would they be vaporized or instantly compacted? my morbid curiosity kind of wants to see what would happen to a body under such insane pressure conditions.

As I understand it: the pressure vessel was full of air, and at the moment it failed, that air-filled space became the equivalent of the cylinder of a 2-stroke engine, instantly heating as the air compressed.

  Correct. Except it is heated to a much, much higher temperature.

  You probably meant diesel engine. The compression pressure of those is around 300-500psi, and that's sufficient to heat the air to a few hundred degrees and ignite the injected fuel. For comparison, what happened in this sub was 10x that pressure. (Yes, 2-stroke diesels also exist, and sound absolutely amazing.)

    Much higher than that. The external pressure was ~6000psi, but water has inertia. The peak pressure as the bubble imploded was many orders of magnitude higher than that.

    Ignoring inertia (the water hammer effect), the air would reach 38,000 F, four times the temperature on the surface of the sun.

You're in luck, the Mythbusters tried this: https://www.youtube.com/watch?v=LEY3fN4N3D8 https://www.youtube.com/watch?v=LEY3fN4N3D8

  ... and that was like, a couple hundred feet. The Titanic is at 12,500 feet. An unfathomable amount of pressure.

    12500 ft is 2083.33 fathoms.

      This reply is leagues ahead. What other nautical-related terms are a part of common speech?

        I'm tying myself in knots trying to think of one.

        These puns are so deep

        Those are two different meaning of the same word though, and the one in your usage is not specifically nautical, so I’m not sure it qualifies. But a good pun nonetheless.
