jeff, have we reached the limits of our technology. >> the people that did this didn't want to be found. they eluded our technology. >> if someone did in fact want to do it. >> i'm don lemon. that's it for us tonight. ac 360 starts right now. good evening. it is 11 p.m. here on the east coast and 11 a.m. in australia where the flight for flight 370 is running in to problems. it completed a full mission. questions of why there is only one of them in the water only one of them in the water and new questions about the cell phone signals and the aircraft itself. is it even conceivable that the pilot's phone was the only one transmitting or are they holding something back? do they have a plan b? a crucial 24 hours ahead as we have all the angles on that. also tonight, survivors on the sinking ferry in south korea

say they were told to stay put, don't go for the life boats, now hundreds of them are missing, many of them high school students. some of whom sent messages home as the ship went under texting their mothers saying good-bye. the race to see if anyone is still alive. later, with tanks and troops rolling in the country teetering on the brink we will take you to the ukraine and the moves to stop them. we begin with flight 370 and bluefin-21. finding the boeing 777 depends on the bluefin which could be a problem. back from a mission. the first full outing after the first two were cut short. tell us about the third time under the water. >> reporter: yeah, third time is a charm. that is right, anderson, it is back after a first complete mission. you remember the other two missions, the first one cut short because of a failsafe mechanism in the bluefin that told it when it got to 4500

meters to come back up. they fixed that software problem and now it can go as far as 5,000 meters. even a little bit more. the second problem that cut short mission number two was a bit of an oil leak in the bluefin. again, the searchers are not that worried about it. they say it was not that big of a deal. they pulled it up, fixed it. and sent it back down. in all they covered about 35 square miles of the ocean floor down there. and once they have downloaded this latest data and analyzed it, they will send it back down again. >> and in terms of analyzing the data, there is still no information on what they got on this third trip? >> not yet. they tend to release it reasonably quickly. the first two missions they said nothing of significance in the data. now, we'll remember the first time they went down there that is the area they really want to search. and it was cut short because the

bluefin thought it was a little bit too deep for it to go. they told it is okay to go that far down now. they worked out that the depth there is about 4600 meters. so they are going to send it down and go over that area again at some point. because of course, that is where the pings that were most promising were. anderson? >> the oil that they collected near the ocean shield a few days ago that they believe was oil, any word if it is from the plane? >> reporter: not yet word on whether or not it was from the plane. and we do expect to hear shortly, the sounds they got, a thousand miles offshore. what they did was send an australian naval vessel out towards that area until it was close enough for a helicopter to come and land and bring that sample. the ship then came close to the shore until it was close enough

for the helicopter to come ashore. so that has taken a bit of time. it is analyzed as we speak and hope to get information the next few hours. the search from air and sea continues despite being told it would wind down this week. no sign of that happening. tom foreman has been exploring that angle. let's dig deeper in the possibility that in in spite of the glitches with bluefin or because of them it would help to have more. tom foreman is joining us with it. tom? >> the effort above the water has involved dozens of planes and ships going back and forth. why not apply the same thing below the water? we have been talking about how this bluefin will go back and

forth, mowing the grass is the term we have used. why not add another or five or ten or 20 of them? why don't you have them working together because if that's the case couldn't you get it done a lot faster than weeks or even months? not really. here's why. first of all, there's a question of availability. there are only about 100 of these bluefins in the world right now. this one is being used costs about $3.5 million. to get them all assembled you would have to have governments an research organizations and businesses around the world willing to commit these resources for an indefinite period of time. secondly, you would need support for all of these. each one would require a team of experts who know how to program it, operate it, launch it, retrieve it, get the data off of it. bear in mind, this weighs 1700 pounds. just putting it in to the water and retrieving it each time is like putting a small automobile in and out. that's not easy.

