later, but it is five seconds, you are on the radio, yes. >> and so very much to martin savidge, and mitchell casado inside of that 777 exploring all of the possibilities that could have happened inside of a real have happened inside of a real cockpit. -- captions by vitac -- www.vitac.com you are in the "cnn newsroom." i'm jim sciutto in new york today for don lemon. we want to welcome the viewers watching around the world on cnn international. we are following the latest search for malaysian airlines flight 370, and following this important story, confrontation in crimea, and armored vehicles crash the gates and take over a crimean military base, and gun fire has erupted. but first, any minute now the invigorated search will begin as

the sun rises over the indian ocean, and the crews will fly from perth australia armed with the clues that have befuddled the world for 16 days now. and new clues could be a break. a spotter on an australian plane reported several small objects floating in the same search area, including a wooden pallet, and this image, a potential piece of the missing jumbo jet. a chinese satellite spotted this object tuesday and it appear s to be long, 74 feet long and 43 feet wide and this new object was spotted possibly 75 miles from the debris that appeared possibly on the australian satellite images seen here. and meanwhile, the families of the missing 239 people on board are frazle, exhausted and demanding more from the malaysian authorities. >> we are here!

>> and responding to that kind of anger, the malaysian officials promised the do more for the desperate families trapped in a heartbreaking wait for answers and waiting in agony now for more than two week, and we can't forget the search for the missing plane on land, and right now, the malaysian authorities are waiting for permission from kazakhstan to stage an area for a search of the northern corridor. we have reporters covering every angle of the hunt for the missing jet in beijing and perth, aus trtralia, and we wano get you the latest. on the ground, we have kyung lah who is live in perth, australia, and we can see the sun coming up behind her there, and it is morning there, and the sun rises and this is the key hour when the jets will be up in the sky, and what kind of a assets will be up there the in the air where

the jet picked up possible debris? >> well, jim, we are inbreak, and it is just now that the military jets should be charging up an launching what will be the fourth day searching off of australia, and heading down about four hours southwest of where i'm standing. and what we are expecting regarding the assets that you are talking about. we are going to have more assets in the air according to the australian government. two planes from china, and two which up with of which we saw landing yesterday at perth international airport arriving from china, and that is going to be joining the australian hunt as well as the new zealand planes, and the civilian plans. on the civilian planes are spotters trained with the naked eye to scan the e sea seas for debris. what they are going to try to do is to whittle down the search area, and check out the seas, and see if the debris spotted is

in fact connected to the missing plane. jim? >> the currents are swirling down there, and is it the working assumption of the searchers that they are looking for the same thing spotted in the two different photographs? >> well, it is a possible. certainly, they don't know. they have the work on the fact that this is another clue. and it is these clues and the best possible lead that we have had since this jetliner simply vanished. it is yet another clushgs and what the search teams are trying to do is to chase this clue as aggressively as possible. if you talk to the people going up into the air, you will sense the same thing that they keep saying that they return without having found anything, they are driven by this desire and hope that they can give the families some answers, because right now, they don't have anything. they want to give that to them.

>> and now they have their own mission patch for the search for flight 370, and all of the folks taking part from so many countries, and thank you, kyung lah, taking part in the search from australia. >> and joining us is a 777 pilot tom fuentes, and assistant analyst and former fbi investigator and faa investigator, and so, steve, if i could start with you, search planes returning to the sky in a few minutes. how can can they make the best of the daylight hours, and the other challenge is that it takes most of the aircraft four hours to get there and then a couple of hours on site and then turn around to come back. how do may make the best time there to maximize the chances of seeing something? >> well, just note at the outset that we are 12 times under way approximately, and this is the time of the year when the days are of equal length. and so if it is daylight in new

york, it is dark there, and vice versa. so i guess that they would take off in the predawn darkness to get there when the light first becomes available. they just, you know, they have to zero in, and we have all looked at the images, and captain aben says that it is too big to be a typical structure, but it is simple as getting a closer look. you know, now if the plane were run so that all of the fuel was out, i might be a little bit more inclined to accept the possibility that it could be the wing of the airplane which would be buoyant and the engine might shear off and be a float iing wing. >> and steve brings up a fair question, a plane hitting the water the at speed is like hitting concrete, and a lot of the pilots have said difficult to imagine a piece that large, and there is a possibility of a

