      I’m no expert but I think we’re looking at parts of the vehicle which were outside the pressure hull. Those parts would not have been subjected to such extreme forces when the hull failed.

      Most bits of a DSV are actually outside of the pressure hull, just look at the designs of Trieste or Limiting Factor. This is to maximize the space available to human passengers inside the relatively small (and very expensive to construct) hull.

      Also little cleaner than what I was expecting granted it’s probably been cleaned up from wild life and the recovery crew but still I was expecting a little bit of blood like I’m not even trying to be a gore loving weirdo I just know that humans are basically balloons full of blood and implosions are really violent especially at that depth this sub went to

        Keep in mind that the balloon of blood in this case is being crushed by water. Any blood wouldn’t have hit the walls as much as diluted in many gallons of water. Without a chance to deposit and dry, blood doesn’t really “paint” things.

        Now I’m generally curious now that can see the it. That thing is pretty much like a crushed soda can. What really happens to the bodies tho? At depth, The tube goes poof and implodes in milliseconds but do the bodies implode too or they just crushed in the pop can.

          They would’ve been instantaneously turned to ash. The vessel temperature at the time of breach would be about 5000 celsius. About the temperature of the sun. Whatever was left would be oozed out the cracks like play-doh

          The bodies can’t implode; the lungs can/will collapse but that is pretty much the least of the issues. Even if the bodies aren’t pulverized by the collapsing sub, the water will hit like a hammer traveling at supersonic speeds. So probably a combination of rendering into mincemeat, dismemberment, and scattering of the human remains would result from such an implosion. A destruction on par with being hit by a bomb at ground zero.

          That depends on what happened. If the whole structure collapsed instantly, they are probably crushed by debris and a shockwave. But if there was a “leak” and the pressure equalized without complete destruction maybe the lungs are compressed, ribs broken and eardrums torn. All depending on the speed of equalization. Maybe also bones break (because water is compressible) but the bag of meat and blood should remain intact. So finding a body would help to reconstruct what happened. But I doubt they will find one before hungry animals do.

            Not possible for anything but immediate implosion at those depths. Even a microscopic leak would instantly turn into a beach.

          I read that from the compression the air ignites so they probably burnt to ashes in milliseconds.
          But I might got it wrong.

            I don’t know if that kind of temperature lasts more than microseconds, so that might not be enough time for much combustion to happen.

            In any case, the forces, IIRC, from a 300 atm pressure differential would mash the people to goo in the blink of an eye. Like being inside an exploding bomb. Except exploding in. They’re fish food.

            EDIT: There are reports that the Coast Guard recovered “presumed human remains”.

            What could possibly be left of them after that implosion?

        Well, they moved it through 3500 meters of water in the process of retrieving it. That’s gonna be the equivalent of a full wash cycle, albeit in seawater.

      I’m just reading and watching news interviews with experts so I’m just armchairing here, but It looks like the parts that survived are titanium bits that is what certified submersibles also use, except they usually is spherical in shape. I imagine the tube bit that’s made with carbon fibre where they housed the passengers is the bit that is so torn up that it’s unrecoverable

      The pieces shown in these photos are the metal parts. The bit that was most likely to break up was the cylindrical carbon fibre hull, and there are no pieces of that in evidence here. The acrylic window is also missing from the front piece.

          OceanGate CEO Stockton Rush says the company had been evaluating the potential of using a carbon fiber composite hull since 2010, primarily because it permits creation of a pressure vessel that is naturally buoyant and, therefore, would enable OceanGate to forgo the use — and the significant expense — of syntactic foam on its exterior. So, for Cyclops 2 OceanGate decided to avoid the metallic hull altogether and began a search for a manufacturer that could help it develop a composite hull.

          Once again the motive for the choice of carbon fibre seems to have been its relative cheapness.
