briefly our arc cyst will be talking about the arc cotton of the construction site and good morning. i think marie has provided you with an excellent timeline regarding the burial that was encountered on it's februar february 25th. that tuesday they encountered a human burial and the protocols were in place the construction stopped and we sent a popcorn to the sight it was a human burial and the correspondence sent two investigators to the site and the chief examiner came to the sight. the native american heritage in sacramento was sent and this person is selected from a list of native americans who put their name on the lists and andrew goggling vin is the occur later at the - he's someone we've worked with and we understand his concerns and he understands audio arc colon works and the day after mr. goggling vin was a appointed on webs the day after me met with the pmc team and this construction folks and the l m.d. made his concerns known and agreed to provide recommendations that's his responsibility how the burial needs to be treat and where it needs to be returned. that friday,

and why the yellow arc? it is not a satellite ping, but it is how far the plane could have gone in the time or the fuel to get to beijing, and that is the fuel it should have had or it goes only 480 miles per hour, and as fast as it could go and you multiply it by the number of hours, and that is as far as it could go, but there is so much space up here and not densely populated space either in parts of the upper peninsula here and talk about kathmandu and the top of the world, and the top of the world, and kathmandu, and k-2 and 100 peaks up here that the plane would have had to fly over. down to the south, the other side of this is a little bit more, i would say intense to find a place to try to land this thing, and if you continue the arc all of the way down here, there is not much land, and i heard you ask this question in the break in my ear, jim, but the plane was on one of the spot, and something on red on my map, and the plane was there at 8:11 in the morning, and here, here, here, here, and not here

southern arc.ou also suggested why it would go so long that way, and this is speculation now, but the fact it continues on that southern arc for so long, so many hours, about six and a half hours on that final leg of the flight at the same altitude and all, well we don't know the altitude, i misspoke there. there's not a live pilot doing that, or a pilot, if a pilot took over the cockpit and took the plane on that errant route and did his partner in, he's taken a pill or something, he's incapacitied, because that's flying without any guidance to go for that long. where they found the suspected wreckage is where the plane would have run out of fuel, so that all fits a picture, but again, there's no proof of this. >> and we still have not eliminated, obviously, something catastrophic happening, as well. >> i think that's important, yeah. >> yes, it is. >> in the beginning we were saying, no, no, something must have happened in the cockpit because that's the only way you can explain certain things, bu

now we have two arcs. and if we fly up to the northern arc there is a lot of territory.at 8:11 am it was on that line somewhere or on the bottom of the line down here. if it is down here, jim, there is not any land that i see within landing distance within fuel distance to get to. it is all a matter of how much gas was in that plane. the last ping they had was 8:11. the government says it may have been on the ground. the 7:00 am 11 minutes after may not have been very far from the 11 ping and the plane may not have been moving and that is why they think the plane may be on the ground. >> that arc is a guide but doesn't mean that it is confined to the red lines of that arc. but that is the best guide that they have at this point. airline safety change big time after 9/11. up next we look at the lessons that we learned back then that may help us find flight 370 today. who drove to the control room [ woman ] driverless mode engaged. find parking space. [ woman ] parking space found. [ male announcer ] ...that secured the data that directed the turbines that powered the farm

the arc occurred right next to the wires that powered the flight deck's most crucial equipment.ng off a fire that spread across the cockpit attic, burning through the ceiling. >> the situation as in the final few minutes of flight was catastrophic. the airplane's full of smoke, there is evidence of multiple aluminum that's being rained down overhead. the electrical systems are failing. pneumatic systems are failing. one by one, everything that they need to keep the airplane in flight is failing. and they finally lose control of the airplane and it rolls toward the ocean and accelerates and impacts the ocean at a very high speed. >> in the wake of the swissair 111 crash, the airline industry is forced to re-evaluate their procedures for in-flight fires. flammability testing becomes more rigorous. insulation blankets are manufactured from more flame resistant materials. and the certification and maintenance of wiring becomes more stringent. >> swissair 111 was a watershed event in how pilots deal with in-flight smoke and fire conditions. after that, pilots recognized how quickly t

including the focus of the search arc. news just in that the plane is more likely in that southern arc which would put it off the coast of australia. and there has been a renewed focus by the australians in that extreme southern area this morning. we'll have more on that coming up. >>> but first, ukraine authorizing its forces to shoot after an attack on a military base. they are vowing to keep crimea from leaving that country. the question is, is it too late? could war be looming? you need a permit... to be this awesome. and you...rent from national. because only national lets you choose any car in the aisle... and go. and only national is ranked highest in car rental customer satisfaction by j.d. power.

