Youre in the situation room. Searchers race against time to find traces of flight 370. Here are the latest developments. Questions are now being raised about a new map said to show the airliners radar track and shows a much different flight track. The airliners turn is being viewed as a criminal act. Malaysian officials now say the last words from the cockpit were good night, malaysian 370. The earlier version was all right, good night. The change raises questions about the handling of the investigation. And as planes get ready to resume searches of the airliner, pinger locators are on the way to the search zone but the batteries powering the black box signals will likely die within days. Our analysts and our reporters are standing by in washington as well as around the world with the kind of special coverage that only cnn can deliver. Lets begin with our Senior International correspondent nick roberson. Hes joining us with the very latest from kuala lumpur. Nic . Reporter wolf, weve been hearing increasing frustration from families unable to get answers to key questions about the investigation, frustrated with the small bits of information that theyve been handed. Theyve been frustrated because they wanted to know more about where the plane flew, more from malaysian officials. Today, we began to get a better understanding of precisely what theyve been asking and and now their questions are being finally put to officials. This is what weve learned. This map of flight 370s radar track was much of the reason for upset by survivor families last week. The image captured by still photographers in the family briefing. It shows a very different route from the left turn until now and raises more questions about what exactly happened to flight 370, questions the family members were unable to ask at the time. The family briefings were chinese officials of flight 370 passengers say they created the map from publicly available data. A source with knowledge of the investigation tells cnn that beyond doubt the new map, if accurate, shows that someone with excellent flying skills was at the control of the aircraft, that no one on board would have felt the turn. Its a claim thats getting heavy pushback from malaysian officials. As regards to the issue of information as we revealed outside the press conference and speculation and diagrams and google or anything else in the internet, i cannot confirm or discount. I can only explain what i informed you in my piece. Reporter investigation officials insist privately this new map is not theirs and does not match malaysian radar readings. Despite refusing to comment publicly, officials did say that all of the radar data is central to their investigation. The manner of the air Traffic Control at a time of the aircraft made the turn back is one of the very Important Information for the investigators to look at. Reporter at a background briefing given to cnn, they believe flight 370 was, quote, flown by someone with good flying skills. And now a government source says they consider the turn a criminal act committed by one of the pilots or someone else on board. Oh, this is great. These are the controls of the aircraft here . Yes. Reporter wow. Cap pen zaharies friends refuse to believe that he could be the criminal controlling the plane. I think you will come to stage when people think hes a hero. When things come out, i think they will see that hes a hero. Reporter they rallied to his defense, showing me pictures of a young captain zaharie at flight school. But for some, the new map is casting a shadow over captain zaharies memory. Now, the source who has knowledge of the investigation is also a friend of captain zaharie but he told us that emotionally he doesnt want to believe it but logically has nowhere else to turn with his conclusions. The question for him, was the plane being flown on this arc on the last hours of its flight, was it being flown on an arc towards the sunrise, was the person at the controls, who was controlling the aircraft trying to land it on water so that it would sink without trace, make it so much harder to find . Wolf . So nic, based on this source that you have there, my sense is that what hes suggesting is that it was a criminal act as opposed to a catastrophic mechanical failure on the plane. Is that right . Reporter this source has a lot of knowledge, a lot of information about this specific aircraft, about operations with Malaysian Airlines and a lot of knowledge about the way that the this captain zaharie flew his aircraft. Hes a man who has a lot of information. He has a lot of information about the region, the popping to gra fee, and these are the questions that hes coming to, putting together all of the information that he now has available to him and for him it very much does seem and its an inescapable deduction of logic, he says. He cannot get away from the fact that whoever was flying the aircraft towards the dawn on saturday morning was somebody that knew how to fly the aircraft, knew how to fly it well, had excellent control of it and