satellite images and this could be another break. a visual spotter on an australian plane reported several small objects floating in that same area. families of the missing 230 239 people on board are frustrated and exhausted and demanding more from authorities. response to that, officials are promising to do more for the desperate families. here's what they had to do. >> we will continue to engage with the families. we are working hard with chinese authorities and the chinese working group to create a more conducive environment for the briefings. i have instructed my team to do a review of both findings so we can improve them. we appeal to all parties to be understanding during the extraordinary and difficult

time. my pledge to all the families is the same. we will do everything in our power it to keep you informed. >> we have teams of reporters covering every angle of the global hunt for flight 370. in malaysia, beijing, perth, austral australia. we want to get you the latest from the ground from perth, australia. sunday morning there, not quite light, three hours from daylight and the start of sunday's search. one question for you, and this is the key. you had the satellite picture showing a big piece, similar size. now a chinese satellite data, similar-sized piece 75 miles away. is the operating theory there that these are the same object? is that a possibility they are considering? >> reporter: certainly it's a possibility. it's certainly something the search crews are going to keep in mind as they head to that area. it was in the search area that the planes were in yesterday, jim, as they were scouring over

this particular area. but they didn't see anything. there was some debris spotted and when they had the military plane come out and look at it, it was first spotted by the civilian plane. they didn't see it, so they have sent a merchant ship out there to try to take a closer look to see what the debris is. but so far, they have found nothing. we are about one hour away from the first planes expected to take off. we are seeing more countries involved now, more planes taking to the air. what the australians are doing is trying to get a larger number of planes into that area to try to whittle down the search area to try to figure out if what these objects are if they are any part of the missing plane, but so far nothing yet. >> i'm glad you noted that that the australians said that the planes up yesterday were in the same area as this new chinese satellite photo. when that happens, do they send search planes back to the area

again just knowing that the seas are constantly moving things around or do they eliminate an area and move on to the next one. >> reporter: they go again and again, especially if they have an intriguing bread crumb like what the chinese sent out. the reason why if you think of the ocean, it's constantly churning. the temperatures are changing, debris moving in and out. especially in this gyre, everything is circling. it's very possible for debris to pop up and then sink back down. it's something that they are constantly paying attention to. especially the spotters. they are going over these areas as more clues pop up. something we should mention, jim s that they are under an extreme time crunch this weekend because bad weather is moving into this ar area. a hurricane warning has been issued in the southern corridor. there's a secondary storm on top of that expected to move in. that's not going to help search

crews that are out there. >> it's a great point. they have a short window of a few days of great weather and now that's going to end. that's a troubling development, but thank you for joining us riets outside the air base in perth, australia. joining me now to discuss the developments, we have cnn aviation analyst himself. a 777 pilot. david susy and also bob bayer, a former cia operative. as we look at this, is this object still likely to be on the surface? the trouble with these satellite images, it takes time to analyze them. you're looking at a lot of pictures. by the time they are released and deploying search teams, it's been a few days. the current is going to move them or it could have sunk. >> your guess is as good as mine. just knowing that the wing structure, to some extent, i would think that a lot of sea

water has gotten into it. . i would be surprised if it's a wing like suggesting that there's a chance that it may be even further submerged at this point in time. >> if it is that, we can go back to the old container theory that it dropped off a ship. >> there's a lot of garbage out there. when you see something in the water, it's not necessarily a plane. there are things floating out there. i wonder if i could ask you, 14 days, two weeks, the air france plane, i believe it was four or five days after it went down that they were able to see some debris. you can remember the picture of the rear stabilizer they found. it's 14 days looking in the ocean. any precedent for searching for a plane for this long without seeing a sign and searching and searching and not finding anything? >> not in this day of modern aircraft, no, not that i'm aware of at all.

but although we didn't have this kind of search capability either. so it is longer than any that's ever been recorded that i've known of. >> bob, a lot of the clues that come through, the first clues are coming from satellite data. there's been some thought, and i think some of it with basis, that you have so many countries down there with difficult, shall we say, relationships and concerns. china, australia, southeast asia about revealing their military capabilities including their satellite capabilities. should we assume these countries are releasing all their best satellite data or running it through a filter because of those security concerns? >> you're exactly right. they are not giving us -- >> you started there, bob, i heard the start of your thought. >> they are very accurate.

