A deep-ocean historian and shipwreck analyst who dived with James Cameron for the Titanic has issued a chilling warning about the tourist submersible which has gone missing in the Atlantic.
Parks Stephenson worked as a technical advisor to James Cameron for Titanic, carrying out extensive interior exploration inside the wreck. He first dived the Titanic wreck with director James Cameron in 2005, and has been to the wreck site five times since then and twice to the wreck of the Titanic's sister ship, Britannic.
After a submersible used to take tourists to view the wreck of the Titanic went missing the Atlantic Ocean, he issued a stark warning about the severity of the loss of communication.
