It's not just the billionaire passengers that have brought this story to great attention. They weren't visiting any old wreck - they were visiting the Titanic. The sinking of the Titanic has created its own mystique which attracts headlines to anything associated with it.

Added to that, for a day or two, there was the possibility (remote, admittedly) of an 'International Rescue' style mission to bring the sub to the surface with the clock ticking down on the oxygen supply.

The newspapers and television will print and report anything that gets them more readers and listeners.
