Nor has it been seriously checked for stress from repeat trips. This is what makes me think it got crushed on the way down. Carbon fibre is essentially a brittle laminate, so repeated stresses could cause small cracks between layers, eventually resulting in a catastrophic failure.

Thanks, I didn't think it had been down that deep before. I was reading that the company that manufactured the porthole would only certify it to 1300m.