they are very accurate, these satellite pictures. but there's no reason the chinese should give us their best quality. they can just point out a location and go there, look there. so we're not seeing the best stuff. >> that's interesting. we could expect the chinese to have studied these pictures though so they had confidence it was worth looking at especially after the false alarm in the south china sea. they would look at their own better view and then release kind of a grainier view to the public. is that an accurate sense of what they might do? >> exactly. they are probably using infrared at this point. if the weather is clear enough, you could read a license plate. it's not very often, but if there was a marking on this wreckage, they would have seen it by now. that doesn't mean they would take the photo and give it to malaysia. they don't want us to know how

good they are. >> a lot of the u.s.'s latest military equipment on display out there as well, including the p.a. we have talked about this a bit, and you said it would be a mistake not to keep looking on land despite this huge deployment now and real focus in the south indian ocean. why is that? >> i firmly believe that. i'm not sure the configuration was, but i'm almost certain that the slide rafts in a ditching situation are provision with emergency locater transmitters. these elts, when they hit salt water, are activated. once they are activated they should send a signal to emergency frequency and a satellite, which would give them latitude and longitude. we don't have that information. >> so when they hit the water, they don't just send a ping in the water you have to listen for with a ship or something or a plane. they would send a signal to a satellite.

>> correct. these new elts, they are designed for a ditching. >> but we don't know this particular plane, that's something e we should look into. >> i'm certain there are other configurations for it, but i'm sure they have slide rafts where in a ditching situation you deploy the raft from the airplane. somebody in the raft will take that velcro piece and drop it. >> you'd have to activate that. >> if it sunk in the water, it would activate. >> that's very interesting. >> that's why i'm thinking if we didn't get that signal, we should still be exploring the land. >> i wanted to ask you a question. if the plane, let's say the plane is in the water because one of the key reasons you need to find the plane is to determine what brought it down. look for signs of an explosion. could salt water, i assume salt water would erode the evidence over time, makes it difficult over time to determine what brought the plane down. is that correct?

>> yeah, definitely does. when you look at the metal, a lot of the keys we find in an aircraft accident have to do with the metal to see if a crack in a particular component had started cracking or fatiguing over time. you'd have a certain wear pattern you could look at through a microscope and see if it was earlier or a sudden tear. it makes a different on the metal itself. so all of that can be -- there's way s ways to get through that, but with salt water it can definitely degrade your ability to do a complete investigation. >> the one key, the one thing that's clear, the longer it takes, the more difficult to answer those questions. thanks to all of you for joining us. still ahead in this hour, what do you tell grieving families whose patience is nearly exhausted after two weeks of dead ends and false hopes. that's right after this break. ♪

in less than an hour, the intense search for flight 370 will start again in one small part of o a giant ocean. in the spot where china says their satellite spotted something. the families of the passengers showing their frustration and lashing out after two weeks already of false leads and deadends and who can blame them. with us is justin green and christine vennson to talk about this, particularly the plight of the families. justin, you have dealt with families who suffered through 9/11 and other aviation disasters. how gutting is it and how traumatizing to go through this without any answers, two weeks now of really just no idea what happened and no closure. >> i mean no one can really know what they are going through until you go through it. the other thing is there's cultural issues of how people deal with grieving. there are common issues.

one of the most common issues is they are not only dealing with the normal sense of loss, but they are doing it in a very public way. 9/11 victims in new york, the families of the victims, every time they went to a store or looked at a newspaper, they get reminded of their loss. here on top of the media frenzy, you have not knowing what happened. and they really can't go on to the next process. i'm sure they are all hoping that something will come out, that this airplane has been taken, their loved ones are alive. until they know what happened, they can't move to the next step. i'm also hearing stories of americans are over there chasing cases and so you have the media going after them, lawyers going after them and they don't have answers. >> not the help they need. families are saying they want media attention because it's ke keeping pressure on the governments. you heard that from some. >> absolutely. i'm talking about the family groups are in these meetings and being chased by pap rarazzi.

