It feels like the Titanic is an irony magnet. It's like some cosmic force is still really salty that they called it an "unsinkable ship."
For example, some of the passengers on this missing submarine:
The founder of the submarine company who complained about safety regulations, now lost and trapped in his unsafe vessel.
The Guinness World Record holder for longest time spent traversing the deepest part of the ocean in a single dive will now likely be at the bottom of the ocean forever.
The director of the company who owns the salvage rights to the Titanic. The company that has brought many artifacts to the surface, now likely leaves its director on the ocean floor with the wreckage.
