americans. surge crews and investigators from the u.s., europe and asia are all working together to try to peace together the clues. today they got several new clues, including a floating object spotted in the gulf of thailand. search boats are on the way to that site right now. meantime malaysian military officials say radar data indicates the plane turned around before vanishing. because of that they are asking to refocus on the smaller circled area on the left. we're also learned more about the tibet bought by two passengers aboard the flight who were traveling on stolen passports. the passports were stolen in thailand. the tickets were apparently bought together. the fbi says it's ready to send atmosphere to asia to help with the investigation. a time from fta and faa are already on the way to the region. joining us by escape from

charlest charleston, south carolina, mary schiavo, an aviation attorney who works for a law firm that sues airlines. describe exactly what this team, u.s. team, ntsb and faa personnel would actually do once they get there. >> it's true they have begun to find parts of the wreckage. one report is a door. if that's true, the most important thing the faa and ntsb will be doing is getting that wreckage in coordination and cooperation with the other countries that are investigating. just from the pieces of wreckage, even a small piece, they can see if there's telltale fittings, if there was an explosion, explosive residue left on the plane, what that wreckage looks like, or if it looks like it was torn apart when the plane had fallen into the ocean. that's going to be important.

the fbi was detached to work on the case, whenever there's a threat of criminal activity, terrorism, certainly there was criminal activity with passports, we have a protocol the fbi takes precedence. you want to catch the criminals first, stop any copy cat activity. that wreckage could hold clues, very important. >> even though it's unclear whether two passengers with the stolen passport, there isn't a direct link made to the disappearance of this plane and the fact they were on it. just the notion of these stolen passports are enough to get the fbi involved? >> absolutely. when using stolen passports, the whole world is now on alert for things such as this, because in the past people remember the plot which was a precursor to 9/11 attacks in united states of america. in that case they did a trial run on philippine airliner,

planted a bomb, used fake passports because the plot was to take 12 airliners out of the sky simultaneously. the fbi is concerned as are other law enforcement agencies around the world to see if this is a precursor to an even larger plot because they fake passport and also using face recognition to see who boarded. >> talking about the u.s. agencies and all they might do. we're talking about planes from 40 different countries. two dozen ships from several countries are all involved. how do all these countries and this arsenal, how do they all communicate and work together? >> well, for example, when they search the sea, they work off a grid. the coast guard developed it years ago. it's a grid that takes into consideration the waves, currents, air, any information they get and they coordinate. they take blocks, squares,

several square miles each and you search in those square mile areas and systematically literally check off the box. you search the ocean through the grid and it's coordinated, closely coordinated because you want to make sure you don't miss anything. also the navy, submersibles will look for black box recorder, data recorder, they give off audible sound, powered by a battery. the battery lasts for about a month. they want to get it before the seawater takes its toll. everyone has a different job. it's systematic how they map out the ocean square by square order grid. >> you talk about looking for that black box, the ping can last about a month. you have to know where to search. do you feel like these several agencies have had enough to try and pin point they saw some

floating debris, that there has been reported oil slix, is that enough to zero in on an area? >> yes. what they do, they backtrack. they see where they find it, track the weather, currents, ocean condition over the last 48 hou hours. the point of impact will have wreckage there but then spread out literally across the ocean floor and ocean. if this was an event that occurred in the sky, inflight breakup, loss of a structural member like wing or tail or explosion from a bomb or fuel tank, et cetera, that would disperse the wreckage widely over the ocean and it could have traveled further. >> malaysian official said the plane may have turned around after takeoff. if that's the case, what does that tell you? >> tells a couple things. the plane was having problems, serious problems, 777.

>> but no distress call. >> right. no distress call. but also the plane itself sends out radio messages, system status reports. those reports go right from the plane right back to malaysia air base. it gives the base the information about the plane. the pilot doesn't even have to do that. the plane does it by itself. like airbus 340 when it went down, the plane itself sent out messages and distress messages. we knew what was happening before we found the black boxes. we don't apparently have those here, so it says whatever was wrong was very bad. >> incredible. 40 planes and two dozen ships from all different countries all playing a significant roll in the disappearance of this plane. mary schiavo, thanks so much. appreciate your expertise. meantime, among those apparatus joining in this, u.s. navy searching for that missing plane as well. this is a surveillance plane taking off from the u.s. base in

okinawa, japan. it has specialized radar equipment with long range search capabilities used in this search and u.s. navy seahawk. u.s. destroyer is also assisting in this massive, very important search. malaysia airlines is now speaking out about the investigation. andrew stephens joining us live from beijing where family members there are awaiting any kind of news as to what happened to their loved ones. andrew, more than half the passengers on that plane are chinese nationals. the families apparently have been staying at a nearby total complex in beijing. what are authorities telling them and what are they saying? >> it's very, very frustrating for the people who are standing by to get any sort of news for loved ones.

malaysia airlines has been very cautious in saying anything at all. in the past hours incremental movements. we've heard there may be suggestions now the plane could have turned around. there are reports vietnamese airport has seen a new piece of what they describe as debris but weren't able to identify it before. so at this stage there's not much more clarity than we know already. malaysians have been holding news briefings. the latest one, listen to the active transport minister. he's keeping a very wide net on it. >> i say from the beginning we're looking at all possibilities. that does not mean we are -- we are not discounting anything when it comes to lives of innocent people.

