Titanic tourist sub goes missing sparking search

[Gone for diving]

In fact that is one of the concerns as there is no mechanical release for the ballast just an electronic one that relies on wireless communication between the controls inside the hull to a control box mounting on the outside.

Don't know if its true.
But some people say it has dissolving bolts that release over time....

If the hull is breached it will not help.

If the hull is intact. And not tangled or trapped.
It should help.

What is amazing to me is that it doesn't at the very least have one stand alone multi directional pinger
That goes off after a certain amount of time.

We even have the technology
To send out a certain frequency and active a function to release stuff from underwater like a bouy or in this case, weight or a float of some kind. Or even turn on a super strong pinger.

Some articles talk like nothing goes through the outside walls of the people chamber, but this video describes a hydraulic operated pump that drops weights. Also a 10k psi tank that fills a lift bag.

This is a pretty good video, I'm going to check out his others.

I’ve piloted a lot of boats walking ROVs. The pinger is always on, always self reliant, containing it’s own batteries.

I’ve tracked and recovered a lot of very expensive practice torpedoes. Way more expensive than the real thing. The pinger activates at the end of the run, and pings for about 24 hours. Not as robust as an ROV pinger, but if you don’t get it in 24 hours, you’re probably not going to.

This is not experimental technology, and I don’t know enough about OceanGate to know why this sub didn’t have one, or if it did, but if not, that’s criminal IMO.

Yep not having one would be shear stupidity, (not to mention self preservation)and you should not be building a sub, or maybe hire a few white old guys,

Trying to find a minivan, 12000ft away, in the dark, over a range of a small town.. with no active pinger....

The titanic was has hard enough to find, and they where looking for a huge debris field. Not the actual wreck

Probably going to have to wait for a Youtube video after the fact going over the engineering, probably after any lawsuits are settled that goes over it in detail.

I really don't think that "one button" concept was a very good idea. Can you imagine even an airplane with just one button?

I am really, really hoping for a miracle because at this point, it would have to be a miracle they survived.

I am one of the crudest people I know, but damn, can't we at least wait until we know they are dead before we make fun of the situation? Some of the comments on this thread are embarrassing, at least I have a few more entries into the ignore roster.

The $250,000 question is when will it be appropriate. @johndiver999

Ya, a single point of failure for everything electrical doesn't seem very smart...

One of the guys on the sub is a former navy person who was on a big sub. He know what the procedure is to signal from depth for them to be found. It is apparently to bang on the hull for 3 minutes on the hour and 1/2 hour. I believe there are two ships on site that have ROV's that can go to that depth and beyond. They have sonar capabilities, lights and a mechanical arm. If they are on the sea bed and someone is still alive and banging on the titanium then this shouldn't take much longer to locate the sub. But they would still need to send down a cable - connect it to the sub and raise it. Let's hope that happens today.