it leaves him with a very inescapable logical conclusion, wolf, one that he finds painful. Yeah, i can understand that. Nic robertson doing excellent reporting for us. Thank you. Lets bring in evan perez and miles obrien and cnn Law Enforcement analyst, former assistant fbi director, tom fuentes. Miles, lets start with you. What do you make of this information that they are making out . A 270degree turn right all the way down to left, its very difficult, wolf, to come up with a scenario where that is some sort of a mechanical failure or malfunction. If a pilot was in a bad way, rapid decompression, fire, whatever you want to say, he or she would not take that long way around to gain that direction. It would be a sharp turn to the left. And so its very difficult ive talked to a lot of pilots about this, its very difficult to look at that diagram and not say that it was an intentional act of some kind. That jives with what nic robertsons sources have been telling him. The one thing i might quibble with on his sources, that could have very well have been flown by autopilot. It could have been flown automatically and in a gentle way that the passengers would have had no idea. Tom, i know you have good sources over there in malaysia as well, that they are coming to the conclusion that it was a criminal act responsible for the disappearance of this plane . No, ive heard nothing new today as far as this issue. My question would be, what is the source that the plane made that righthand turn instead of the previously believed lefthand turns . What about all of the radars and experts that have been looking at the radars from the civil radar of malaysian aviation as well as Malaysian Defense force radars that were supposedly analyzed the first couple of days of this incident . Im questioning just how do we know that this new information is even true in the first place . Thats a good question. And i guess well only know once this investigation really comes to some sort of conclusion. But evan, i know that youve got good sources with the fbi. Tell us the latest on what they have discovered as far as the captain, the pilot of this plane, the hard drives that they were investigating to see if there were any indications there of wrongdoing. Wolf, one of the more puzzling parts of this whole thing is that its natural, according to u. S. Officials, its natural to suspect that whatever was happening was happenings inside the cockpit and for to you bring full attention to the two pilots and the captain in particular. But they found nothing. Theyve looked at the hard drives, they are still going through it, they havent turned over everything to the malaysian authorities but they have been sending some regular reports of what they found. And so far, they have found nothing incriminating. Theyve even recovered some of the deleted data that we have talked about here on the situation room and theyve found the deleted data was actually overwritten data and doesnt indicate that the pilot was trying to cover his tracks, per se, nothing to indicate that he was trying to hide anything. So they are left puzzled. Still here 24 days later, they dont know anything more about what these two pilots were up to before flight 370 took off. Wolf . Miles, we learned that the malaysian authorities have new information on the final words coming from the cockpit back to ground control. Originally we heard the copilot supposedly said, all right, good night. Now theyve put out a press release, the ministry of transport malaysia saying that the final words to air Traffic Controller was good night malaysian flight 370. What, if anything, does that say to you other than the fact that the malaysian authorities cant seem to get their act straight four weeks into this. They now finally have the final words correct as opposed to earlier when we thought it was all right, good night . I think thats the most important takeaway, wolf. That is standard procedure to do that. So that means that that response was closer to a standard response. The pilot is expected in that case to repeat the frequency that he or she was assigned. In this case, that apparently isnt what happened, although, we havent seen a complete transcript 25 days in. We have not even see a transcript of air Traffic Control to the crew. I looked it up in the case of the asiana crash in san francisco, international airport, a transcript was released within two days. We actually heard the communications within two days. The faa released it. Theres no reason why we shouldnt be able to hear all of this to hear what the Malaysian Authority controllers were saying to that crew and, for that matter, what were they saying in ho chi migh city. I hope they change their minds better late than ever. Then we can move on a little bit. Guys, stand by. Up next, aircraft are getting ready to resume the search for flight 370. Well go live to perth, us a ve australia. And ill speak to one of the military commanders in the height for the airliner. When it comes to good nutrition, my daughters an expert. Hi dad.

