I've seen stories of people tracking stolen vehicles or phones on their own.

Always thought it was a bad idea,

Woman shot, killed after tracking stolen vehicle with Apple AirTag

Yikes. My AirTag is being used for a similar purpose, but not with a vehicle. Although, in honestly, that's not a bad idea for general tracking. Just don't go after it after it's been stolen.

The sub imploded.

Coast Guard to give update following 'debris field' discovery

When a sub crushes, this comes from reports on the Thresher and Scorpion and post war crush testing.

At that depth, the failure takes milliseconds, the water explodes in, death is instantaneous from traumatic crushing. The compression ignites the air. Thenthe water hammer blows the pressure hull apart. The hull is designed for external pressure.

I haven't seen any description about whether the sub was autonomous or tethered to its surface vessel. Do you know? Given that I never saw any indication about them attempting to pull it back up, it sounds like it was autonomous, which seems unsound given the lives aboard (and the freakishly unsafe building practices you have described before.)

It was not tethered, but operated remotely from the mother ship as I understand it.

Autonomous as far as I know no tether. To control remotely it would have to have at least with communication cable.

They used a game controller in the sub.

Right, I saw your message about the game controller. And more news is coming out about how the owner of the company did NOT want to have the proper safety tests done and fired the guy who wanted them. 

I'm expecting this situation to become the standard safety story in engineering programs starting in the fall.

All the submersibles I've read about have robust safety measure. At least a 50% safety margin on dive depth. Redundant safety systems. This one what I've seen in the last few days looks very sketchy.

It had several safety systems to surface, but some who went on it said it had other problems. A Discovery network producer went on a test dive and decided not to go to the Titanic as he felt it did not handle well. Some others had similar concerns.

And then there is the engineer who refused to certify the sub for carrying passengers because the materials were not tested - and was fired. I think he can feel better that he didn't certify it, but he probably feels bad that he didn't do more to prevent the sub from being used.

I had guessed this was the case:

Navy Believed It Heard Titanic Sub Implosion Hours After It Started Dive, Reports Say

Something about the US response told me we knew the sub was lost.

The “anomaly consistent with an implosion or explosion” was heard by a secret military acoustic detection system the Navy uses to track down enemy submarines, according to officials interviewed by the Wall Street Journal.

The sound was picked up just hours after the submersible began its dive Sunday and came from a location within the vicinity of where the submersible was when communications went down between the sub and a vessel on the surface.

Neo-Nazis prefer Biden

“I would say a lot of what the world knows about white supremacists nowadays is smoke and mirrors. They’re far more pro-Biden than pro-Trump – Trump was too pro-Israel,” John Daly told the UK’s Jewish News outlet.

In a discussion about current white nationalism and antisemitism in the U.S., Daly mentions the disparity between media portrayals and his understanding of white supremacist groups, which are more than not from the progressive end of the political spectrum.

“There’s a stream of Nazis called ‘The Accelerationists’ who just want to see the world burn,” he told the Jewish News.

“They’re like ‘”We’re gonna take what’s already bad in society, amplify it to the point that there’s enough riots going on that hopefully other white people will say ‘this is bad, the only way to get safety is to join the Nazis’. That’s a very powerful group in America right now.”