check shup of pieces, and tangled up in wire from the plane or that sort of thing. when you look at the images, do you look at them and say, it is possible that it is part of the plane? >> absolutely it is possible. it depends upon what angle the airplane hit the water and the speed. the interesting thing is that if indeed it is a wing, that fragment, you can start the accident investigation process just by looking at the fragment of where it came off of the fuselage of the plane and how fast it hit the water. >> and also looking for the other signs and soot, and signs of explosion, and test for residue. >> absolutely. >> but you have made the point that the longer that the pieces are in the salt water, the degradation of the evidence? effect. >> yes, of course. >> and tom, iwant to bring you in in, and your experience as the assistant fbi director in a number of investigations, and there is a lot of frustration from the investigation from the beginning, and first of all looking in the wrong place for a long period of time and the sharing of intelligence and

satellite photos and radar tracking information, and that kind of thing, and do you get a sense that the sharing and the organization and the leadership is getting better in the hunt for this plane? >> jim, i sure hope so, but every aspect that you mentioned was really the sharing and coordination between the aviation services, their military, their civil aviation authorities and the technicians looking at the radar data and the satellite data and that is a different matter than the level of law enforcement cooperation that started day one, and working on the case all along with the fbi and the permanent office that is in kuala lumpur, and the agents invited immediately into the command post the very night that the plane disappeared, so that coordination, and cooperation has been ongoing and very, very good. it is just the confusion that is the result of whether it was mechanical failure or pilot or hijacking or the plane flew, you know, thousands of miles or destructed or all of that which is the technical part of the

condition of the aircraft and where it may have gone. >> i'd like to, since we have the international viewers joining us now, invite you the tweet questions to me @jimschiutto, and send your questions our way. and les, if i could come back to you. the world is now focusing on the south indian ocean, and that is where most of the resources are, but they have not given up on the northern corridor over land and you say it is important to keep the focus on the possibility that it ended up on the ground? >> absolutely. just by virtue of the emergency location signals not sending out a frequency just as they will do by satellite and salt water will activate them, and we never got them unless i'm aware that they

were being p monitored and they do send out longitude and latitude. >> and we know that they have asked for permission from kazakhstan, and so we know that the bulk of the resources are though in the indian ocean. we will be coming back to you, i know. and now aside from the debris, searchers are looking for a certain sound. and we will tell you why that sound is so important, and why the investigators need to find it as soon as possible. ok maxwell, just need to ah contact your insurance company with the vin number. oh, i just did it. with my geico app. vin # is up to the loaded. ok well then jerry here will take you through all of the features then. why don't weeeeeeeeeeee go out to the car. ok, i'll just be outside... ok, yeah. his dad is my boss. yeah. vin scanning to add a car. just a tap away on the geico app.

>> reporter: malaysian officials break the monotony of the daily briefings with almost nothing new with this. >> the chinese have received a satellite image of objects in the southeast corridor, and they will be sending out crews to veri verify. >> reporter: this is an object that is not much different from the 24 meter long object released by australian authorities on thursday. the chinese say that the object they spotted is 130 kilometers southwest of the australian sighting, and this is a short distance considering the vast area in the indian ocean. the families have been in agony as they follow every detail, and the emotions are spilling over time and time again. and because nothing has led to

the true whereabouts of the plane carrying their sons, daughters, grandparents and spouses. >> the report went very well, and despite the tension. >> reporter: this is the third satellite image dangled in front of the officials and the families which might have something to do with the missing flight many mh 370 which disappear disappeared more than two weeks ago with 239 passengers and crew aboard. the first one also came from china, and this image of debris released march 13th off of the coast of vietnam, but china said that the pictures were released by mistake, and the search turned up nothing. march 20th, australia said they had found the best lead yet in the search for the missing plane. the australian image sparked a shift in the deployment of military assets and all ships and the aircraft were sent to

the southern indian ocean to hunt down the objects in the pictures and now china is deploying the assets in the middle of a category i cyclone and trying to find the image that matches the satellite images. and still the family hs will have another night of uncertainty to be forced to wait and wonder for a 15th straight night. sara sidner, kuala lumpur. and the search crews have more reasons to be concerned about the passage of time, because emergency electronics to be used to locate the plane will not be lasting forever. and crews are listening desperately for this sound. that's the sound of the pinger, and renee march is our aviation correspondent, and so why does the pinger give a simple tone. and we imagine it to be louder or higher pitched or something, and not just a simple click like that. >> right. and you know, jim, i'm so happy

