Why can't they take the Titanic out of the water?
Why can't they take the Titanic out of the water? There are fears that during retrieval, the Titanic wreck would disintegrate into pieces, making it impossible to have something concrete by the time the remains reach the sea surface. There are documented reports that metal-eating bacteria has already consumed most of Titanic's wreckage.
Can Titanic happen again?
Those changes, along with the advent of superior technologies for navigation and communication, have made the seas much safer since 1912. As such, it is unlikely that the specific circumstances leading to the sinking of the Titanic will recur. But the ocean remains an unpredictable place, fraught with hazards.
What if the Titanic sank in warm water?
Had the Titanic sank in warm water, most of those in the water would have survived. Almost all had life jackets on, and the lifeboat passengers were rescued only a couple of hours after the ship sank. Passengers of sunken cruise ships can't survive indefinitely though unless the water is tropical.
