Investigators have a better idea of exactly where flight 370 made its sharp left turn away from its designated flight path to beijing, and just how high the airliner was flying afterwards. And off the waters of south korea, 270 people still remain missing two days after the ferry made a turn and capsized. We have word on what is happening in the frigid waters of the capsize boat. And now, police in boston are on the hunt for sibling lone wolf bombers, what have we learned since . And are American Cities any safer . Ill ask the deputy who runs one of the most counterterrorism divisions in the world. First, well have more on the sunken ferry off south korea. The 69yearold captain of the ferry is now under arrest, although prosecutors say he was not at the helm of the ship when the disaster unfolded. And we have this new cell phone video taken on the ferry as it slowly capsized. Remember how the captain ordered the crew and passengers to stay where they were as it capsized. And being oh obedient, many of them perished. Cnns kyung lah has more from south korea, tell us what is happening in the water right now. Reporter what is happening right now is that the coast guard tells us that they have managed to lay these search lines, if you will, underneath the water around the ferry, around the third floor. And the fourth floor. And what that allows divers to do is to painstakingly make their way around this ferry and look room by room. They tell us that so far divers have not been able to get inside the vessel. But that is the goal. They have been able to glimpse inside, but they cant exactly make out what some floating objects are. So at this point it is still a 24hour search operation. And they are still ferventalfer looking for survivors, bill. First of all, is there hope that there are air pockets to keep them alive. And is there a plan to bring the giant hull back to the surface . The cranes are the goal here as far as lifting the hull out of the surface. But this is a longterm goal. This is not something somewhat is going to happen right away. The cranes have to be in place and they will slowly lift it. But this could take weeks if not months. And it is a very large vessel. It is going to take some time. Is there hope . It is a very difficult thing to talk about. Because the odds, the facts are absolutely against any survivors being pulled out of the water at this point. The possibility of air pockets, perhaps, but it is very, very slim, bill. But no one wants to tell these parents. And remember, were talking about many, Many High School students here. No one wants to tell these parents that they have given up hope and that this is a search for any survivors. And this is heartbreaking, this was a vice principal. He got off the ship, they found his body. Apparently he had hung himself. And rough translation of the suicide note. Please hold me responsible for this. I pushed for the school excursion. Cremate the body and spread the ashes over the site. I may become a teacher in the after life for the bodies yet to be found. What is sad is to think of the low birth rate in the country. So for a lot of parents that was the only child. Tell me about the cultural expectationin expectations of kids to listen to those in authority. Reporter well, there are a couple of questions, first regarding suicide. The oecd ranks korea the highest in suicide. There is a culture, a sense of shame that carries a lot of weight, a huge burden here. And when you talk about survivors guilt, it is a huge risk here. That is why there is so many counselors here at this particular dock. That is why theyre surrounding the parents. There is also stigma against mental health. So nobody is really talking to counselors right now. It is a cauldron right now, as far as parents and survivors. That is a huge problem here. There is another cultural thing that you touched on. The students who sat on this ship as it was sinking, they stayed in place as it was tilting. Why . Because children are taught here in south korea to be obedient above all else, to listen to your elders. That is truly prized here in south korea. So for us in the u. S. It is very difficult for us to understand how is it that they can stay put . But here it is an expectation that you would listen to a loud speaker warning from the captain of a ship to stay in place. I want to ask you about the fate of the captain in custody if you will hang out with us for just a moment. I also want to bring in our accident investigator. James, thank you for joining us. Were still trying to figure out what caused this calamity. You hear reports of passengers hearing a loud bang and things starting to fall below. Do you have a hunch as to what happened to tip it to its side . Sorry, bill, but i do not. The noise that it made could have been striking a rock, which could have caused flooding from outside into the vessel. I dont have information on the configuration of the vessel, unfortunately. Also there are other things that could have caused flooding. There could have been an internal breakage, a pipe through explosion or otherwise. Depending on the nature of that noise they heard. But certainly water got into the ship. Free surface water going to the low side took over. And caused the ship to capsize. Now, do you have any sense i know were all struggling to figure out what the configuration is. But airtight compartments in the bottom that somehow could hold out hope that some kids got themselves in there and sealed themselves. And some semblance of safety, is that Wishful Thinking . Well, i think i would hope that the air tight compartments that they got themselves into are in what would have been the top of the ship. Now the bottom because of she is laying upside down. Because there is a large auto deck and there are tanks underneath that, that they probably wouldnt get into. And it would be far more difficult for them to get out of the ship unless they are near the top of the super structure. Kyung lah, what charges are the captain facing . Lee joon seok, if i am pronouncing that correctly. What is he up against . Reporter he is hardly a novice, and your pronunciation is quite good. He is facing a series of charges, they range from bodily injury, leading to harm, to abandoning ship. These are criminal charges that carry anything from five years to life. It is something that these pare parents, the people you see on this dock, it is something that they wanted. They want somebody to pay but it is not helping them as far as bringing their children home. And he is not a novice, youre right. He has been a captain on the seas for many, many years. We should point out that he was not at the helm. The person on the helm was a much less experienced junior officer, the third officer on the ship. It so reminds us of the costa concordia, the captain claims it was the crews fault. Thanks to you, and kyung lah, in south korea, thank you, as well. And coming up. From flight 370, new information on where the jetliner was when it flew off course. Could save you fifteen percent or more on car insurance. S Everybody Knows that. Well, did you know bad news doesnt always travel fast . clears throat hi mister tompkins. Todd . Youre fired. Well, gotta run. Geico.

