Hopefully, examination of the wreckage will yield valuable information about the cause of the failure and help future designs of deep-sea submersibles.
We already know how to build submersibles. Engineers told the CEO that this submersible was not built to spec and not safe. He fired them.
Sure we do but there's always something to be learned from a failure. This sub was unique in it's design and while that design ultimately failed, the knowledge gained from the failure could potentially lead to an improved design that maintains some of the benefits such as low cost and high occupancy.
Also when carbon fibre is used on other applications such as in planes and such. There is always something to be learned about failure modes which can be used to make future applications safer.
For instance, in this case where exactly did the failure point happen? Was it at at the bonding area, one of the end caps, or in the middle of the tube, etc.
Normally I’d agree with you, but we already know that carbon fiber is weaker in compression than in tension and that you really shouldn’t attach it to titanium either, due to their differences in malleability.
