“The more you know”
The Boeing 787 is made from carbon fiber. The airframe is pressured for obvious reasons. Just 9 psi.
The sub was the reverse pressure from the outside in. 5000 psi! And that owner was not an engineer. He just made up his design on a piece of paper.
NO he was an engineer. He had a degree in aerospace engineering. As I said, he knew better.
He as an idiot. He’s even on record as saying “they say you don’t use carbon fiber, well I did”.
