How fast did the people in it die?
Of course once the sub filled with water they would die instantly because it would reach insane pressures (300-400 ATM or 5800 PSI)
Less than 4 milliseconds. They didn’t feel a thing.
To add context here, it takes your brain somewhere around 100ms to detect and then another 250 to process pain. So 4ms is not only fast, it’s absurdly fast.
To get a sense of how fast it is, go ahead and stub your toe, the time it took to feel it is 100 times longer.
How did you get this number?
Do you think they died from the water rushing in and hitting them unconscious?
They died by being crushed with enough pressure such that the air inside the sub ignited ie compressed so much it essentially exploded. Death was instant.
I know a diesel engine works off compression, but it has a fuel. All fires must have oxygen, fuel, and heat. What fuel would they have in the titan to ignite?
Water contains oxygen. With enough heat that oxygen becomes free.