>> i hear you. we have seen some of those scenes. it's got to be extremely difficult to handle because you want to suffer that in private, i would imagine. christine, the search teams are under a lot of pressure. they are under pressure from the governments, particularly china, but there also must be self-imposed pressure. they want to serve the families and give them news. it's getting less and less likely it's good news. how does that pressure affect the search crews? >> search crews at this level, these guys are out there for a reason. they know what they are doing. they are just prepared to get in and do their job. at the end of the day -- i'm going to ask you to hold that thought because your microphone is not working. i'm going to ask justin a correct so our viewers can hear you. justin, if i can ask you

watching malaysia airlines handle this, i get frustrated. and i often feel like officials in these situations break very simple rules, which is tell people what you can. and apologize for what you can't say, but you kind of see them clamming up, which increases frustration. what is going on behind closed doors? >> the most important thing is if you're going to release information, make sure it's the right information. don't release information prematurely that you have to back up on later on. that becomes very frustrating to the families. open communication, talking to the families and saying, look, we don't know is communication. not telling them anything, not having meetings. >> it's worse to say nothing. >> especially if the families don't trust you. if you say, look, the akers went

off. >> say a couple words. >> we don't have you back. i'm so sorry. i wonder -- justin, do me a favor. we're going to share resources. this is your microphone hear. we'll do it old school. here's live tv. maybe just hold it as if -- that's perfect. let's go back to the original question. the pressure on the crews. they want to find something. they want to give these families something to help them through their grief, hard answers. how does that pressure affect them? >> these are professionals. these are the best of the best at this point working on these rescue ops and teams. so at the end of the day, they realize that there is potentially loss of life. i don't think you can be conditioned, but they are trained to be sensitive as best they can be working around the conditions they are working under. i know from experience and i know that that is in the back of

their minds at every turn. >> what about the pressure of keeping sharp? i have been looking at some and reading some of the stories about the hunt, hours and hours looking out a plane window. your eyes must go blank. you're look at a blank slate constantly. how do they keep their sharpness up in the midst of a frustrating mission? >> once again, these are professionals, experts and what they do is they rotate them on eight or ten-hour shifts so they don't get overly tired. even so, they are 24/7 ops. so even though they are off after ten hours, it's not like you can turn off and go to sleep. there's still activity. and if they are needed, they are on hand. they are all hands on deck. >> as you say, they are professionals. i think we understand they have their own patch like when soldiers go to war. thank you for joining us.

[ male announcer ] prilosec otc is the number one doctor recommended frequent heartburn medicine for 8 straight years. one pill each morning. 24 hours. zero heartburn. the global hunt for flight 370 may come down to one small sound, the ping from the flight data recorder. the ping may start to fade away about 14 days from now, so crews are racing to find it before

it's too late. here's exactly what that ping sounds like. [ pinging ] rosa flores joins me now. e my reaction, it sounds so quiet and low. i was imagining something louder, higher pitched, easier to hear. the equipment, i suppose, is attuned to listen exactly for that. >> we talked to a company called phoenix international and they told us there's a lot of ways for you to find an aircraft, but a tpl is usually what's used and it does what the name says. so it's a piece of equipment that is equipped with a listening device. it's specifically listening for that ping. and then you have experts on the other end listening for this

pi ping. so what this does is the ping narrows your search. it isolates an area where you know that the wreckage could possibly be, where your debris field could be. then you bring in an auv, or an unmanned vehicle and this is what it looks like, folks, and this is what it does. take a listen. >> reporter: unmanned probes have searched the ocean for plane wreckage before. it took years of sweeping the ocean bottom, but it found a downed plane carrying italian fashion designer, his wife and four others off the coast of venezuela last year. it helped find air france flight 447 after it went missing, locating the wreckage and hundreds of bodies on board. it has found ships that sunk decades ago like the ark royal and the probes even allowed for detailed imaging of the titanic.

>> the smaller ones are only going to down to 5,000 feet. the next is a larger device that's 15 by 25 feet. it's very large because it adds a lot of battery capability and hydraulics capability. >> reporter: the auvs can go as deep as 20,000 feet sending acoustic pulses to the sea floor to find debris and then maps are drawn to guide search teams. they can even find things up to 300 feet under the sea floor. the search zone needs to be narrowed down first. this auv can only search eight square miles a day. it would take four days to search an area as big as manhattan. the equipment works around obstacles so it doesn't get damaged and maps them so divers don't get hurt. >> underwater obstructions are a concern. we fly the auv at a 45-meter altitude above the bottom.

it keeps us out of the way of any obstructions. >> reporter: these types of searches can take months or years but the payoff is high. wreckage that gives clues about what happened, data recorders, and the thing that matters most, the fate of the people on board. >> so the auv narrows your search, it finds the actual wreckage and you step it up with something called an rov, a remote operating vehicle. it's a robot that goes underwater, it has high definition cameras and little hands or claws that would actually help retrieve critical pieces of the wreckage. in this case, of course, those voice data recorders to give us the answers that right now everyone has around the world. >> it's incredible what a success that search has had before for planes on the bottom of the ocean. thanks very much.

