    … How do you propose to emergency exit that sub at 1000 meters depth?

    I’d say the bigger issue is that he used a carbon fibre body, a material which has great tensile Strength but sucks for this.

    They way bigger issue than that is that he glued the metal rear section to the carbon fiber body. Both materials expand and contract differently under pressure, which is not what you want at 3 kilometer deep pressures, especially with multiple descends and ascends. That glue could never keep those materials together, that alone was a disaster waiting to happen

      And people usually consider this when building a barn, doing plumbing in a house. The scariest thing is how can someone who doesn’t understand this make a submarine. Real Crassus vibes.

      The problem was that if they surfaced away from the support vessel, there was no way to open it to get fresh air. So you could still run out of oxygen and die while floating around on the surface waiting to be found.

        Yeah that sounds like less of an issue to me, honestly. That support vessel van be there quick enough, send in airplanes, whatever. You can make a more intricate inside and outside locking mechanism but that’ll make your entire submarine a whole lot more expensive