>> reporter: not discounting anything. clearly everything is still on the table. as far as specific information is concerned, we're just not getting at the moment. neither are the family members of the people who are on board that plane. so that's the frustration. obviously for them first and foremost but also for the authorities just trying to narrow this down, narrow the search down, when, in fact, it seems to be expanding ever more and search area bigger and bigger. >> andrew, interpol released a statement about these stolen passports. what did it say and what are we learning about these mysterious passengers who accompanied these passports? >> reporter: this is a very interesting development what we've heard over the last 12 hours or so. these two passports were stolen two years ago and they were used to buy airline tickets in thailand by two imposters who

got on that plane, we understand, on the way to beijing. the question is how can two stolen pass parts be used when they were clearly on interpol's database as having been stolen. interpol was out today, the actual secretary-general of interpol came out expressing his real concerns this actually happened. i should point out it's not just malaysia where this has been happening. interpol says only a handful of countries regularly check their database to see what the latest is on stolen passports. so this is a glaring security error. it certainly looks like at this stage. interpol, concerned they did also -- should point out way too early to make a connection between stolen passports and the actual what may have happened to the plane, what may have happened. too early to make that connection. certainly this is an angle which

is going to be looked at very closely. >> fascinating. thank you so much. andrew stevens in beijing. now onto health matters affecting millions of families, maybe even yours. a significant breakthrough in the research for predicting if you or a loved one could get alzheimer's disease. estimated 5.2 million americans have alzheimer's, the disease that causes memory loss. moments ago a new study was released on the first blood test that can predict if someone is on the brink of getting it. bring in cedar medical correspondent. this is phenomenal. >> it is. the whole concept is amazing that you can take a healthy person and predict if they will get alzheimer's. university of rochester publish in a prominent journal, so lets take a listen. >> there's no way to predict who will get alzheimer's disease,

whose brains will get the plaques and tangles that destroy concentration and who will be spared. in a first of its kind study, a simple blood test was able to predict who will get alzheimer's. >> this is a really wonderful piece of science, the most significant observation that we've been able to report in my entire scientific career. >> reporter: the researchers looked at the blood of healthy elderly people, checking for ten fatty molecules called lipids. those with lower levels of lipids, were more likely to develop alzheimer's or memory problems that precede alzheimer's. on average the change from healthy to sick took two years. the test was 90% accurate. researchers and alzheimer's association point out more studies need to be done to check and see if this test works. even if all goes well, the test won't be in doctor's offices for several years. so who would want a test to

predict alzheimer's? after all, there's nothing you can do to stop it. dr. federov, a researcher in the study said he would want to know? >> i would want to plan. i would want to work with my family to make sure i attend to issues important to us. >> some people might not want to know they are destined for a devastating disease. >> detecting it is one thing and a potential breakthrough. and does it lead to a possible treatment? >> that's what they are hoping. this is what researchers are so excited about. if you can put together a group of people who you pretty much know are destined to get alzheimer's you can test out prevention on them. lets try this pill, that treatment, does that work. if you have a bunch of people you don't know if they are destined to get it, that's not a good testing group. >> how are you going to find out who is the best candidate or who should take advantage of this. >> if it does come out on the market and walk into your doctor's office, which is still a big if, years away, you'll

have to make a decision, do i want to know this, do i want to know i'm pretty much destined to get alzheimer's. like the doctor in the story said, i want to know. sign me up for planning. others would say, how depressing. i wouldn't be able to live my life to the fullest. >> interesting. >> different people would have different answers. >> glass half full or empty depending on your perspective. thanks for bring thanksgiving to us. don't miss weed 2, dr. sanjay gupta reports on this phenomenon. it appears 10:00 tuesday. world leaders pulling out all the stops trying to settle down the situation in ukraine. is the key figuring out what president putin really up to?

