How different is this announcement from the malaysian government that they believe the plane was deliberately taken in this direction . Reporter its a hugely significant direction and a Significant Development too. What we know at this stage is the malaysian Prime Minister has finally given some concrete evidence just to say that, yes, the plane did travel in that direction. Yes, we lost contact after about seven hours or so. And there is two trajectories involved. One takes the plane down to the south into the deep southern indian ocean towards the Southern Ocean and one more worringly into the northern region, which does the trajectory, the ark that investigators are looking at does take it over countries like kazakhstan. China, western china, so they are significant areas that is going to be a political effort as well now for the malaysian government. They have to get the governments, all these countries on board. They have to share data. They have to look at the passengers as well. Here in malaysia, i can tell you that soon after the announcement from the Prime Minister that it looks like there was a very, very strong body of evidence to suggest that the plane was deliberately turned away from its flight path by someone on board. The two pilots here, both of the homes of the two pilots, they took away evidence. We dont know what it was in it. I can tell you that the lead pilot, 53yearold, a veteran pilot. He had a simulator, a handbuilt simulator in his house. Thats going to be looked at obviously 37. But at this stage, its all about were hearing theres searches going on at the houses. Nothing more at the moment. Thank you, ann andrew. The Malaysian Authority saying that the flight was deliberately taken over. Another area of interest. Its the newest direction that investigators are focusing on. The possibility based on new information that the boeing 777 was rendered silence on purpose and flown a northwestern route as far as northwestern china. Jim tillman is with me, a 30year captain. Also peterbergen, a National Security analyst. If i can put you on the spot, everything you heard about the transponder timeline, the fuel on board, is this scenario that the plane was common deered and taken to another place . Is that a plausible one knowing what we know now . Its plausible, but like a lot of other things that have been released to us, its a little bit confusing. Lets put it this way. When they communication from the cockpit to the ground, all right, good night, whatever took place, im told this was after the transponder had been turned off. I dont understand that. Because even if it was or not, where was air Traffic Control . The people who were supposed to be monitoring that flight for wherever it goes, why wasnt there some outcry as soon as they lost visual contact with the transponder would have been giving them . Why werent they asking the airplane to squawk i. D. Its just a phrase used by air Traffic Controllers routinely to ask an airplane to punch a button on the transponder and that lights up that airplanes block so that its very obvious to the air Traffic Controller about where it is and what its doing. I havent heard an interview being done with air Traffic Control. After all, these are the people who really are supposed to be monitoring everything that airplane does or fails to do. I want to get back to that point because theres the question of the handoff of the radar and why werent warning signs raised earlier. If i can come to you. Now that you have this ark of flight, if we can put the map up there again so viewers can see it, that takes you possibly to india and far north into those countries of central asia there, it happens that most of the people on the plane were chinese. You also have a restive region. Terror group there is that have carried out attacks recently. A knife attack that killed more than a dozen people. Based on what you know, peter, is it possible that this group couldve the intention of carrying Something Like this out and the ability to do so . Maybe the intention, im pretty sure not the ability based on past performance. Certainly this group has attempted to hijack local chinese flights in china on two occasions, jim. They do have a sort of very small presence in places like afghanistan and western pakistan. But they have been really focused on china. For them to suddenly train someone to fly this kind of sophisticated plane would be an order of magnitude different from the knife attack that you just referenced. So its not impossible, but its also the other thing i think is the separatist group, they tend to be muslim fundamentalist a lot of them, why would they target a Malaysian Airlines, which is after a muslim country, quite a number of muslims on the plane, it doesnt make sense. I think its low probability. Fair question. Let me come back to jim. Theres a practical question. If the plane were to go that far north with developed civilian Aviation Systems as well as a lot of militaries there with a lot of radars, a lot of tensions in this part of the world, you have that question of how it could be possible. You already have one handoff missed from air Traffic Control and the vietnamese did not raise a red flag. How much of a failure do you think that is that a plane of this size could fly through all the radar zones without being detected . First of all, i cant imagine how he could fly that far in that region without being seen by somebodys radar. It it doesnt even make sense. I cant imagine how he could get away with that doing that. That being said, if he was really savvy and really had his homework done, he would know where all those radars were. He would be able to fly at altitudes that would leaf him underneath the radars when necessary. He could pop up later on and fly a little differently. All of that, you have to consider the fact that whatever fuel he had on board, if hes flying underneath radar, hes using a lot more of that fuel per hour than he would at altitude. So i cant discount the seven hours of fuel or whatever else that was available. Lots of problems here. That is a fair