The son definitely didn't want to go. He was very afraid of the trip, just did it to make his dad happy.

Off topic, but for the marine biologists out there.. how does sea life even exist at those depths? The same depths that can crush big thick metal submarines like tin cans also is home to crustaceans, fish, jellyfish, and coral. How is this possible?
Just think about the name recognition on their resumes.Mathguy64 said:

Because that's the habitat they were born in. Species naturally survive in different conditions.
Those species that dwell at the bottom can't live on land. And we can't survive under water much less in those depths. Our cell structure is made for the environment we live in.
Edit: also read some where that cephalopods have no air in their bodies and are deep sea creatures. No air, no problem. And more jelly like.

They should attach pictures of their work. Like screwing a monitor directly into the carbon fiber pressure hull. Im sure there is no chance that could ever have created a small stress riser. Yeah. None at all.
I read somewhere that 80% of ocean remains unexplored, untouched.
I find that realistic and amazing. Probably why these guys get hooked on these dives.

Like any other life forms on earth, they've adapted to their environment.Quote:
Really, REALLY deep-sea fish undergo a really cool and horrific process when they come to the surface.
Their cell membranes melt.
If you remember from high school biology, all animals have cell membranes made from fats surrounding their cells. Most animals actually use similar or identical fats in these membranes because the conditions the membranes need to survive are basically the same. This is not the case for deep-sea fish. If these fish used the same fats that we do, their cell membranes would be the consistency of butter at their home depths, and thus be completely useless. Therefore, they use a different fat. However, this fat can't hold together under pressures less than those in the crushing depths, and they liquefy. Therefore, it is actually impossible for us to capture live specimens of these fish.
TL;DR: The fish melt because science likes them where they live and not where we live.

And all of the massive fish/shark/whatevers that stay living down there.
Curiosity killed the cat and Mother Nature always win. We are mere inhabitants of earth. You have to respect the boundaries.

Also, wonder what he's doing in Austin.
Staying weird.
agracer said:Based on interview's with the CEO I've seen, I'll bet he got multiple alarms on the way down and just ignored them until it was too late.bonfarr said:
The Titan had sensors that did some type of scan of the hull that supposedly could warn them when there was a danger of a hull crack. I assume they got an alarm then they signaled the mother ship. The CEOs plan was to ascend as soon as they got an alarm showing they were in danger but we see how that went.
The acoustic sensors and the patent are bull***** You can patent anything, a patent doesn't mean it actually works. This guy was just arrogant and never actually did the R&D necessary to show you could detect defects prior to failure in real time.
You can detect defects with acoustic tools (think ultrasound), but by the time you can detect it, it's already damaged, and I doubt most of these tools would be useful on carbon fiber that is 5 inches thick. This is not something that makes any sense to do in real time under load outside of R&D testing because by the time you detect the defect it means the structure is already compromised, and if it's under load it will be too late.
I have some experience testing carbon fiber to failure (ultimate tensile strength and bending cycles). It can be quite impressive in many applications, but it's not suitable for everything.

They could have screwed into an internal superficial shell. I haven't seen proof that the interior wall is actually structural. I have seen the image that clearly shows they screwed the monitor mounts into the interior wall, but I have to assume that wall wasn't structural, but a superficial interior layer.
If they screwed into the structural carbon fiber then their ignorance is beyond my comprehension. It really was clueless young engineers led by a deranged CEO psychopath.
Are you 50 years old?

At those pressures most elements we think of as gases (nitrogen, oxygen, carbon dioxide) are actually supercritical fluids. Which I think of as being more similar to a liquid than a gas.

Ahaha,
I'm not, yet, but when I did work with carbon fiber testing the head of manufacturing was an over 50 white guy. A carbon fiber expert who used to do some interesting stuff with DARPA.

Lack of a pressure gradient. It's the extreme pressure on the outside of the sub and the 1atm of pressure on the inside they caused all the damage.

Looks like it was mapped to the controller incorrectly or a harness crisscrossed. Up down was rotating the vessel left right, and left right was moving it forward and back.
Also, from this video it looks like there is an interior surface of perforated metal which has lighting behind it that things were mounted to, meaning things were not screwed into the carbon fiber structure.

Could have actually been installed backwards and produced the same effect. With as screwed up as all of this was, maybe it was installed backwards, wired backwards, AND incorrectly mapped.
From my non-engineer mindset, I would want the thruster and harness both designed so that it was impossible to install them incorrectly. But the CEO did mention these were off the shelf components, so I can easily see both of these being possible. You would think you would test this **** before making it all the way to the Titanic but, then again, you would think a lot of things...

Meh... as foolish as this deal was, I don't want some new BS laws and regulations for international waters (I don't think).

Make new laws requiring an income stream to be set up into firms that turn around and give you campaign donations.

The mother ship is home.
Yeah, I'm going to say the control was backwards because installing the physical thruster backwards would be like installing the fan blades of a jet to the rear, the housing itself tells you something is wrong. Plus the thrusters themselves are typically interchangeable on sides of the vehicle but installed in the housing they are not.

I agree with you but I wouldn't count much out of the question when it comes to the Titan. No matter what the issue is, how this wasn't tested before making it all the way down is crazy to me.
From the other thread. Y'all need to watch this.
Vlogger talks about Titan Mission III. It eventually gets scrapped because a host of issues. He submerged for a few mins and went back up because no comms

At 21:00ish you see a little bit of the sub construction. I didn't realize they took the whole titanium end cap off to enter the sub. There doesn't seem to be a seal or o-ring visible.AgsOnDeck said:

For that matter, I didn't realize they towed the sub everywhere.

Yeah, I wouldn't even call that a hatch. Imagine if one of those bolts seized or threads got messed up.

Americans will join Canadians and investigate too.
Interestingly, one pending lawsuit has been dropped. A couple who paid and their trip was scrapped have withdrawn their suit. LOL.

At the surface Saturday, photos showed Canadian investigators in hard hats boarding the Polar Prince after it docked in St. John's, Newfoundland, on Saturday. The vessel, a Canadian-flagged ship that served as Titan's mothership, is the subject of an investigation by the Transportation Safety Board of Canada, officials said. Other agencies may also become involved.
U.S. authorities also are planning an investigation. The disaster was a "major marine casualty," and a probe will be led by the Coast Guard, U.S. officials said Friday. The National Transportation Safety Board will also assist.

Quote:
A pair of adventurers who sued OceanGate for fraud said they have dropped their lawsuit against the company that owned the Titan submersible.
Sharon and Marc Hagle sued OceanGate after they put money down for a trip to the Titanic wreckage site and the voyage never happened. The couple said the trip was both rescheduled and canceled, and they were told they would not receive a refund.
Trump will fix it.
$250,000 for a one way trip in a submersible.
$88,000 to stay at home and have to keep paying bills.
Life is expensive.

Based on those numbers, life is cheaper than death.