(vo) meee-ow, business pro. meee-ow. go national. go like a pro. until you're sure you do. bartender: thanks, captain obvious. co: which is what makes using the hotels.com mobile app so useful. i can book a nearby hotel room from wherever i am. or, i could not book a hotel room and put my cellphone back

in the northern arc, the same is really rue. there are air defense radars all along that arc. particularly in india and pakistan. and along the coast of vietnam. so to me, it seems like an unlikely scenario that needs to remain one of the investigative hypotheticals. but i -- i just don't see that happening. >> you have been in aviation and you have been in investigations before. what is the theory that to you at this point makes the most sense? >> regrettably i believe that this was essentially a hostage situation in the aircraft. co-pilot had a history of security breaches in the cockpit which, by the way, is not uncommon in foreign airlines. particularly non-western airlines. it would seem most likely to me that perhaps the aircraft may have been lost over the bay of bengal. although no one really knows. i have to qualify that. >> of course -- no one really knows. that's why we are spending so much time talking about it. anthony roman, thank you so much for your expertise. now you are all caught up on all the latest developments around that still missing plane. if anything

so all of a sudden, we have this arc and we have this arc. big arc. a million square miles, just 100 miles on both sides of the line, to search that area and to search this. alaska, canada and california together. that's only 100 miles. now, this plane could have flown on for a while after 8:11 a.m., so you may have to stretch that to 200 or 300 miles and then you do the multiplication yourself. one more satellite ping off of a different satellite would have made all the difference because once three cross, you know exactly where that plane is and we do not have that. and i'm not sure we're going to get that at all. this is going to be a long, arduous search i'm afraid, jim. >> yeah. one small clue and they need more clues. you have been tracking some of the ship traffic in that area. particularly down in the seven part of the arc in the indian ocean. is that a help to the search because you have a lot of commercial ships. >> that's right. someone is on watch, look for debris. we don't have just one destroyer out there. all of this commercial traffic

but they can't determine is it in the northern arc or southern arc. guess what, this total amount of acreage here involving these two arcs is 2.2 million square miles. 2.2 million square miles. just down here in this area about 1500 miles south west of perth australia, the search zone is about the size we're told of maine. it is a massive search zone right here. they've now broken up these two quadrants if you will, these two lines into seven quadrants each and each quadrant is 160,000 square nautical miles. it means it's highly unlikely they'll pinpoint the location of this plane in any short order. you have this continuing effort now to shift the focus down towards the southern indian ocean. why? because so far all of the countries to the north with one exception, have said they don't believe that this plane crossed over its territorial borders and it was not picked up on radar. however, in the last few hours, the thais believe it may have been picked up on one of their radars, probably early saturday morning. as to why they didn't report it until n

the two arcs, one arc goes that way. they no longer believe that is the operative one. >> one of the reasons from that is they had reporting from every country except ukraine, nobody had any sense of anything coming into their airspace. >> and the one is bengal searched by the interian forces and nothing has been found. the main focus of attention has been down into the southern arc. and this is the vast area that we have been talking about. >> it is overcast and misty. we know the conditions are, they're calling it moderate. that means they weren't able to spot anything. several days ago satellite showed there was debris 1400 miles off the southwest coast of australia. so that is perth. that's perth just about there, just on the coast. there we go. >> it slipped. >> i'll take your word for it. and then we come out into india. so you're talking about this sort of area is where the debris was last seen. >> all right. so let's go with the factors there. if this is where it was, two pieces of debris. >> about 14 miles apart

how did they get this arc? think about this.f you were to yell out into a canyon and have an echo come back, you would know how big the arc was. it's a really simple part of this equation. another part is called the doppler effect. you hear weather people talk about it all the time. in terms of the location on the earth, just for understanding it, imagine the satellite is about 22,000 miles above the earth if you went straight down. if it sent a signal out, a handshake with a plane out back, that would mean that the plane is in a certain area. then, if you did it again and it were further, took longer to get that signal, it would suggest that it was further out somewhere. that's how they established the pattern of the dots right here a. series of signals that they received from the plane suggesting it was somewhere along this arc. they knew it wasn't to the north because, as authorities looked at it, there wasn't a lot of -- there weren't any radar hits out there. plus, the earth is not perfectly round. the signature would have

