A search and rescue operation is underway for a submarine touring the wreckage of the Titanic

I would not go on a tour like this even if it was free, let alone for $250,000 for this reason, might not make it back to the surface?!!

After 96 hours all on the sub will be dead, that's when the air supply runs out, if it did not implode?!! Even if they find the sub before the air runs out, how would you bring it back up to the surface at extreme depth?!!

[FONT=cnn_sans_display]The US Coast Guard launched a search and rescue operation Monday for a submarine that went missing during an expedition to the wreckage of the Titanic, CNN partner CTV News reported.

[FONT=cnn_sans_display]The group conducting the trip, Oceangate Expeditions, said it is “exploring and mobilizing all options to bring the crew back safely.”
[/FONT]
[FONT=cnn_sans_display]“Our entire focus is on the crewmembers in the submersible and their families. We are deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to reestablish contact with the submersible,” the group said. “We are working toward the safe return of the crewmembers.”[/FONT]

[FONT=cnn_sans_display]The submersible holds up to five people, the company says on its website. It wasn’t immediately clear how many people were on board.

[FONT=cnn_sans_display]The Titanic infamously hit an iceberg on its maiden voyage and sank in the North Atlantic Ocean in April 1912, killing over 1,500 people. The wreckage of the Titanic, discovered in 1985, sits in two parts at the bottom of the ocean nearly 13,000 feet below the surface southeast of Newfoundland.

[FONT=cnn_sans_display]More recently, costly private tours have been offered to tourists, allowing people to see the wreck up close.[/FONT]

This is your chance to step outside of everyday life and discover something truly extraordinary,” the website said. “Become one of the few to see the Titanic with your own eyes.”

I'd go if it was free...or only $250. LOL

Unfortunately, I think these poor bastards are toast.

From the link: "As a safety feature, the sub uses a “proprietary real-time hull health monitoring (RTM) system” that analyzes the pressure on the vessel and the integrity of the structure, the company states. It also has life support for a crew of five for up to 96 hours, the website states."

It's been about 24 hours so only 72 hours of air left. The monitoring system should have indicated a hull breach, which would be instant death at that depth.

It's possible they got hooked on the ship but that doesn't explain lost comms.

380 atmospheres of pressure. One atmosphere = 14.7 lbs per square inch. 380 X 14.7 = 5,586 PSI. If the hull breached, they'd be smashed flat inside the sub almost instantly.

Those subs have tons of safety features and backup systems so if it just disappeared there may very well have been a problem with the hill and the pressure just crushed it

At least it would be a painless death

Agreed on redundancy. Any major problem at that depth, like being in space, becomes exceedingly problematic.

Agreed on painless if crushed. If hung up down there without comms, they might be gettin' a little worried.

There's no way to do a transfer down there. If the sub is intact, it'd have to be carried to the surface. Rescue subs are rare, but remote submersibles are more common. I think we'll know in another 24 hours if the sub is intact or in pieces.
 
You would think a company running tours at that depth would have rescue subs on hand but if not I imagine they are in for some trouble as they should be
 
One of the passengers is/was a billionaire.

You'd think they could attach some kind of cable to the ass end of the thing.

Haul it back up.

Anyway, the one big take away from this is....

"Oh, you think YOU got problems????" :eek2:
 
It seems to me there is zero percent chance of survival if there is a serious accident at 12,000 feet deep on the abyssal plain.

Yeah if it's still intact and not tangle in the wreckage of the Titanic, an un-man submersible could put a cable around the skids of the sub and pull it up?!! You don't have a lot of time left, the air supply is running out?!!

Ninety six hours is what they said.

With about twenty four of it already gone.

I imagine subsurface ocean currents would wreak force and havoc on 12 thousand feet of trailing cable in the water column, and render navigation practically impossible.

Not if it's caught in the wreckage.

Lots of dynamics going on down there. If the sub is hooked on wreckage, an ROV might be able to free it. The sub has drop weights. If free, it simply drops the ballast and floats to the surface.

Sounds like one of two problems: trapped by wreckage or it imploded.

If freed, the sub could drop its ballast and float up by itself. If it's wreckage, it'd have to be hauled up.

I read that contact with the submersible was lost about one hour and 40 minutes into the dive. A quick Google search says a normal dive to the wreck takes two and a half hours. So whatever happened must have happened during descent, and not while exploring the wreck.

3 scenarios probably cover what happened to the Titanic submersible, experts say. Only 1 has much chance of survival.

Rescuers are racing to find a submersible that went missing with five people on board.

The crew, who were on a tour by OceanGate Expeditions, could lose oxygen by Thursday afternoon.

Here are three likely scenarios of what could have happened, according to experts.

An extensive search and rescue effort is underway after a tourist submersible, carrying five people, went missing while on a dive mission to the Titanic shipwreck on Sunday morning.

The 23,000-pound Titan vessel, owned by OceanGate Expeditions, went off the radar around one hour and 45 minutes into its descent off the coast of Cape Cod, Massachusetts, according to the US Coast Guard.

The crew — which includes a British billionaire adventurer and a father and son from Pakistan — may run out of oxygen on Thursday afternoon, Eastern Standard Time, experts predict.

As the rescue efforts continue, here are three scenarios of what could have happened.
