It blew up.

Other engineering translations:
Percussive maintenance = I hit it and it started working
Cycle power to the panel = Turn it off and on again
High impedance air-gap = I forgot to plug it in
Organic grounding = I got electrocuted

Ha!!! I love it .

Kinetic disassembly hehe nice
 
Looked to me like one engine flamed out at ~T+1:40...

I don't think it ever came back and that's what doomed the landing. Not enough thrust from only 2 engines.

Probably accurate to call it a success (or a successful failure, aka Apollo 13). It blew up on landing, but the data stream will allow them to avoid it next time. And it worked on 2 of the 3 tasks.

I think they actually shutoff the engines intentionally. There was some gimbling of the engines right before the one engine shutoff around T+01:40, the second engine shutoff around T+03:13, with the final engine shutting off at T+04:41 just as they rolled over to horizontal glide.

At T+06:31 the first engine restarted, with engines two and three both restarting at T+06:32. As the ship rotated back to vertical, the engine exhaust took on a green tint around T+06:38. It's hard to see, but it looks like engine two flamed out at T+06:39. At T+06:40, it is a strong green and black smoke is present in the exhaust and I cannot tell if the other engine is still running.
 
Elon Musk tweeted "fuel header tank pressure was low during landing burn, causing touchdown velocity to be high & RUD*, but we got all the data we needed."

It might be a good idea to put the nose mount descent engines for the Lunar Starship if not Buran Analog turbojets on the winged articles to preserve the airframes for even rougher tests

SpaceX has officially jumped the shark. Er, I mean, the tower arm has jumped the giant explosive firemaker.

yeah I can't see this working to well as describe with a very potential for RUD.

I'm not sure how stable the Falcon 9 heavies are without legsl but a bet approach might be to land the rocket and quick swing the tower back in place which gives you a bit of lee way but are they okay to sit on the engine nozzles (or is there an assembly in place - look at some images but can't quite tell).

Do you have to do hyperlink diarrhea over every single goddamned thread? does it just bottle up inside?