so that arc crosses that area, and just like an attack on the u.s.rc crossed pakistan and you said, hey, there are groups there that don't like us, and it raises questions. >> but what is in it for the pilots or the hijackers to go there? what is in it? >> well, entering the realm of speculation, and trying to get inside of their heads, but conceivably taking over a plane and use it as a later date for a target or the missile might enter into the calculus, but if the intention is to crash into the ocean, why fly for six or seven hours? you can fly for an hour and do that, but it does raise possibility of a mystery, and that is going to raise many questions, but as we have said, too early to determine what that is, but it is creating theories. >> so good to have you here for the report, jim sciutto. and we will have more reports from malaysia on the latest of the investigation, and why the timing of the last words heard from the cockpit are a central focus of the investigation, and who said those last words? a rogue pilot or a hijacker? 175. our clien

these two different arcs. so considering where the flate may have been landed, 370, may have landed, even crashed. is there a legitimate survival possibility even ten days later? >> ten days can be a long time. the human spirit is an amazing thing and it can endure a lot of difficult things and difficult situations. it is up to those on the ground to assess the situation right up front. take care of casualties. separate the dead and wound. if there are dead, and then start taking action as a survivalist would. take action to extend your period of life. your survivability and chances of being rescued. there is a certain order we do those in. shelter, everyone will need water. especially those injured and start setting up signal fires and ways to search the rescuers, by air accident foot or on the boat. >> let's hope your optimism is right. thank you for joining us on cnn. one of the biggest mysteries ever. a plane and all of its passengers disappeared over michigan. more than six decades later, the crews and th

so there's an arc, and there's an arc. that's how they got those big red lines.e don't know that the plane was stopped when it was here. malaysian government said maybe it was on the ground. if not, it may have been flying that way or this way. this line right here is 1,600 miles long. this arc is 1,600 miles long. let's say 200 miles either side could be the search area. you do that again on the bottom, that's alaska, california, california, california, and texas added together. that's the size of the search area. because we have one line. if we had more than one satellite. if we had more than one ping, it would be easy. we would know it's right there. right in the middle of that square right there. that triangle. triangulation. no doubt about it. we don't have two lines, three lines. we have one. >> that's a real help. the other thing we learned talking to the makers of the flight data recorders and the ping, it doesn't happen unless the plane hits water. if it's on land in the northern part of the arc, that's one sign from the plane you wouldn't get today. so

that that arc was the delineated a point on which the aircraft ended up.o two different things. the aircraft most probably flew in a straight line from its last turning point somewhere over the sea. are we any closer to finding it? i would feel more comfortable about confidence that this is, in fact, where the aircraft ended when they pick up some of the debris off the ocean. but how it got there, it could easily have been -- well, easily, one of the propositions i put forward is that it could be a double pilot incapacitation. that would account for no radio calls and the aircraft continuing on to an area where one cannot imagine anybody deliberately wanted to fly unless they wished to deliberately end the flight in the indian ocean. >> which then leads to another question, how were they incapacitated? was there a fire in the cockpit or did someone overpower them? where do we go from there? >> well, i think a fire is highly unlikely. fires tend to -- when they take hold in an aircraft pretty much everything in an aircraft is flammable so it's unlikely to b

the malaysian government has put these little arcs but your ships are not near the arcs.ou searching a different pattern or are you doing something completely different or do you have other information? >> the two are the northernmost arcs you see goes over land. we are not really flying over land. we do have permission from malaysian to fly over their territory. any time you fly over anyone's land, you need their permission. right now, just up, malaysia. the southern most side, where really no one is down in that area, to be honest, with our p-8, it will get out there, 1,000, maybe 1200, 1400 nautical miles from their base in kuala lumpur. if you look, that only gets you halfway to the bay of bengal. >> correct. >> it is just such a huge area. no one has really even gun to look in that southern most track yet. >> how long will you be out there searching? >> great question. when we started out in the gulf of thailand, it was a very defined boundaries. it had a defined parameter. normally, in the u.s. navy, what we do, the first 72 hours, that's critical to finding people

they've drawn an arc on a map. that is why it's now adding, as i go to the map here and take a look at it, initially we know the route of the plane is, where it lost control, and why they were looking at the malacca strait. now they've added in this whole other area here, which is all up here. that's because they drew those arcs. so if i take out that little area there and we show how the arc went, the arc drew sort of like that. so that's where it's picked up these 15 other land-based countries way up to the north. the problem is just because they know that is now added to the potential place of where the plane may have flown to, it doesn't mean that it's necessarily easier to access because each of those countries has its air space issues. so you can't just have any plane fly over there and start looking down. you have to coordinate this on the political side. but what they do have is satellites, they can take pictures, and those can be analyzed. >> kerry, to that point, that's a question i've had. if a plane fle