Off the coast of australia looking for missing flight 370. Michael holmes is live in perth, and Nic Robertson in kuala lumpur. Nick, good morning to you down under. What is the latest on the Bluefin Mission . Ongoing again . Reporter yeah, it is ongoing. Were waiting to get the latest update from the search organizers. It should have been in by now, and you think about it now, bill, that is three out of five missions had some sort of trouble. The fifth mission was aborted shortly after launch due to some problems with the navigation system, were told. That is according to the u. S. Navy. Since the bluefin did not go to the ocean floor, of course, there was no side scan sonar data to review on that mission. Of course, the bluefin21 was relaunched. Were told it is on its sixth mission. There were no problems with the first five. Bluefin21 had not identified any wreckage, but had when it was working performed pretty well in terms of the detail of that 3d side scan sonar images of the ocean floor, bill. Okay, you know, for weeks, we were under the impression, Nic Robertson, that the pilots turned off the transponder before they got into the Vietnamese Air space to avoid detection. But you have new information that counters that. Please tell us. Reporter yeah, what the source familiar with the investigation is telling us is that the aircraft actually passed into Vietnamese Air space. We remember the last communication at 1 19 in the morning over to the air Traffic Control cockpit, was passing over the Malaysian Air space. What were told is that it actually entered the Vietnamese Air space when it made that l d lefthand turn, quite a gentle lefthand turn. Were told when it made that lefthand turn over the malaysian peninsula that is when it climbed 13,000 feet. And held that altitude for about 29 minutes before beginning what was a descent taking it well off the malacca straits, traveling another 100 or so nautical miles before climbing back up in altitude. So what were learning for this source is that the turn happens in Vietnamese Air space, and then this climb in altitude, it seems to be a controlled climb in altitude. Yet again it is another piece of information that really doesnt solve this in any way. It perhaps provides useful clues for investigators. But really it is just another piece of information that really doesnt take us hugely further forward as far as investigators are concerned here, bill. And this one doesnt either. It involves the emergency location transmitter, the elts, your source said something on that, as well. Reporter yeah, he told us there are four of these automatic emergency locater transmitters on board the aircraft. One in the rear door, one in the forward door, one in the cockpit, the fuselage, the ones in the door are associated with the emergency evacuation chutes. Which become sort of an inflatable dinghies, if you will, a way to keep people afloat on the water. He said these hadnt transmitted on their frequencies or those frequencies had not been picked up upon by satellite or by nearby ships or aircraft in the area. These devices are designed to be triggered to come on, on impact, or on immersion in water. I discussed with him can you take inference from this that perhaps it didnt come in contact with water . You remember how the plane landed on the hudson, did the aircraft go like that and tip down underneath the waves before the water could get inside the aircraft and trigger the beacons . Perhaps it came on when it was sinking. This source couldnt say that, but this is one of the alternatives. Potentially that could be the case, but again, this is just another piece of information that investigators say it is odd but cant take it further forward than that, bill. Okay, nic, why dont we bring in experts on that and follow up on that. David souci, author of why planes crash. And a professor of physics at the Florida Institute of technology. I am sure, i butchered your name, apologies for that. And i saw something today, when the former commerce secretary, ron browns plane crashed in croatia, they did no go on land, these are four of the most dependable. What do you say about four of them didnt go off . Yes, this is very interesting, when the elts were developed in the 70s, the reliability rate was very low, only about 25 of the time did they go off. This has improved over time. The latest number we have is about an 80 activation rate. So there is a 20 factor that says they wouldnt go off. But all four . This is again one of the many strange elements of this disappearance, of which were into the seventh or so week of now, 43 days. Another question mark to add to the growing number of questions we have about mh370. Yeah, david souci, what do you know about these elts . Is it something you could shut off . Are they built into the raft slides, the emergency exit slides . Well, there are two or three different kinds were talking about here. The one on the nose is only a deceleration, the other two by the doors are activated by water. So theyre not expected to go off by a deceleration. The one in the back is activated. An elt by deceleration sensor and by salt water. But remember the two in the back once theyre in