was the lusitania the sister ship of the titanic
RMS Lusitania RMS Lusitania was a British ocean liner that a German submarine sank in World War I, causing a major diplomatic uproar. The ship was a holder of the Blue Riband, and briefly the world's largest passenger ship until the completion of her sister ship Mauretania. The Cunard Line launched Lusitania in 1906, at a time of fierce competition for the North Atlantic trade. She made a total of 202 trans-Atlantic crossings.[3]
RMS Titanic After leaving Southampton on 10 April 1912, Titanic called at Cherbourg in France and Queenstown (now Cobh) in Ireland before heading west to New York.[5] On 14 April, four days into the crossing and about 375 miles (600 km) south of Newfoundland, she hit an iceberg at 11:40 p.m. ship's time. The collision caused the ship's hull plates to buckle inwards along her starboard (right) side and opened five of her sixteen watertight compartments to the sea; she could only survive four flooding. Meanwhile, passengers and some crew members were evacuated in lifeboats, many of which were launched only partially loaded. A disproportionate number of men were left aboard because of a "women and children first" protocol for loading lifeboats.[6] At 2:20 a.m., she broke apart and foundered—with well over one thousand people still aboard. Just under two hours after the Titanic sank, the Cunard liner RMS Carpathia arrived at the scene, where she brought aboard an estimated 705 survivors.
