http://www.youtube.com/watch?v=5RIn0OwdHXYThe RMS Olympic was the first ship of the Olympic-Class RMS (Olympic, Titanic, Britannic). They were build between 1908 to 1914. Olympic and Titanic were the first one to launch and saw their self, Britannic saw the Olympic also.
RMS Olympic proved in the World War 1 that she will see that she would overcome the tragedy of her sistership of Titanic, and I think the sinking of Britannic was too much for the Olympic. Olympic did a good job, and destroyed an Germany Submarine.
RMS Olympic turned in service again by 1920. An new sister joined her, the 56,000 GRT Majestic. They will both sail to their final fate. RMS Olympic would have been saved in 1935, but nobody did care about the historic vessels. Only Majestic was saved, Mauretania and Olympic weren't.
The steamships should be rebuild, as they were and let them sail with the cruise-ships together!!
