The five crew members on board the missing Titan submersible died in a “catastrophic implosion”, the US Coast Guard has confirmed.

Oceangate Expeditions CEO Stockton Rush, Pakistani businessman Shahzada Dawood and his son Suleman, British billionaire Hamish Harding, and French adventurer Paul-Henri Nargeolet were on a dive to the Titanic shipwreck when the vessel lost communication with its support ship on Sunday 18 June.

A frantic search for the missing submersible unfolded over the course of four days, before news of the “catastrophic implosion” was confirmed on Thursday.
