In my personal opinion, the story of Titanic has held people's imagination ever since it happened because there are so many unanswered questions as to why it happened, there are so many people involved in the tragedy, and so many lives were lost or ruined completely, plus of course it was at the time the greatest maritime disaster to have ever happened.
Plus, of course, the ship was deemed to be unsinkable and was lost on her maiden voyage.
I've been fascinated by the whole story ever since I read a book about it when I was still at school, I've collected several Titanic related items over the years, and built two models of the ship...one a static display and one radio controlled.
The whole Titanic saga still interests me immensely after...what, nearly fifty years now, and probably will do for the remainder of my days.
