The boss of the Titanic submarine search has admitted rescuers hoped to "grab" the vessel and bring it to the surface before discovering it had imploded.
The chief executive of the Pelagic Research Services, Ed Cassano, whose team carried out the search for the Titan underwater vessel, revealed the plan to locate the submersible sitting on the sea floor with the five men all safe inside.
His team had envisaged four possible scenarios, with the best being that the Titan was resting on the seafloor but had lost the power to come back up.
