AP News: A search is underway for missing submarine that takes people to see Titanic
A search is underway for a missing submersible that carries people to view the wreckage of the Titanic. Canadian officials say the five-person submersible was reported overdue Sunday night about 435 miles (700 kilometers) south of St. John's, Newfoundland and that the search is being led by the U.S....

It has 96 hours of life support, I have faith.
I am hopeful, but not necessarily optimistic...if it lost power and descended below crush depth, no amount of life support is bringing them back.
Someone else in the other thread about this said they have magnetically attached ballasts that can be jettisoned so the sub floats if power is lost.
It's also designed to go down to the floor where the Titanic is. Was it also passing over deeper water? I'dve assumed they'd release it from a boat above the titantic fairly directly.
Well with all that taken into account, the fact that we haven't seen any evidence of the sub yet is a very bad sign.
But apparently they cannot open the hatch from the inside, so even if they are on the surface, the oxygen will still run out if they're not found.

I assume there is also no vent or similar to let air in?
This may be true, but how much time does it take to surface to avoid decompression sickness if they are found? This, of course, assumes that the surface in the same vehicle.
The inhabitants of the submarine aren’t under pressure directly like scuba divers are, they’re at atmospheric pressure while inside which is why the pressure hull needs to be so strong to resist the hundreds of PSI outside - it’s the pressure difference that crushes things in this case. If they are rescued there’ll be no requirement to decompress slowly as their bodies were never under compression and at risk of the bends (when nitrogen bubbles form in your blood with often lethal results) to begin with.
The inhabitants of the Kursk during that submarine disaster were subjected to high pressure in their last hours but that was because the water slowly flooding their compartment compressed the air like a piston, this isn’t a concern for this submarine as it goes far deeper than the Kursk and the slightest fracture to the hull would kill them instantly in a violent implosion.
