The NYTimes reports that a combination of historical and forensic/archaeological investigation suggests that the Titanic sank much faster, dooming hundreds of people, because lower-grade iron rivets were used in the bow of the ship. Disputed by descendants of those involved in the construction, this line of research was only possible due to examination of rivets and plates found at the wreck site, and was then put in context by examining the manufacturing company's records and board meeting minutes.
Like others I know, I went through a "Titanic" phase in my youth. I remember being tremendously excited when the first evidence of the wreck was found over twenty years ago. So I am particularly intrigued by this development.
