A massive search operation is underway to find and rescue a submersible and save the lives of five people onboard that vanished Sunday in a remote part of the North Atlantic.
The five people had embarked on an eight-day expedition to the wreck of the Titanic and their dive should have concluded within around eight hours, including the descent and ascent of the vessel.
But the crew on board made no contact with their support crew for over eight hours, prompting a search operation to rescue the five men.
