“I believe that he's correct, meaning submarine pilot, that it's not the carbon fiber, it's the dissimilar materials connected to it. So, the titanium end caps, and the plexiglass porthole, seven inch thick, What happens is each of them has a different coefficient of compression and expansion. In other words, under pressure, under temperature change, they each expand and contract a little bit differently.”
