It's likely too risky to try recovering the remains of Titan's passengers, an ROV expert said.
The search for the sub near the Titanic has already cost millions; recovery would cost even more.
The five passengers on the Titan sub were British billionaire Hamish Harding, French submersible pilot Paul-Henri Nargeolet, British businessman Shahzada Dawood and his son Suleman, and the CEO of OceanGate Expeditions Stockton Rush.
The Titan submersible had made three previous trips down to the wreckage.
But shortly after the vessel vanished Sunday, key questions began emerging about the design and operation of the Titan.