last of all, there's the issue we have come back to many times. we talk as if it is a billiard table where these things go back and forth easily. coordinating that is hard enough but the real terrain maybe like this, hills and valleys and all sorts of problems that complicate the ability for these things to coordinate with each other on different planes going up and down and in and out. all of this makes that seemingly good idea maybe one that is completely unworkable. >> thank you very much. there is growing recognition at the current phase, the operation may not last long before they try something different. tony abbott saying as much in a talk to the "wall street journal." we believe the search will be completed in a week or so. if the current search turns up nothing we will move to a different phase. which is a good them to explore with our panel. how the current operation is going and what constitutes a plan "b" if there is one.

former transportation department of transportation mary schavio. and givery thomas is joining us from australia. richard, what the australian prime minister is saying they will regroup and reconsider, what does it mean? >> if you haven't found anything in the area where you were most promising to find something and houston basically said it is around the ping that gave the strongest signal which we now know this evening was the second ping. if you haven't found anything in that vicinity, you have got to really seriously question is it worth keeping going to the first and third and fourth. that's when you have to rethink the strategy. >> give geoffry, you have been talking to your sources there. do you have any insight in to the program -- is there really a

plan "b" here? >> i think there is a very strong conviction where they are looking right now is where the airplane is. that's the undercurrent that i get to the number of people that i speak to on this issue. plan "b," they are talking about if it is deeper than the 4 1/2 thousand meters, significantly deeper they will have to get other submersibles that can go down much deeper. i think there is a very strong conviction that they are looking in the right place. this is the final resting place of the aircraft. i mean, as far as a plan "b" is concerned, other than going deeper, if we need to, i'm not sure what that plan "b" might be. they are pretty certain it's where they are looking. >> geoffry, you are hearing from your sources, and again you have amazing sources there, do you know how confident they are that they know what the terrain is like at this deep? clearly on day one of the

mission with the bluefin-21 it was deeper in a pocket than anticipated. >> look, that's one thing they are confident about. they are confident they don't know what it is like down there. that's why they are talking about a plan "b" that we may have to go much deeper. this area of the indian ocean, my understanding from local ocean olg ographers it is the l explored part of the ocean in the world. it simply hasn't been mapped properly at all. the depths are estimates in many cases. this is probably where the plan "b" comes in. we may have to go much deeper than originally expected. >> it's a good thing for investigators to admit what they don't know. >> sure. i spoke to some colleagues before i came in tonight. there's very little bathometric about the ocean. very little information about

this part. usually there is something to hold on. >> that is so amazing. in this day and age it is often said we know more about the surface of the moon than the depth of the ocean. but it is not completely mapped out. >> we have a general feeling for the big lumps and bumps but where the vehicle is actually living, worried about pinnacles and gullies there's little information. >> is there an effort to do that, a drive to do that. >> oceanographers and scientists have been pushing if ar long time that we need to understand and explore our ocean. we have explored 7% of the ocean. we are living on an unknown planet. >> that is crazy. that's incredible. >> we find the highest mountains, deepest valleys, underwater water falls and we are not getting attention we need to how important this place is. >> amazing to me. mary, what happens in a major operation with like this with

multiple countries involved. i assume it is australia's call to talk about the next phase? >> i assume they would have to do that in conjunction with malaysia. because it is malaysia's investigation to control. i think australia will make a recommendation and malaysia will concur or disagree. theoretically i would imagine they concur with what australia concludes but if the first efforts don't pan out i think they will explore all of the areas of all of the ping s and fan out more. remember, we heard the information about the acoustic tricks of the ocean. that some of these signals can travel a lot further than the three miles or so from the ping. i think they will exhaust all of the pings before they go to plan "b." >> i have asked you this before, david, i keep getting tweets about this. why not have more bluefins in the water? >> to me you have to have the right technology, the bluefin-21

auv, right team, a very talented team and the right plan. the plan they have chosen is they have said okay. we have the pinger. that's the spot. we are going to throw the dart in to the bull's eye close to it. no need to go to a broad area and search using multiple vehicles where you need more people and support to pull that off. it may be plan b but it is too soon in the process to think of that yet. >> that's something houston said when he first announced they were going down. angus houston, the head of the community search organization. he was asked again and again what do you do if you don't find anything? what is plan b? he said we're a long way from that yet. he estimates six weeks to a couple of month s to search the area that they have already identified. so he's not expecting -- i don't know why tony abbott is putting

