As the world commemorates the centenary of the Titanic's sinking, thousands of people have taken to the internet to discuss the historic anniversary. A number of tweeters have used the micro-blogging site to confess that they are unaware that the Titanic was a real ship.
RMS Titanic sank in the early hours of 15 April 1912, after being struck by an iceberg during her maiden voyage from Southampton to New York.
But for many of the younger generation, the ship is more familiar from the 1997 film about its demise starring Kate Winslet and Leonardo Di Caprio.
It seems that several fans of the movie failed to grasp that it was based on true story albieit with invented characters.
