inspection. does that change things at all? >> it only adds another piece of the puzzle. it only tells investigators that going in theory there may be a structural problem needs to be run to ground. >> reporter: rene marsh, cnn, washington. >> and thanks so much to all for watching our breaking news coverage continues with anderson cooper. good evening, everyone. we begin tonight with break news. a potential new development in the search for malaysia airlines flight 370. it comes from china which has an especially strong interest in locating the airliner which was carrying so many chinese nationals on board. late today, chinese authorities released satellite photos of what they call a suspected crash site. they were taken on a high definition camera on the morning of march 9th, a day and a night after the the boeing 777 vanished on route from kuala lumpur to beijing. three images in the open ocean, each showing floating objects. what precisely they are, that remains to be seen. we should point out there have been several fault sightings so

far. what is intriguing is the location. according to the chinese it's within a 20 kilometer or 12 1/2 mile radius of this spot on the map which corresponds closely to the point where controllers lost contact with the airliner's radar transponder. we should stress again, this is very preliminary information. however i it may help narrow back down a search effort that grew enormously today. more from pamela brown. >> reporter: these satellite photos released by the chinese punctuate a day of case of and missed messages. five days into the search investigators are still struggling to locate the missing 777, expanding the search area to 27,000 square nautical miles. >> the way forward is to be analyzing both the civilian and military data in the of the the east or west. >> reporter: 12 countries assisting with search

operations. but complicating efforts are a string of confusion and conflicting statements by malaysian authorities. military officials there now appear to be backing off an earlier suggestion that the plane made an abrupt turn to the west less than an hour into the flight. rerecognizance the malay peninsula and ending up in an island in the middle of the malacca strait. other asian officials doubted this theory. then the military offered another theory, saying instead an unidentified blip turned up on military radar 200 miles northwest of the city of panang, close together thai island of puket. >> why possible? we are trying to corroborate. >> reporter: contradictory statements like these have dogged the malaysian response, leading to accusations of incompetence at best or deliberately withholding information at worst. contributing to the confusion, it's still unclear at this point

who's in command of the investigation, the government, the airline or the military. and appearance that none are sharing potentially vital information with each other. foreign powers most vocally china have criticized the seemingly chaotic response and saying their resources are being underutilized. vietnam scaled back its efforts claiming they were provided lack of information on where to search. theories about flight 370's fate continue to swirl. investigators are not ruling out any possibilities, including catastrophic mechanical failure or even terrorism. fears the jet's transponder were deliberately turned off have spawned new concerns about the pilots. police said wednesday they're searching one of the missing pilot's homes outside kuala lumpur. meanwhile, family and friends continue to demand answers and pray for their loved ones, frustrated, angry and unsatisfactoried by the lack of

information. >> when it is not the final closure, i think any ray of hope, even however remote or however improbable, many of these people will still hold onto it. >> reporter: holding on and hoping their days of waiting in limbo will be over soon. pamela brown, cnn, washington. >> a lot to get to tonight now that there seems to be more for searchers to go on. let's check in first with cnn's david mckenzie who joins us from beijing. so these satellite images, what can you tell us about snem do we have my dewhy the chinese government released them now? >> reporter: that's a question i want answered. there are two things that trouble me. one is why this was released now. the second is, really why are we seeing these images that weren't shared necessarily with the malaysian authorities? they say they took these photographs from satellite, high definition of these three large objects which were very close to the tracking path when that plane vanished over the sea on saturday. it is now several days later,

and this appears to be a significant lead, anderson. these are large objects. they call it quote a potential crash site. so it could help narrow the search as you say that is expanded widely in recent days. it gives some level of hope of closure for the many families here in beijing who have lost scores of loved ones. >> the size of the debris has raised some questions from aviation experts we've heard from already who say maybe the debris is actually too large given the size of the aircraft. but the chinese, they seem to have been frustrated with the response by the malaysian government. could the release of these photos somehow be tied to that frustration, forcing the malaysian government's hands somehow? . that's a good point, anderson. they've given very pointed statements toward the malaysian government calling this search sometimes chaotic. they've also criticized the malaysians and other countries for giving out false leads and giving hope to these families here. so it might be that they waited to release this information until they were absolutely sure

