Watch: View of harbour where Titanic tourist submarine departed as search for missing vessel continues

Watch a view of St. John’s Harbor, in Newfoundland, Canada, where the missing Titan submarine departed on Sunday 18 June before losing contact with surface crews.

Five people are said to be onboard the craft, which went missing during a dive to Titanic’s wreck.

It submerged from its support vessel, Polar Prince, on Sunday morning before losing contact about an hour and 45 minutes later, authorities said.

CEO and founder of OceanGate Expeditions Stockton Rush, British billionaire explorer Hamish Harding, renowned French diver Paul-Henri Nargeolet and Pakistani businessman Shahzada Dawood and his 19-year-old son Suleman Dawood are on the Titan.

A Canadian aircraft searching for the missing submarine detected intermittent “banging” noises from the vicinity of the last known location of the divers.

Search crews heard banging sounds every 30 minutes on Tuesday and again four hours later after additional sonar devices were deployed.

The Titan is equipped with a four-day emergency oxygen supply and it is estimated that the five missing passengers have just 24 hours of oxygen supply left.
