Titanic Submersible Mothership That Plunged Five Men Into Doomed Dive Returns To Shore

The support ship that launched the doomed Titan submersible has returned to port in Canada, following the sub's catastrophic implosion during a dive to the Titanic wreckage.

The Polar Prince arrived in St John's Harbor, Newfoundland, on Saturday morning, docking at about 8.15am local time as sun broke through the morning haze.