to another major story we're following. russian troops today smashed their way into a military air base in crimea. they broke down the gates with armored vehicles and soldiers with rifles at the ready marched on to the base. it's one day since russia formally annexed against the wishes of ukraine's government. russian troops raised their flag over two military bases there today. western observers will be in ukraine in the coming days to keep an eye on the human rights situation there. now nasa is rolling out a new plan to look for missing flight 370. our next guest, an astronaut, says a new space tool in the works may prevent this type of of problem from ever happening again.

a big piece of something, say the chinese, floating in the southern indian ocean is the only thing resembling a clue right now in the disappearance of an airliner with hundreds of people on board. it's not a perfect picture, but chinese officials say one of their satellites took it a few days ago and the white thing might be wreckage from the 777 that vanished more than two weeks ago now. search crews are only now able to get started again as the sun comes up in the south indian ocean scanning the area where the object was spotted. they can only search when there's daylight. the image taken from space. joining me now a man who lived in space for five months as commander of the international space station. he's chris hatfield and author of "an astronaut's guide to life on earth." you have looked down on space from hours to this part of the world from orbit.

help us understand how big and remote a part of that ocean is and also with this question, how well covered or not well covered is that part of the world by satellites? is that something that helps explain why they haven't been able to spot it yet? >> well, the space station is a tremendous place to see the world in a new way. i have spent as much time as i could spare as is the crew up there now with the big cameras looking down at the world trying to understand the surface. that part of the world is not a place we normally photograph because it's stormy, unpopulated ocean. and it tends to all look sort of the same and often it's quite cloudy. so i've looked through the lens there during the daytime. there's a few remote islands there, but mostly it's a vast, really untapped, untraveled expanse. and the immensity of the sea,

sailors know about it, but even people on the space station can see just how large that is. and i know that nasa and the crew on board are looking to see if maybe we're the people that spot something useful down there. >> i want to get to a question i heard from a lot of viewers and i had myself. if you look at something like google earth, you can count the tiles on the roof of my house. now you have these images and they look so grainy and hard to identify. as you said earlier in this broadcast, you can assume that china and other countries releasing these images aren't showing the full clarity. but you also explained it's about the angle of the satellite because they are not right above this area because there's not a lot going on in this area. they are taking these pictures through a lot of atmosphere. explain how that makes a difference. >> well, it's sort of like the difference between the sun when it's just setting and the sun when it's directly overhead.

you get so much more of a sunburn with the midday sun because there's so much less atmosphere as a filter. it even changes color. there's so much atmosphere in the way. a sunrise and a sunset, it's the same effect to try to take a picture either as a crew member on the space station or any of the satellites with cameras looking dieing a normal at the long atmosphere, looking through a puddle or looking across the water. it just messes up the view. and what we want to do is be right above there when there's no cloud in the way and the sun is giving us good light. that's where we want it to take the pictures. that doesn't happen every time. >> i have to ask a question. and i hope this isn't a silly question, but is there a way that the space station could help? i don't know enough to know where that orbit is in relation to that part of the south indian ocean, but are there tools that

could be directed at a patch of ocean like this? >> absolutely. and of course, if you were the crew member on board, just as we were on the station, when there was a volcano, we would do our best to get pictures of that. this is the same thing. we have video cameras staring at the world. there's a company called earth cast that has two cameras staring at the world mounted on a platform and the crew members will be looking with hand held cameras and just recently through a company called planet labs has released 28 remote cameras that are free flying in different orbits all tipped up to be able to look that far south. all of them just looking their best down there. it's unfortunately a huge area, a great big world and it's weather dependent. we're joining in on the effort, but it's not that easy and it's a huge, empty sea to look into.

i shoep somebody e sees something soon. >> it's a fascinating possibility, the idea the space station getting involved in the hunt. nasa has offered their help as well. stick around. coming up, we could have known days ago what happened if it had a device that's already used in some planes. we'll show you that equipment right after this.

