Titanic tourist submersible goes missing

If the Navy 'knew' why would they spend 10s (maybe 100) millions of $ continuing to search, adding in the US and Canadian coast guard and having other experts time being used?

If they knew for certain with evidence, they would have said so asap. If they had a hunch, that is a different story.

Strongly suspected is probably the right word. They detected an acoustic events consistent with an implosion at the time and location the vessel lost contact.

I was at the Titanic site a couple months ago. We boarded Holland Amerika Line’s ship the m/s Rotterdam in NYC, for the historical 150 year anniversary passage to Plymouth, UK.

At the Titanic site we came to a full stop and for 5 minutes crew and passengers stopped doing whatever they were doing and in silence remembered the people who died there.

I wish the submarine tourism stops.

From what I read, the Navy did inform the search coordinators as soon as they knew. It was their decision (the correct one at the time, IMHO) to continue the search on the off chance that was a coincidence. James Cameron's interview was probably the most informative on this aspect. Everyone "knew" the truth but it wouldn't be right to give up at that point.

Reading between the lines, it seems like the ROV which "discovered" the wreckage might have been sent to that spot based on the Navy report.

What isn't clear is exactly how quickly the Navy knew. Did some Navy crew member jump up and shout "something just imploded!" or did they review reams of data after hearing about the loss? An adversary would love to find out how long they have before getting our attention. It's probably better we don't know.

Well, there is your answer above...

The Navy knew where and when there was an event immediately as they have been listening (and distinguishing the various sounds with pinpoint accuracy) in the oceans since the 1950's. The now long retired and declassified SOCUS system will give an idea to the curious. Surely replaced with better technology. This is beyond the local Sonobuoys deployed to detect subs/etc.

Interesting article on the viewing angle of Stockton Rush.
Looks like this was destined to happen:

BBC News - Titan sub CEO dismissed safety warnings as 'baseless cries', emails show

As mentioned further above all other passenger carrying vessels need to be inspected and certified...

I don't really have an opinion to share on the submersible; just following the thread with normal curiosity. However, from earlier in the thread there seemed to be a general lack of understanding within our community about SAR zones, specifically why the US was leading the search in that area. Seems to me that anyone cruising offshore should have a clue about who's going to rescue them if things go pear-shaped. This site has a pretty neat interactive map that helps you work that out: https://sarcontacts.info/

That's a good resource. Thanks.

Carbon Fiber...... What could possibly go wrong? "but the numbers say it's okay!"

Cheechako,


That photo almost belongs in the Joke Thread.
It was funny when it happened.

And two different materials. It’s not even all carbon fiber. Metal with carbon fiber. Different rates of contraction and expansion under pressure. That’s the worst part of it.

Plus, it’s in compression. Composites do best when they are in tension.

Definitely Monday morning quarterbacking or whatever, but it seems very obvious not to build it like that.

kinda reminds me of these strong man competitions...where a competitor must hold his arm out parallel to the ground, while holding a heavy ax in his hand.
the strong man can accomplish this for several minutes, until the strain becomes too much for the arm/shoulder muscles, and the arm drops..
while the arm is still attached to the shoulder, the connection is, for all intents and purposes broken...

in a similar manner.....material matter in a structure can endure "x" minutes, before reaching it's elastic limits...and breaks...still attached, but broken....

not sure that this is a good analogy, but it's how I think of it...

Debris, from the submersible's nose cone, pieces of its hull, a section of the tail, and "presumed human remains" have been recovered, from the wreckage area of the ‘Titan’ submersible.
The remains were recovered “within the wreckage” of the submersible, and will be analyzed by US medical professionals.

The U.S. Coast Guard MBI is working in close coordination with other national and international authorities, including the United States National Transportation Safety Board, Canadian Transportation Safety Board, French Marine Casualties Investigation Board, and United Kingdom Marine Accident Investigation Branch.
