In this photo taken Sunday, April 8, 2012, passengers from the United States, names not given, wearing period costumes, look out from aboard the MS Balmoral Titanic memorial cruise ship as it sails from Southampton, England. A cruise carrying relatives of some of the more than 1,500 people who died aboard the Titanic nearly 100 years ago set sail from England on Sunday to retrace the ship's voyage, including a visit to the location where it sank.
