The Titanic had two sister ships, the Britannic and the Olympic. There was a woman called Violet Jessop, a nurse and a cruise liner stewardess that worked on all three. The Olympic crashed into a warship whilst leaving harbor but was able to make it back. She was on the Titanic as it sank and is referenced in the Titanic film, a stewardess that was told to set an example to the non english speaking passengers as the ship sank. She looked after a baby on lifeboat 16 until being rescued by the Carpathia the next day. It's not known what exactly caused the sinking of the Britannic but the lifeboats hit the water too early. As the ship sank, the rear listed up and a number of the lifeboats were sucked into the propellers. Violet had to jump out of the lifeboat she was in and sustained a serious head injury, but survived. She was on board for all three incidents in the space of 5 years. She went back to continue to work at sea for another thirty years before retiring in 1950. She died of Heart failure in 71.