ukraine's interim prime minister will meet with president obama this week as his country scrambles to hold onto crimea. the prime minister has called upcoming vote an illegitimate decision, a vote dividing crimea. russian supporters packed the capital city for a huge rally. president obama ukrainian sources are also demonstrating telling russian forces to get out of crimea. called david cameron and german chancellor angela merkel. according to the government the leaders have a different assessment on what's happening on the ground in ukraine. they do agree the situation needs to be deescalated. with russia denying it has a

military presence in crimea, paris bureau chief and middle east editor, request good to see you. you have written that putin seems to have taken a pause this week on the situation in crimea. so what's the psychology here? >> part to show when he pushes the pause button, he's the guy with the remote control, he's the guy controlling the situation. there's no doubt about that. he's setting the pace of the confrontation. he can step it up or pull it back. we, the west, anyway, is pretty much dancing to his tune at this point. >> putin describing new leadership as lab rats. even though he supported former ukrainian president, he even said that he had no political future left. so is putin trying to come across as the leader looking out for everyone's interest in the region, or is this more a reflection of the diabolical mind games played by a former

kgb man? >> it's definitely a mind game. the purpose of it is so slowly reconstitute a larger russian empire, which, of course, was lost with the breakup of the soviet union. he wants to see a lot of that property back for both strategic regions and nationalistic, egotistical reasons. he wants to see that expanded. he's moved into georgia in 2008. he has now moved into ukraine. we will see if he starts to make feints toward baltic states, especially latvia, and see how far he goes in ukraine. he's calculating everything carefully. when angela merkel says he's living in a world of his own, that's a little misleading. >> what does she mean? >> the narrative he's giving of ukraine and events in crimea, there's no relation to reality

as she understand it. he doesn't care. he's consciously creating his own reality, his own narrative to sell it to some people in the international community but mainly to sell it to the russian people as part of his whole nationalist buildup. he really doesn't care if angela merkel thinks he's in touch with reality or not. he wants that story of crimeans desperate to rejoin rush, people in the ukraine to rejoin russia. he wants that to be the message russian people are hearing and, in fact, those russian speakers in ukraine are hearing. >> meantime interim president meeting with president obama. what can come out of that? >> not much. i think the question is if people are really afraid -- and i think they are -- that putin might try to take big chunks of eastern ukraine. if he did that, maybe roll further along into the center of

the country, all the way across it. but that's doubtful. this is all going to be from the foreseeable future carefully mod lated. remember, we have not seen a shot fired, at least not a shot that hit anybody in this so-called war. >> threats. >> all threaten. all power game, psyching out the opposition. so far putin has done a pretty good job of it. >> christopher dickey. thank you so much. appreciate your time. >> thank you, fredricka. >> meantime overseas, the mystery deepens what happens to the jumbo jet. coming up, nothing is being ruled out including terrorism.

new information on missing malaysia airlines jet. vietnam navy plane spotted an object floating in the sea southwest of vietnam. they are sending boats to check it out closer. plus malaysia has asked thailand navy to search near its border to see if the jumbo jet went gown in the water there. data shows the missing plane may have turned back before vanishing from radar. equally disturbing according to eticket verifying two people on

the plane using stolen passports, appear to have bought their tibet together. the question remains, what happened to malaysian air flight 370. there are other questions. could it have malfunctioned. pilot error? could it be an act of terrorism? peter bergen joining us now. peter, we don't know what happened yet. one of the things alarming is that the two passengers may have boarded with lost or stolen passports and those two plane tickets were purchased together. so in your view was this perhaps just an opportunity for a couple of folks using fake passports, or do you think it's much more disturbing, more sinister than that? >> we don't know. three ways a plane can go down like this. one is mechanical failure we saw that with twa crashing into the

atlantic. there was some discussion whether terrorist brought it down with missiles. an exhaustive investigation determined it was mechanical failure. another way a plane can go down like this is suicide of the pilot. we saw that with egypt air flight 99. again, exaustive investigation in egypt, the pilot committed suicide. the final is terrorism, lockerbie, scotland, killing everybody on board and three on the ground. those are the three ways a plane can just mysteriously drop out of the air. right now stolen pass parts may be in the air of coincidence. it's not really clear why a jihadi group would target a malaysian plane, it's a country with majority muslim population. there's no obvious motive here if it was terrorism.

