What is the fascination with the Titanic

Am sat here, getting ready to take the puppy for a walk, watching yet another program about the Titanic. It will be 100 years in April since the Titanic set sail. And yet, with all these films, documentaries and actual research projects there still is no definitive conclusion to the cause of the disaster . The result goes without saying. Less thinking and back to the real world of puppy walking in the clear cold of a January winters dayemail
