The incident highlights significant operational failures, as engine shutdowns should not cause communication loss, indicating a lack of redundancy in systems."

For the communication redundancy part: This is just my interpretation of what I'm reading and it could be 100% wrong.

The communications need a redundant power supply/ connection not associated with the engine. Because they didn't have the communication connection and the engines were on fire the self destruct was initiated. Where if they had communications maybe they could have done something else? Turn off fuel, changed location of impact, changed location of self destruct to not be where it was.

I could be wrong, Iam in fact not a rocket scientist

That’s also my interpretation. Which tracks with Musk companies, which tend to cut corners by cutting out redundancies.

At least with the Teslas, they also fail to isolate systems for cost cutting, and everything tied into the same bus causes a weird cascade with completely unrelated components when there are failures. If he’s forcing the same design philosophy with the rockets, that’s a completely moronic move.

Also, I don't think the engines provide electrical power, that'd be from the batteries.

Edit: yeah, they use helium to spin the turbo pumps, so no electrical generator/motor on raptor.

Two engines exploded, blowing the back of the ship up, causing the ship to tumble, which lead to loss of communication a few minutes later. Abort was absolutely the right call. Saying communications need to be better is like saying you need a better bandaid for your stump of an arm after you blew it off with a grenade.

The communications failed because the ship was spinning faster and faster, and eventually the antenna tracking couldn't keep up.

As soon as the engines exploded, the mission was dead, so the best thing is to abort, which is what they did.
