The team behind the deep sea robot which eventually helped locate wreckage from the Titan submersible – following a fatal implosion which killed five people – had been hoping they were on a rescue mission, a company executive has said.

British adventurer Hamish Harding and father and son Shahzada and Suleman Dawood were killed on board the deep-sea vessel, alongside OceanGate Expeditions’ chief executive Stockton Rush and French national Paul-Henri Nargeolet.
