    From what I understand, the sub was basically two heavy titanium ends separated by a tube of carbon fiber. When the hull failed, there would have been a really brief moment where there were 5 people in a small void under tons of pressure pushing in from all sides. I’m wondering more specifically if they were crushed by the titanium ends coming together before they could have been crushed by the pressure itself.

      Just as an fyi on the pressure …

      “The remains of the Titanic are 12,500 feet deep. Experts say the pressure at that depth is between 370-380 bars.” https://www.bbc.com/news/world-us-canada-65934887

      1 bar is equal to 14.7 psi (the pressure of the air around us on our bodies at sea level).

      370-380 bars is equal to 5366-5511 psi … with the added bonus of an auto-ignited explosion of hydrocarbons (that have concentrated in the sub) after the initial implosion … all completed within 1-3 milliseconds.

      The explosion burns everything to ash and dust, which is why only the titanium rear cover and landing gear have been found so far. (The front titanium cover housed the woefully-inadequate “window” and, if it was the failure point, it could be buried in the silt, shattered into pieces or even shot through the Titanic wreck itself … anybody’s guess at this point.)