Time is quickly running out to find the black boxes. Kyung lah is in perth, australia, which is the staging ground for the planes. What is the very latest, kyung . How does it look there . Reporter well, were expecting the very first planes in the air in the next hour or so and the pressure is mounting here as the clock continues to tick. The race begins now in the electronic hunt for flight 370. This giant Australian Navy ship now heading for the indian ocean carrying americas towed pinger locator. It can hear the satellite pings from the black box. The batteries expected to last only about another week. Travel time to the search area, three to four days. But even if they arrive in time, the current search zone may be too big for the device to be useful. I can search approximately 50 square miles a day. So really, if were searching for a beacon and were living on borrowed time, i need something that is less than 1,000 square miles. Reporter the search zone is 100 times that. The clock winding down, the search so far has been a frustrating chase of objects spotted from the sky. But when hunted down at sea, the objects turn out to be either Fishing Equipment or jellyfish. Planes touched down again with little news. More than 100 personnel and search planes like that one in the air, 1,000 sailors at sea, those numbers, the Prime Minister says, will only increase as the search operation intensifies. Thank you so much. Thank you. Reporter australias Prime Minister thanked the search teams working around the clock, saying this is about more than just finding one jet, its about anyone who flies on a plane. After dramatically moving the search zone last week, the Prime Minister says they are now looking in the right spot. Its the best information we have. Its the best analysis that we can get. And its the most professional search that can be mustered. We are giving it the very best shot we can. And if anyone can find this aircraft, its us. Reporter in malaysia where families have loudly protested the governments handling of the investigation, a change in an important detail. For weeks, the government said that this was the time and last words from the cockpit. We got the last conversation from the cockpit that says, all right, good night. Reporter and now in a statement it says the last spoken words were good night malaysian 370. Its not the words that are so much the issue. Its a fairly standard signoff. The question is, why didnt the malaysian authorities know sooner . Why are they releasing it now and how are they handling this investigation . Wolf . And the weather is getting ready sunlight on Tuesday Morning in perth. The weather is okay . It looks like its going to be a good day to fly . Reporter well, there is some weather in the search area. Theres a system coming through. Its not expected to be terrible but weather is always a factor. The waves expected to be a little higher, wolf. Kyung lah, thank you. Joining me now is a member of the new zealand air force. Commander, thanks very much for coming in. Do you have any reason to believe all of you guys and i dont mean just new england. Is the entire multinational effort any closer to finding this plane . At the moment, wolf, its a fairly intensive search going on in that particular area and what were going off is, of course, that weight of evidence pointing to the current area being the correct location. Obviously, as youve alluded to earlier in the bulletin, as of yet theres been no sightings that can be directly linked to flight 370. It can become at times frustrating but we certainly believe its just a matter of time. How confident are you, commander, that youre even searching in the right area . Again, it just comes down to that weight of evidence that is there. Of course, if we knew exactly where it was, we would go there. But the search area thats being covered every day is comparable to the size of new zealand. So as much as we have a lot of access that is in the area, both in the air and on the surface, its still a very large amount of ocean that we have to cover and the key to obviously doing this sort of thing is maintaining that search integrity, making sure that the area that you cover, you do cover properly and that way its almost as important as finding the actual evidence of mh370 is discounting areas so we can then move on to others. Commander, you dont have to share the classified information, your Sensitive Information with us, but as a general principle, do you have access to secret information that leads you to believe that you are searching in the right area other than the Public Information thats been released . With the information involved and the large degree of spotlight that you can see, were going off the same information that has been given to the media. So theres nothing confidential, u. S. Satellites or sub submarines, information that they are sharing with you that is pointing this specific area . Certainly no information thats been shared with me, wolf. Okay. Lets talk about the frustration. A lot of men and women are involved in this search. Its been going on now were in the fourth week. How frustrating is it to your men and women who go out there and come out with jellyfish or garbage and junk and nothing to do with the plane. How frustrating is that, commander . Its one of the realities of any evidence, there are always highs and lows. If i can speak about the aircraft yesterday, we identified 14 objects of interest throughout four hours on station conducting the search there. Thats some 1200 miles due west of perth. During that time, each of those contacts is then reacquired, investigated, photographed so they can tell whether they are objects of interest. And out of those 14, there was only two objects that we thought were worthy of further investigation, which then were passed back through to the us a str australian Maritime Safety authority. Thats also due to the sea state as well. If i can compare that to a previous mission, there was around 70 contacts. As you can tell from such a dense area, although its frustrating, theres a lot of it does generate a lot of excitement each time something is seen to go around and have a look again. With the crews that we have there at the moment, this is the second screw. We swapped those guys out last week as the first crew was reaching its maxi
