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.
This quote stands out specifically because he chose to use a Logitech Bluetooth game controller to pilot the sub. All around madness.