connect the dots and because the earth is round, we get two arcs. the jetliner could be anywhere along here, but most like loin this southern track. in fact, two sources tell us the plane most likely went down in the south indian ocean, far west of australia. still, malaysian officials say they are investigating both arcs and have asked countries to their north to provide satellite and radar data. finding the plane and its black boxes remains the highest priority. the cockpit voice recorder, which recycles every two hours, may not have any voices after more than seven hours in the air, unless the recorders were disabled, which a pilot can do. >> the pilot can turn off the cockpit voice recorder, the flight data recorder by pulling circuit breakers. very easy. >> reporter: so tonight, an expansive area. both of these two red track lines which can't be dismissed. but it is here off australia where our sources continue to say that say believe is most likely where flight 370 is. david? >> david kerley with us every step of the way on this. david, thank

you have a huge arc here. now, if you go to the south, they say if it went a southerly trajectory, the minimum amount of fuel would put it -- minimum amount of speed would put it somewhere east of sumatra, the maximum near australian. right now the australians are moving assets and ships and planes into that portion of the indian ocean to look for any signs of the plane. so far nothing has materialized. if something does, however, materialize in that area and if the plane is already crashed somewhere there, it could take some time for it to wash ashore presumably to australia. we don't know where the plane is and don't know the plane is crashed. at the moment that seems to be the lead theory. why? because of all these countries up here to the north said there's no indication whatsoever that the plane crossed over on their radar. they don't show radar paths at all up here. that would tell you that the most logical path for this plane is in fact to the south. if it sounds like it's a lot of guesswork, it is. tha

if this search area is not on the arc, officials have thrown the arc out or discounted it a little bit. southern indian ocean is a very big place. let me show you what we have here. here's the new search area that the australians are using. are we talking all the way down here for the indian search or talking maybe not quite so far through the maldives or down here. we are going to find that out probably in the morning. but you asked richard quest whether this was the biggest event of the day and absolutely, yes. we'll have to see whether it's this far south indian ocean or this far south. >> ted, you said it appears they have somewhat thrown out the southern arc or moved it somewhat. >> five people say they saw a large jumbo jet fly over the maldives. hasn't that been debunked? >> it's been thrown out as inconsistent, but five people saw it. >> we've had the maldives saying that there's no evidence that the plane came down on the maldives or landed there. that doesn't necessarily contradict any eyewitness. i'm not denying or being disrespectful to an eyewitness. but they are tradition

to the south in the ocean which we talked about last time and this arc to the north.ld it go up this way? it would be very difficult. look at all the places it would have to fly through with radar systems that are still there, people there, people taking a look. even if the radar were not a problem, there is this. there are a lot of people living in some of these areas that almost have to pass over on the way. beyond that, they have to pass over the himalayas. this is the biggest mountain range on the planet, hard to pass by day. nearly impossible question stil remains. how does get on the ground. 200 by 200 and vin nobody spot it. that is the enduring mystery here, wolf. and one of the reasons why investigators are looking less seriously in many.ways up the northern route. >> good explanation. tom, thank you. so our business can be on at&t's network for $175 a month? yup. all 5 of you for $175. our clients need a lot of attention. there's unlimited talk and text. we're working deals all day. you get 10 gigabytes of data to share. what about expansion potential? add a

the elt's on these arc are great when they hit the ground or if they hit the water impact, you'll get their satellite ping. but i think we need to start an incentive that puts a floatable emergency locating transmitter on the tail of these aircraft. i think enough of these have gone down and we're wondering what the heck happened. this point forward, it's well overdue. >> joe, what do you make of this? let me go back to what we started at the top of our show. we announced that the australian officials reporting that a civilian aircraft spotted a number of objects in the search area. what do you make of that news? >> it's a huge area and there is a loft debris in it, a lot of stuff in the ocean. i think it's wonderful. now you'll have to backtrack and you'll know when she ran out of fuel. we never did get that emergency locater, the elt never went off on impact. that lends you, did it impact? it should have. if it did, it would have been picked up with an impact. if it made a landing like sully made, it probably wasn't enough g force to initial that. but if they find debris, they need

you have the two arcs that you just showed where the last bit of satellite data came which opens up the search area which is too big for this and the size of 3 million square miles, the size of the united states. that's a problem. they have the plane coming this way. the trouble is, what happened then?

