Watched several updated and new shows over the last week on Titanic....one last night on History. They took rivets made out of the same materials and put them to the teat under hydraulic testing and they stood up to the test. It was a cool show....where they did high-def sonar of the complete 15 mile debris field in order to capture all the pieces of the puzzle (up to this point, only about 30-50% had been surveyed in no particular order). They did a holographic reconstruction of the break-up of the ship and sinking.
One thing I saw on a Nat-Geo special that explained a lot was info on the water-tight compartment and flooding. I had always thought that the water had went over the "top" from compartment to compartment.......but as one of the scientists on the show said, "water-tight" means sealed separate from each other....water couldn't go over the top of a closed cell. Titanic was designed to stay afloat as long as no more than any four of her water tight chambers flooded. The iceberg ripped into just enough linear hull length to flood five compartments, thus dooming the ship. It was reported that Thomas Andrews, the ship's main designer, went below and surveyed the extent of the damage (right after impact) and reported to the captain that it was going to sink (an account from one of the only surviving engine room workers).
They also said it was a credit to the design of the ship that it stayed upright during the sinking, when practically all ships that size roll over.
Several "authorities" (??) postulated from an entirely different angle than previously thought and said that it was the strength of the ship and its design that led to 700 lived saved instead of all lives lost.
I'm neither agreeing nor disagreeing with the "experts"....merely passing along info from the latest field expeditions and fact gathering jaunts.
