A group of 1,309 passengers boarded the MS Balmoral on Sunday, in Southampton, England, on a voyage to retrace (重走) the path of the Titanic. The Titanic was the biggest ship in the world when it sailed on its ill-fated first voyage on April 10, 1912. Of the 2,227 passengers and crew aboard, more than l,500 died. The ship, which was headed for New York City, carried the rich and famous on its first voyage. It also carried immigrants who were seeking a better life in America.

Relatives of people who sailed on the Titanic, historians, authors and people fascinated by the story of the unsinkable ship were on the Balmoral. They wanted to remember the Titanic and those who died on her first and last voyage.

The Balmoral was following Titanic’s original route from Southampton. First, the modern-day cruise liner docked (进港) in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stopped in Cobh, Ireland, the Titanic’s last port of call before sailing to New York.

The Balmoral then sailed the North Atlantic Ocean to the location where the Titanic hit an iceberg. On Sunday, April 15, at 2:20 a.m. — the time the Titanic went down - passengers and crew held a memorial service. The next two days were spent in Halifax, Canada, where many victims of the Titanic are buried. Then, the Balmoral reached its final destination in New York City, where the Titanic was supposed to dock — but never did.

So far, several teams of divers have explored the site. They have recovered items such as dishes and silverware and put them on public display. And the Titanic and its passengers and crew have been remembered in books, movies and TV programs. But there’s a much more important contribution that the Titanic has given us. After she sank, lawmakers and ship builders made ships safer. It took a terrible tragedy to make ship travel safer for all.