that we have finally got this audio, because we have been talking about the pingers and the pingers and pingers and finally now we know what we are referring to. and that audio is exactly what the pingers aboard flight 370 would look like if it was detected by underwater technology and normally you can't hear it with the human ear, but the manufacturer helped us to convert it to an audible pi pinger. they are, as you know, associated with the flight recorders, and those flight recorders are so critical, because it will help the investigator to know what happened or what went wrong, and the pingers are attached to the black boxes and likely emitting the sound that is heard, but here is the problem, the battery life on them, probably 50% drained by this point, and when that battery dies around april 6th, the job of finding the so-called data recorders or the black boxes will get extremely

hard. what they use is something called the hydrophone to locate them. they simply drop this equipment down into the water, and so that they can detect that sound that we we just heard within a two-mile radius, and just on friday, the malaysian a authorities said that they need this technology and they have asked the other countries, including the united states to help providing more underwater technology, jim. >> and all right. that is a challenge under the water listening for the pinger. on the surface of the water, you have another challenge, and you know, what do experts say about how long assuming that the plane did hit the ocean, how long wreckage would stay floating on the surface? >> right. so it really depends upon the part of the plane, and there are pieces of the plane in which you would expect this far along more than two weeks now for it to be still on the surface. take a listen to the one expert who kind of flushes out what you would expect to be on the surface this far into the game

here during the search. take a listen. >> most of the cabin furnishings for example were made out of a variety of plastics, and thermoplastics and some composite materials, and things like the overhead bins and the seat cushions, and the kcosmeti bulkheads and all of those typically should be still floating, and in a lot of cases, they will be intermingled with wire and other debris, and so you may have smaller pieces mixed in which might look like a larger piece from a satellite or the air. >> all right. and speaking of those satellite images there, we saw is it. to his point that one satellite image that we saw is roughly 74 feet, and he is saying that, you know, you never know. you have to really get up close to it to know if they are a bunch of small pieces that are very far away to a large piece, a nd we don't know up till we find the actual object float in there. >> and a lot of more planes will be up in the air to get that

closer look. and thank you to you, renee mar march, for that report. >> and russia has crimea under its control, and the tensions and the concerns are growing there. right after this break. what does an apron have to do with car insurance? an apron is hard work. an apron is pride in what you do.

welcome back. i'm jim sciutto in new york, and we will get back to the search

for malaysian airline flight 370, but first, important developments in another part of the world. russian military forces today are taking whatever they want and going wherever they want on the piece of land they now claim belongs to them. this is an air base insooide of crimea, and until today, it was a ukrainian base, now though the russian flag flies over it. the russian troops took over two bases today much in the same way, by force. shortly time ago i spoke with ivan watson. >> we spoke to a commander in the base shortly before the russians made the assault, and he said, listen, we are surrounded by pro russian militia and cossacks and the military units in the back of the civilian groups, and he vowed to fulfill his oath to the

country, to the service, and he said that he would try to use fire hoses to keep the crowd back. well, then what clearly happened according to the security camera footage that was feeding out remarkable live images was that a russian armored personnel carrier bashed down the gates of the air base and then the russian troops stormed in. now, fortunately, there have been no reports of loss of life. instead, what we saw was the humiliating scene of the ukra e ukrainian troops having to bring their flag down and walk out of the barracks with their belongings, and abandoning it to the russian military, and that is a scene that has been playing out again and again, day after day, at different ukrainian military points across the crimean peninsula, as the russian military not only has annexed that entire peninsula, but it is now summarily pushing the ukrainian military out from one base to another. it is really dramatic. there has been one loss of

ukrainian life so far. a soldier who was shot to death while in his guard post in a guard tower. that was a couple of days ago. jim? >> ivan, we have been watching the pictures as you are speaking there of the russian armored personnel carriers, and it looks like the invasion of the military takeover, and i wonder as the discussions continue over gradually escalating the sanctions of russia, and what is the reaction of the people there in kiev and beyond and are they getting the support from europe and the u.s. and do they feel abandoned, but what is their level of concern now? >> it is huge. i have been hearing of the past week talk of war, and we have been watching the ukrainian men of all ages to sign up to be in the reserves or the active duty in the armed forces in the national guard.