it in to a weeks, angus houston was talking about six weeks to several months for this investigation. >> president obama's new warning and a showdown with russia. let us know what you think. tweet any questions you have. tough questions about the 370 investigation next. also later a live demonstration of the science of underwater sonar mapping. fascinating technology. the question, are there lessons to be learned from the disappearance of a billionaire aviator steve faucet. the search for his missing plane went wrong because everyone was looking in the wrong place. . also breaking news in the race to find survivors on a sunken ferry. a horrific scene in south korea, very chilly waters. the latest on the sinking and how many people are missing at this point ahead on "36 0." 0."

breaking news a successful third mission for the bluefin sonar submersible. the first successful full submission programmed to go deeper because we have learned the ocean floor is 4 00 meters in the search area, 100 meters deeper than expected and we have learned the search is happening where the second ping was detected, the one detected april 5th at 9:27 p.m.

that ping is the most promising because of its quality is the word they use. details like many others in the search have been coming almost like clock work. we get them from australian authorities. in the search for answers, information has been harder to come by. the item, the co-pilot's cell phone. pamela, what are you learning tonight? >> this is another tiny piece of the puzzle. expert s and sources we have been speaking with are trying to figure out what the information about the co-pilot's cell phone really means. we know that if any of the passengers were on and not in airplane mode they should have dinged the cell phone tower and considering 30% of people forget to turn off their phones according to too to a recent survey it is likely it wasn't just the co-pilot's phone but the phone should have been off. was it turned on before it hit

the cell phone tower after the systems mysteriously shut off? i want to make it clear, sources say there's no indication any calls were placed. just because a phone connects to a cell phone tower doesn't mean a call can go through and it is tough to get the answers and information we need to know what this means. >> any information gleaned about the cell phones could aid the overall investigation. >> yeah, right. it could if certain factors become clear like the co-pilot's phone was off and then turned on after the plane disappeared. to put it in to context, anderson, investigators don't seem to be jumping up and down over the information. they have known about the data detection for a while and it doesn't tell us the critical information we need like a motive and wo was alive on the airplane. this investigation is ongoing in to the passengers and crew. so far, it's not leading to the answers we are looking for here. in many ways, anderson folks are waiting for that black box to provide the rel proof of what

happened on flight 370. everything so far is a small piece of the overall picture. >> pamela, appreciate the reporting. back with our panel. this is probably a dumb question -- maybe david gallo, is there any value in retrieving cell phones from the depth or probably not? >> i have been meaning to check on that. it seems like not but it is part of -- if there are clues to be had it is worth doing. i don't know the answer to that. >> it is interesting the bluefin searched 90 kilometers which is a small area. >> yes. we were warned that was what it with was going to be. it takes it six times as long to search the same area that could be searched in a day by the towed ping locater. that was why they were determined to exhaust the tpl to the last possible second because they knew this was a very slow process. but they do believe they have

narrowed it. the word they used is manageable. it's clearly not desirable but the area they are looking at is manageable, given time, patience and effort. >> david gallo, i hear people refer to the air france investigation which you co-led and using the two-year figure and i used it early on thinking it took two years to find but you have clarified a lot of that was getting permission, convincing people, dealing with bureaucracies, getting permission to go on site. when somedaying searching with vehicles underwater, how long? >> it depends how you count it. we were there total of ten weeks and eight weeks in the wrong haysta haystack. the retro drift led us to a area where there was no aircraft. then eight days. >> eight days. that's incredible. if -- although you were using three vehicles at the time. >> that's right. >> can you extrapolate to this,

if they are in the right area and have one vehicle that it shouldn't -- we're not looking at six weeks or six months. >> it could be to cover the whole area. remember, we are not just looking for an aircraft but debris field which could be hundreds of meters across and it could be just a plastic cup to tell them this is the right spot. it may go faster. >> do you think there's debris on the surface of the water but they can't find sglit i have to go back to the hms sydney that sank in world war ii. 600 people gone without a trace and thousand miles to the north, maybe more. >> mary, as an attorney for victims of transportation accident and their families. what an open-ended investigation mean for potential litigation? >> it means they would be litigating under the month montreal treaty. their litigation would be against the airline. the airline will be responsible for their passengers unless the

