Somewhat of a quote from ghosts of the abyss:

'The titanic story is very personal to each person that hear's it, this massive ship in the middle of the atlantic, all these people, only half can survive'. In the words of james cameron 'you couldnt have written it better', tragic though that it actually did.

Loss of Titanic was a collection of mistakes and error's (to say it was just bad luck isnt really a strong argument). The accident that Olympic suffered only added to the white star lines ego that their ship was unsinkable, as such leading the crew and it's passengers into a false sence of security. This therefor I suppose you could argue making them less 'on the ball' as it where.

The 1997 film sky rocketed the ships popularity and the publics thrist for more about it. I myself when i saw the movie at age 7 was very taken in by the story (more so the ship and the people rather than jack and rose) and since then iv kept up a healthy intrest.

The whole thing about each persons story, the time, the other ships it makes for a lot of reading and learning :)