the government has called up for 20,000 more troops in the armed forces and another 20,000 in the national guard. i have been hearing the men who were signing up say that i have to protect my country from this enemy, and t he enemy they say almost all of them is russia. >> thank you, ivan watson in kiev. russian president vladimir putin made it official yesterday signing a treaty to formally annexing the crimean p peninsula and making it part of russia. >> and now, what may have happened to the flight 370 that is missing and our aviation experts will shed insights on what the sightings may mean. ♪

chinese officials say that the satellite took it several days ago and the white thing there might be wreckage from the 777 that disappeared a couple of weeks ago. and now, crews will be start the day scanning where the object was spotted and they can of course only search in the daylight. and so today is 15 days since flight 370 took off with 239 people on board for kuala lumpur. and we have cnn aviation correspondent richard quest in the new york studio, and also aviation analyst miles o'brien. miles, if i could start with you, and this is something that we have asked of all of the aviation expert, because there have been doubts expressed in the past about pieces this large being possible of a plane to hit the water, and when you look at the satellite foephotos, to you does it look like a boeing 777?

>> well, if you lay it in one area, and lay it gaiagainst the schematic of a boeing 777, it is hard to know what piece it is. if it is a stabilizer, it is tip to tip, the wing in the back part of the plane or the portion of the main wing section, a nd here we are two weeks later, and this aircraft is almost entirely aluminum, and only 10% carbon materials, and it is hard to imagine a piece of wing still floating two weeks later. and another thing that mitigates against this being a piece of the aircraft is that there is no other notsome nearby, and what you would see is seat cushions by the very least, and maybe the satellite does not allow this, but you don't see anything else in the area, and so i'm a skeptic. >> fair skepticism. richard, are you convince ed

that they are looking in the right place? and remember it was a few days ago when the resources were foe u k kused in the south is, and have you confidence that the best we know puts them in the right place? >> well, you have to go with the evidence that you have got, and it is as slim as it might be, and the truth be told, jim, the pickings are very slim. but in kazakhstan, miramar and india and all of the countries in the northern corridor say they have no radar trace of the plane. and you have searched the immediate area, and it would be perverse to keep searching that northern corridor when you have evidence or potential evidence of what is in the southern corridor, and that is why, yes, you keep an open mind, and yes, you are prepared to go back if there is more further evidence in the northern corridor, but so far, there is no reason to deploy large numbers of assets north. >> incredible that 16 days later, and operating on the best guesses, and typical

investigation? >> well, not really typical. miles might agree with me. >> certainly, atypical to take this long. >> but meaning that it is atypical because you go on the best clues that you have, and no hard answers. >> and so few of them here. and the clues that we do have are tenuous, pings, extremities of science, extrapolation. >> yes, and grainy satellite pictures. miles, i want to bring you in, and this is a question that came through twitter burk, but a fai question. what can commercial airliners do to assure customers that there is not going to be a mh-370 repeat in the future. we don't know the cause of what brought it down, but the difficulty in finding them, and what can the airlines do to make finding a plane like this easier? >> well, there is no financial reason that we don't have constant communication of any

airplane in flight, and telemetry. these aircraft, and there is less known about them than a tractor trailer that drives across this country, and so in this day and age when we are so wired an connected and in fact, as we sit in the back of the aircraft and surfing the web, the idea that this plane isn't tracked, you know, to a very precise level at every moment is actu actually astonishing to most people, and it is a reflection of how the aviation industry works. frankly, a lot of old technology that works, and the aviation industry is reluctant to embrac new technology because of the safety issues, understandable, but it needs to push into the 21st century, and this is a classic example. i think of the poor families wond wondering where their loved ones are, and this is completely avoidable. >> all right. i think that just holding my cell phone here, and i am more track and that plane. >> yes, yes. >> and we had laurie seigel on,

and cnn money correspondent, and she said that it is 1.1% cost of the plane, and so is cost the issue? >> well, it is not the total issue, but it is not an insignificant. an example. it is not the cost of the $100,000, and why do i know that? because they are putting the satellite dishes on the roofs of planes for wi-fi and internet connectivity, and they cost $1 million to install on each aircraft, and if you are a major u.s. carrier, and you have 700 or 800 planes, that is a sizable cost. and the real cost involved is the data. kwo you have to use a data link up up to the satellite, and you will have to have a data stream, and then you are talking about thousands of dollars per month per aircraft. i'm not suggesting for a moment that you put a price on lives, but what i am saying is that the airline industry, miles may agree with me on this, but the

airline industry, and the margins are razor thin, and literally coppers on the ticket. so if you say to the airline, you know, you are going to spend another $6,000 to $10,000 per month for a plane for a full state of stream, then you are going to get the airlines saying, do we need it? how relevant? is it a cost that we want to undertake. >> and the pressure after this they will be required to. that is a debate beginning now. and thank you, richard quest in new york, and miles o'brien in d.c., and we won't let you go. and now as the flight of 370 goes to a new location for searching, we will show you what could have happened to the plane inside of a flight sim yu ulato. this is for you.

