    Based on the simulations I’ve seen, yeah. I’m sure there were plenty of panic in the sub and during the anaphylaxis, but I believe once the sub failed, there was less than a second between in first physical sensation to the complete disorganization of the nervous system, rendering the sub death quite painless. With anaphlaxis, even a sudden, sever attack, there will be several minutes of (at least) muscle strain as your diaphragm desperately tries to pull in more oxygen, and also general pain as your tissues squeeze against one another as they expand and nerve cells die.

    I can and have accepted death; I’m too old to believe radical life extension will save me. But, many deaths are incredibly painful. If I have a choice on how to go out, inert gas asphyxiation seems best, but some sort of rapid disorganization isn’t too bad. Anaphylactic shock seems worse.

      I read it happened over one millisecond. Not enough for the nervous system to even register something was happening.

        The final crush, yes, but they were having troubles on the descent. They dropped weights and were attempting an emergency ascent, but the sub wasn’t raising as fast as it should’ve. Meaning, the sub was either taking on water or shrinking in size (minor hull failure/deformation) loooong before the CF popped off the dome and poof.

          If they weren’t ascending at the right speed it was a motor failure. The hull was fiberglass it can’t deform, it can get cracks and hold or fail. The scary stuff leading up to failure would be loud sounds coming from the hull.

          Yea, I remember the final text said something like “dropped two weights”

      Nah. From hull breach to complete obliteration would be measured in fractions of a second. There’s NO possibility there was some kind of “small leak” leading to anaphalaxis. The instant one large molecule could pass the seal… goodbye smash-aroonie.

        The “anaphalaxis” I was talking about was the alternative to the sub crush, and what happened to the billionaire that is the subject of the article, so I think you might have misunderstood me?

        Nope. The titan sub was having trouble. They dropped weights and were attempting to make an emergency ascent, but it wasn’t rising fast. Meaning, the density of the sub was increasing. Some people are saying leak, others say water egress between CF layers and the hull failing, meaning contraction in the middle, like squishing a tube (see the simulations for how the static deformation would look like).

        Sure, the complete failure was over in milliseconds, but not the experience of being an experimental test passenger on a rich moron’s death trap!

        They were comparing anaphylaxis to death in the sub, not saying it was from a leak on the sub.