point. Youre maneuvering from altitudes, taking turns, that burns more fuel and reduces the range. Peter, that requires a level of sophistication. Again, reminding our viewers were in the realm here of piecing pieces of evidence together for possible scenarios, this is far from hard. You remember before 9 11 americans were amazed, the world was amazed that these hijackers could learn how to fly a jet plane and fly them into buildings. Is it conceivable that a terror group with financing and the commitment and the time could learn to fly a plane and maneuver it in such a way . Its conceivable, but also the malaysian Prime Minister put the notion into play this is a criminal act. A criminal act doesnt mean its a political hijacking. People commandeer planes for strange dlugs delusions. We have seen people take planes to try to get asylum. I know a lot about the radar of pakistan, which is one of the places this plane would have to cross. Because of research i did for the hunt for bin laden. It took the united states, we used helicopters, we flew at night, we flew a map of the earth. Pakistan has a pretty robust radar system just as neighboring countries like pakistan. Its inconceivable, by the way, we have good Radar Systems in afghanistan. One of the busiest airports in the world is kandahar. The idea you could walts a 777 over this year isnt conceivable. Its a smart point because theres so many territorial disputes. The chinese are watching the indians. A lot of resources concentrated there. Great points by both of you. Thank you very much. I know well talk to you again as the search for Malaysia Flight 370 continues and expands. Investigators are now digging for more information on the people on board that flight. Richard quest did a story with the copilot a week before the jet disappeared. Well talk to him about that, next. This is karen and jeremiah. They dont know it yet, but theyre gonna fall in love, get married, have a couple of kids, [ children laughing ] move to the country, and live a long, happy life together where they almost never fight about money. [ dog barks ] because right after they get married, theyll find some financial folks who will talk to them about preparing early for retirement and be able to focus on other things, like each other, which isnt rocket science. Its just common sense. From td ameritrade. Its just common sense. You want a loan to build you cant do that. Ica . Nobody builds factories in the us anymore. You cant do that. Using american Raw Materials makes no sense. You cant do that. You want to hire workers here in the states . Theyre too expensive, you cant do that. Fortunately we didnt listen to the experts. At weathertech we built american factories, we use american Raw Materials and we hire american workers. Weathertech. Com, proudly made in america. Quality like this. You cant do that. Welcome back. Im jim sciutto in new york. The longer it takes to find flight 370 the more the speculation grows, but the part of the world this jet disappears adds to the mystery and the challenges if and when the plane is found. Lets bring in andrew johnson, a geographer at the space museum. Rob is a specialist and expedition leader. One of the things were curious about is has there ever been a search this big for Something Like this . Expanding up to north and central asia, this is enormous area to look for something. At the moment were still bringing in all of the pieces together and trying to ascertain exactly where to start the actual search. At the moments were finding the search box. Were putting all the clues toogt to find where to commence the actual physical search. Just beginning we know we have a lot of assets there, if i could ask your view as well, do you think looking at this that this is something thats manageable in light of the resources that are dedicated . Some 50 ships, very capable. This is a big quarter practically of the planet they are looking at right now. Thats correct. The size of the area is almost hard to imagine for a lot of people and sometimes the more we learn, the larger it gets. I think a lot of people should keep in mind that a lot of the graphics that they see about the possible area, they need to understand the large arks that are shown on the maps dont necessarily show the path of the aircraft. We dont really know the path this aircraft could have taken. Thats the potential area that shows where it was last where we last got data from a satellite. So its truly tremendously huge area and tools like satellite images from satellites are good tools to use, but its going to take a long time to get through the images to identify evidence of where this aircraft may have ended up. Andrew makes a good point. Its the range that kind of half circle we show, maybe we can put up again is the range of places, not the path that it took. Its everywhere inside that half circle there, which is a big cut of land and sea. When you talk about the sea part of this, this is some very deep sections of the ocean. Obviously, makes it much harder. It took years to find the air france flight. How do you manage that . Ships with soern, this kind of thing, how does it work . This is very deep waeter. Anywhere between 4 and 7,000 meters. You search with sound. You tow a sonar unit through the water and you paint the bottom of the sea floor with sound and look for recognizable shapes. We look for hard targets. In this things it would be the leading edges of wings or the engine or the folded up landing gear. So you look for something that small. You picture yourself look iing r a fuse l lodge, but thats probably the first thing to break up. So youre looking for things that stay intact. We look for things that give a good return to the signals were sending out. Its an interesting area that were focusing on now because the sea floor there is relatively flat and relatively similar right throughout. That makes a difference so youre not dealing with underwater mountain skap. Its much simpler pr our point of view. Its been interesting watching all the clues come together. Now were starting to focus in on areas where