and this arc to the north. how could it go up this way? it could be very difficult. look at all the places it would have to fly through. radar systems are still there. people there, people taking a look. but even in tf the radar were na problem, there is this. there are a lot of people living in some of these areas that they almost certainly have to pass over on the way. beyond that, they have to pass over the himalayas. this is the biggest mountain range on the planet. hard to pass by day, virtually impossible by night for many aircraft out there. and then even if it were to get out into some flat lands and even if it were to find some remote airfield, as so many people have speculated, the question still remains, how does it get on the ground. a plane of this size, 200 by 200, and have nobody spot it. >> well, thanks to tom foreman for that. and we will continue to follow any updates on the missing malaysia airline. first, we will check other headlines. russian president vladimir putin is being hailed as a hero in moscow after announcing that crimea is rejoining ru

that distress call will go out on a huge arc of notice. so it will go out 1215, the distress frequency. every aircraft in the air on 1215 will hear something go out. >> it's all fascinating but still leads to more questions. and hopefully you'll be around to continue to help us understand. colonel kay, great to have you. thank you. appreciate your insight. thank you all. have a great week. turning it over to my colleague, turning it over to my colleague, wolf blitzer. -- captions by vitac -- www.vitac.com >>> hello, i'm wolf blitzer, reporting from washington. an intense day of searching so far comes up empty. we're following the latest developments in the disappears of malaysia airlines flight 370. search planes return to base in australia today after finding no sign of at the brie in the southern indian ocean. improved weather conditions allowed crews to search visually rather than using radar. the search at sea as seen two objects, photographed by a commercial satellite. australia's prime minister today defended the decision to announce

>> the only thing i'd say is that's not on the arc. the arc sounds like hard data.he arc theory are these circles that they have, the ranges of coordinating -- >> satellite detection. >> -- hand shakes andrey dar pings. these are the regions. >> it's the acars and the inmar. >> the one thing that's positive to take away from not finding the debris yet is at least they're ruling out different areas. >> exactly. >> assuming that they're accurate and not just finding it and it's not too deep under the water. >> it could be the wreckage and it sank, we don't know. they have to try to eliminate as much probability as they can. >> colleen, thank you very much. >> thank you. >> very frustrating for the families and those looking on. there are a lot of calculations and a lot of challenges. we understand that better every day. >>> coming up on "new day." this is a cruel wait for word of what happened. the father of an aviation engineer who was on flight 370 is going to talk about how he and others are trying so hard not to lose hope. [ male announcer ] if you can clear a tab

we've seen the southern arc. you come to the conclusion that actually the plaep was traveling faster than first thought up here but a little bit slower, 400 knots or so, coming down into the south indian ocean. when you put those facts together, it inexorably leads them to conclude that the search zone, the crash point, whatever you want to call it, is now here to the north. the plane didn't go as far. >> well, let's talk about that. the terminology used was crash point. also very interesting in this new search zone because the officials overnight as they were briefing says, this area now is where they believe the flight went down. >> yes. if you look at the currents, let's show you the currents on exactly what's been happening and you'll see that the old crash or the old debris area down there, you have very aggressive currents. >> that yellow line there, one of the most powerful currents in the world down there. >> absolutely. but once you get to the new area just about here, you start to see much less. so last

on the northern arc or southern arc. there's been sources from the u.s. government apparently have been promoting the idea it's really on the southern arc. that's really where the consensus has been shifting. there's a big problem with the southern arc which is that it's very difficult to think of a plausible, psychological motive, for flying eight hours, having conducted a rather elaborate evasive maneuver at the start of the flight which i would parenthetically say is another gold standard piece we can go on. flying eight hours for what? why? it's very difficult. so listen. there have been all kinds of crazy theories. and which is crazier? it comes down to judgment. your own gut feeling. >> these are questions all of us are asking. everyone wants answers to. especially the families. jeff weiss, thank you so much for your insights. greg, you are staying with us for the entire hour. hang tight. we will talk to you again in a moment. >>> up next, what possible clues are hidden in those satellite images? we will take a closer look with the help of an expert

so, they can't be 1,000 mile as way looking along that arc. to be close to where that is in order to find it. and now they have 20 days left. >> you want to add to that? >> i think it is the beacon and the pinging and we are down to 30 days. it is 20 days now. and keep in mind. remember flight 592 in may of 1996 went down in the everglades and eyewitnesss said the plane disappeared into the everglades. it went into mud. and it was, they new where it went. the same thing with air pransport 447. they new where it was and still it took two years to get the black boxes. it was 260 foot area. that is it. so at this point we have to use this day to find the pings. when we come back. we'll talk about that when we come right back. >> growing up actress wendy davis thought something was wrong with her. >> i had lelow self-esteem. i had a tough time staying seated in class found the window next to my desk and the things that were happening outside of the classroom far more interest. >> it wasn't until her daughter colby was diagnosed with adhd that she

