The Titanic just prior to being launched into the River Lagan for towing to a fitting-out berth where her engines, funnels and interiors would be installed, May 31, 1911. The Titanic was considered unsinkable but foundered in frigid Atlantic waters off Newfoundland after striking an iceberg. About 700 passengers survived in lifeboats, but some 1,500 perished in the sinking. [Photo/Agencies]
