RushAccording to Weissmann, Rush boasted about how he had bought carbon fibre for the sub “at a big discount” because “it was past its shelf life use in airplanes”.
He told the Washington Post: “I responded right away, saying, 'Don’t you have any concerns about that?’ “He was very dismissive and said: 'No, it’s perfectly fine. Having all these certifications for airplanes is one thing, but the carbon fibre was perfectly sound.'" Experts have previously said how carbon fibre was a poor choice of material for the sub but using materials past their expiry date could have made the sub even more susceptible to problems, some have claimed.
Experts have also suggested that water could have seeped into the space where the carbon fibre met pieces of titanium.Most read in The Sun
