One of my favorite YouTube channels reviewed the titan sub disaster and the results were not pretty.

There were some experiments with carbon fiber at depths 20 years ago that were very promising, and there are supposedly teams working now to perfect the binding agents (epoxies) and solve the delamination problems. Since this relates to all manner of deep-sea industries (fiber cables and oil/gas pipelines), there's money behind it and a will to create reliable long-term solutions. Had this company done the appropriate testing, I'm sure they would still be years away from manned missions. In 10-15 years, we will probably have perfectly good carbon fiber pressure vessels suitable for deep sea exploration.

I think The Onion jumped the shark with the last bit. It was funny until they mentioned Children.

More and more these past few days, I've been thinking why wasn't the potential risks adequately understood by the engineers? Like Will said, it's elementary knowledge that is taught to all engineers in college very early. There's nothing wrong with trying it, and it may well prove to be safe, but it was ground breaking and so should've had a lot more (years) of research and development behind it. It's because of incidents like these in the past that the aerospace world takes a cautious approach to fielding new technology. All one has to look at is the use of composites for primary structure in aircraft, which comes on the heels of decades of research and development in the use of composites in secondary or non-structural applications.

There is a website called composites world which item after item on OceanGate and their technology and tests. It reads mostly like rehash of press releases but with 20/20 hindsight it is so creepy to read.