there's an arc over a lot of land mass on this planet. you've got investigators right now who are used to combing through wreckage. nothing to comb through. this is a difficult question because people are waiting for loved ones right now, but are there going to have to be some hard decisions made in this -- in the coming days and weeks? >> absolutely, lester. there comes a point where you have to really examine the return on investment. there are so many assets out there, so many countries that are participating, this stage of 11 days into this event if you will. because we're not really sure what kind of investigation to call it. accident or intentional act. i think the malaysians have said intentional act. so you have all these technical investigators sitting there waiting to do something. but they can't. there's going to come a point with this search area, so massive, that somebody's going to make a hard decision that they've done what they could with what they've had, and now we're going to have to find a point of calling it off and m

these two arcs they are working, this is the northern arc. it would go up somewhere in here. this is the southern arc that would go somewhere in here. they now know the countries all in this region, most of them anyway, have said there's no evidence that the plane came over their territory. they've checked their radar tapes. they don't see it. which then brings us back to the southern region, down to the southern indian ocean. now australia is moving their assets. they are moving of ships and helicopters and some planes into the indian ocean to search for any signs of the wreckage of that plane. but it's now been ten days as you know. so -- and most, by the way, most u.s. sources we've talked to do not believe that it is up here in the north. they do not see that. that means most likely, according to most experts, the plane headed to the south. headed to the south. the southern indian ocean. this is a vast expanse of ocean down here. 28 million square miles of water. it is huge. and so the challenge now is to see if they can pick knup pieces of debris or wreckage or any signs

they are looking at those arcs and trying to find a runway in those arcs and the closest one that you the southern route would be christmas island. so here's where we are here. here's the last contact we had. here's kuala lumpur. the plane took left. at least we know that. after that, we don't know much. so the christmas island people believe that the plane took a left again and went farther to the south. let me take you down to christmas island because it's a very short flight. it's an hour or two hours away from where they were up here. this would not take very long to get to christmas island. so what were they doing for the other two or three hours that they weren't flying around? which don't know that. and what we really need, don, we need to get our head around this, we need in mar sat to give us the other pings so we can see whether the plane was getting closer or farther away from the satellite so we know whether those arcs are really true. here's the runway right here. it's a mile and a half long run way. the island is not very populated, not very big. i don't know a place tha

but up here, that's our arc, down here, that's our arc, and up here on the northern part from vietnam to the top of the world, we're talking 100 peek, but then up to the plateau where there's very, very few people. now we do a little bit something more sinister. let's continue the line farther and not take it where it would have run out of fuel. let's say there was more fuel in the plane that what was first thought. you can get people to put more water or oil or fuel in your plane if you pay them enough money. there's tyrann. here's baghdad. so this could be another area that they will eventually look at. it's how did it get there undetected by so many other radars. and so many other military installations, that's part of the problem with the northern extent up here. to the south, there's not much else down there other than water. >> that's fascinating how you show how big of a slice of the planet they have to look at. renee, what do we know about the flight path based on the information we have so far? i know nothing is definitive, but what best guesses are investigators able to make

look at the arc there. reuters is reporting that kazakhstan says it did not detect any unsanctioned use of its air space the day the plane disappear. 26 nations are aiding in this search. >> that search plays out on land and sea and under the water. investigators are intensifying their focus on the pilot and co-pilot. >> malaysia's prime minister has said, somebody deliberately s r steered the plane off course. john lucic is here with us. there is flipping and flopping and this claim being made. it gets shot down. where are you today at this hour looking at this investigation? >> i think because of all this flipping and flopping, that everybody has been doing, i think the malaysian government is making the right decision in slowing things down before they release the information. by releasing information and having to retract it, it is a very embarrassing situation and really confuses this investigation. >> it has been confused from the beginning. the latest has to do with the timeline of what was switched

this is the hardest thing we've got. >> the plane could be in a 25,000 mile arc. only saying this is the amazing frustration. hold on. we'll come back and we have miles o'brien still to come two weeks into the search. no solid leads. up next the cost search and whether it will end without an answer. the numbers are stunning. we were granted access to the same type of u.s. plane that's going out to search for the missing flight. it's the most hi-tech plane and we'll show it to you. we asked people a question, how much money do you think you'll need when you retire? then we gave each person a ribbon to show how many years that amount might last. i was trying to, like, pull it a little further. [ woman ] got me to 70 years old. i'm going to have to rethink this thing. it's hard to imagine how much we'll need for a retirement that could last 30 years or more. so maybe we need to approach things differently, if we want to be ready for a longer retirement. ♪ if we want to be ready for a longer retirement. gundyes!n group is a go. not just a start up. an upstart. gotta g