it's significant. and we should also believe it's significant because of that. the chinese are much more deliberate with these issues, so they would have carefully looked at these images and thought about what they could be before they released it out. but again because it was several days after they took these images, it's a troubling sign. they have also taken more satellites into that region to look at the whole area to figure out if there's anything that gives any lead to find this plane. certainly significant on the part we believe of the plane when it vanished. so there'll be definitely ships, airplanes, everything going to that area, scouring it from a closer vantage point to see if it indeed is this crashed plane that everyone at this point wants to find, particularly the families here in beijing. >> we're going to talk to a u.s. navy commander who's involved in the search about those satellite images which they are looking at very closely right now. david mckenzie, thanks. more now on the frustration

that we talked about that's been building on the ground as well as the possibility that automated messages from the airliner itself could help locate the plane and make better sense of exactly what went wrong. jim clancy is handling the malaysian end of things from kuala lumpur tonight. jim sciutto is joining us from washington. so jim clancy, another day, no answers more confusion from these differing accounts from malaysian authorities of where the plane might have last been spotted. is there any sense of why things are so inconsistent even at the highest levels? i mean, this public effort by the malaysian government, the public response has just been ridiculous. it's been all over the place. >> reporter: it has been seemingly going in several different directions. the malaysians have been intent on number one exhausting every single lead. you can bet they'll be exhausting the lead they got from china. the chinese ambassador was in the press conference yesterday.

or today. they are going to be looking at everything the chinese have, exhausting all possibilities. and yes, this does give them the sense -- you get impression maybe going in several different directions at once. after all, we are searching hundreds of miles to the west of the crash site. hundreds of miles off the planned flight path of flight 370. so it's obvious why we're getting that impression. that is what is out there. >> and jim clancy, the release of these photos really just adds confusion over where the plane might have last been spotted in terms of the information coming from the malaysian government. yesterday we were hearing reports from some sources in the malaysian government that the plane having made a basically a 180, made a complete turn around. is there any sense of why things are so inconsistent? >> reporter: no, there isn't. nothing absolute. but let me pose something here. if this is so significant, these satellite photos, and you can bet they're going to be checked

out. if it's so significant, why isn't it being reported on chinese state media? yes, the chinese are going to be careful, they're going to try to make sure that these are right before they release them to the international community. but at the same time, they're not reporting it as a headline. they're not raising the hopes of their own people. i think we're just going to have to wait until the cold light of day, anderson, and see what those produce. the malaysian authorities already know they've got a mess on their hands. they've got a lot of fingers in the pie. you see the press conferences. you've got multiple people up there trying to answer different questions. they know they've got to get it right and they're going to try, try to do their best. i've talked with them. they're determined to do that. >> they certainly haven't been getting it right up to now. jim sciutto, we're hearing today word that the engines of the plane transmitted technical data back to malaysian airlines. what are you hearing about this? >> reporter: yet one more confusing conflicting clue in this investigation. the malaysian airlines said the engines were equipped with the

system that sends data at regular points along the course of the trip. an aviation expert told me today that also would be standard on rolls royce engines. there was a report that rolls royce said it did receive two data transmissions, one on takeoff and shortly after takeoff from the engines. nothing abnormal apparently. but rolls royce hasn't confirmed that to cnn. the key then is what happened when the plane lost contact. not just with its transponder but all those other streams of data coming out of the plane. you may remember with the air france flight that disappeared in 2009 over the atlantic ocean, one clue that investigators had even after they lost the plane, transponder, all communications, was they were still getting mechanical updates in effect, fault messages from that plane which were one of the early clues as to what brought it down. to our knowledge, to public knowledge, malaysian authorities don't have any such information from this plane. now why would that be? you'd have to have a catastrophic system failure for the plane not to send anything.

