So the best way to die is peacefully, in your sleep. No trauma, no terror....just slumber. May we all be blessed enough to pass in that manner when the time comes.

Yes, as long as it's not a drug overdoes. Kids are being found by their parents dead on couches and in bed from fetanyl OD.

Thank you for the information about the debris field around the Titanic which could be recognized as being “new” to that already identified.
Don’t think that info is very well known.

Another side effect of OBiden’s open invasion policy. Biden’s got so much blood on his hands by now, it’s probably even more than the Clintons have on theirs. Amazing how evil these people are.... and how they are seemingly thriving in that evil.

Stern is missing and some distance away from this site.

Yes, something like a half mile away. Debris field is in between.

Yes, that and sex slavery, and they keep saying they are against slavery.

Beats suffocating. If it is the Titan. They should find something to identify it. USS Thresher went down off Maine in 8000 feet of water. They identified it in 1993 soon after the event. It hit crush depth. They were fighting the casualty and knew they were in trouble but didn’t know when it failed, they say.

I always said I want to die in my sleep, like grampaw - not screaming in terror like the people who were riding in the car with him. :-o

Here’s my question. Does the coast guard actually know the details of the original debris field? Who really knows this.

Good question. I’m speculating they have experts who have previously mapped
Titanic debris field.

Well, if they find a bright silver titanium ring, or some carbon composite shards, they can be pretty sure they aren’t part of the Titanic debris, although they are now a permanent part of the debris field.

I think it had a catastrophic hull failure and it was over in a second.

In the movie Titanic at the very beginning when they were diving on the wreck the actor said the window was 9 inches thick. He said if it cracked they would be dead in Micro seconds with the implosion that would happen!

I would imagine it would pretty easy to differentiate between Titanic and debris from a modern day sub.

Yep, not alot of carbon fiber back on the titanic.

Fox reported a source told the BBC a landing frame and a rear cover from Titan has been found.

Keep a lookout for 497 1/2 feet of rope.

To me, finding a debris field means that the submersible almost certainly imploded, if the debris is in fact from that craft, which should be easy to determine.

If they were 1 hour 45 minutes into a 2.5 hour descent, their depth was somewhere around 8750 feet, thus the external pressure would have been approximately 3900 PSI. From what I read about the failure properties of carbon fiber, it occurs instantly and catastrophically. This vehicle had been on previous dives, thus the carbon fiber no doubt experienced some level of cyclic stress, meaning that minute weaknesses likely developed with the slight compression and expansion, however small, which happens due to such pressure extremes.

Understand that things which our minds think of as rigid actually flex quite a bit when exposed to large forces. Standard high pressure cylinders such as those used for scuba diving, commercial gases, etc must be hydrostatically tested every few years. The way they test them is to submerge them in a precision calibrated water-filled testing vessel. The tank is then pumped up to a certain pressure, and the amount of water which spills out due to the amount that the tank expanded under that pressure is carefully measured. If the amount of water exceeds the established safety limits, then the tank is considered to be unsafe, having “failed hydro”, and is removed from service.

Back in the 1980s one of the major scuba cylinder manufacturers used a different aluminum alloy for some of their 3000 PSI tanks. Eventually some of these tanks started failing under pressure, sometimes catastrophically (as in exploding) causing at least one fatality. Analysis revealed that over time, repeated filling and use of the tanks was causing tiny cracks to form around the neck of the tank, but inside the metal where they could not be seen by a normal visual inspection. The phenomenon was called Sustained Load Cracking (SLC). Tanks made from this alloy were pulled from service, and in fact the manufacturer offered a swap program for them. While it was technically possible to detect SLC through the use of a testing device which generated an electrical current through the tank, overal the recreational diving industry pretty much refused to fill these tanks any longer. I myself owned one, and when I learned about SLC, I immediately scrapped it. One does not take chances with high pressure, or with the ocean.

As another example of the effects of pressure on seemingly rigid objects: A charter captain with whom I used to dive had a son in the US Navy submarine service. He got to go on a short dive when they did a special cruise for immediate families. He said one of the most eye-opening things was when they had him tie a string taut from one side of a compartment to the other, prior to descent. At depth, they took him back to that same compartment, and the string was hanging down loosely, halfway to the deck. That’s how much the submarine had compressed due to the external pressure, and this is only a fraction of the depths we’re talking about here at the Titanic site.

Under these extreme pressures, close to 4000 PSI, and with carbon fiber failures occurring catastrophically and pretty much instantaneously, the implosion would probably happen in a few milliseconds. Human reaction time is 150 milliseconds at minimum, so this would almost certainly be a literal case of the event being over before they even knew it was happening.

This is a tragedy no matter what the mechanics were, but compared to spending days in the dark, freezing at 37° as the oxygen supply slowly ran out, implosion is a far better way to go.

If this did in fact happen at around 8750 ft, there would no doubt be some spreading and drift of the debris, due to the significant currents which are usually found at this site. And of course lighter materials such as carbon fiber fragments would drift farther. However, in my opinion the telltale objects, and those probably most likely to be found, are the titanium end caps. Those would survive an implosion mostly intact, and should provide a solid return on a side scan sonar, if the ROVs being used are so equipped, as they probably are. Plus, they are large, thus would be more easily spotted by visual means as well. The metal “skids” beneath the hull should also survive relatively intact, and would provide further positive identification.

It will be interesting to hear the details of what was found when the announcement is made.

From Daily Mail:

The landing frame and rear cover of the missing Titan submersible have been discovered on the ocean floor, according to experts involved in the search, who say it points to the vessel suffering a ‘catastrophic implosion’ that will have claimed all five of the lives on board.

The US Coast Guard announced on Twitter that the ‘debris field’ had been found on Thursday. They are yet to confirm what exactly was discovered, but Richard Garriott, President of the Explorers’ Club, tells DailyMail.com his understanding from the teams involved in the search is that key components of the sub were among the items.

It would mean the sub suffered a crack and imploded under the underwater pressure, instantly killing all five men on board.

‘A debris field implies there’s a break up of the submersible and at that depth, because we know that they lost communications at around 3,300m… so that really indicates what is the worst case scenario which is a catastrophic failure, an implosion.

‘The only saving grace is that it would have been immediate, literally in milliseconds and the men would have no idea what was happening,’ David Mearns, a friend of two of the men on board, said during an appearance on Sky News in the UK this evening. He added: ‘My worst fears have now been realized.’