welcome back. i'm jim sciutto in new york. much of the information about what happened to malaysia airport 370 is lost along with the plane. even if the plane is found, it could take years for the information to be recovered. but could that be prevented many

the future? here's tech correspondent lawrie seagull. >> reporter: the story of what went wrong vanished. the answers could be in the black box. what if we had those answers all along? >> we would know where the aircraft has gone, where it is, and we would have information on what happened in the meantime. >> reporter: flight makes live streaming data recorders that send information in realtime. it's part of a satellite-based system that monitors the exact location, engine conditions and more. >> the system transmits every five to ten minutes on a normal flight. >> reporter: if something goes wrong like the plane deviating from the route, it streams data. >> that kind of information is not only life saving, but it adds a tremendous measure of security for our country. >> reporter: there are several mechanisms that transmit data, but unlike the systems, the

technology behind flight is more extensive sharing a tremendous amount of information. so much information critics say it could be difficult to monitor and analyze if widely adapt ed. right now technology is only fitted to 350 planes, run by 40 operators. it could be installed for $100,000. normal data transmission carries between a few dollars to $15 per flight hour and goes up for continuous streaming in a rare emergency. >> they are very cost sensitive and will not add safety measures unless mandated by the federal government. >> reporter: as investigators look for high-tech clues into the search for flight 370, the high-tech data record er is getting a second look. >> the technology exists. it's economical and the question now is how do to get more widespread use. >> money tech correspondent lori

seagull joins us now. does it come down to cost? is that why it hasn't happened? >> i asked that question and $10,000 is a lot. it's 1% of what it would cost to run an airplane in general. they are cautious about new technology. this is no small feat. you have to ground the plane for a couple days. it's a relativity new technology. the newest version of this is just been in the market for the last couple years. they are saying they are just now beginning to see a little bit of traction. obviously events like this puts this into focus. >> the other question is how much data is this and would it it overload systems to be sending this constant stream? i suppose you could simplify the data. >> the one thing they will say about the data is they start really doing the live streaming if the plane veers off. >> if there's an issue. >> if there's an issue. also when you think about it, my

question to the guys in flight, if they were able to turn off the transponder, why wouldn't they just be able to turn this off? what they told me is it's difficult to find the kill switch. it's not in the cockpit. they wouldn't tell me where it was, and it also goes into battery power. if there's a big power outage or something t starts running on battery. that's kind of behind the technology. they didn't want to tell me exactly how it could turn off. >> fair enough. i suppose you could say take away the power to turn it off. i have been told by pilots that they need to turn things off in case there's a short circuit. i want to ask you -- sorry, we lost chris hatfield. but we have laurie here to talk about this. if cost isn't an issue, does it sound like -- is it just the size of the task? thousands of planes in the air, it would take a long time? >> it would. and look, everyone is looking at

different types of technology. and there is the idea that let's say that all different commercial airlines were using this type of data. they weren't just using it if the plane veered off. this would be a lot. this could potentially cause satellite interference. and this specific case, they like to say it's not used unless the plane veers off. if this technology were being use liezed by airplanes, this is something o to look at. >> when you have accidents like this, there are fixes that come afterwards. they will have to look at something. a major airliner lost for 14 days. thanks very much to laurie seagull. cnn hero collected hundreds of messages in a bottle in a push to remove 700 million pounds of trash in rivers across the u.s. we'll have his story, after this break.

you don't know where they come from or how they were found. this is cool from the 1993 flood with a flag on it. this is a bunch of lottery tickets, and i don't know if they are winners or not, but obviously not. this is cool. it is a picture of bill clinton. pretty neat. some of them have been found three or four time and then passed on and down the river, and down the river and people sign them an date it. this one had money in it with postage to send it back to them. we haven't done that yet, but we probably should. stamps went up since it was sent though. this is a voodoo one, and it is better not for me, but nails in it with a note and a string tied on it. it is said "you are bound fou." and there is a lot of them that are heavy and written to lost loved one, and you know, i want to keep it because it was meant not to with be kept. it is fun to find them and fun

for the volunteers, but it is a unique collection, because who else finds this many, this h many messages in a bottle. so it is really pretty cool. as the search for flight 370 focuses on a new location, we will take you inside 06 a flight simulator to the show you what could have happened to the plane before it went missing right after this break. i dunno, i just ah woke up today and i said i need something sportier. annnd done. 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. [ giggling ]

again! again! [ giggles ] again! [ mom ] when we're having this much fun, why quit? and new bounty has no quit in it either. it's 2x more absorbent than the leading ordinary brand, and then stays strong, so you can use less. watch how one sheet of new bounty keeps working, while their two sheets just quit. [ bubbles, baby giggling ] again! [ mom ] why use more, when you can use less. new bounty. the no-quit picker-upper. their type 2 diabetes... ...with non-insulin victoza. for a while, i took a pill to lower my blood sugar, but it didn't get me to my goal. so i asked my doctor about victoza. he said victoza works differently than pills, and it comes in a pen. and the needle is thin. victoza is an injectable prescription medicine