arc.ials had been saying over the northern arc it would have been over land. it didn't make sense to anyone involved no one would have spotted it. there are many radar stagses along the way. it could have flown until 8:00 or 9:00 in the morning there. so it's possible people should have seen such a thing but there weren't any credible roberts of that. so focusing on this southern arc taking it down into the indian ocean now, we know the area they believe they found something. two large pieces of something. that they apparently have reason to believe may be the jet. about 1550 miles south and west of perth, australia. australian prime minister spoke and just busted this out in the middle of a parliament session that satellites have spotted this in the indian ocean. from there, they send a jet over to begin searching the area. it went through this maritime safety authority and management there, john young just had those words for us. they know where it is. in a general sense, they know the s

into the parameters of the southern arc here. here is what's important to remember. not all search areas are created equal. using complex mathematical formulas, the likelihood of the plane flying, they come up with areas like this and this is actual will i actually a moving target. it was furis also furth to ther and also bigger. look at what they are facing. when all of these planes and boats get out there, what they are seeing is a great, big empty slate, difficult to search on. all it takes is a glare passing over the water as a plane searches or a ship searches or something else, a different lighting condition. they can easily miss something in that water. one of the reasons we know this is the area they are most interested in now, because of that whole formula of what makes it most likely for it to be here is the presence of this. this is a 35 billion dolls navy plane called the pa-poseidon. it is the most advanced plane in the world. it is able to cover thousands of square miles in the course of a single flight searching fo

jeff, you were offering a theory saying the southern arc and the northern arc was much narrower than previously learned. mary schiavo, you want to respond to that? >> yes, they also said they had provided coordinates, more exact coordinates where they believed that something happened the day the plane went missing and provided those coordinates two days later to the malaysian authorities and it was close to where they were looking but they knew this two days after the accident. >> arthur rosenberg? >> that would be inconsistent with the theory that jeff is trying to advance here, which takes you to the northern route. i think there's a lot of credence to that. the route over myanmar and bangladesh and nepal, that's an area of substantial interest. >> jeff beatty? >> well, i don't disagree, because early on we were looking at the northern route. i think it just has to stay on the table. >> you don't necessarily agree? >> i still -- the southern route still seems to be the most preferable one. and i'm still looking for the experts to be drilling down on those pings. they're already at

raiders of the lost arc is the final screening tomorrow at 7:00 p.m. the historical theaters were built in the 1960s, and now they are ready to tear it down and redevelop the land. there is some hope. next month the state will consider giving the theater a historical designation. >>> the bike and pedestrian path reopened ahead of scheduled on the bay bridge. it's been closed since last week, having to remove a temporary connector. it now connects two areas. >>> tomorrow we'll get a little bit of a break from the rain but it won't last long. we'll get you up-to-date on what was a one-two punch. the first path this morning here, and now this is on the heels showing rain in a long arc extending from south of sacramento down to monitor these areas. some of the heavier cells are south of livermore. we head south and gilroy will get good rain. for us, it's being ushered along by this low pressure. there is another one on the way. in between system number 1 here and system number 2 here we get a break on sunday. it won't last long. winter snow warnings are po

i don't know if i would rule out the arc part. i would call it a simple turn to get to the airport and now with the new information that was unbelief avable to me that it w updated into their entry point. i mean i have an explanation for that one too. does this update tell you anything knew about the pilot's actions? it had to be the pilot or co-pilot's actions. nepharius i have heard that word so muff. >> yeah, it tells me that the captain was being a captain. the captain does the communications and now it is back to the captain doing the right thing. i believe that all along. i'm open to the nepharius situation. i see the captain getting this airplane under cone troll. >> what is the biggest misconception you have about this mystery now. >> i think the conception that this is anything but an intensional pilot action can be ruled out. i understand why a pilot in a burning plane would want to turn to the nearest airport. we know that this plane was on one of those two arcs. >> that is provided that data is correct and i'm still no