airline can prove it took all reasonable measures to prevent what happened. of course it is impossible show that because it could be mechanical, it could be a breach of security, it could be pilot action. so the airline will be responsible for its passengers. if and when they ever find anything else, usually what happens is they do a full and complete settlement or litigation. a few my opt out and say, no, we're going to wait and hold back on just potential finding something mechanical wrong, but the airline will be responsible. >> what does this do to the industry as a whole? does something like this have an impact? >> yes, it goes to the core. the iko, international organization, has already established and set up an extraordinary meeting to be held in -- next month in may in montreal where they will be looking at lessons to be learned. the airline forum will be discussing it at their general meeting in june. let nobody be in doubt, this is

going to change the way planes fly, the way data is handled and the way aircraft is tracked. >> just as really every crash, every horrific incident like this has had an impact on the industry. >> this will be much greater. >> really? >> yes. because quite often you change minor technicality, some procedure or crm management in the cockpit. this will go industry wiechld i will probably go across all forms of metal, the different types of aircraft and fundamental. the issue will be how long before the nations can agree on a course of action. iko is slow. it is tedious and can be bureaucratic. >> do you agree, mary, this will have this kind of historic impact? >> well, i think what's probably going to happen is nations will do it one by one. one of the biggest problems lths will be the united states because it is so very difficult to get the faa to act because

whenever they propose new regulations -- and they don't even need an act of congress. faa has the power to propose regulations like this. when they do it the lobbying effort is immense from transportation lobbyist to prevent expenditures of any kind. for example in the air traffic control system they have made simpb available $7 billion in loans to help get this done. and still they are complaining about expense. the faa needs to be the leader to get this done worldwide and they need a lot of pressure and congress cannot cave. if they cave it's all the over. >> pressure comes from passengers, as well, who are certainly more educated and more informed about what is going on in the aircraft and cockpit and mechanicals before because of this. i feel like i knew more than i ever knew before. coming up, what happens when and if the black boxes are found. we will show you the remotely operated vehicles that retrieve

wreckage from incredible depths. you see the mechanical claw. remarkable technology to show you. and another search going on an active search right now for hundreds of people missing after south korean ferry boat capsizes. imagine being on this ferry boat. authorities apparently told people to stay where they were. not go to the lifeboats them latest in a live update when we continue. and you get a delicious milo's kitchen chicken meatball. i wish you liked my cooking that much. milo's kitchen. made in the usa with chicken or beef as the number one ingredient. the best treats come from the kitchen. ♪ ...work with equity experts... who work with regional experts... that's when expertise happens. mfs. because there is no expertise without collaboration.

there are a lot of challenges as david gallo said it is unchartered territory at such depths. stephanie elam is on a vessel off the coast of california with more on how this works. take us through how does the sonar technology work? >> it's interesting it sounds simple when its explained to us. this senior hydroographer are used in the search for the missing plane. tell us how it works. >> there are a number of varieties of sonars. they come in different shapes and sizes.

this is multibeam. they are using side-scan sonar as the primary search mechanism. it will emit sound. as it bounces off of the sea floor, the sonar receives that sound and uses the reflection from the sea floor to build an image of what's on the sea floor is. >> is it easier to do deeper in or higher up. >> it comes out good when you are deep. you have a nice stable platform and the sonar imagery can be crisp. the challenge is getting that sdoe sonar down deep. that is difficult. you have to put it on a vehicle and it has other components and that's where the challenge is. >> let's look at what the data looks like when you get an image of this sound. that's pretty much what you are doing, right? >> right. we have been building a map over the course of the day here. you can see we have done this lawn mower pattern and going back and forth. here's where we are now and we will add to it as we go. in realtime we are able to see where we are, reconstruct the plan on the fly based on what we

