Our homes up. Cautious optimism. Those very same orange objects could be ocean trash when crews do find them or they could be the huge break desperately needed to help solve the mystery of flight 370. The whole world is watching and waiting for physical evidence of the missing plane despite those on board. They stay truth needs to be revealed. We want malaysia to apologize for the information caused confusion in the first week which delayed the search mission. And we want the malaysian government to apologize for irresponsibly announcing on march 24th that the plane had crashed. Our reporters and experts tang by, toward bring you the very latest information so lets get started. Kyung lah with the search planes that took off. Do you know iffist in planes are trying to relocate those four orange objects . Whats going on with that . Reporter what we do know is that the secretary of the ten planes are expected to take off. Expected to take off moments from now. There are going to be a total of ten planes. That is going to be one of the targets. But what is really going to come into play with those four objects that youre referring to are the sea vessels. There are ten sea vessels that will be working. Theyll be chris crossing back and forth to try to confirm whether any of the objects spotted by the planes are in fact connected to the missing plane. It is the sea vessels that will be able to pick them up and make that confirmation. Not those planes. So very important today. More of the sea vessels there. The most weve seen throughout all of this. Do we know how much of a new search area, how much the search planes have covered . Reporter we know yesterday they did comb through about 280,000 square kilometers. Thats a significant size. If you compare it to how it was on the very first day they were only clearing about 30,000 square kilometers. So it is significantly jumped day by day. And part of it is that that clock that youre referring to is ticking and ticking very loudly. There are only a certain number of days. Approximately seven to ten days left for those black boxes. The battery on the black boxes which sends out a ping for it to be detected. So thats certainly all the search teams are aware of that clock and they are racing to try to find the debris before that battery runs out. And lets talk about the australian Prime Minister expected there at any moment to give a press briefing. I believe we have live pictures from where hes going to give that briefing. There it is. Tony abbott will be speaking very soon here. Is this a morale boost . What is the reason for the visit . Reporter we dont know exactly what the reason for the visit. Is we know that he was spotted here. He is on the base. He came here about an hour ago. The anticipation is that he is going to be meeting with the search crews. He is going to be shaking some hands and making some comments to the press just about how its going. Were not sure if he will make any specific announcements. But we are anxiously awaiting his comments. Yeah. And kyung lah will be there and we will report it as soon as it happens. Thank you very much for that. Lets talk more about the search as we head into monday morning off australia. Joining me now, our panel this hour. Tim taylor, an underwater ocean explorer. Aviation attorney is here and of course, miles obrian. So tim, theyre heading out there with the ping detection device. Which is new. This one is on a ship, correct . Whats going on . Well, it is the same one, i believe. They loaded it on to a research vessel. These assets are systems that they can deploy across the World Without having them attach to a ship. They can put it on any ship of opportunity. Thats what theyre doing now. It is called the ocean shield that theyre putting the u. S. Pinger locator has been put on the ship. It has big ocean shield on the side. They have a few minutes, a few days left to listen for that pinger and everything they can do, theyre going to try to do. So getting that pinger, that acoustic hydrophone and listening. Even if theyre in the wrong area, at least theyre trying. And there is the shift that were looking at. Lets talk about this. As we await, we want to tell everyone, were awaiting a News Conference from the australian Prime Minister. Tony abbott expected to speak there. As we talk about the pingers, there are some who feel that maybe the time has passed. If not, then it is rapidly deteriorating to find the pingers. Yeah. I think we mentioned the cockpit voice recorder in the sully flight, the one that handed in the hudson river, which was of course exposed to water and of course was recovered with no problem, never pinged. So they dont always ping. Theres a lot of reason to believe the air france 447 devices never pinged because they sent the hydro foam pretty much right over where they found it two years later and didnt hear anything. A shred of evidence, theyll put it in the water and hope they hear something. They dont know. They dont know either. And listen, thats if the weather cooperates. Theyre not up against only weather. Theyre up against the ocean, currents, depths. Theyre up against so much at this point which is unfortunate but theyre trying. I have a few questions just in the timing. And i think everybody is probably togs around some of these things. The pinger they last heard which was the satellite, it was like the last handshake they had from the plane. I know that there are Security Issues involved but i dont think weve heard anything as to whether or not that could