so that's our arc here. this is our arc here. part of one ring of one satellite of one gps ping. only 8:11 p.m. the plane may have still been moving. let's assume it moved another 200 miles this way or this way. this is not a path the plane did not fly that path. it happened to be right there or there or there or there at 8:11. let's say it kept going. this is about 1,500 miles from here to here. 400 miles wide. same story here. that's 2.3 to about a million miles, square miles. you have alaska, california, and a couple of texases in there to look for this plane. >> one reminder to our viewers, you get into all those countries that they're in. there is a lot of competition for the influences there, between militaries and a the love sensitivity about how much information they share. another hurdle. the size and the challenge of all those countries involved. >> look at all the names. this is not the flight path. this is the ping line. all the way through western china. this is about right here where the plane couldn't go any further. it wouldn't have any more fuel and it couldn't g

sign of the missing aircraft. 26 countries are involved in the search operation covering two giant arcs to the north and south of the plane's last known location. the bbc's jonah fisher is at the media center where that confrontation happened. a warning, his report contains flash photography. >> reporter: there's a line of police here. they are effectively protecting the chinese relatives who came here to try to speak to journalists. keeping the media away. let's see if we can get through. excuse me, guys. i'd like to speak to the relatives. why not? why are we not being allowed through? can you tell me? you're live on bbc world. anyone here want to tell us why we can't speak to the relatives? anyone? what did you say, sir? no. you can see here no one wants to explain it to us. we can read between the lines. the chinese came here, they've been kept in a separate hotel from the journalists, they came here to try to speak to journalists, particularly chinese journalists. they have a sign complaining about the way they feel the investigation is going. obviously once word got around that th

they don't know where but somewhere in that arc. let's look at the indian ocean.tinental united states fitting here. that's the kind of area you're talking about, very deep ocean, very remote. a difficult place to search. you have u.s. assets going there now including airplanes precisely because they have greater range than the ships have previously. but this is where you have a whole other dynamic that comes to play, the geopolitics of this region. more than 14 countries on this path here from southeast asia all the way up to central asia, kazakhstan, tajikistan, tibet a, a dozen countries and rivalries among those as well. why is that important? they don't want to expose their capabilities to each other, their radar capabiliabilitcapab. z countries don't want to show they have too much capability or in fact reveal they have less coverage than their adversaries might have imagined. that's the worry here. yesterday you had the chinese government say to the malaysian government please release more detailed info. the malaysian government is sensitive to china's infl

if we could see where the arcs lay earlier in the flight it's hard to know for sure but it might give a clue as to where this thing is. >> i want to get back to the viewer questions. go ahead. >> on this point, sources close to singapore airlines have told me that they can find no evidence of this. >> the shadows. >> i believe aviation sources also say that they are not look at it. they don't give it any credence. >> good. thank you for that. this one i pose to jeff beatty. we'll talk a little bit more about the satellite season. he says, pakistan confirmed they have nothing in their radar. did we get similar confirmation from all countries on probable route? mr. beatty do you know about that? >> from what i understand we have not heard from anyone yet and we may not get complete information because people are going to be reluctant to share what their true capabilities are. as jim was talking in his lead in. there are people who have had fights with each other in the past. but if i could add one quick thing, don, i see in what mike smith and what jim reported if i'm a family member i

they this might be the southern arc and the northern arc of this travel with the idea that maybe, maybe the plane is somewhere out along one of these arcs. that brings up an interesting point, erin. of the mings the malaysians say they're getting the most help on is analysis of all this data. this isn't just a matter of digging and looking. it's a matter of looking at what you already have and saying does this geb me a clue where to look next. >> how do they decide where to look next, tom or frankly, i guess this is the question, when an area is, quote unquote, done? >> what they're doing basically is a form of do the mathematics it's called baysian theory. baysian theory be basically is a matter of adjusting your probabilities of where something might be based on every new bit of evidence. that's what has led them, for example to, identify this spot about 2,000 miles off the coast of australia. it's not terribly big compared to the whole search area but it's getting a lot of the attention right now because they put in all this information about the probability that the plane headed sou

going south and gives an arc going north. there's other bits of data. the frequency modulation of that wave has allowed the analysts to go and look at data on other aircraft that have been in the northern sector. and what it does is that data that -- the new data, this unique data they found out correlates to aircraft that would have gone south, and not to data mapped off other aircraft that have gone north. now, that tells us, it's gone south. it doesn't tell us how far it's gone south. the assumption they then used is the endurance of the aircraft from the last known transponder ping in the south china sea with the assumption it's gone 450 or 400 knots. and that's how they have been able to come to that area. >> all of that is terrific. if you're a data specialist or scientist or technician, but david, but wrote the book on crash investigations. don't you really need a piece of physical evidence to tell someone your loved one is gone? >> really do. i mean, try to get a handle on it. that's what people want, is a ham on this
