Doesn't our Navy have an underwater cable all over the Atlantic that was laid during the Cold War to listen for Soviet Nuke subs? I think I read that in a Tom Clancy novel or something.

I wonder if it can pick up acoustics in the search area.


That is true. If you're interested in subs through the cold war, Blind Man's Bluff is an awesome non-fiction book.


I'll second this recommendation. However, to possibly answer your question Blind Man's Bluff tells a few stories about searches for missing subs, and one of the challenges has to do with identifying the right noise. I imagine a carbon fiber hull failing wouldn't even get past the filters, and I doubt anyone really knows what it would sound like.

Has it been discussed how many times this thing actually made a successful voyage down to the wreck? I've read expeditions are 5 days and they might only make it down once or twice...or zero. And it apparently was not uncommon for it to get lost for hours at a time.

Has it successfully made it down 5 times? 10? 20?


It's not made it once. This was the first try. The previous "test" only went down to 3000m with only the CEO. So they have never tested the hull integrity beyond 3000m and the Titanic wreck is beyond that.
Wouldn't it make sense to send it, unmanned, to deeper depths than the lowest manned depth it would ever need to handle?
It's been all the way down to Titanic a few times, plus several other unsuccessful attempts. In fact, that's the concern, the repeated strain on the hull. I don't know why anyone would say it's the first try for this particular craft.

The Titan has visited the Titanic wreck site three times, the first of which was in July 2021
It would be nice to have a proven safety margin. I don't think that having gone to the same depth twice before tells you much at all about the safety margin.

Not only on hull depth, but also to make sure that the electronics are highly dependable and aren't defeated by getting damp or wet.

As for not being able to open the hatch from the inside, that reminds me of the Apollo 1 fire. I remember Aaron Cohen telling about how hard it was to make changes to the capsule hatch to allow it to be opened from the inside, but it was clear that it absolutely had to be done.
I'm not commenting one way or the other about what they should or should not have done, I was just correcting the idea that this was its first try. Reading more about it now it actually seems like it's made a whole bunch of successful trips to the Titanic, but evidently three (not sure whether that includes this one or not) trips with tourists.

From today:

How many times has OceanGate been to the Titanic?

OceanGate has taken tourists to the Titanic in the Titan submersible three times in total, once each year from 2021 to 2023.


How many times has OceanGate been to the Titanic? (hitc.com)


From March of 2022:

The OceanGate team completed several successful dives to survey the Titanic aboard Titan, the world's only five-person submersible to reach a depth of 13,000 feet, over the six weeks after our first expedition. The team of renowned experts, researchers, and citizen scientists collected the highest-quality photographs and wreck footage to date, including parts of the wreck never photographed before. OceanGate's Titanic footage is available at youtu.be/oDLzG1W0Cik.

By the end of 2021, the team


By the end of 2021, the team had accomplished 10 successful dives to the Titanic: four at depth along the debris field and six surveys of the wreck. Titan's large viewport allowed three people to simultaneously view and document the Titanic as the pilot and copilot attended to the controls.

I don't think it's a fair comparison to compare controlling an underwater sub to aiming something.

An underwater sub like the Alvin has multiple motors that can be vectored in an assortment of ways. Moving underwater is more akin to moving in space than air. The pilot of the Alvin can very precisely control what the sub is doing and it seems more complicated than what can be fit on a single game controller. There's a video i linked yesterday that shows their cockpit.

Maybe some simple motions are done with that Titan controller buts it's hard for me to imagine they have the same level of precision as Alvin.

Here's an interesting thought experiment: At this point knowing what we know in terms of estimated time remaining before all the oxygen is consumed, do you dedicate resources to focusing on the surface of the ocean in the event that the sub has miraculously surfaced and just not been spotted, or do you continue to focus under the ocean knowing full well that you won't reach them in time?

For me, I think focusing on the surface would be the priority as if they are there, there is a chance that they can still be saved. If they are below at the bottom of the ocean, there is no realistic scenario at this point in time that saves them.

If they're banging on the hull why aren't they banging a specific pattern/rhythm that would make it impossible to be an underwater anomaly. Tap out SOS in Morse Code or "shave and a haircut".

I've worked around incredibly successful narcissists most my career. I'm pretty familiar with these types of egos.

That said, I knew there would be at least one person taking issue with that comment. Two things can be true at the same time. The adults that signed off are responsible. But none of this happens if the CEO doesn't put on a song and dance about how cool and innovative his approach is. They're all culpable, but he's the primary asshat here. That's all I was trying to say.

Eta: this guy actually reminds me of a financial scam artist. As investors or even gambling degenerates, we all know the risks with any investment. We know we are responsible. But the Bernie Madoffs of the world can still be the main culprits in these fiascos.

Unless they are stuck in the wreckage itself or stuck at the ocean floor almost directly adjacent to the wreckage, I doubt they will ever be found. And this is a boat that would regularly get lost for hours at a time.

I'm surprised their marine insurers didn't mandate classification as a condition of cover especially when they were carrying passengers.

He honestly seems like a conman. I can never tell if these types believe their own bull**** . I guess they were warned in the waiver death was a possibility, but the CEO clearly drove unsafe engineering practices.

Even if they did, I'd wager the underwriter denies any claims related to this incident. Seems there's enough gross negligence to void the policy, to me at least.

A number of people have reached the bottom of Challenger Deep, in the Mariana Trench, just under 36,000 feet deep. The first was in 1960. James Cameron has done it solo and Austin-based computer game designer Richard Garriott has been to space and also to the bottom of Challenger Deep. The Titanic is only a third as deep.

Those are terrible. Knowing your subs going down and not a damn thing you can do and just waiting for the boat to implode. At least (from what I hear) it's over before your brain can even process why last happening

This was a neat if not interesting take on the Thresher. Interesting theory and a bit conspiracy theory.

Here's more clarity from that CBS reporter that did the feature last year.

Watch from 1:30 to 1:50. He says at the time he got on last year he wasn't worried because it had been to Titanic successfully not 3 times as people have said but 20 times and it's been down even more times since then.

Probably has had more testing and real-life abuse than anything the military could design.


#truth

I would think on an experimental machine you would want simple backups for things like the controller. For instance, is the ballast release mechanical and operable with no power? Or does it rely on a circuit that becomes inoperable due to power failure.

Complete power failure would mean no modem for comms and potential no ability to resurface. Nothing I have seen yet shows what redundancy they had or did not have in place.
The problem with that is that it requires a through hill connection to make it accessible from inside, and every through hull penetration is another point of potential weakness. I would rather see a ballast release that is held closed as long as the communications circuits are active, but automatically opens if the circuit connection is lost for longer than xx minutes.

Magnets are your friend here. Particularly with carbon fiber you could either avoid the through hull connection... or you could have the ballast secured by electrified magnets that dropped in total power loss.

I guess it would be best if the craft just imploded making it a swift death then slowly suffocating. Unless they are found.
