could've built the Titan
Nahh. Too expensive and too heavy and not doable. The hull must have been built with a steel alloy or at least titanium. My guess without doing the math is a hull 7+ inches thick, seamless with no windows. When I read carbon fiber??????!!!!!!!!!! I could not believe it. Without doing much thinking who in his right mind would go to the bottom of the ocean in carbon fiber. Don’t these billionaires have google?