>> and if terrorism -- it is among things investigated, the fbi on their way there in large fact because of the stolen passports used to board this plane. while we're on the subject of the terror groups, describe for me what are the terror groups in that region even though on the surface it doesn't seem to be there's real motivation to down this kind of jetliner. who or what groups are in that area you can speak of? >> in kuala lumpur where this flight took off, al qaeda had a major summit in the pre9/11 time period. in fact, it was really a planning summit for the 9/11 attack. so al qaeda kept going through this region and al qaeda affiliateed with a larger group which operates in indonesia, philippines, malaysia, singapore. that group of late, fredricka, it has been -- a huge amount of law enforcement pressure in the country i named against this

group and they are pretty dormant. also, that would suggest terrorism is unlikely, because the biggest terrorist group in the region, which has conducted operations against embassies, western embassies, western hotels, you know, is really largely out of business. so that would kind of also mitigate terrorism being involved. >> peter bergen, thank you. we still don't know why this plane went down. we don't know the endpoint of this plane but we know this is one of the scenarios investigators are looking into. thanks so much peter bergen. appreciate it. all right. meantime, new trouble flaring up in ukraine in the middle of a growing political standoff. now journalists in some region are facing attacks.

today russian president vladimir putin made two calls on crisis in ukraine britons prime minister and germany's chancellor. three leaders having a different assessment what's happening in ukraine, they all agree the situation needs to deescalate, comes as a standoff as media outlets facing attacks? >> paramilitaries confiscate equipment from a station. filming across the road a bulgarian journalist suddenly being spotted. within seconds he's pushed to the ground, a gun aimed at his head, his assistant targeted. they take their cameras being fleeing in a van. brazen attack caught on camera but there one be any

investigation. the self-appointed pro pshz government working in concert with government forces cracking down on opposition and dissent. having taken control shut down tv stations in crimea. russian state tv replaced one of them as it tries to tighten its grip on the media, new crimean authority is of grave concern to these people. bracing miserable conditions 200 pro supporters voice opposition to referendum vote, who will decide if crimea breaks away and joins russia. under the circumstances illegal what they are doing, this woman tells me, ukrainian and the international community is not protecting us. in kiev and europe also consider the referendum illegal. the crimean government says

international observers have been invited to oversee the vote but not surprisingly will come from russia. these observers arriving from a crimean checkpoint not welcome. observers in europe blocked from entering crimea. the government want them to investigate russian troops occupying the region. for now at least it doesn't look like they will be going anywhere. cnn on peninsula, ukraine. >> those military observers were blocked yesterday from entering crimea for the third day in a row. joining me from moscow, good to see you. are these crackdown on journalists more of the same, or is there something uniquely different here? >> i really don't know whether it's different. i think it's not a good idea to crack down on journalists.

i would ask the journalist who made that report to ask not only pro-kiev people what they think but pro russian people. there are a lot of more of those in crimea and ukraine because 60% are russian. i would hope for balanced reporting, which i don't see quite frankly on either side of the fence. in russia it's not very objective and it doesn't seem to be very objective in the west. basically cracking down on journalists is something i would not support in any way. >> is it your view that russia is trying to control the message or even pro russian supporters trying to control the message coming out of crimea? >> i don't think so. i think the message is very clear. i think the overwhelming majority of the population of crimea, as i said, 60% ethnic russian want to be part of the russian federation. now, what i hope doesn't happen

is that after the referendum, which certainly will show that, russia will say, okay, fine, we're taking you in. i think that would be a very bad idea. i think it's dangerous. i think it's a precedent that shouldn't be set. but that is going to be the message very clearly. i also think what people seem to forget is that russia is very worried about nato appearing in ukraine. if ukraine goes west, and if it becomes a member of nato, and that's a realistic possibility, then you'll have nato trips on a long part of russia's border. i think one of the ways of avoiding the crisis would be to somehow get an agreement that ukraine would not become a member of nato. that's one thing. the second thing, in the ukrainian constitution of this new government, the russian language would be also admitted as a second official language. i think those two steps would probably defuse the entire situation. >> it's not already the case that most are bilingual knowing

both ukrainian and russian? >> you know, it's like in canada. you have the majority, the vast majorities are english speaking, yet it's bilingual because you have a french population. in finland, the majority are fins but the language is swedish. it's important to know their language is not a second class language. sure they are bilingual. there's a moral and if you will an important psychological role to be played here. it's important for russians to know their language in ukraine is accepted as an official language. >> what's the message you interpret from this conversation between putin and britain prime minister and germany's chancellor today? hopeful? >> i think it shows that president putin is very worried by the situation. i think speculation that he's trying to rebuild the soviet

empire are way off base. i think he understands all too well the necessity of russia having an international relationship with the west. >> he doesn't want to be isolated. so that russia does not want to be isolated? >> no, he does not. no way. no way at all. certainly not. i think he's trying. my hope is that with all the escalation that's going on, i still think that there's a real chance of finding some kind of way out of this very dangerous situation actually? >> very fascinating point of view. vladimir pozner in moscow. thank you very much. back here in the states, in some portions you go outside and you're going to think it's springtime. another winter blast is on the way for some parts. first, a perfect time to hit the slopes, perhaps, in breckenridge, colorado. there are other things to do
