ROV to Find Flight 370; ROV Would Be Used To Find Flight 370
CUOMO: Welcome back. Right now an unmanned, underwater vehicle, the Bluefin-21, is about to head back into the ocean to scan the seafloor for flight 370. Now, if the device finds the plane's wreckage what happens next? Rosa Flores has the answer.</s>ROSA FLORES, CNN CORRESPONDENT (voice-over): This could be the key to solving the mystery of Flight 370. It's a remotely operated vehicle, or ROV for short. Once wreckage of Flight 370 is identified, an ROV like this one is likely the next crucial step in finding the plane's black box.</s>UNIDENTIFIED MALE: All of the hydraulic is running.</s>FLORES: It's controlled from the surface using this joy stick, has lights to illuminate the stark black of the ocean deep. Cameras transmitting back footage in real-time. And high frequency sonar to combat the notoriously difficult visibility in the area of the Indian Ocean where the plane is believed to be. But most importantly, the ROV has robotic arms called manipulators.</s>UNIDENTIFIED MALE: It has jaws, open and close the jaws.</s>FLORES: They are essentially mechanical hands, able to retrieve objects from the ocean floor, are deeper than any human could withstand.</s>UNIDENTIFIED MALE: Strand and retract.</s>FLORES: A second manipulator can be equipped with tools for cutting through metal such as on the fuselage of a plane.</s>UNIDENTIFEID MALE: The ideal if there was a black box. Not a problem at all for a ROV to pick it up in a basket and recover it back to the vessel.</s>FLORES: Experts say top priority for investigators is to retrieve both the flight data recorder and the cockpit voice recorder. This ROV called the Triton SLX can go to depths of 10,000 feet. But the ROV that is brought to the wreckage of Flight 370 could have to withstand the pressure of around 15,000 feet of water. Underwater pulses were detected at that depth last week. And unlike the Bluefin searchers are currently using, the ROV is connected to a boat through a line called an umbilical and has a constant power source and is able to feedback information immediately.</s>UNIDENTIFIED MALE: The ROV can stay submerged for days.</s>FLORES: And the hope is with these capabilities, the ROV will finally manage to bring some answers to the surface. Rosa Flores, CNN.</s>CUOMO: All right, so that's what the ROV will do. Later this morning, we are going to take you inside a submarine to demonstrate just how hard a search this is. That is Martin Savidge. He is standing outside what later this morning he will be inside when he takes a test dive. You're not going to want to miss it.</s>BOLDUAN: Absolutely not. Also coming up next on NEW DAY, families of Flight 370, 370 passengers, are taking questions to the top. They want answers to more than two dozen questions and they want them quickly. Some of them very technical questions about the search in the investigation. We'll have much more on that.</s>CUOMO: And the fighting intensifying in Ukraine as Vladimir Putin admits to sending Russian troops into Crimea last month. We'll tell you what happened and how it could affect international talks.
