#1 Isn't that what happened to the SpecOps guy who stole the H-bomb in The Abyss?

#3 Computer modelers could illustrate how a Titan Sub could give birth.

#4 I think the fictitious court cases cited by an AI recently tell you all you need to know about "computer models."

#5 Whatever broke first at this point is actually irrelevant. The sub had what is refered to as 'single failure mode'.
Any one fault would destroy it. There was nothing remotely resembling a backup, on anything. Any one failure, and it's all over.

#6 All of this speculation on how precisely that submersible imploded is becoming downright ghoulish!

#7 'single failure mode'

It's nearly impossible to redundantize (awful usage, I know) a system against catastrophic failure.

#8 #6 All of this speculation on how precisely that submersible imploded is becoming downright ghoulish!

The views of an engineer in speculating how this particular submersible collapsed, including computer modeling, is not ghoulish, IMO.

#10 Seriuosly, did we have to have bug eyes?

#11 The problems of redundancy to prevent catastophic failure have been well studied for decades. Look at refineries. They've been dealing with similiar pressure and thermal issues for years, and largely successful at it.
The peak fault occurence is usually in transition, i.e. start up or shutdown. Things are quite stable at each end of the curve, but it gets crazy in the middle. Almost like an inverse bell curve. Generally because the material it's made out of reacts to stress unevenly.

#12 ^ I meant once the catastrophic failure is under way. Horse > barn door.
