Anybody for a cruise in the Mediterranean? The capsizing of the massive luxury liner, the Costa Concordia (twice the size of the ill-fated Titanic), has galvanized the attention of the gaping world. According to some reports a mere 300 feet from shore, this luxurious $450 million floating city of 4200 passengers and crew struck a rocky outcropping in the reef off the island of Giglio, gashed a fatal hole in its hull, rolled to one side and began to sink. Only the snagged reef kept the vessel from sinking to the seabed 160 feet below.
