A crew member throws a wreath overboard during a memorial service, marking the 100th year anniversary of the Titanic disaster, aboard the MS Balmoral Titanic memorial cruise ship, at the wreck site in the North Atlantic Ocean, early Sunday, April 15, 2012. Aboard the Balmoral, a cruise ship taking history buffs and descendants of Titanic victims on the route of the doomed voyage, passengers and crew will hold two ceremonies at the site of the disaster, 400 miles (640 kilometers) off the coast of Newfoundland - one marking the time when the ship hit the iceberg, the other the moment it sank below the waves. At 2:20 a.m. ship's time on Sunday - 0547 GMT or 12:47 a.m. EDT - a minister will lead prayers, floral wreaths will be thrown into the sea and a shipboard band, which has been entertaining guests in the evenings during the cruise, will play "Nearer My God To Thee," the tune the Titanic's band kept up as the vessel went down.(AP Photo/Lefteris Pitarakis)
