The funny thing is that this forum is actually filled with people who have more than a passing acquaintance with those subjects. I know you were being smarmy but that is just a fact.

My question is not about the lengthy waiver which I am sure is "detailed". Will an investigation into this for profit company show that they knew of problems and issues with the operation but failed to pass those details onto the "tourist"?

It is one thing to tell people you are undertaking a dangerous activity. It is quite another to have operational issues and maintenance issues and quietly keep that information to yourself as you cash their quarter of a million dollar check.

You mispelled "Windstar". Or your shelf designations are incomplete. Razz

more ominous news

The Titan pings (underwater sound) every 15 minutes to the support surface ship (Polar Prince)

This allows the surface ship to estimate the Titan position and depth

Although the reporting gets messy, it sounds like the support ship lost text communications with Titan at 545am local on Sunday. But the 15 minute pings kept happening.

The pings stopped being received by the surface ship about midday yesterday (Monday). The location showed Titan directly above Titanic.

Seems another very bad indicator that the pings stopped

This is a quote from some of the reports:

"Just one hour and 45 minutes into the expedition the submarine lost contact with its transport vessel - the Polar Prince, according to the US Coast Guard.

The company previously revealed it uses Elon Musk's Starlink to communicate with the vessel, however it's not clear what has gone wrong with the network."

Speculation on my part:

Starlink communication is to the Polar Prince, not to Titan.

Polar Prince communicates to Titan via USBL (ultra-short baseline) acoustic system.

They don’t use submarine type ballast tanks that they can blow out with air pressure on things that go this deep. They use ballast weights that they drop when they want to surface.


That’s even better. There’s no reason not to use what they were using then.


What were they using?

Yeah , I'd love to see their resumes .How many of them do you think actually built or operated deep diving submersibles ?

Basically heavy debris. Instead of venting air and water to maintain whatever buoyancy they want they drop "construction debris" is how they described it to gain buoyancy.

George, I don't understand the Windstar reference, please explain. The RC cruise dining experience was as good as almost every restaurant I have ever eaten in. Outstanding top shelf (there is the shelf reference again) cuisine. The bars had fantastic drink options, from old fashioneds to martinis, something for every taste.

Don't be a dick. Many of us have a pretty good working knowledge of submersibles. I personally could pick up the phone and speak to everything up to a 2 star submarine admiral and get as good an understanding of the subject as you could ask for. Many on this forum are the kind of guys I would call. Yea, they are experts on the subject.

Nobody has any first hand experience on this particular submersible because it is basically a one off design. That is quite different from nobody knows dick about this subject.

Fucking asking for resumes. Oh brother. Which part of this discussion do you think is off base on the technical side?

So, it sounds like they lost text communications 1 hour and 45 minutes into the dive, but the sub kept pinging for another day and a half? You’d think they would have dropped ballast soon after they lost communications, if they could have. Wonder what the tracking showed between the time they lost text until the pinging stopped. Reaching the bottom, and then stationary?

It sounds like the pressure hull or portal gave way and probably imploded. The pinger was probably outside of the pressure hull, and it kept going until it failed somehow.

I wonder if anyone that studied metallurgy was involved in the construction of this sub.

Seriously ?

Looks like a Coast Guard press conference is coming up.

There is a quote from the CEO on twitter “I think I can do this just as safely by breaking the rules”. He was talking about the balance between risk and reward. It’s twitter so I can’t say it is his quote but if it is, it seems a tad cavalier considering the razors edge margins his company deals with.

Then I apologize. Your comment read as sarcastic and apparently you didn’t mean it that way. My bad.

Our society- driven by the sensationalist, bloodthirsty news media- has its priorities upside down.

What are we talking about? The lives of six or seven people? But this is headline news and we're waiting for press conferences and a US congressman wants to send a multi-billion dollar nuclear submarine on a wild goose chase.
It's morbid. These people are almost assuredly dead. People are waiting to hear the worst, some of them hoping to hear the worst.

I'm not saying we can't discuss it here, but just take a look at the muckrakers licking their chops.

Yeah, this is the place I keep coming back to. It's not a group of people trying to go to the bottom of the Marianas Trench. They're not visiting an ocean floor volcano. Graveyard is even too kind, there's debris from long-eaten and dissolved corpses scattered for thousands of yards. Then there's the ship itself. The intent is purely to gawk.

Not yet mentioned is that the wreck is dissolving, which creates the sense of urgency that's the core of all good sales pitches. Also not mentioned in any of these articles I'm looking at is some supposition I read somewhere a few years ago claiming that it was most likely James Ballard's expeditions to the Titanic that introduced Halomonas titanicae to the wreck because this kind of degradation wasn't seen on it in the first pictures. They're giving a sales pitch that appeals to the hubris of the super wealthy to go look at a wreck of a ship that sank because of the hubris of the super wealthy, which is dissolving because the hubris of the super wealthy compelled them to go find it - By my count, nature wins two times out of three and it's only two for three so far because we haven't found this thing crushed at the bottom yet.

I also don't understand the risk/reward calculation considering the recent new imaging of Titanic. "a three hour tour, a three hour tour..."

Isn't that the norm for these kinds of stories, especially when we add in something like the Titanic, some billionaires, and the fact that people (presumably) died in a sea going accident while going down to look at a ship where people died in a sea going accident.

Wonder who's going to play the lead in the made for TV series...

They probably will find its debris scattered around Titanic, almost if the old girl is asking them to leave her and her dead alone....

It also was a mediocre cruise. Meh service, meh food, meh just about everything. A month later we did a Royal Caribbean cruise. Everything from, food, entertainment, cocktails was top friggin shelf. Outstanding.

Not really a fair comparison, Carnival is the WalMart of cruise lines, a mass-market, value operation; RC is more of a mid-tier, Nordstrom-level operation.

Lead weights to gain buoyancy. Challenger Deep and various other deep ocean spots is littered with such.

Looks like a pipe laying vessel, Deep Energy, has arrived on the scene. Article says the company has subs capable of reaching 4000 meters, which is enough to get to the bottom. Unfortunately, it says the ones onboard only go to 3000 meters.