be the point of impact. Have they gone there before looking farther north. I have so many questions. As we have been saying, we have so many more questions than answers. I dont know for sure if theyve gone to that last point. That last handshake. I would imagine they would. That would be logical that they would. It is a logical place, of course. That kind of half handshake that weve been talking about. Which you know, weve been trying to figure out what that might be. One of the leading scenarios would be, it could be outright impact. More likely as the plane was losing its fuel, it was shifting. Electrical distribution. A toll of five generators. Four on the engines and then one in the auxilliary power unit. And as they were turning off and turning on, as it were, to keep electrical power going, that half handshake might have occurred. Okay. And i want to tell our viewers, youve looking at the small little box and that is because were waiting for a press conference from the australian Prime Minister, tony abbott. At any moment, he is expected to come out. Necessary perth, australia. No one is sure why he is there. If this is a morale boolt boost, if there is some sort of information he will give. Well carry it right here on cnn. My question to you as the malaysian government says, it will not give up on this search no matter how long it takes. Is that really realistic . Well, i think we have to take them at their word. As it relates to the search. I think this search will continue for at least the 30 days. It will probably continue for some level after the 30 days but i think each nation will end up evaluating its participation in the search as it continues to go forward. One other point i want to make, the malaysians are running the investigation. The malaysian government. Under their accident investigation procedures, which are part of their law, investigations are private in the sense theyre not conducted in the media or the public. Theres a great deal of information coming out. And were talking about some of it now. That typically would not be released as part of the briefings. But rather the investigators. So were engaging in speculation regarding information probably would not customarily be released. I think that there is information being releesd, even misinformation, is what is createding the problem here. Were talking about how long can this go on. And of course, hopefully they will find something very soon. As you have been involved in searches. How do you figure out when is the right time . Thats a human thing to do. This is the sensitivity to the families. If youre doing sheer numbers and they want to find this thing and put every as it they can. If you put one degree search vessel on location with one autonomous vehicle, could it take you, assuming they can narrow down the search area to just say 10,000 square nautical miles. You will take eight years. What are the parameters . You wont launch every day. Ooufl weather, down time for maintenance. So a vehicle will probably map 100 square miles a month. Thats assuming all the down time and travel time. Youve got two vehicles launching two of these bluefin systems they have here, it would take four years of looking on the bottom if they dont have the pinger. Do they have the budget . And conservatively, 700 million to do that. These assets arent cheap. Miles obrien, do you want to respond to any of that . I have another question. It is important and tim brings up such an important point. Were talking about this giant space. And in the case of air france, it was narrowed to 100 square miles the size of new mexico. To even call that a search zone is really kind of a stretch. It is just a huge hunk of ocean. And theyve determined this based on some very sketchy information as it is. So the odds seem very much stacked against them. Mark, how much of a role, i imagine it has some, does money play in these situations as to how long the search continues, whats the exposure to the company if they do stop. There are those questions. Well, i think all these questions are swirling around out there, don. The malaysian governments in charge of the investigation presumably at this stage, theyre ones that would be primarily financially responsible as the search efforts continue forward. Certainly weve heard at an earlier time during this search that the, our navy had put aside something in the order of 4 million and it had already expended 2. 5 million. Tim just indicated, were talking about hundreds of millions of dollars. Theres no right answer that will address all of the questions associated with when do you stop the search, when do you cut it back. There is no right answer. There are too many constituencies associated with that particular question, and the answers. Yeah. All right, guys, miles, mark, everyone. Stick around. Well have a demonstration a little later on. I want you to stick around and talk about it after the break. You see it, were waiting for a press conference from the australian Prime Minister. He is at pearce air base where the investigation by air and sea is being conducted. Not exactly sure what he is going to say, why he is there. Well bring it to you live on cnn. Coming up, well focus on the angles that have not been covered very much. Right now an american pinger, they are loaded up and ready to head to the search zone. Up next, when the search for flight 370 goes below the ocean they will face new challenges. So you can have a getaway from what you know. So you can be surprised by what you dont.

