Transcript for Zeroing in on the Missing Malaysia Airlines Plane
And as we join you, the global mystery continues. And so does the all-out race against time. Somewhere, right now, the black boxes from that missing passenger plane hold answers on what happened to all those lives onboard. But with every day that passes, their batteries are fading. So, tonight, we have the latest on the search and also the pilots. Did they leave any clues in their last words from the cockpit? ABC's David Kerley starts us off with what is new tonight. Reporter: Tonight, flying over the massive Indian ocean, American sub hunters, looking and listening for flight 370. A race because one-third of the life of the batteries of those pinging black boxes now gone ten days into the search. As ABC reported, much of the search is moving south, to off Australia, following the southern corridor of a new map, showing the possible last location of the Malaysian 777. New details, tonight, about what happened in the cockpit. The final words from the flight, all right, good night, came from the co-pilot, 38 minutes after takeoff. Malaysian officials are analyzing the recording, seeing if the co-pilot was under stress, if someone was forcing him to speak. Malaysians also offered contradictory information today on the timeline. But sources say it points to a deliberate act. With the turns that the airplane made, even if we don't know the altitudes, someone was in control of this airplane and knew what they were doing. Reporter: As we learned in a simulator recently -- there are a couple of ways to change the direction of a 777. But it's difficult to do without the other pilot noticing. So, as this search intensifies, questions. What about the massive depth of the Indian ocean, more than 15,000 feet in some parts? And will those black boxes help? In the crash of an air France jet, it was a minisub that traveled thousands of feet under water to pull up the boxes, which revealed a technical problem and pilot error as the cause of that crash. But reaching the box will help if any debris can be spotted from the air. Our first clues will be debris. And tracking currents, they can trace to where the plane could be. Searching around Malaysia, with a focus really in the south. Me in the north, some in the south, off Australia, they're concentrating quite a bit. A brand-new U.S. Sub hunter, with high technology, is arriving in Australia tomorrow, looking for signs of debris, the plane, or any of the passenger, 239 people onboard. And families still wondering where they are.
