OceanGate CEO faces criticism over Titan submersible design and safety.

Stockton Rush, the CEO of OceanGate, criticized certifying agencies for submersibles, calling their rules and regulations "over-the-top." Rush's submersible, the Titan, suffered a catastrophic implosion on its journey to see the Titanic shipwreck, with all five passengers presumed lost. The Titan had a carbon fiber design that was never certified, despite warnings from experts. Rush had broken rules to make the submersible, including using carbon fiber and titanium, which are not recommended. Critics say that steering away from sound engineering principles has a terrible price, and it should never be allowed to happen again.
