USCG involved in search for missing submursible

From the article:

“The Titan utilizes SpaceX's Starlink satellite communications system when at sea.”

What does that mean? As in communicating with others? Directional?

OceanGate CEO explains why he didn't want to hire '50-year-old White guys' to pilot subs

OceanGate Expeditions CEO Stockton Rush, who is onboard the missing Titan submersible, once explained in an interview why he didn't hire captains with military experience.

French Rover is on the ocean floor, and sounds (altho less in number) at 30 min increments still occurring.

Still hopeful 🙏

As an aside: my sons offshore sailing training block group last summer were guests at the Oceanic Institute in Woods Hole. Some of the people they met and listened to are involved in this search and rescue. Not the Navy’s Alvin vessel, but people and other equipment.
 
Presser at 3 EST, with the Rear Admiral, USCG.

I remember reading about Alvin in the 60's, especially when it sunk in '68. Pretty cool that it is still going strong. Not the same "Alvin" though. I expect that everything has been replaced once or twice and it is "Alvin" in name only. Surely the bathysphere is new, because every dive reduces the elasticity of HY80 steel.

Trieste was another one that intrigued me. That bathyscaphe went to the floor of the Challenger Deep in the Mariana Trench. I would have to look it up, but I think to this day - only 2 humans have been there - and they were in the Trieste (back in 1960).

The personnel sphere and much of the frame and control assemblies of Alvin are made of titanium, not steel. The sphere was last replaced in 2012.

I did not know that. That seems stupid. The Soviets lost an Alpha that used titanium and then retired the entire fleet because of the incompatibility of titanium with deep dives. I just assumed that anything American made would use HY80. The more you know!
 
Just watching the Coast Guard press conference. One of the speakers said that they found the "front part of the end bell" and then some distance way the "rear part of the end bell". So this pressure hull was a cylinder with a half-sphere "end bell" on each end. I had assumed that the occupants were inside a pressure sphere, not an elongated tube. Now is makes sense to me why it imploded.

Sad.
 
If no rescue was going to be the outcome anyway, I found myself thinking I hoped for implosion, sudden, swift, final - not hours and hours in the cold and silent dark waiting for the inevitable.

I am glad something tangible has been found. Better for the families to create a starting point for knowledge, acceptance and grief, painful though it will be.

Ya … press release said something to the effect that crew members are ocean conservationists … or something along that narrative …. Well, I don’t know if I can agree with that with all the energy that went into this rescue mission … and now the debris they left behind

Leave the Titanic alone … sheesh …

Missing submersible chief's wife is descendent of Titanic victims, New York Times reports

Stockton Rush, one of those aboard the missing submersible in the North Atlantic, is married to a descendant of two first-class passengers who died when the Titanic sank in 1912 after hitting an iceberg, the New York Times said on Wednesday.

I wonder if they will retrieve the wreckage? Or leave it? WTH all the equipment on site already, seems to make sense to recover.

With civilian space and sea exploration, sadly, this is what we have to expect. They are both unchartered, no man’s land. Kind of interesting to ponder what will come from this….

I just did the Pressure cumulative force equation for pressure at 12,500 foot @ a seawater density of 65 lb/ft^3 … integral comes out to —>

~ 5640 psi ~

Trieste intrigued me too. It had a crew of two. One of them onboard was a US Navy Lieutenant named Don Walsh, a submariner. I remember reading about the operation long ago. I could never even imagine going down that deep. May the crew and passengers of the Titanic rest in peace.
 
I was wondering about the Navy recording capability component.

There are some saying sending rescue teams was a waste of time and resources and also placed others at risk.

If the Navy heard an implosion at the last recorded comms with the vessel, then looking for them to be rescued was really more to make people/families think there was a chance. I kind of think that's cruel. The last few days, I've thought about what being in that tube would be like. Hell for sure. If someone were to lose their mind it could have gotten violent. Which makes it even scarier. If there had to be a sad ending, an implosion that killed them before they knew it was happening is the kindest outcome.

It's also disturbing how many experts are speaking out about how the CEO and founder has stated in many interviews that he used cheap off the shelf parts.

Who would sign up for that in their right mind?
 
Not a surprise. The Navy heard the Scorpion go down in 1968. I would assume that the sensors are better and more plentiful, now.
