No survivors as Titan sub wreckage found on ocean floor

The five people aboard a missing submersible died in what appears to have been a “catastrophic implosion,” a US coast guard official says, bringing a grim end to the massive international search for the vessel lost during a voyage to the Titanic.

A robotic diving vehicle deployed from a Canadian ship discovered a debris field from the submersible Titan on Thursday morning on the seabed some 488 metres from the bow of the Titanic, more than four kilometres beneath the surface, in a remote corner of the North Atlantic, US coast guard Rear Admiral John Mauger told reporters.
