Titanic tourist sub goes missing in Atlantic Ocean, June 2023 #2

I'm not saying it's comparable in any way but the extremis of the circumstances related to exploration, but Captain Oates did.

MOO

Its my belief that Captain Oates chose to walk out into the blizzard and end his life quickly/with less pain than his gangrene/frostbite.

Perhaps you are correct, it makes for a more Victorian rationale.

I’ve seen the power of self preservation and it’s very strong.
 
Maybe a silly question, but if they were on top of the water and had surfaced, wouldn't their Apple Watches, Phone, etc. be pinging. I have to assume at least the 19 year old has a phone on his person. At surface or right below the surface it should work no? I just saw a friends get thrown into 10 feet of water (accidentally) and the thing was ringing at the bottom of the pool?
 
“Banging on the side of the ship would be something that I’d be doing if I were trapped inside the submersible,” Marquet said. “You want to make a man-made sound.”

“Yes, it’s going to be really, really tight,” Marquet said. “There’s a probability that whatever caused the original problem an hour and 45 minutes into the original dive back on Sunday, incapacitated the crew right then and there.”

Titanic diver & logistics specialist Larry Daley said, “I’m very optimistic. I’m keeping positive.”

Bertrand Piccard, president and pilot of Solar Impulse, said, “I don’t see how they can bring a cable this deep with the robots. They need another submersible with an artificial arm that can tie the submarine to the other one and then they would surface us together.”
 
This may sound horrible, but at this point, I am hoping they imploded because then they wouldn't have been aware. The thought of them trapped, and trying to bang as they run out of air, seems like such a hellish situation.
Experts have stated that making noise/banging noise in the sub is something that the French Navy vet would know was important to do to send sonar signals to anyone who would be looking for them, and that it would be normal to send these distress/location signals on the hour and half hour. He would be trained to do this.

So I am not giving up hope. I read that the Canadian plane with sonar ability have given this information/recordings etc. to the U.S. Navy to analyze yesterday. We still have today.
 
The heartrending search to locate and rescue the Titan submersible before it runs out of its four-day air supply will be the focus of a new fast-turnaround documentary on U.K. broadcaster Channel 5.

Titanic Sub: Lost at Sea” has been scheduled to air on Thursday at 7 p.m. local time. The doc will be presented by 5 News host Dan Walker.

The ITN-produced documentary promises to “go beyond” news coverage and bring viewers up to date, while examining the wider context about the voyage, its passengers and the fascination with the Titanic shipwreck. The film will also talk to experts and look at the rise of extreme tourism.

Ian Rumsey, managing director of content for ITN, said: “This program will chart everything from the exploration itself, to the rise of extreme tourism, to the rescue attempts, but above all it will tell a very human story that has captured the nation which is about 5 people, all with families, who are trapped at the bottom of the ocean. Our expertise and heritage in fast-turnaround documentaries and reputation for responsible filmmaking means we always treat such stories with great sensitivity.”
They didn't waste any time!
 
True in general, but there is also a father and son in there together and it’s very possible he may want to save his son’s life. JMO

Very sad to think of that possibility especially if they don’t end up being rescued in the end. :(

Would the fathers death save the son when they are all trapped in a sub from which they cannot escape?

I can understand regret but not dying; they need to sit still, preserve oxygen and wait. If they are still alive.
 
I would imagine that the mother ship would have satellite or cell phone capabilities of some sort ?
Sorry to say but it would be foolish to not have extra means of communication for such a venture.

The mother ship doesn't have any current way of communicating with Titan. The mother ship doesn't know, any longer, where Titan is.

It is foolish, but it seems to be the reality here. If the mother ship could contact the Titan, all of this would be going down very differently. I thought maybe someone knew what, exactly, Titan could do if it surfaced and no one was around in that sector of ocean.

It's my understanding that it would not be highly visible on the surface, and I have heard nothing about any emergency signaling mechanism or plan. The idea was that the mother ship would be in cell phone contact with the Titan, is my understanding. I think the mother ship was using radar so far as it could to position the Titan at a spot where its descent would most likely reach the Titanic wreck area. The descent would have been affected by currents, but would generally be straight down to the ocean floor. The pings were supposed to let the mother ship know where the Titan was, but those stopped just before 2 hours into the voyage.

That's why I asked. How is the Titan supposed to contact anyone now that this has happened? Once they are at the surface? They can't get out, they can't yell, they can bang. They can barely be seen, painted white, in a vast field of white and black and blue.

The method of contact has to be automatic, IMO. No one can get out of the Titan and light a flair. I don't think it would have automatic flairs in a wet environment anyway (although surely some kind of device could have been invented - I just have not heard about anything other than very basic tools, such as a cell phone - which right now, is not working).

IMO.
 

What are ROV, P-3 and Victor 6000?​

Lockheed P-3 Orion was used before in the underwater search for the Malaysia Airlines flight MH370

Here are three of the vehicles and vessels being used in the search:

P-3 aircraft:
  • A product of the Lockheed company, it performs air, surface and subsurface patrols
  • There are more than 400 aircraft worldwide, used by 21 operators in 17 countries
  • With its infrared and long-range electro-optical cameras, it can perform submarine hunting
Remotely Operated Vehicle (ROV):
  • They are remotely controlled from the surface via a cable
  • ROV's give the crew on the surface a general idea of the depths of a search area
  • They can attach cables to lift a stuck vessel to the surface
Victor 6000 :
  • An unmanned robot which can dive up to 6,000 metres underwater
  • The robot has remote controlled arms to cut cables and hook the vessels to a ship to be lifted
 
Ok curiosity question. If the “sub” is stuck at 3500 m and the sos bangs are real, wouldn’t there have to be a physical obstacle for it to be stuck on for the vehicle not to float up or drift away? I can’t quite imagine this option as realistic. I know folks will do everything to try in case it’s real though.

If they lost communication, maybe they are unable to navigate?
