Family of Explorer Who Died in Titan Sub Files Lawsuit

A chilling new claim about the five passengers who lost their lives on their way to see the wreck of the Titanic has emerged. The Titan sub was 90 minutes into the dive when something went wrong. The vehicle imploded, killing everyone on board. One of them was Paul-Henri Nargeolet. A lawsuit by his estate alleges they would have felt "terror and mental anguish" as death loomed. The lawsuit also says Titan began dropping weights in an apparent effort to return to the surface but it didn't work.