that may improve blood sugar in adults with type 2 diabetes when used with diet and exercise. it is not recommended as the first medication to treat diabetes and should not be used in people with type 1 diabetes or diabetic ketoacidosis. victoza has not been studied with mealtime insulin. victoza is not insulin. do not take victoza if you have a personal or family history of medullary thyroid cancer, multiple endocrine neoplasia syndrome type 2, or if you are allergic to victoza or any of its ingredients. symptoms of a serious allergic reaction may include swelling of face, lips, tongue or throat, fainting or dizziness, very rapid heartbeat, problems breathing or swallowing, severe rash or itching. tell your doctor if you get a lump or swelling in your neck. serious side effects may happen in people who take victoza including inflammation of the pancreas (pancreatitis) which may be fatal. stop taking victoza and call your doctor right away if you have signs of pancreatitis, such as severe pain that will not go away in your abdomen or from your abdomen to your back,

with or without vomiting. tell your doctor about all the medicines you take and if you have any medical conditions. taking victoza with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are nausea, diarrhea, and headache. some side effects can lead to dehydration, which may cause kidney problems. if your pill isn't giving you the control you need... ask your doctor about non-insulin victoza. it's covered by most health plans. one possible scenario in the disappearance of flight 370 is that the crew became engrossed in handling an emergency such as a fire in the wheel well or the cargo hold. martin savidge is again in a triple 7 simulator. martin, can you walk us through what would have happened in the

cockpit if the crew was overcome with smoke or fumes or had to handle an emergency like that. >> well, what we will show you is what should happen and then you will know the differences of what we know of 370, and like 370, of course, on the route to beijing and taken off from kuala lumpur and we would have reached that point coming out of kuala lumpur where you turn off of the fasten seat belt, and then the crew would be up here where everybody in the back is relaxing, and then we would get something like that where there is an indication of the problem. that is the alarm. and then a screen readout that says where the fire is located and for this scenario, say in the forward cargo area, and the delegation would be to the captain, and mitch would be now trying to get us down as low as possible, because smoke could come into the cockpit, and we want to be in the place where we can open up the cockpit window

to let the smoke out, and we would have oxygen masks on, and i would be firing here, because this is what is discharging the fire extinguishers in the cargo hol hold, and we would be banking, and this is the turn that is perhaps trying to get back to kuala lumpur or to the airport to try to get this on. and we don't have oxygen masks on which is the simulator here, and we would be communicating, and this is one of the first things that you would do once you have control. >> absolutely for sure. >> and so the only thing that we can think of in this scenario is that perhaps the crew was able to stabilize it at some point. george mitt can chel has been able to do it, and resets now on the new course south the automatic pilot which means that we rare flying straight and level, but in the scenario, we with would have been passed out and nothing else to do, and because it was loaded for the

flight to beijing, this aircraft would have flown straight for seven hours until it ran out of fuel and ran straight into the ocean. >> and martin, the pilots have said that the priority is to stabilize the plane and navigate before they communicate back with the ground. but would there not be any opportunity in there just to make it clear to those on the ground that something was happening or would there even with be an automatic signal to the ground that there is an emergency on board? >> well, both of those could have happened. the acars system if it was working is an alternate communication system that should have signaled these kinds of problems with the aircraft automatically, and the thing is that every time you run the scenario, we cannot understand why there is no radio call. that plane in value jet went down in 7:00, and they had a horrific fire. and the same battery fire in dubai on that u.p.s. plane, they, too, were able to reg

regularly communicate on the radio, and why there is no messaging. >> that is a extremely telling, and really important. >> it is why it says that the fire scenario did not happen. >> and also, because they did not descend rapidly. they had a turn, but no sudden descent, and that is why it seems that it was not a fire by the actions of the aircraft. >> and quickly, did you run through the possibility of a sudden decompression? >> well with, that, it is the same sort of thing, and slam it down on the deck as quickly as possible. another thing to the remember is that the oxygen bottles that you have, and how long do they last? >> on the aircraft, 15 minutes, and about decome prohegs, you are talking about the radio, and navigate before communicate, but it does not happen to navigate and communicate ten minutes

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 invigoratedrc
