Without any doubt the Titanic sinking is the worst maritime disaster.Although its builders considerd it unsinkable,in less than three hours was under the frozen waters.But the greatest loss was that of human beings.Only little more than 700 out of about2200 survived in that unhospitable environment.In july 1986 US. researchers sent a submersible to explore the wreck.The next year they held an exhibition with the jewels and other things from the sunken ship.
