"Very few assets in the world that can go down that deep." Expert says rescue would be complex mission
From CNN's Greg Wallace
If search crews locate the missing submersible deep in the ocean, authorities will face a highly complex mission to recover the craft and any survivors, an expert said Tuesday.
“There’s very few assets in the world that can go down that deep,” said Ret. Navy Capt. Ray Scott "Chip" McCord, whose 30 years of experience includes overseeing several salvage operations.
McCord said sophisticated naval craft could reach the wreckage of the Titanic at a pace of about 1,000 feet per hour. At more than 12,000 feet below sea level, diving and surfacing could take a full day.
At these depths, a remote craft would be able to explore a limited area rather than cruise along the ocean floor, he said.
“When you’re going deep, you usually go up and down like an elevator,” McCord said. “When you’re going shallow, you can go further like a nuclear submarine.”
Once crews have narrowed their search, they could deploy a cargo van-sized remote-operated craft to locate the submersible. The remotely operated vehicle, or ROV, is tethered to a surface ship with a two-inch thick cable to provide power and communication. The ROV could be moved to a Canadian port by military aircraft, loaded onto a ship by crane, and then steamed to the search site, McCord said.
US military ROVs have electric motors and

It's all suspense building toward a grand crescendo of loss. At this point with the O2 deprivation, there are probably more than 1 person expired already. Nobody knows what the actual status of the Oxygen tanks was after they hit the bottom, so the air could already be gone and this turns into a recovery mission tomorrow. They are just running out the clock now, hoping that they can pinpoint the location so they can bring in the equipment to bring the sub to the surface. Everyone involved already knows that there will be no survivors even if they get it found today.
