Yes, that's why I am asking what other methods they have. The sonar ping isn't working. The cell phone method isn't working. What would cause both of those to go down? Loss of electricity would remove the sonar ping, I imagine. But why isn't the cell phone working? How far do text messages (cellular data) penetrate beneath the sea? Were the pings the only method, once below a certain depth?

At any rate, neither known method is working right now. So my question remains: if the sub is now at the surface, how does anyone in the sub let rescuers know? There cannot be an easy way of breaching the walls of the sub if in fact it took over a dozen bolts to screw the hatch down tight enough. What human action could possibly manage to open that sub from inside? What methods are left to them?

There are waterproof flairs, but the firing of them would have to be triggered mechanically from inside the sub, not electronically, in this scenario. Solar-powered auto-firing flairs?

I still have no answer to the question of how, exactly, the people inside the sub are supposed to signal the ship, once they are at the surface. The idea was that the Titan would come back in roughly the same place it went down and still have cell phones working, IMO.

JMO.
Cell phones dont work underwater. Radio waves don't penetrate water except at extreme low frequency and even that wont at this depth. Undersate communication is by acoustics not radio waves mostly, and that is very limited.
 
Captain Jamie Frederick of the US Coast Guard

"We have to remain optimistic and hopeful."

Emphasizes that they need to be hopeful in the middle of a search and rescue operation.

When asked about the oxygen running out tomorrow, again he said that's just one piece of data and there are other data in play.
 
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. :(

From the practical side, I don’t know what is better to have, five people consuming oxygen in a narrow space or four people and a body in a narrow space and aerobic conditions. It is very toxic, and the door can’t be opened. It might happen naturally, though, if someone is very old, but not a good scenario.
 

Trying to determine what the sounds are​

Capt Frederick says it is his understanding the P-3 heard some noises today as well.

He now introduces Carl Hartsfield for his expertise in this area.
Hartsfield tells reporters it is very tough to discern what the noises are.

His team has "multiple sensors in the area taking the data back to the best people in the world and feeding this back to the team so they can make decisions".

"They have to eliminate potential manmade sources other than the Titan," he adds.

 
They do have a second submersible and that one is a bright yellow. One of last year's passengers had his picture taken next to a bright yellow submersible in dry dock:


The second picture shows the same man, Mr. Reiss, at the embarkation point and the Titan is white (so probably the same one that's down there now). There's some safety theater going on, as well, because Mr. Reiss is wearing a life vest. To be sealed inside a tube with no escape except by help of human hands.

The Reiss family apparently went together and did get to see a portion of the Titanic through the porthole. Son is shown wearing safety gear and what looks like a cell phone. Or maybe it's something else, can't tell.

IMO.

Area of the search is now "two times the size of Connecticut," Coast Guard says​

Capt. Jamie Frederick, the response coordinator for the First Coast Guard District, said Wednesday the surface search for the missing submersible is now "approximately two times the size of Connecticut and it is up to two-and-a-half miles deep."
He said that rescuers have "exponentially" expanded the area of the search, and it is expanding "every hour."
He noted that searchers have to factor in "ever-changing weather conditions" during their operation.

Searches around site of banging sounds have not yielded any results so far, Coast Guard says​


Searches around the area where noises were identified in the Atlantic Ocean on Tuesday have "yielded negative results," the Coast Guard said, adding that crews are still efforting to locate what made the banging sounds on Wednesday.
"We don't know what they are," Capt. Jamie Frederick, the response coordinator for the First Coast Guard District, said of the noises.
He said ROV equipment was relocated to look for where it was coming from, and data from the Canadian aircraft that first detected the noises has been shared with experts from the US Navy.
This data will be “considered in future search plans," Frederick said, adding that so far that data has been studied so far is "inconclusive."

 

More equipment on the way​

We're now hearing there is a lot of equipment flowing in from St John's.

The French team coming in is bringing some "state of the art equipment".

The US Coast Guard plans to have more assets in the area soon, which will be placed in the spots they determine to be best for the search.

 

Here's the team that is assisting in the search efforts for the missing sub​


The search for the missing submersible called Titan involves surface and subsurface elements, according to Capt. Jamie Frederick, the response coordinator for the First Coast Guard District.

The location of the search is 900 miles off the coast of Cape Cod and 400 miles southeast of St. Johns, which he said makes it "difficult to mobilize large amounts of equipment quickly."

In light of these details, Frederick said the following was enlisted to help in the search efforts:
  • Currently, five service assets are searching.
  • There will be a total 10 surface assets in the next 24-48 hours.
  • There are two ROVs actively searching.
  • Several more are en route and will arrive by tomorrow morning.
  • There are two back-to-back P-3 flights — one is ongoing — which provides a total of 14 hours of continuous on-scene coverage.
  • Two C-130 flights — one ongoing now — through the day and into the evening.
 
I don't understand how they don't know how many food rations they have aboard.

This information should be readily available. It sounds like the Titan organisers don't know themselves? That's quite concerning in terms of Titan's overall organization if that's the case MOO.
 
Captain Jamie Frederick of the US Coast Guard

He doesn't know what the sounds are. Inconclusive.

But they heard the sounds again this morning. So they are not giving up hope, and the U.S. Navy is analyzing the sounds and Frederick said that they have moved their assets to the area where the sounds were heard on sonar. So if the sounds prove to emanate from the Titan sub, then they are at least looking in the right place. Captain Frederick re-iterated this several times.
 
Looks like 4 or 5 ships currently heading towards the area.

'We have to remain optimistic'​

The media update is over, but we are going to bring you some more details of what was said.

One important line came from Capt Frederick when he was asked if he was still optimistic.

"We have to remain optimistic and hopeful when we are in a search and rescue case," he replied.

"We are in the middle of the search and rescue case. Sometimes we don't find what we're looking for and you have to carefully consider all of the factors.

"There are a lot of factors you have to consider. After considering all those factors, sometimes you're in a position where you have to make a tough decision. We're not there yet.

"If we continue to search, potentially we could be at that point... And that's a discussion we will have with the families long before I am going to discuss here publicly."
