"Titanic director and submersible expert James Cameron said he predicted Titan's implosion days before the debris from the missing submersible was found, calling the search a 'prolonged nightmarish charade'. Mr Cameron, who has visited the world's most famous seawreck 30 times, said the tragedy this week has parallels with the the Titanic disaster, where the captain repeatedly ignored warnings about an incoming iceberg but carried on at top speed.
A remote operated submarine from a Canadian ship found debris on the ocean floor. But search and rescue officials say the men likely died on Sunday - before military planes using sonar buoys detected what they thought could have been SOS 'banging' sounds in the water. The US Navy said they heard a sound consistent with an implosion when communications were lost around two hours after they dived. The Navy passed on that information to the Coast Guard, an insider said."
