I always wanted to post a blog about this story but kept forgetting.
There is significant evidence that the Titanic was a badly damaged Olympic that was rammed into an iceberg deliberately to collect the insurance money. They planned to take the passengers off on a nearby steamer but it never showed.
You may have wondered like me how the ship was smashed into an iceberg that could be seen from thirty miles away. That part of the story was always a bit dodgy sounding.
Sorry if this ruins the James Cameron fantasy for you.
