Costa Concordia

Word to the wise: don't get on a cruise ship in a year ending in the number 12. Especially if the captain feels a little too sure of himself.

Earlier this year the world was captivated by images of the Costa Concordia capsized off the Italian coast. The captain allegedly ignored the navigation maps, ran aground and at least 30 people died as a result.

April 12 marks the 100th anniversary of the disaster of the Titanic, which sank about 360 miles from Newfoundland when the famously "unsinkable" ship hit an ice berg. Three hours later, it was an underwater grave two miles below the frigid surface of the North Atlantic.
