Very good observation, Charlie. The current "cruise culture" is based upon the notion that modern ships fulfill the "unsinkable" myth that the Titanic (and the Andrea Doria) failed to live up to.

Concordia was, by any estimation, a "mega ship" and one that was supposed to be up to anything the sea (or sea-bottom) could throw at it.

Yet here we have it.

Her bottom ripped open, sunk, and passengers dead.

Worse than Titanic in the sense that her passengers were out for a lark, as opposed to having any "business" reason to be aboard.
