205 Million Pascals, according to source quoted below.

1 Pascal = 0.0000098 atmospheres

205 Million Pascals = 205000000*0.0000098 = 2009 atmospheres

2009 atmospheres is equivalent to water pressure at roughly 20 Kms.

Note: this is compressive strength, which is far higher than e.g
resistance to breaking. So according to this source (and others),
the femur will not "liquify" at Titanic depth -- that will begin to
happen only at five times that depth.

Ultimate Strength of the Femur
The maximum stress that bone, or any other material, can experience before the material begins fracture or rupture
is called the ultimate strength. Notice that material strength is defined in terms of stress, not force, so that we
are analyzing the material itself, without including the effect of how much material is present. For some materials
the ultimate strength is different when the stress is acting to crush the material (compression) versus when the
forces are acting to stretch the material under tension, so we often refer to ultimate tensile strength or ultimate
compressive strength. For example, the ultimate compressive strength for human femur bone is measured to be 205 MPa
(205 Million Pascals) under compression along its length.

You're not just dealing with pressure on the bones though are you, there's
also the rapid collapse of the submarine around the bones and the bones
would be hit from different directions all at the same time.

I'm sure you would find body parts but they'd effectively have been next
to an explosion.

No, no, no. So long as you equalise the pressure you can have one of the twin towers collapse on your head and still walk away with barely a scratch.

Unfortunately the fly I splattered today forgot to equalise the pressure.

As did the neighbours cat when I dropped a pallet of bricks on it.

The Titanic hasn't imploded and I also put a steel rebar in a vice which couldn't even dent it. It stands to reason it would be the same if you slapped your cock in a vice and tightened it up.

Whatever you do, don't Google for the aftermath of people jumping out of tower block. Seriously. And never get suckered by trolls.

Yes, I was specifically referring to claims that "bones would be 'liquefied'
or 'disintegrated' by the pressure" etc

Difficult to tell exactly what happens in such situations, but indeed, my
point was that body parts will still be found.

But body parts will still be found. That was the point. By the way,
it's an interesting exercise to compare the pressure in both cases;
go for it.

> And never get suckered by trolls.

Indeed. Like trolls who cannot understand the most basic mathematics,
and rant about "canceling infinities", or claim that the notion of
infinity is "mental masturbation", etc. Lucky those chaps Hardy, Dirac,
Hawking etc. are dead! The news would have devastated them.

But back to the topic: you wrote

"The question remains; what random or natural noises could have caused
repetitive banging for three minutes every half hour for hours on end
which was perceived to be 'proof of life' signalling by experts in
such things"

Can you present a source to the "banging" being "repetitive for three
minutes every half hour"?
