The main support ship of the Titan submersible has returned to a Canadian harbour following the deep-sea vessel’s fatal implosion.

Flags on board the Polar Prince were at half-mast as it arrived at the port in St John’s in Newfoundland on Saturday morning after four passengers and the pilot of Titan were killed in the incident.
