Titanic anniversary

Backdropped by the Manhatan skyline, passengers watch as the MS Balmoral Titanic memorial cruise ship, approaches the New York City port, Thursday, April 19, 2012. Exactly 100 years after the Titanic went down, the cruise retraced the ship's voyage, including a visit Sunday, April 15, to the location where it sank, a stop in Halifax and final destination at New York, as of the original intended trip.
