Titanic-The Last Secrets

This was recent episode of the tv series Unearthed on the science channel. It was mostly a rehash but it did have a few interesting items. But I was disapointed with it overall. In it they stated that the first rescue ship arrived 100 minutes after they ship sank and that the bulkheads only went up five "floors" (not decks) so they could have room for the ballroom and other luxury spaces. When it was done it got deleted from my DVR.
