The US coastguard has recovered remaining debris from a submersible that imploded on its way to explore the wreck of the Titanic, killing all five on board.

Officials said the salvage mission conducted under an agreement with the US navy was a follow-up to initial recovery operations on the ocean floor roughly 1,600 feet (488m) away from the Titanic.