the transponder, the pilot can turn off in the cockpit. that's a safety measure, i'm told, because he has to be able to turn it off in case it was short circuiting and wouldn't bring down other systems. they have that capability to turn it off. the other systems it's not like there's a switch in the cockpit to shut all the other systems off. to get no data from that plane there had to be something catastrophe you can and unusual. but again one of those places where you got a lot of questions but no answers. >> jim clancy, we're now hearing from the director general of the malaysian department of civil aviation. he tells cnn that his agency has not we've not received or even seen these chinese satellite images. how is that possible? >> reporter: it may be a surprise to them. that's a great question. i don't have the answer. because middle of the night here, i don't quite understand why he wouldn't have them. it depends on -- we've got a huge chinese delegation here that would be handling that.

they're liasing very closely. the chinese cambassador was rigt there staring at the generals inside that press conference yesterday. we'll just have to wait and see why that happened. but you can bet going to see think the morning. >> jim clancy, jim sciutto appreciate it. joining us is former inspector general for the u.s. department of transportation, mary sciavo. she currently represents family members of airplane crashes. david, first of all what do you make of these satellite images released by china? this is -- are they too big? i've heard experts say they're simply too big. >> just using my good old algebra, adding those numbers up that's close to the full-length of the plane depending on how you look at it. they do seem awfully large to

me. if they're that large how did they miss them during the aerial search? i am encouraged by the fact that they're close to the last known position. i can't stress how important that is. one of the lessons we learned from air france 447 is that you should always look close to the lkp, last known position. air france wasn't far from that. it was within that 20 kilometer circle. so i'm enthused by that. but if those pieces are that large, which is odd, how could they have been missed in the aerial search unless they sank? how do you do that? >> david, the fact they're so large, you're saying it's possible they're from a plane. that just raises questions about why they were missed. is it possible that that large a chunk of plane would be intact? >> it would surprise me. because air france it was hard to find anything much bigger than a desk. >> really? it broke up that much? >> yeah. pretty much obliterated into smaller pieces. but this is -- those are pretty large chunks of aircraft. it would suggest that if it landed on the water that it

landed in a fairly safe way. it was a fairly gentle landing which brings up a whole another list of questions. >> so i guess we're going to have to see, anderson, in the next couple of hours what's reported. i'm sure ships are on the scene by now and certainly aircraft is out there. so we're going to just have to wait and see. this is one lead we can't ignore so we'll soon find out. >> i talked to a naval commander. we'll have that later on in the program. he said he'll have an update probably in couple of hours as they know more. mary, what do you make of these images? >> i'm actually hopeful they are images. because it would end the wondering and start the work. they do seem large but if the plane came down, there have been a couple of planes that came down on water largely in one piece and broke apart at the water. it's always possible. but the most important thing they can get the naval ships there and get the submersibles and start looking again for the black boxes.

and sometimes the simplest explanation is the explanation. if the plane experienced a catastrophic failure right there this is where it would be. statistically speaking that's often where it is. a failure of the plane and some issue on getting the plane down. and that's where it would be. let's hope that it can start the real hard work and end the wonder. >> david, yet a lot of people said it doesn't seem like it would have been a catastrophic failure or incident at a high altitude if the plane did in fact turn around and fly a fair distance without the transponder on. if it is found in this area, that brings back the possibility of some sort of something catastrophic happening. >> well, in air france 447 it was an issue, a combination of the speed sensors on the outside of the plane and the pilots. so there was -- i wouldn't call that failure catastrophic. and the plane landed within as i said within a very close radius to the last known position.

