Film director James Cameron has expertise in designing and testing these submersibles, and he has many criticisms of the design of the sub that imploded, and of the hubris of the CEO who ignored repeated safety warnings from the diving community. He also mentions that the sub seems to have been attempting to resurface when it imploded, suggesting that they were aware the hull was starting to fail.
Oh, way dumber than the Titanic. Titanic was one of the safest ships of its era. It could withstand 4 of its watertight compartments being completely flooded and stay afloat. The issue was that they grazed the iceberg in such a way that 6 compartments ended up being compromised. Despite that, it still stayed afloat for 2 hours. Look how much crap its sister ship the Olympic went through and stayed afloat.
This stupid thing was a disaster waiting to happen.
It also would’ve stayed up a lot longer if the watertight compartments had gone all the way up, so water couldn’t have continued filling ones further aft. It still had more compromised than it could withstand, but it may have been able to remain afloat long enough for the Carpathia to arrive for rescue