one possible scenario this the disappearance of flight 370 is that the crew became engrossed in handling an emergency possibly in the wheel well or the cargo hold. martin savidge is in a simulator cockpit just like the one on this malaysian mh-370 flight. and martin, can you walk us through a scenario where the crew may have been overwhelmed by smoke and fumes and how quickly it would have happened and can you walk us through?

>> yes sh, a broad look at how would have happened, and this is not absolute with 370, but could have. we have set up the simulator to emulate everything that we know about 370, and in other words, up at altitude, and this is the part of the flight where the seat belt sign has been turned off. we have loaded up the fuel the same way they have loaded it up, but the only difference is that it is night time for the purposes of visualization, and we made it daylight. and so up in altitude and everything is going fine when all of the sudden, there would be an alarm in the cabin. it would sound like this. that is the fire alarm, and instantly, you know that we have a serious problem. fire is about the worst thing that can happen on an aircraft. and this is probably the one of the scenarios that the pilots train for most. immediately, mitchell is the captain that we have delegated to fly the plane, and i'm assisting navigating. he is trying to get the plane down on the deck, and while

doing that the alarms are going off and saying that you are descending fast. you want to do get down fast, because you want to open up the windows to get rid of some of the smoke by opening up a window. and then i would have a fire extinguisher in the kcargo hold to suppress the fire, and no word that it would work to put out the fire, and also, we would have oxygen masks, which we cannot deploy, but that is what would be going on. >> and yes. navigate and then communicate. >> yes. and radioing is the last thing, because you have seconds to come back to the ground and you want to alert the airport, we have turned and on the way to the ground with an emergency, and the scenario progresses with the plane stabilizing again, and the plane going on automatic pilot,

and that is what mitchell is simulating and then going ahead to beijing, and then in that process, the smoke overwhelms us, and we are unconscious or incapacitated and the plane with the whole fuel with six hours now has to fly on its own without a single hand to guide it. >> and martin, that is all pl z plausible except for the missing piece, the navigate and communicate, and i nknow that mitch trains pilots, and can you imagine a scenario where that would not be possible? i mean, that it would be incapacitated and not able to communicate, and as mitchell said so that it seems farfetched? >> very farfetched. extremely, and those things would be in quick succession, navigate and communicate, and

without a bullet to the head and they both had heart attacks and you would get into weirder, and weirder scenarios, but in the realm of normalcy, no. >> it is the real red flag of any emergency, because communicating on the radio would be essential and automatic, and the fact that it did not happen and as plausible as the fire theory is, when we run it through the simulator, it does not add up. and it seems that maybe it is more like a cockpit takeover, and if you have a gun to the head why you could not communicate. >> and martin savidge, thank you. and mitchell casado which are familiar surroundings in that 777 simulator. thank you for walking us through it. and now technologies that we didn't know existed. and now what the malaysian government is asking to borrow from the u.s. government.

the crews in the skies and the seas and testing the limits of the technology. joining me now here is technology analyst brett larson. and brett, there is a whole host of countries and host of assets in the ocean, and the air and indeed in space with the satellites, but the malaysians are asking for specific thengs from the u.s., and particularly advanced technology and what are they asking for and why? >> well, one of the things they are asking for from us is a hydrophone which is a microphone which is specifically designed to hear in water and you can't just put a microphone in the water and drop something in there in a waterproof housing, becau because it is not going to hear as well as the hydrophone microphone which is designed to work in the high pressure of the water. >> and to listen for the ping? >> yes. >> and what kind of distance underwater? >> well, we have heard from 5 to 10 miles on that. but that means that they have to be near it, and take into account if it is a part of the ocean that is very deep, and down there at the bottom, that