so again, i don't think we're going have those answers until we either put eyeballs on that fuselage or recover those flight recorders, the black boxes. >> mary? >> and also if this was like an air france scenario, again there was a mechanical problem followed by a pilot error, and what it did is stalled and then it falls to the earth. it's been likened like to a leaf. and that's where it would break up is as it fell to the earth. so it's hopeful. it's possible. and for the families' sake i hope that it is. because every piece of information is just excruciatingly painful for them. i hope this is it for their sake. >> david, what do you make of the communication by malaysian authorities? i mean, i keep thinking about those families. obviously they want any piece of information they can get. but to have such wildly conflicting one arm seemingly not knowing what the other arm is doing. >> it's horrible in case of air france 447 and being inside that

command center, the french were very very careful to bea their version of the ntsb, very careful with the way what was released and the way it was released. i now appreciate that. because these conflicting bits of information and contradictory bits of information can confusion bits of information have got to be tearing them apart. this is a horrible situation for them to be in. >> david gallo,appreciate you being on with us tonight. mary sciavo as well. coming up next we'll talk to one of the american commanders on board a search vessel. latest on what they are doing and how they are holding up. later we've heard about how safe the boeing 777 has been over the years. we'll tell you about a faa bulletin on the plane that is raising some questions tonight. what does an apron have to do with car insurance?

chinese satellite images that may show the wreckage of flight 370. confusion messages about whether the airliner changed course. question now will this new information bring new focus to a search effort that seemed to be getting out of hand? tom foreman takes a look for us tonight. the debris seen in these new satellite images from china, where exactly was it found? >> reporter: you know, anderson, this is why this is like a jigsaw piece that doesn't quite fit the puz puzzle. took off from kuala lumpur. flew up here. disappeared around this spot. the chinese images are about from here or 140, 141 miles away from where the plane disappeared. >> and we've been talk about the massive search area that was expanded today. this is in the original path that the plane took. it is the same general area. >> yeah. the same general area. and if you bring in the currents of the ocean there you could say

that maybe depending on exactly when the photographs were taken the images that maybe it drifted over that way if it would float that long. but again, it's right on the edge of that search area, anderson. that makes it a little bit troubling to say whether or not this is really the right thing. >> the assets being deployed, what are we talking about? what does the search look like? >> reporter: there have been dozens of ships out there, dozens of airplanes out there from a dozen different countries. and they have been scouring an awful lot of territory. certainly some of them will be directed to this area now where the water is about 200 feet deep. but in this process they have to go through an analysis, anderson, the very thing you've been talking about on the show. they have to look at these pieces. and bear in mind not very good satellite imagery but these are really quite large. each one of these pieces if you average them out is about half as big as a basketball court. so the question is, can you get pieces that big out of an airplane like the 777?

the 777 is a very big airplane. no question about that. if you were to walk from one side of the plane to the other on the wings you'd walk about 36 feet from wing tip to wing tip. it's about 200 feet. so is there a way that you could tear this apart and reshape it to make three great big pieces like that? maybe. but like the search area, anderson, it's right on the edge of possibility. and that's what's fuelling a lot of the healthy skepticism right now even as people continue this grim grim business of trying to find out what happened to this plane. >> a lot of the experts we're talking to find it hard to believe the pieces would be that big. but again, so much we don't know. tom, appreciate it. i want to bring in u.s. navy commander william marks on board the uss blue ridge command ship for the united states seventh fleet helping in this search. he joins us by phone. >> commander, you're obviously aware of the satellite images released by china showing possible debris that might not be far from the plane's original

flight path. what do you make of that? >> we are just looking at that right now. it looks from an initial look at the size, if those are as big of chunks that they are in those initial images, it's something that our radars would pretty easily pick up. so we are looking at that right now. we are in plan development at this stage. a couple initial plans, we're loosh looking at where to move our destroyers and looking at bringing in a second search aircraft called a p 8 poseidon into the theater. i can't say we'd get double coverage. we'd probably alternate those flights. but that p 8 is the best technology we have for searching right now. >> these new images of what appears to be debris, we don't know what they are, picked up by the chinese, how will that work?

