re: Titanic tourist submarine goes missing

This has probably be asked. But would the Sub Captain keep descending after he knew they lost communication? Especially if he knew they had no form of navigation or backup communication.

Didnt want to lose profit .

I suppose it doesn't have a toilet.

Well if it does. . .

Retired Navy submariner says he was told the sub was trying to release ballast at the time they lost comms, indicating they were too heavy and descending too fast

This would be murder I think.

The "murderer" was on the sub with the victims. I think murder would be tough to convict. These aren't unsuspecting people going on a joy ride not knowing anything about the sub. They're millionaires with the ability to have people do their due diligence. And they signed waivers saying death is a possible outcome. Negligent manslaughter I could see maybe.

This is a scene from the search crew at the moment.

Probably a moot point, but the sub has officially run out of breathable air based on the Coast Guards estimates.

OceanGate's calculations showed the cylinder that forms the center section of the crew compartment should have a wall thickness of 4.5 in (114 mm), which they rounded up to 5.0 in (127 mm); it consists of 480 alternating layers of pre-preg unidirectional cloth, laid in the axial direction, and wet-wound filament, laid in the hoop direction. The cylinder was built in 2017 and cured at 137 °C (279 °F) for 7 days.[19] The entire pressure vessel consists of two titanium hemispheres, two matching titanium interface rings, and the 142 cm (56 in) internal diameter, 2.4-meter-long (7.9 ft) carbon fiber wound cylinder – the largest such device ever built for use in a crewed submersible.[23] One of the titanium hemispherical end caps is fitted with a 380 mm-diameter (15 in) acrylic window.[19] In addition to the crew compartment, Titan includes a landing skid structure and outer glass fiber composite shell, both bolted to the titanium interface rings.[19] Overall, the Titan is 670 cm × 280 cm × 250 cm (22.0 ft × 9.2 ft × 8.2 ft) and weighs 9,525 kg (20,999 lb) with a maximum payload of 685 kg (1,510 lb). It moves at up to 3 kn (5.6 km/h; 3.5 mph) using four electric thrusters, arrayed two horizontal and two vertical. The vessel carries sufficient oxygen to sustain a full complement of five people for 96 hours.[9]

Titan is equipped with a real-time acoustic monitoring system, which OceanGate claims can detect the onset of buckling in the carbon fiber hull prior to catastrophic failure.[2] Rush holds a patent on the system.[24]

as per wiki

I know right,

captain: "we can monitor the complete condition of the hull"
red alert light comes on
passenger: "hey what's th....pop

Hull's all like, "hey, I'm deflecting... and I'm done."