it may be and perhaps thats why we havent had any clues so far is we have been looking in the wrong area and the clues are in the sea. Thats a big problem, they have been looking in the wrong area. Now they are looking much further to the west. Now that were moving to the west, perhaps well find the debris and that will be the beginning of the start really of defining a search area. If i could ask andrew since you have equal expertise, on land, some advantages if the plane went down or landed somewhere on land, except if you were trying to hide it assuming this remarkable possibility that the plane was commandeered and hidden somewhere or taken somewhere for further use. I imagine the land has its own challenges. Absolutely. We have no idea what happened to the aircraft. And we have lots of possible tools that could be used from imagery from these orbiting satellites to try to identify an aircraft intact or not intact. Honestly, im not surprised that nothing has turned up yet given the size of the area that we have to look through the satellite images. Some of which can identify large things. The majority of satellites in orbit can see things the size of a football field or maybe the size of a city block. There are a few that can identify down to cars or pieces of furniture. But even in those images, the challenges looking through the vast amount of data and its going to take a long time. Im not surprised somebody that has used a lot of satellite that nothing has turned up yet because tough worry about cloud cover, identifying what the objects are. So its going to take quite some time to find some evidence, especially given the everexpanding scope of the potential area. We know a lot of people are contributing now. A lot of countries, the pentagon, for instance, using some civilian satellites to look for this. Thank you very much. Now the timetable of events in the disappearance of flight 370 has changed. New evidence that something was happening inside the cockpit before that last radio transmission. Were talking about that with our aviation expert, right after this. I always say be the man with the plan but with less energy, moodiness, and a low sex drive, i had to do something. I saw my doctor. A blood test showed it was low testosterone, not age. We talked about axiron the only underarm low t treatment that can restore t levels to normal in about two weeks in most men. Axiron is not for use in women or anyone younger than 18 or men with prostate or breast cancer. Women, especially those who are or who may become pregnant, and children should avoid contact where axiron is applied as unexpected signs of puberty in children or changes in body hair or increased acne in women may occur. Report these symptoms to your doctor. Tell your doctor about all medical conditions and medications. Serious side effects could include increased risk of prostate cancer, worsening prostate symptoms, decreased sperm count, ankle, feet or body swelling, enlarged or painful breasts, problems breathing while sleeping and blood clots in the legs. Common side effects include skin redness or irritation where applied, increased red blood cell count, headache, diarrhea, vomiting, and increase in psa. Ask your doctor about axiron. Hey, buddy . Oh, hey, flo. You want to see something cool . Snapshot, from progressive. My Insurance Company told me not to talk to people like you. You always do what they tell you . No. Try it, and see what your good driving can save you. You dont even have to switch. Unless youre scared. Im not scared, its. You know we can still see you. No, you cant. Pretty sure we can. Try snapshot today no pressure. Theres new evidence today that something sinister could have happened on this airplane. Was it hijacked and were the pilots involved . We have a new time line suggesting that the last radio transmission, the words all right, good night seemingly calm and happy were said after the tracking system was switched off. Cnn also learned that police searched the home of the pilot and the copilot, shown here, after the countrys Prime Minister confirmed the plain plaen was likely deliberately diverted. Richard quest here again. So many questions to go over. I wonder if we can ask first to explain to our viewers who might not have heard this yet the significance of the se questing now, the idea that everything was fine and dandy, good night came after one of the systems was turned off. This is not this is straight forwardly from the Prime Ministers statement. And aisle caveat it before, after and in the middle. People are not speaking with the precision of the final report. No question. The Prime Minister says the acars Data Transmission system is switched off or disabled, as the phrase he used, as the plane goes out over the east of malaysia wp. Just as it crosses the land area. The last known point of contact is in the china sea, theres either by transponder or the handoff between malaysia and vietnam. We also know those words were spoeken at that point. We know that because the authorities person said that. Would i be surprised if tomorrow were told that that never happened, i wouldnt be surprised. But on tuesday or wednesday of this week, thats what we were told. And once those words are out there, it was probably a longer senten sentence. It was probably malaysia acknowledging and saying all right, good night. Granted, so many things have changed. We remember the excitement over the satellite photos. But potential significance of this separation of things, it indicates that there was some control or Decision Making s that your view . It indicates, it suggests that at the moment when that last voice transmission was being made there was the incident was already underway. And there is no indication in what was said that we know of that leads one way or the other, but something could have been happening in the aircraft of which they were not aware. Or could have been happening. A fire or something and the system could have gone down. Fair points. Thats the questions it raises. Its given the malaysian government more certainty in the Prime Minister