Australias Prime Minister tony abbott speaking in australia now. Thank you. To all of the personnel involved in the search for illfated flight mh 370. At the moment we have some 550 personnel on this base involved in the search from australia, from new zealand, from the United States, from malaysia, from china, from japan, and from korea. I want to thank all the countries involved in the search. I want to acknowledge the extraordinary work of the Malaysian Air force. The Malaysian Air force is not just here right now but it has been in the air searching for three weeks now. And it really has been an extraordinary effort by the aviators from malaysia to come down here over the last few days after all the efforts theyve put in earlier in this search. It has been tremendous to see the International Cooperation here. We have regular military cooperation with the United States, with new zealand and with malaysia. To see also the cooperation with us from china, from japan, and from korea, it demonstrates in a humanitarian cause the nations of the region can come together to work for the betterment of humanity. Can work to resolve this extraordinary mystery. Can work to try to bring peace and closure to the families of the 239 people on board that illfated aircraft. So it is an honor for me to be here, to be able to say thank you to the extraordinary men and women who are involved in this search. It is also an honor for me to be here with air chief marshall retired Angus Houston who will be helping to coordinate the earth in the days and weeks ahead. It is good to be here with the deputy Prime Minister and minister for transport and the minister for defense, senator david johnson. All of their agencies are working together to try to get the best possible outcome. Weve got the australian Maritime Safety authority, weve got the various air Investigation Bureau as well as naval personnel, air force personnel, and Army Personnel here in australia. So it is good to be here to salute the professionalism of all the personnel involved. And to honor the work of all the countries involved in this very important search. Im going to ask each of the other gentlemen here just to say a few words and then ill take some questions. If we could, please, confaine the questions today to questions about the mh 370 search. Ill have an opportunity later today to take questions on other subjects. Thanks, Prime Minister. Im delighted to be apointed to coordinate the efforts on this very important full backs we have out in the southern ocean. My job will be to head up the joint Agency Coordination center. I will be coordinating with my people at the interNational Level, at the National Level and of course, most importantly, with the families and the media and can i say that my heart goes out to the families who have lost people on this terrible disaster that has befallen Malaysian Airlines. I will obviously be focused very much on coordination. Im not here to run the search. Im not here to do the detailed operational stuff that is being taken care of. Very professionally by the australian Maritime Safety authority and the defense force. Can i say that as a former cdf im immensely impressed with what ive seen today, with what ive heard today, and im delighted that we see the nations of the region coming together to do this very complex search and rescue operation. Thank you. Im pleased again to be back at pearce just a week after i was here last time. And ive noticed the growth and the momentum of the search. Even though this search has been going for three weeks, more aircraft, more ships are being added each day. Te momentum and the determination of all of those involved, to follow the leads and hopefully eventually locate the resting place of mh 370, is much appreciated by everyone. The International Effort is particularly notable and i commend all the countries involved in making sure that we work constructively together to get best possible outcome as quickly as possible. The role of Angus Houston, particularly the investigation of any of the activity, of any of the debris that comes to shore and also, to try and work toward finding the cause of this event will be particularly important. I think the west Australian Government for available its emergency central to act as a nerve center for this operation and to help support the activity thats are currently during at the australian Maritime Safety authority in canberra and the Safety Bureau who have great skills in investigating aircraft incidents and being able to work toward identifying the cause. It is a priority for to us try to recover the black box recorder of this aircraft as soon as possible. It is, of course, an australian invention, and our Safety Bureau has a particular skill in being able to interpret that data when it becomes available. So there are lots of challenges ahead. The key task now is to focus finding whatever we can so that hopefully, the location of this aircraft can be properly identified and we can then proceed to the next stage of the investigation. Thanks. Ladies and jerks today well have more than 100 people in the air over th. Well have over 1,000 sailors in the area look fog debris. Can i pause to pay tribute to the commanding officer, dave turn he who has been able to ramp up the provision of food and accommodation for more than 500 people in support of the air operation. This is a huge task for australia. It has gone seamlessly. It is a great tribute to the air forces of the various nations involved. Theyre often flying three and four consecutive 12hour missions. They are committed, they are most brave and courageous. I want to thank them and all those who support them to try to solve this mystery. Lastly can i thank you, ladies and gentlemen of the media for the professional way youve gone about conveying the difficult task of giving information to your countries. Were doing our very best.
