Race to find Titanic tourist submarine with British billionaire and four others aboard that has vanished

In the U.S., at 18 you are a legal adult (age of majority) when your parents are no longer legally responsible to you. Besides the usual things like joining the military or getting your drivers license on your own, you can also enter legal contracts.

Some states may have an age restriction on things like being 21 to buy alcohol. Also, you may be considered a legal adult before 18 if you are granted a court order for emancipation, obtain certain educational degress or meet your defined state statue as an exception like getting married as a minor.

There also have been times that kids have talked their parents into signing permission slips for them to do something that they probably shouldn't have done. But in this incident, it wasn't the case.

Not sure what the laws are in other countries. Also not sure what country this contract in question would fall under.

Since this happened in Newfoundland Canada and the age of majority is also 18, then it would all be considered legal. Drinking used to be legal at 18 here but has since increased to 19.

James Cameron is indeed an expert!

Not only is he a Film Director…he is also a deep-sea explorer.

He has dived to the Titanic shipwreck site 33 times.

He knows the environment down there…he knows the sounds made by a shipwreck and knew the banging was not coming from the Titan.

Yes, James Cameron knows what he is talking about ... that is why they reached out to him for his expert opinion.

Cameron, who is a submersible designer himself and has designed vessels that can dive to depths three times deeper than where the Titanic rests, called the carbon fiber construction of the Titan as "fundamentally flawed."

I followed the events of this sub and worried that they wouldn't find it in time. Reminds me of MH370. I feel bad for the families of course, but I would have thought twice before getting into what I saw one person called it a pod. I'm sure the lure of the excitement to see the Titanic was a draw to them. Heck, I would have liked to have gone down and seen it, but in a much larger sub. The Nautilus would have been OK.

Do they know how deep the sub went before imploding?

1600 feet from the titanic.
 
From CNN ...
It’s unclear where or how deep the Titan was when the implosion occurred, but the Titanic wreck sits nearly 13,000 feet (almost 4,000 meters) below sea level. The submersible was about 1 hour and 45 minutes into the roughly 2 hour descent when it lost contact.

At the depth the Titanic rests, there is around 5,600 pounds per square inch of pressure – several hundred times the pressure we experience on the surface, according to Rick Murcar, the international training director at the National Association of Cave Divers.

I'm thinking probably just about when they lost communication with the ship... which would be an hour and 45 minutes into the mission. The debris was found not too far from the Titanic, but that's just where it would have landed/settled. Whole thing is so sad. :cry: @oldman
 
I haven't read through the 13 pages of posts, so if not already posted, they have found a debris field, and it's clear the sub. imploded, and there are no survivors. At least, the crew would never have felt anything. The sub. was an experimental craft, going to extreme depths with immense pressures, so there was always the good chance an implosion was likely.

Yes...James Cameron is a brilliant man, thanks for acknowledgng that.

That information is most likely inaccurate. They cannot speculate how deep the titan was before it imploded. I was mistaken by what I initially read. My apologies.

Correct. They don't know at what depth the implosion occurred but they were about 1.5 hours into their descent when communications were lost and that coincides with when oceanographic acoustic systems recorded an unusually loud noise in that area of the ocean. The complete descent was planned to be about 2 hours so if they were on track, they would have been around 9,500 feet down, of their planned 12,500 ft descent when the implosion happened.

My guess is they will find the carbon fiber tube of the craft was the component that failed and caused the implosion.

That must have been some pressure to break through a carbon fiber tube. When I first went to college to be an engineer, we studied many metals, but I don't know about carbon fiber. It was fairly new during my first college years. However, I do have a carbon fiber tennis racket and golf club and they do take a beating, especially my tennis racket when I get frustrated and throw it into the fence.
 
Titan was not a submarine…it was a submersible.

The difference is a submarine has enough power to leave port and come back to port under its own power, according to the experts.

A submersible like the Titan has very limited power reserves so it needs a mother ship that can launch it and recover it.

This means it does not, unlike a submarine, have the power to dive down to the bottom of the ocean and come back under its own steam.

That alone would indicate, the whole thing was doomed from the start…a suicide mission.

The mother ship Polar Prince escorted Titan to Newfoundland, which is the nearest point to the Titanic.
The mothership lost contact after two hours, so that is another telling fact.

I am a little confused. How did it get to the bottom? Did it just sink under its own weight? It looks more like a pod than a sub. If there is no power, how was it going to ascend? Was the mother ship going to put a winch around it?
 
They have said that a video game controller was used in the Titan .... unbelievable if true.

From what I understand the mother ship can remotely control the vessel under normal circumstances.

Interesting to note OceanGate, the company responsible for the Titan, fired employee David Lochridge after he expressed concerns about the submersible’s safety.

I read that the force of the water at that depth increases the weight of the vessel and probably that's why it was able to sink so far down.

This from republicworld.com: (written while still missing)
"Titan, the missing submersible, has been designed in such a way that its ballast and heavy weights - which hold it underwater - would be automatically released after 24 hours which would send the sub floating to the surface, Aaron Newman, an investor in OceanGate, who too went on a Titanic expedition on board the Titan in 2021, said."

My last response was actually a lot longer but I feel uncomfortable writing in this thread that’s specifically about these people who lost their lives on their journey. It seems somewhat disrespectful to discuss a wonderful journey in the midst of this horrific tragedy however, I’m sincerely interested in your voyages and wonder if you might be interested in starting a thread or journal of your own here so I might bombard you with a slew of questions? Many others might also be interested. I’ve never personally met anyone who has done something like this and find in incredible fascinating.

I see your point, I think you should start a new thread. I'd really like to hear your story, and more from @JustDave , and others too.

As I understand, this wasn't the first dive, so perhaps there was a cumulative effect of the pressure weakening the structure over many dives. There must have been some flexing of the structure over and over until...

I just posted there. I have no idea where it will go. People are usually curious about me doing it, but only a handful have showed any serious interest. For me of course it was a life long dream, and the biggest adventure of my life, and I remember it and the people I met with a great deal of fondness.
 
Just saw this, suggests as many have said it was a quick death.

When a submarine hull collapses, it moves inward at about 1,500mph (2,414km/h) - that's 2,200ft (671m) per second, says Dave Corley, a former US nuclear submarine officer.

The time required for complete collapse is about one millisecond, or one thousandth of a second.

A human brain responds instinctually to a stimulus at about 25 milliseconds, Mr Corley says. Human rational response - from sensing to acting - is believed to be at best 150 milliseconds.

The air inside a sub has a fairly high concentration of hydrocarbon vapours.

When the hull collapses, the air auto-ignites and an explosion follows the initial rapid implosion, Mr Corley says.

Human bodies incinerate and are turned to ash and dust instantly.

well please God that's what happened to these 5 people.... and that it happened long before they started to run out of air, and realised they were stuck down there
