Oceangate Statement, “We now believe that [all crew] have sadly been lost.”

Or are you referring to the insufficient number of lifeboats? I haven’t seen any evidence that other ships carried a larger number of lifeboats relative to their size.

If the window failed, I would expect to have none or one bell separated from the tube, but not both. I imagine the glass being shot inside the tube and the water jet would vaporize the people inside and maybe blow one bell off.

If the tube failed, would expect both bells to be sitting on the ocean floor.

I’m not a professional mechanical engineer, just a guess.

If it was the Plexiglas that failed (or other part of the end bell assembly), I'd expect the pressure to quickly equalise though the failure point and the carbon fibre shell to remain relatively intact and hold those end bells together.

Though, I'm not an engineer. Maybe the rapid change in loading could result in the carbon fibre shattering.

Ironically.

However there may have been multiple noise events.

> Rush's experience and research led him to two basic conclusions: one, that submersibles had an unwarranted reputation as dangerous vehicles due to their use in ferrying commercial divers, and two, the Passenger Vessel Safety Act of 1993 "needlessly prioritized passenger safety over commercial innovation".

Pretty much says it there along with a rationalization about why the company should ignore any outside experts due to "innovation".

Video contents: An experiment where the vacuum safety valves were removed from an oil tanker railroad car, and a vacuum was placed inside the car, resulting in it crumpling in an implosion. There is no gore or other specific disturbing content

Milliseconds, at most.

If it was structurally compromised, the implosion would be so fast, a combustion event a la what happens in diesel engines would have occurred.

There would be no bodies. There would only be shreds of pressure hull.

The titanium hemispheres may have maintained their shape. There is a slight chance it may have been a pinhole leak, and someone had a second to go "Uh..." before the rest of the structure started giving way.

It is clear that even these "strain gauges and microphones" to detect compromise of the structure were useless, or that the issure ultimately rested on the window in the front.

The main point to keep in mind is that short of finding the two hemispheres in the next day or so, we'll likely not know the full details with regard to the course of events of the unmaking of the vehicle.

The Sea has claimed them, and she is wont to give up her dead. Hubris, met by the cold hard edge of reality, has proven to be an insufficient aegis once again.

May they rest in peace.

Bodies are mostly water, which is not compressible. So not really. But all the voids would have filled very quickly: the sinuses, ears, trachea, and lungs would have collapsed instantly. The bodies would also have been "pasted" against the opposite bulkhead to the failure, as unlike water the air around them would have been very compressible indeed.

> Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.

That's with a nine atmosphere pressure differential. The Titanic is at about 400 atmospheres.

This would happen on the order of milliseconds.

Eg I'd imagine the poor souls on the Titanic next door are not crushed by the pressure, for the same reason.

Or with scuba diving, deep scuba is complicated and dangerous for many reasons, but the pressure compressing the body is not one of them.

It was a cheap third party Xbox controller. i.e. it's the spare controller you made your friend use when he came over to play Halo 2 that one time.

Nobody thought the gamepad was the actual cause of failure. They thought the gamepad was funny in the context of Stockton Rush cutting corners.

it’s strange on its face to use a game controller when we’ve all spilled soda or water on one and watched it become useless and they’re taking this into… the ocean… and just to add insult to injury, playing on offbrand controllers always irritated me so to see them cut even further was super strange.

more than anything it is that combined with the stuff he bragged about buying from camper world—just a sign of strange corner cutting indicating their was likely more that we weren’t seeing.

Two reasons, I think. First, the (apparent) shoddiness of a control mechanism is easily understood, whereas the reasons why carbon fiber makes a poor choice for a pressure hull are more difficult to understand. Consequently, the use of a game controller is a more salient example of a company cutting corners than their choice of material in the pressure hull. (This is somewhat undermined by the fact that a game controller actually isn't necessarily a problem--Ars Technica ended up running articles on consecutive days with the first one being a tee-hee-they're-using-a-game-controller article and the second one being a why-the-military-uses-game-controllers article.)

The second reason may be that some people would rather focus on the potential failure that admits a possibility that the inhabitants are alive instead of potential the failure that guaranteed their death before the search started.

That's all true, but the use of the Logitech game controller and and other consumer-grade electronics rightfully drew scorn of its own.

I deal with automotive electronics, which is less rigorous than aerospace and/or military applications, never mind deep sea operation. Even so, in the automotive space, there is considerable attention paid to making the housings, cables and the electronics themselves robust with regards to the environmental conditions. Heat, cold, moisture, dirt, vibration, salt, etc. The idea of using non-redundant, consumer grade electronics to control a deep sea vessel is ridiculous. Just being regularly exposed to salty air could induce corrosion in critical components.

An accident is when something unexpectedly goes wrong. This end result was baked into the design and it was merely a question of how many times you could cycle that hull before it would implode, not if it would. Death lottery.