see. in the indian ocean they are doing pre-planned missions because the vehicle doesn't come back for a long period of time. they have to use their best estimate to generate this. >> the side scan sonar looks weird. explain how this works. >> this is side scan sonar imamry. it travels through the water, hits the sea floor and continues on. that generates an image of what's on the sea floor. >> anderson, it's interesting because the closer they get the better the image but the higher up the more they can see what is beneath them. so it can be tedious to get a better idea of what is down there. >> are they getting realtime images or data -- i thought it was data they look at later. the fact there is silt down there could that make it harder to identify? >> well, the first one i think that is a james question. >> no, they are not getting realtime images.

we are able to do that here on the boat but they put that on the vehicle and the vehicle is down for a long time. they have to download the data which take thes a lot of time and go through it visually. that's a time-consuming process. the silt can impact the data. if something buries fully you will not see it on sonar at all. it is likely from the impact alone there will be a crater or some indication of something there. >> there could be some indication of manage happened there even with a few weeks that have gone by, anderson. >> fascinating stuff. if search teams find the black boxes or any wreckage from the plane at the bottom of the ocean the next thing is to bring it to the surface. they will use a remotely operated vehicle, a rov. there are two in a warehouse in maryland ready to go. the company that operates them has a contract with the u.s. navy and require them to be shipped out within four hours if they get a call they are needed.

we have more on the technology that can retrieve the objects from the depth we are talking about. take a look. >> reporter: this could be the key to solving the mystery of flight 370. it's a remotely operated vehicle or rov for short. once wreckage of flight 370 is identified, an rov like this one is likely the next crucial step in finding the plane's black box it is controlled from the surface using this joy stick. has lights to illuminate the stark black of the ocean deep. cameras transmitting back footage in realtime. >> tms. >> and high frequency sonar to combat the notoriously difficult visibility in the area of the indian ocean where the plane is believed to be. but most importantly, the rov has robotic arms called

manipulators. >> it has jaws, open and close the jaws. >> reporter: they are essentially mechanical hands able to retrieve objects from the ocean floor and deeper than any human could withstand. >> the retract. >> reporter: a second manipulator can be equipped with tools for cutting through metal such as on the fusage of a plane. >> look for a black box, not a problem at all for me to pick it up and put it in a basket and recover it back to the vessel. >> reporter: experts say top priority for investigators is to retrieve both the flight data recorder and the cockpit voice recorder. this rov called the try tan can go to depths of 10,000 feet. but the rov brought to the wreckage of flight 370 could withstand the pressure of 15,000 feet of water, under water pulses were detected at that

depth last week. and unlike the bluefin, searchers are currently using the rov is connected to the boat through a line called an umbilical and has a constant power source and is able to feedback information immediately. >> rov can stay submerged for days. >> reporter: and the hope is with these capabilities the rov will finally manage to bring some answers to the surface. >> amazing stuff. just ahead, breaking news in the race to find hundreds of missing ferry passengers in the frigid waters off of south korea. as the vessel was sinking they were told to stay in their seats instead of going to the lifeboats and where the search for steve faucet's plane went wrong. does it hold any lessons for the flight for search 370? i've always had to keep my eye on her... but i didn't always watch out for myself. with so much noise about health care, i tuned it all out.

vests taking cover, raising questions of how the crew handled the incident. >> don't move. if you move it is more dangerous. don't move. >> some passengers say they were given conflicting instructions over the p. a system. >> we were told toll stay where you are so we kept staying but later on the water level came up. so we were beside ourselves. kids were screaming out of terror. shouting for help. >> reporter: the ferry tilted to one side and sunk within two hours of the first distress call. investigators still don't know why it went down. >> people screamed in the ship, it tilted and stuff fell down. even people came sliding down. >> reporter: tonight parents are left gripping cell phones waiting for calls that may never come. officials are posting the names of passengers. when a name is circled, it means the person has been rescued. for those whose love ones have been found uncontrol canable emotion. for others, heart break.

