And in this case, the glued joint where the tube and the Titanium Metal Dome meet.

I agree.

A better design (and much more costly) would have been a flanged tube that was then wrapped with carbon fiber mesh.

The flanges would need to be fitted with double o-rings

Ideally the o-rings would have had a tap between them with a pressure sensor to detect leakage from the outside o-ring.

One of the issues with the glued fitting is that it is a single failure joint with no indication of impending failure. When it goes there is no warning.

With the depth this was intended to go to, a triple o-ring flange may be warranted.

But what we are talking about here is very costly. These people were intent on doing exploring on the cheap.

They paid with there lives. Not so cheap I would say.

Triple O-ring, flange with a twist lock and a dozen stud bolts.......................

Yeah, I think water could just pop that joint apart.