how close are you to where that debris is? would you start heading there? how would this work? >> yeah. i know everyone's looking at those right now. i think you're the first ones to have them. but us and the navy, we are looking also. i can't give you a definitive plan. but i can tell you everything we do will be coordinated. we will not go off riding into the sunset on our own. it's very well-coordinated. and if a u.s. navy asset is the best to search there, we'll do it. but if another country's assets are, then we'll let them do it. so it's not just the u.s. navy here trying to do our own thing. it's very well-coordinated and integrated. >> in terms of the area where this debris, i know you said you're just starting to look at this area, do you have a sense of how deep the water is there? >> overall, it's not a very deep area. it's relatively shallow water

throughout the gulf of thailand. so i don't know exactly where it is, but overall this is not very deep water. i'm actually watching cnn to try to get a better view of where this thing is. >> so you're actually watching cnn to look at those images to try to get a better view of them, to find out exactly where they are. >> that's correct. but i should say we have very smart people here. so myself just being the spokesperson, i personally am looking at chooat cnn. but we have other people reviewing all the information. >> commander marks, a lot of people appreciate very much what you're doing right now. we wish you the best to all the people under your command as well. thank you. >> thank you. up next, how confusion all this can be. this is one of the satellite images released by the chinese today. coming up we'll show you a photo over the weekend that looks very similar but dismissed by officials. also tonight the families of the miss, seeking answers. we are learning more about those on board the aircraft.

tonight's breaking news about flight 370 is adding confusion. over the past five days we've seen and heard a lot of different images and reports. remember there was this aerial photo that surfaced over the weekend that showed what appeared to be debris off the coast of vietnam.

officials quickly debunked it saying it was not wreckage from flight 370. now look at it side by side with one of china's satellite photos. on the left they were both taken on march 9th. to the untrained eye at least they look pretty similar. though it depends on the distance from which they were taken. joining me professor of aeronautics and as astronaut ex at mit. what do you make of all the back and forth on this. this? >> we don't know but we have to hope that it is. frankly this is the single best clue we've had since this thing began. we've had numerous twists and turns. these pictures were taken a couple of days or 48 hours or so after the incident happened. if you look at the currents in that part of the world they are moving in the right direction. so the difference between the proposed flight plan of the plane and this debris was found does make a certain element of

sense. >> clan jim clancy reported chinese media aren't making much of this. >> other things happening in china that may affect that perspective. we've got nothing else to go on, anderson. this is it. it's either that or some very peculiar reports and rumors of radar pings and tracks that puts it a couple of hundred miles in the opposite direction. >> john, what do you make of these new images? three large objects? >> three large objects but it loo looks skeptical to me. they're too big to be pieces of the airplane. 70 feet by 70 feet across. the fuselage of a 777 is only 20 feet across. so if the size is right, of course maybe the satellite has miscalibrated or something like that. so that makes me skeptical. it's in the right location. everybody wants it to be there. so we've just got to be careful jumping to conclusions.

>> when you say that it's too large, meaning -- we've had other guests say this as well -- -- that the plane would have broken up into smaller pieces if something catastrophic had happened to it or it hit the water at speed? >> there's no piece of airplane that's that big. even if it didn't break up, entire wing was sitting there, fuselage was sitting there it's not that big. because it's square. the fuselage is long and skinny. it's only 20 feet across. the wing is long and skinny, and it's 25, 30 feet across. you don't have anything that's 70 feet by 70 feet. >> john, at this point, where are you on what happened? i don't want to speculate, bull i mean obviously this is the question everybody is -- in your mind have you ruled out somebody? or what are the questions you most want answered? >> okay. everything's on the table right now. because the data that we're getting is pretty crappy. so the radar reports we don't have solid data on. this image doesn't look right, but this is something -- we've

