The search for a submarine carrying five people that went missing on its way to view the wreckage of the Titanic continues on Wednesday, with a growing number of ships and aircraft joining the US-Canadian rescue effort.
The Titan sub, which is operated by OceanGate Expeditions and has taken fee-paying customers on tours of the disintegrating remains of the doomed ocean liner since 2021, lost contact with its tracking ship, the Polar Prince, on Sunday afternoon, sparking a desperate race to retrieve it before the air supply inside is exhausted.
