Strathclyde University student Suleman Dawood felt "terrified" before embarking on a trip to the Titanic shipwreck - with his dad Shahzada and three others - his aunt has revealed.
The 19-year-old was on the Titan submersible when it went into the ocean off the coast of Newfoundland, in Canada, on Sunday, and never returned.
Others on board included his dad Shahzada, 48, Stockton Rush, the chief executive and founder of OceanGate Expeditions, Paul-Henri Nargeolet and billionaire pilot Hamish Harding.
