Tourist mini sub missing off titanic

One way or another, they're dead. It's too bad but they paid their money and took their chances.

If they did not die immediately, as soon as the problem appeared, they all took a dump at the same time.

The are not dead yet!

I'm still praying for their safe recovery... There I said it!

I do know some sub guys and they have pretty much hit all the points made in this thread, especially the lack of distress/location signal....leading to the conclusion it may have been a structural failure. I only hope whatever happened was catastrophic and they died quickly.

If they were on the surface they would have been found by now.

I still have ownership in a composites company and the details of the Titan build will be of interest.

OK thanks... What could they be doing right now to find them? "Sonar?"

This is a bit more in my realm.

The depth of the potential mishap is a real problem in terms of getting a sensor near the mishap. Without going into geek-speak, there are definitive, measurable performance ranges of "active" sensors like SONAR. However, I have been out of the game for along time and do not know what is the state of the art at this time. The problem hasn't changed, the sensors may have.

The composite structure is also an issue, especially if they are on the sea floor. SONAR basically "paints" with energy in the water column and provides the SONAR operator with, frankly, some very rudimentary range and bearing info - in this case that will be hard.

My guess, guess only, is that there are now fields of passive sonobuoy's in the area listening for unusual sounds. But again, depth is an issue. Tactical sonobuoy's don't need to get beyond the operational depth of submarines, which others have mentioned is not close to where the Titan may be.

The article linked earlier was very good concerning the Coast Guard and lack of anything other than sea noise.

There is a lot more sound in the water than most folks know.

I just hope is was quick.

It was in the news that they have heard banging from around the search area so, I would assume that these poor souls are still alive but, yeah, time is definitely running out for them.

I of course also hold hope for a miracle but it would truly be a miracle if they were alive and rescued at this time. As Mr. Seahawk pointed out above, there are apparently lots of random noises in the ocean that could account for the banging.

There is nothing wrong with hoping; this story has been very disturbing to me and I assume millions of others. Just a god awful way to die if it was slow.

I heard something on the radio this morning that confused me…the reporter said that it was supposed to be a two hour trip? I thought I heard earlier that just getting down to the Titanic took longer than that?

So the sub had X number of hours of air for a crew of 5.

What if not all 5 are alive?

What if the problem killed somebody? Or what if one of them in an act of true altruism took himself out to give the remainders more time? What if members of the crew conspired to extinguish somebody to save themselves?

[HobieMarty]

Just for clarification.

That reminds me of this Mr. Ballen Episode.

In Bill's defense... Humor is often used to help deal with a tragic situation.

Typical Kiwi... LOL

I’m seeing reports that a search aircraft is hearing banging noises.
How does that work? How can an aircraft pick up faint underwater sounds??

probably Orcas playing pong...

The pic below shows sonobuoy's being loaded or unloaded from a SH-60. There a number of different types, both active and passive...meaning one pings to get data, the other just listens.

We could carry 25.



This aircraft, a P-8, carries a bunch more. I bet they were all over this, as were the Canadian's.



The sonobuoy's are in RF comms with the aircraft, the data can be shared by multiple aircraft once the buoy is deployed.

This feels like a Malaysian Airlines 370 situation. As in, they may never be found.

On the positive side, if they are found before oxygen runs out (another day, max? - assuming no "preemptive action" taken) a French ship with a submersible able to operate at those depths is supposed to be on site by this evening.

Carbon fiber space craft. OK. Carbon fiber submersible, ain't no way. Capt Ahab can give a better answer, but the compression cycles would be killer on cf.
