At least vaporizing yourself in an experimental carbon fiber tube is a pretty unique and interesting way to go. [/quote]

Vaporizing?

That implies heat. This sub was 10000 ft underwater in near freezing temperatures. Good luck vaporizing anything.

You must’ve studied science at trump university. [/quote]

The immense pressure of water entering the capsule would pulverize any living matter in the sub. We are talking surface of the sun temps. Gone. Nothing left. Literally E=mC^2[/quote]

Maybe a little PV=nRT too. [/quote]

A lot of T[/quote]

Exponentially increasing V = exponentially increasing T

Typo: 
Exponentially increasing [u]P[/u] = exponentially increasing T

Followed by...
decreasing V = decreasing T

It’s gruesome, but the Byford dolphin incident is as close as I can think of known outcome in somewhat similar circumstances. It was a decompressive, rather than a compressive incident, and it was from 9 atm to 1 atm. Other vessels have imploded, like the uss thresher, but no one survived and there is a lot of uncertainty about what really happened. Don’t read about Byford dolphin if you are at all squeamish. The titan sub imploded with an external pressure of 500 atm to 1 atm. It’s hard to wrap your mind around a reaction that happens magnitudes faster than human reaction. [/quote]
My God. How did you come to know about this incident?[/quote]

I took an ethics in engineering course as part of my mech engineering curriculum for undergrad. I posted earlier (like 30 pages ago) that we studied classic engineering mistakes. The Byford dolphin was not one that we spent a lot of time on, but was mentioned because it was just so awful. The design for the chambers was bad, prone to human error. The titan sub will definitely make the list of unethical engineering mistakes that cost lives. [/quote]

Really fascinating. Would love to know what institution this was but realize it may be too close to identifying. Thanks for the knowledge![/quote]

DP. In my engineering curriculum these types of failure were covered during a risk analysis course. [/quote]

Another DP. Same at my engineering school.  [/quote]