got to track down everything. so we'll get data on this or get better data in this area if indeed and we'll search, if indeed this was part of the airplane or some piece of plastic that unwrapped or something like that, then there will be other pieces and we'll be able to track it down. so it's absolutely a lead to go down. it's the best lead we have right now. but again, people are so desperate for an answer that everybody wants to jump on the next piece of information and say that's it. >> yeah. and richard, there's just been so much confusion coming from ma malaysian authorities. you know this company. you profiled this company. it's got to be for the familis of the people involved in this, it just adds to the horror of it all. >> more than that. it's heart-breaking to see this. what they have failed to do, which is the exact opposite of all other investigations, they have failed to master the fundamental facts and gather them together. the radar track, the air traffic

control chatter, any other chat ter from pilots, the eyewitness reports. instead we've had this leaking, we've had this very odd forms of information being given out. which consequently means we really don't know. and while i fully understand these pieces may be way off beam in terms of size and scope, although the chinese i suspect -- i would question why they would release them in such a fashion. but if they are not, then we're back to square one, anderson. then we are back to square one having no idea where this plane was, no idea which direction it was flying, and no idea where it may have come down. >> it's so bizarre. richard quest, john hansman, thanks. the warning that the faa raised about boeing 777s months before the airplane vanished. calling for frequent inspections on hundreds of planes. the latest on that deadly explosion that levelled two buildings in new york today. you stand behind what you say. around here you don't make excuses.

tonight's breaking news, five days into the search and rescue mission for flight 370, potential key development. chi china released satellite photos of what they suspect is the crash site. three images of open ocean each showing large floating objects. ron brown a pilot for more than 30 years know that is area well. he's flown the kuala lumpur to beijing route countless times and knows boeing 777s inside and

out. you've flown that out, that malaysia airlines was to fly. a, what do you make of these new images, particularly their location? >> first of all you've got to understand those waters aren't clean. there's a lot of trash floating around out there. and it just needs to have an eyeball on it to make sure what it is is what it really is. because anybody can speculate from high above an image. it makes it tough. because the mind is one that tries to see things that it wants to see. >> and a lot of people too have commented on the size of these pieces. are you skeptical that they would have come from a boeing 777? >> yes. first of all, your wing span's about 212 feet. your body's about 209, something of that nature. the tube that you fly in is about 20 feet wide in a round circle. so if it came down and actually the pilot tried to land it in the water, it would be more

intact than just a few square pieces. and you couldn't -- you wouldn't have square pieces. you'd have round pieces and narrow pieces. >> a guest earlier was saying when air france flight was found, there were no pieces really larger than i think a desk he said. i mean, it was in that small pieces. the malaysian air force had said that radar data indicated the plane operating without its transponders on make a u turn toward the ma malacca strait. it's hard to see what radar is picked up alone. >> the transponders are a safety device so that the people on the ground can identify that airplane and know where that airplane is. and the airplane then itself knows where it is besides gps. now, the problem is if they're turned off, it's like somebody turning the lights off. you don't know where that airplane is. and you don't know where it's going. there's backup systems, there's always more than one

transponder. but somebody had to physically turn them off for them to go a different direction and nobody know where they're going if they did go in a different direction. >> you're saying they had to be physically turned off. they couldn't have just broken or malfunctioned. >> no. you have backups. and the 777 has a redundancy all the way around in all the different categories or hydraulics, electrical, pneumatics and so on down the line. so for both of them to be inoperative, all of a sudden, that would be unbelievable. >> i don't want to speculate because i just think there's too much riding on this to do that. but what are the data points that most jump out at you or the things that you want to note most? what are you looking for in the next 24 hours that our viewers can kind of watch for as well? >> well, first of all, common sense means a lot. and i would start out with number one, the aircraft. very dependable aircraft.