>> so horrific for these families. are they all gathered, waiting in a central place for information? >> reporter: well, anderson, they are basically here. we have mothers and fathers who have spent all night here. they have been sitting by the side of the water looking out. it being pitch black throughout the night. they were still looking out on the horizon in hope of seeing something. that ship is more than 12 miles from where we are at this point. they have no chance of seeing anything but there's nowhere else to go. they want to find information. we have just been hearing one lady screaming and wailing, saying why did they announce they should not move from where they were? why did they not allow my minje, the name minje to get off the boat. the heart break is turning to desperation and anger as they discover there was these p.a announcements saying stay where

you are not jump off the boat. >> unbelievable people were told to stay where they are. any information that may have caused the ferry to sink? have investigators said? >> reporter: we are having nothing official at this point. all we are hearing is from eyewitnesses. one eyewitness said he felt a loud bump and the ship started to tilt and that's when think took the life jackets and started to jump in to the water. it does appear as though some eyewitnesss are talking about a point of impact and people falling over and becoming injured at that point of impact. we are hearing nothing officially at this point. the search and rescue operation is taking precedence. the investigation is going on behind the scenes. >> so horrific, nearly 300 people still missing. paula hancocks, appreciate it. students were texting loved ones as the ship was sinking. one teenager wrote to his mother, mom in case i don't get to say this, i love you. the mother didn't know the ship was in trouble and said why?

of course i love you too, my son. we have no way of knowing what happened to any of these students who actually texted. we want to bring a cargo ship captain and maritime safety consultant. what do you think could have caused this to happen? is human error the most likely explanation or is it too soon to tell? >> yeah, i believe it is human error listening to the reporters and what i have been reading today. it sounds initially the ferry left two hours later than usual, due to heavy fog. there's a possibility the captain may have been trying to make up time to stay on schedule and he may have taken a shorter route. again, getting off of his prescribed route. it sounds like he hit a submerged object which caused a gash in the hull which would allow a lot of water with. >> when you hear some passengers, or passengers were told toll stay where they were. to not get up or seek lifeboats, does that make sense to you?

>> no. that completely makes no sense to me. the first thing you want to do when you have a marine casualty is the preservation of life. that comes first. to evacuate those passengers, large amount of people on board, that's the predominant thing you want to document you want to get them out of the ship, out of the danger in to the open spaces so they can get to life rafts and get off the vessel. one of the things i noticed about the pictures i have been looking at, it doesn't look like one life raft was deployed. they are still in their cradles and nothing has been deployed which would go back to the training of the crew. how well was the crew trained? were they trained? and how often did they have training drills? we have to look at that to see what kind of training it is. >> this makes us think what would we do in this situation. what do you recommend, you are a passenger on a ship like this and obviously you get a life preserver, which i guess they were instructed to do. but then you go to open spaces? >> absolutely.

move to the open area where if the vessel capsizes quickly like this one seems to have done you can be evacuated off the vessel. staying down in the lower hulls of the ship when she is rolling over you should not be doing that. you need to get out. once the ship goes over on its side you have no lights and all the doors will be on the wrong side. with the buoyancy of a life jacket you are not going to be able to do it. we need to make sure everyone evacuates quickly as possible to where their station is, their life-saving station. >> if you jump in the water with, is it true you should get as far away from the ship as possible, that a ship sinking can suck people down who are in the water? >> well, it does occur. you want to get away from the vessel without a doubt. you want to get away as far as possible. with the cold water, you have to think twice of getting in to the

cold water. the thing to do is get to the life rafts. people could have gotten in to life rafts and plenty of small boats in the area that could have assisted with the evacuation of the passengers. so this gets back to the training and human error. we need to look at the decision making going on with the crew. >> captain, appreciate you being on. up next a standoff in eastern ukraine heat heats up. president obama weighing in. we will have the latest on that. ...work with equity experts... who work with regional experts... that's when expertise happens. mfs. because there is no expertise without collaboration. mfs. all stations come over to mithis is for real this time. step seven point two one two. verify and lock. command is locked. five seconds. three, two, one. standing by for capture.
