Australia's P.M. Say Effort Ramping Up
BALDWIN: Australia's prime minister didn't shy away from what he sees as the truth about Flight 370. Tony Abbott said today all evidence suggests the plane went down in the ocean and everyone onboard was lost. He also gave an exclusive interview to CNN's Atika Shubert, where he insisted that Australia will find the plane if it can be found.</s>TONY ABBOTT, AUSTRALIAN PRIME MINISTER: The effort is ramping up, not down. We'll have more aircraft in the sky tomorrow. We've got more ships in the area. So we are ramping this effort up. We owe it to the families of the 239 people on board. We owe it to the anxious governments who want to know what happened to their citizens. We owe it to everyone who travels by air and wants the skies to be safe. We owe it to the whole world, which has been transfixed by this mystery now for some time. We owe it to everyone to find out as much as we can, and that's exactly what Australia is doing.</s>BALDWIN: Australia's prime minister, Tony Abbott, there. For now, any chance of finding Flight 370's black boxes may depend on this ship. It's called the Ocean Shield. It's carrying this cutting- edge detector that can pick up those faint pings broadcast by those black boxes. And CNN's Will Ripley watched the Ocean Shield begin its journey, and he explains why there is no guarantee it will be successful.</s>WILL RIPLEY, CNN CORRESPONDENT: We are heading away now from Garden Island, off the coast of Western Australia, where the Ocean Shield just moments ago began its three-day journey to the search zone in the Indian Ocean, where it will attempt to locate the wreckage of Malaysian Airlines Flight 370. This journey and what's going to happen is really unclear, and here's why This ship has a lot of crucial technology on it, technology that could be the key to solving this mystery There's a black box locater, a giant underwater microphone. that is towed behind this boat, listening for the sound from the in-flight data recorder and the cockpit-voice recorder. But the problem is, that giant microphone, as powerful as it is, it can only hear from about a mile around, so we have to be within a mile of the black box to get a signal And with only about a week of battery life left and still no clear leads as to where 370 may be in this massive Indian Ocean, the technology pretty much will be useless unless we can narrow down that information. There's other technology on this ship, as well, an underwater drone that can scan the ocean floor looking for debris. But again, even that technology can only cover about 50 square miles a day, and when you're talking about a search area that's well over 100,000 square miles, the task of finding this is still too difficult, even for technology like this. But nonetheless, the journey for the Ocean Shield, now underway, the hope, if this ship can be positioned in the Indian Ocean, if we can get it close to the area, and then if one of the search planes or one of the search boats spots some debris, something that's connected to Flight 370, this ship will be ready to help solve the mystery. Will Ripley, CNN, off the coast of Western Australia.</s>BALDWIN: Will Ripley, thank you so much. Coming up next, a couple on board that plane had just gotten married. The groom apparently saved up for his first trip abroad, and so, CNN sat down with their family for an emotional look at the couple's final days and the worst moment since their disappearance.
