The Greece tragedy is lacking the irony and hubris of this.
I mean, it's a tourist submersible that was aiming to bring billionaires to view the Titanic wreckage and it likely got wrecked itself. And they named the submersible Titan.
The sub's company OceanGate was dinged by a former employee for all sorts of safety issues and they fired and sued him. There are also lots of choice quotes from the CEO (who happens to be on the vessel) about moving fast and breaking things, and regulations stifling innovation. So there's some possible karma involved.
