Three of the crew members on board the submersible exploring the shipwreck of the Titanic which has disappeared in the Atlantic have been identified, and one even issued a chilling warning about deep-sea exploration previously.
The three identified so far are said to include billionaire British explorer Hamish Harding, French submersible pilot Paul-Henry Nargeolet and CEO of OceanGate Expeditions Stockton Rush.
Hamish Harding's stepson confirmed on Facebook that his stepfather, 58, was on board the Titanic submersible when it went missing, asking for "thoughts and prayers".