signal has to go very far. >> and you are talking about the thousands of square miles and you can't drop it in and drive around and that is the importance to find the wreckage which is 16 days later, and then extrapolate as to where the wreckage is to hit the water. >> yes, and working with the ocean currents to keep it moving if it does not sink all of the way. remember with the air france that went down in the ocean, it took them two years to find that black box and in that amount of time it had stopped pinging, and so they had to look for submersibles to find it like we did for the tit"titanic." >> and these are motor operated vehicles, and advanced ones? >> yes, they will need that stuff as this goes into the deeper and deeper parts of the ocean where humans can't send divers down into the ocean to look for that. it would not work out. >> and we had a piece on earlier, rosa flores showing a picture of this, and these things have had success in the past finding lost ships, airplanes, et cetera, and so

they have track record. >> yes, they do. and they have impressive technology on board them that gives them the ability to see underwater with various things. and you know, it is one of the problems that we have been facing over the past couple of weeks with this is that it is in an area of the world that does not necessarily have the best technology at their disposal, and so a lot of it has to be brought in, and of course, as it went from the giant search area to the smaller, it is also dealing with that. >> and one of the frustrations is that you wish that the requests had come in sooner, and then closer to the point when the plane disappeared. >> and that the wreckage would be closer to land so that we didn't have to fly so far or go so far out into the ocean to find it. >> and they are really at the limits of the range here, and right? the plane is going to fly, and four hours on site, and then turn around. and the satellite photos, when they are released including this one today, it is that they say four days ago this was take n ad

why that delay between the photo released and then the assets deployed. >> it is is fascinating the way that the satellites feed the images back to us which is interest interesting, but the interesting part of the next couple of days is that people have the go through the stuff and look at it. there are computer programs that can flag the different things like in this image, you can see that there is a lighter spot in the indian ocean. >> can you put on a setting and say, scan for all things bigger than x-dimensions? >> yes, you will have ships an issues with the clouds, and it is a serious science in finding and looking through the pictures, and then when you see a picture like that, you are talking about an area that is actu actually small. and 90% of the world is covered with ocean, and so when we are looking in the 1,000-square-mile area, it is a lot the look at. >> and the twa flight that crashed, and they knew exactly where it crashed, but he told me the four-mile search area, and

it looked like a dot, and you imagine that dot in thousands of square miles, a it is a challenge. >> and again, dealing with the weather, and all kinds of things even with the satellites. >> thank you, brett larson, walking us through the technology which is going to be so key to find this plane going on. >> and satellite images have sparked hope in the flight of 370, but the task off finding the objects as we have been saying here is going to be daunting. coming up next, we will tell you why this part of the ocean is going to make it tougher on investigators. getting your vegetables every day? when i can.

>> a frsh search for a missing malaysian airline is just beginning after a crew leaving perth, australia, has just taken

off. and they will look in the turbulent indian ocean. and alexandra field is looking at the brutal challenges involved in the search. >> reporter: it is one of the world's most remote and punishing regions. >> it is about the most inaccessible spot that you can imagine on the face of the earth. >> reporter: massive waves and high winds are some of the conditions that have hampered the searchers scampering the south indian ocean searching for flight 370 and its passengers. more than 100 miles off of the coast of australia, the aerial flights can only search for two hours. >> the weather can really hamper any operation. >> reporter: and nasa says that

if the objects seen in three satellite images are parts of the plane, these conditions could push them thousands of feet apart. and oceanographers suggest that the objects, could be in the 15,000 square-mile area which is roughly the size of belgium. and beneath the surface is murkier, because the sea floor sits down 15,000 feet down, and that is more than most submarines can go. and that makes the search more difficult. >> well, the depth and the terrain is a factor. explain what it looks like down there? >> like the rocky mountains. >> reporter: for so many people, it is so difficult to wrap their minds around how difficult this is, and what they are doing. >> if these images are from flight 370, and if the researchers can zero in on the

data recorder, and finding it among the peaks and the valleys could be harder still. >> if it is in one of the deeper challenges, that is one of the larger fields. >> alexandra fields, cnn. you are in the "cnn newsroom" and i'm jim sciutto in new york in for don lemon, and we'd like to welcome the view issers watching around -- viewers watching around the viewers watching around the world on cnn international. -- captions by vitac -- www.vitac.com the p8 poseidon left from perth australia to track several new clues in the missing jet. a spotter on an australian plane reported several small objects yesterday including a wooden pallet floating in the area, and also, a