been in the industry for over 20 years. did something mechanically go wrong with the aircraft? i seriously doubt it. number two, the pilot and the crew. the pilots and the crew. you had a captain that has 18,000 hours, every six months he's in the simulator practicing emergencies. this wasn't a green horn. you had a first officer over there that either had 18 or 2800 hours. we all start out at zero and we all work our way up. and he was learning. i don't think thought was the pilots that caused that airplane to go down. because other than the egyptian pilot who tried to commit suicide, we haven't had any pilots do that. so the other thing that you look at, the third thing is somebody interfering such as someone trying hijack the airplane or take control of the airplane. to me, i look at that because that makes common sense to me. when the automation of an airplane, when you load up the

flight plan and you're going somewhere, that airplane flies that flight plan unless you tell it to go somewhere else. so somebody had to physically do something to that airplane to make it do other than what it was programmed to do. >> all right. ron, i appreciate your expertise. i'm glad you're on the program tonight. thank you, ron brown. tonight troubling new questions about a possible problem with the boeing 777, the make and model of the jet at the center of the mi mystery. we've heard how safe the 777 is. virtually every expert we've talked to has called it one of safest planes flying today. a faa bulletin on the plane is raising questions tonight. renee marsh has that angle. >> reporter: with more than 1100 boeing 777s worldwide having flown roughly 5 million flights capable of carrying more than 1 billion people, it's considered one of the safest in the sky. but now with the disappearance of malaysia airline flight 370, the plane is under the

microscope. the first 777 rolled off the assembly line in the early 90s. now it's flown by almost every major airline. american has 57, delta 18 and united 74. in its 19-year history, only one fatal crash. the asiana airlines crash in san francisco last july. early indicators point to pilot error. the faa's web site lists more than 100 air worthiness directives for the 777. they alert airlines to potential issues with the plane so they can inspect or repair it. last september, a warning that 777's could have cracks in the top of the plane near an an t a. the faa called for many inspections. >> if everybody read every air worthiness directives they

wouldn't fly because they're frightening but they're not. >> reporter: michael gold goldfarb says if the faa thought it was significant enough they would have grounded the fleet. >> does that mean this air directive and history of this air directive or warning is irrelevant? >> it's very relevant. we don't know if malaysia airline had completed that repair. >> reporter: the ceo couldn't answer if flight 370 was checked for that issue. >> with this specific plane i will have to check on the record. >> let's just say malaysian airlines did not do the required inspection. does that change things at all? >> it only adds another piece of the puzzle. it only tells investigators that going in theory there may be a structural problem needs to be run to ground. >> renee marsh, cnn, washington. we'll have more on the missing flight. learning more about the passengers on board. we'll tell you their stories coming up. also deadly explosion, raging fire cause, chaos in new

but again, back now live to the scene you can see firefighters have changed shifts here about three times. they're still going through this rubble. and they said they're still looking for people. they don't know exactly how many people are in there, but nine people, as many as nine people unaccounted for. on the right of your screen there if you'll look that's the medical examiner's van. earlier they found a body. we saw them pulling a body out. there were two people confirmed dead. now three. we saw them pull that body out. they have been bringing whatever it is they find, and if it's a body into the medical examiner's van that they have set up here on the street and put the body into the van and then taking it away. also earlier there were cars that were parked here. nypd towed those cars away that were on the street. and again, nine people unaccounted for, three people dead so far. and they are still searching for more. anderson. >> don, thanks very much. let's get you caught up on some other stories we're following.

appalling. not where is the plane where where is my mother, my child, my friend? as we continue to cover the investigation we also remember that this is a story about people. the 239 people on board and the countless others who love and miss them. day five of the search and rescue, and still no clear answers on the missing. >> each time that passes i hear that the search and rescue becomes just a search. but we will never give up hope. and this we owe to the families. >> frustration and anger is growing among some of the families. watch as someone throws a water bottle at malaysian airline officials at this private briefing. despite the frustration, some families still hold out hope for their loved ones. rodney and mary burroughs were looking forward to becoming first-time grandparents after their return home to australia. they were traveling with their long-time friends catherine and robert lauden also among the