water that he cant transmit. Because theyre not sonar, theyre not sounds, theyre radio frequencies, so once theyre in the water they cant transmit sound. Let me ask you about the theory of the sinking. What is the depth and the pressure of the ocean on a plane like that do to the wreckage itself . Well, it depends on what happens if the plane comes down in the water. If the plane comes down relatively intact, it lands on the water and then sinks. If there is a large air pocket and it fills with water and the plane descends when it gets to a certain pressure, there will be a big pressure differential. So it will implode. However, if it fills quickly then the pressure will be equal on the inside and outside. And the plane will remain intact. And so at the depth of this plane at about 10,000 feet which is the depth of the ocean there were looking at 455 times atmospheric pressure. Wow, that is hard to fathom. We appreciate your in put. And coming up, two men sworn to protect the biggest target in the world, new york city. You know it was russia that tipped the fbi that Tamerlan Tsarnaev was a threat. Can we still depend on the russians given the situation . Ill have that and much more. If you wear a denture, touch it with your tongue. If your denture moves, it can irritate your gums. Try fixodent plus gum care. It helps stop denture movement and prevents gum irritation. Fixodent. And forget it. Deceleration, deceleratio i look at that, one, if it is alqaeda Central Command striving for the it is not relevant, give the appearance of relevance, by putting things out if they were alive and still operating. They have been degraded through an extraordinary degree of key operational commanders almost in rapid succession over a period of decades. So i think in some measure it is a propaganda piece. In another measure, alqaeda central has also had a habit over the past decade of foreshadowing events with some kind of symbolic communications. So you always have to look at that. Public appetite has changed when it comes to counterterrorism units. They would go into the muslim community, coffee shops and sometimes write down the license plates of every car in the mosque parking lot. You just dissolved that. I wonder why. Well, coming back into the nypd, were looking at every unit in the department, not just in the counterterrorism department. They were not violating any laws or procedures, but we looked at it as was it no longer necessary . If i looked at it in the years that it existed, it was not a single actionable case that came out of all that time, energy and effort. It you boil it down between the Good Community outreach officer saying who is who in the community, and maybe a guy saying where the restaurants and stores were did it become more of a distraction than it was worth . I think if you look at the period of time moving forward from september 11th up to the Boston Marathon bombing, you see 500 prosecutions or investigations that led to arrests involving terrorists. You also see out of some of those cases, about 50 of them, if they shoot someone, blow something up, 15 of them were targeted against new york city. Some of them we were lucky, if you look at shazad, he drives a truck into new york city, and despite the fact he had a mistake in his execution in the chemical makeup of the bomb, we would be having a very different conversation. The flip side of that coin is that you risk becoming a victim of your own success. If you go a decade without a 9 11 type attack, you have a Boston Marathon bombing, a fort hood, a couple of close calls along the way, people say do we really need all of this . Do we need all of this protection really . And that is where we struggle for a balance every day. Because alqaeda has just published a magazine saying attack new york city. By the way, here is a recipe for a truck bomb. Either the taliban or the Pakistani Taliban published the magazine just last month saying were fighting over here in foreign lands. But those in new york should rise up and do what they can there in terms of violent action. So you know we live every day with the threat. The reality is, theyre going to keep coming. The reality has changed. This is not a threat that is going to end with a peace treaty. That is the reality of our world and it will be the reality of our Childrens World and their children. It is the new era, if you will, and were constantly seeking to evolve to protect against those threats as they morph and multiply and diffuse. And administrations change and leadership changes, but this one is always going to be one of primary focus. And this new report of the alqaeda leader, of course in an audio message on a radical website says that the threat is greater and president obama know s it. In a related air, al shabaab issued a threat saying well blow you up until we finish you off. Coming up later, new developments on flight 370. And well check back with our team in south korea, where there is breaking news, divers inside the sunken ferry. And then coming up next, a news anchor has a panic attack in front of millions of viewers and thought his career was sunk. But led to a discovery. Hi, im jay farner, president of quicken loans.
