And, just for context, Challenger Deep is nearly 3x as deep as the wreck of the Titanic.

It’s also worth mentioning he was the first ever person to reach it solo.

Off topic, but damn! Richard Garriott is on that list!! I love the guy, man I remember playing Tabula Rasa all those years ago... And kind of crazy now that I know Gabe Newell own one of the very few subs that can do this kind of depth... And that the Titan was piloted with a gaming controller...

Man I completely forgot Lord British did this.

In the system design of a submarine? Really? How many has he designed?

He was heavily involved in the design and development of Deepsea Challenger (along with Ron Allum, the lead engineer).

One. That won a contest. Is it enough, or should he have designed multiple?

"Heavily involved" means what?

I would like to know details on the design and why specifically it's bad. Saying "it's poorly designed because Cameron says so" is not good enough. There is more detail in the YouTube videos from actual marine engineers on why specifically a carbon fiber hull is bad, why acoustic testing is insufficient, etc. They're not known and not relatable to the public yet more informative. That's my point.
