt off the stand. fuck musk 8 ways from sunday, but I dig spaceX, shotwell has figured out how to manage musk's bullshit apparently and is doing great work.
The 33 engines burning all together was really impressive to watch. The burn looked so clean and compared to the previous launch where engines where just failing on after another is was nice to see the huge progress.

It is quite the accomplishment to get to the Karman Line though so credit to SpaceX's engineers.
On the one hand I want to enjoy Musk failing, but at the same time I want to praise the people who are putting all their time and effort into the project, so this comment speaks to me.

Here's a pre-launch article in case anyone wants to compare pre-launch expectations to reality.
Four out of five ain't bad
While this test was much more successful than the last one, it shows it will be at least a couple years before starship is fully operational at this rate if development and who knows when they'll be able to get it crew rated.
So I'm already willing to bet artemis 3 gets delayed by at least a year while starship gets developed, which is a big shame.

Gotta love that "Starship breaks the sound barrier during launch" image with the shockwaves visible. NO that is not what happens because the sound barrier was broken, the rocket was already going trans- or supersonic and the resultant shockwaves became visible briefly due to atmospheric conditions. Shockwaves do not spontaneously become visible at the point of transition.
Nonetheless we're going to see that image pasted over and over on social media stating that it's the transitional indication of breaking the sound barrier.
This is the best summary I could come up with:
SpaceX’s gargantuan deep-space rocket system, Starship, safely lifted off Saturday morning, but ended prematurely with an explosion and a loss of signal.
About two and a half minutes after roaring to life and vaulting off the launchpad, the Super Heavy booster expended most of its fuel, and the Starship spacecraft fired its own engines and broke away.
“The automated flight termination system on second stage appears to have triggered very late in the burn as we were headed down rage out over the Gulf of Mexico,” aerospace engineer John Insprucker said.
NASA is investing up to $4 billion in the rocket system with the goal of using the Starship capsule to ferry astronauts to the lunar surface for its Artemis III mission, currently slated to take off as soon as 2025.
The endeavor is aiming to return humans to the moon for the first time in five decades, and the successful completion of this test flight would bring the US space agency and SpaceX one step closer to that goal.
During that test flight, several of the Super Heavy’s engines unexpectedly powered off and the rocket began spiraling out of control just minutes after liftoff.
