>> hello everyone, don lemon. it is fast becoming a day of flip-flops. we have been told that every passenger has been cleared but today in an interview with sky news, there was an explosive revelation. this is still a criminal investigation and everyone on board remains under suspicion. a complete turn around.

and then there was this. is. >> we have very much narrowed down the search area and we are very confident that the signals that we are detecting are from the black box. >> that is unwavering confidence despite the fact that the men heading u ining up the search te has been no major head way made in the search. it turns out it likely was not a ping at all.

interviewing people. some of these people include family members of crew on board the aircraft. but the whole notion that the 227 passengers who were cleared from the investigation by the police chief last week that should suddenly say that they are not clear. they said you're correct. all the passengers have been cleared. so what he is saying now has not

had an adequate explain nation yet. of why he is going against the police chief. not clear at all. >> not clear. if or when the black boxes are secured, who will recover the information from them? >> the police chief here said today malaysia will lead the investigation. that is an accepted fact under international treaty. they lack the experts to extract the information and they would have to appoint an expert to do that. he didn't say where that expert would come from, which country. we know that the families have been saying they want french experts to be involved because they know the french got the block boxes from the bottom of the ocean when their aircraft went down off the coast of

brazil. there's a lot of understanding on malaysia on the streets that the french are good at this sort of thing but we don't know which way malaysian officials will go. that's very much an open question. what is clear they will make the decision. they are not leaving it up to anyone else. they will pick who it will be. first, is it too early to rule anyone out? >> it's a bit sham bollic. and i specifically remember the inspector general of police saying that they have ruled out the passengers because he gave them the 227. and then we had to work out that meant the remaining number were members of the crew.

it's a bit late in the day for the left hand not to know what the right hand is up to. this far down the road they should be speaking. >> how do we know what to believe? and -- >> i think it is inevitable that there will be some discrepancies in fact. but something as fundamental as this, whether or not they have cleared everybody or not is a little bit basic and those sort of things we shouldn't be hearing about now. if one party is not sure you say i don't know. i don't know. >> let's talk about the data recorders when or if they are retrieved from the bottom of the ocean, is it feasible that the

malaysian government would say we want to analyze these? >> no. it's a technical issue. you can either do open heart surgery or you can't. where will the black boxes go? the uk, the united states, the ntsb, in france. my guess if i were a guessing man, i would say they will go to australia. enormously experienced. >> let's talk about the ping locator. so far, four pings. he is very confident they are coming from the black boxes. do you believe those comments

are well founded? >> yes. they are not in contradiction with each other. houston was talking about events that may have happened on friday. houston was specifically recording. nothing has happened. >> there is a slight nuance. houston said all along that he thinks its consistent with an emergency locator. >> we're very confident. >> we're very confident this is it. >> i think we have to allow the political speak. >> thank you richard. appreciate it. more coverage of the missing plane throughout this hour. next, four confirmed pings and the australian prime minister saying they are confident they know the position of the black box within kilometers. when are they sending subs in? and explaining what happens when a plane hits the ocean.

>> welcome back, everyone. i'm don lemon. there is yet another new search area. roughly twice the size of vermont. ocean search specialist mike williamson is here to talk about what lies beneath the ocean's is surface. how hard would it be to find a plane on the ocean floor? >> don, it's -- it really depends a little bit about the

seabed there. i don't think that's going to be the case if we can narrow down the geographic area certainly we have plenty of assets that can do a thorough search in this depth. >> what about the pressure on the ocean floor? >> the pressure is really not a factor as its about 10,000 psi or 8,000 psi. but it's ambient pressure. as long as the electronics are housed in pressure housing rated for that depth, it shouldn't be a problem. >> can a submarine with stand that depth? >> there are a few research submarines that can but generally speaking not submarine in the sense of the word that i think you meant. >> you were talking ability

submersibles, is that what you mean? >> there are manned submersible s remotely operated vehicles. the ship on the surface. >> but you can't really do that because that will produce sounds. they are trying to figure out for the black box sounds for the pingers, then you don't want any distraction from sound. >> we want to localize the search area to the highest degree possible. >> when and if they do find the

wreckage, how hard will it be? they will have to use cables. what's the system here? >> well, just last year expeditions brought up the f-1 rocket motors from apollo 11 and 12 from similar water depths, actually a little deeper. that was a successful operation. it's obviously something that can be done. >> all right. mike williamson. >> these are the trained specialists trained to knock everything out and listen for that ping. one set back. plus another big developing story we are following. >> get back. get back now! now! >> dramatic video of a very tense stand off in nevada.

members of a militia coming to the aid of a rancher. he says the u.s. government is unfairly targeting him and neither side is backing down as the stand off escalates. i don't want to think about the alternative. i don't even know how to answer that. i mean, no one knows how long their money is going to last. i try not to worry, but you worry. what happens when your paychecks stop? because everyone has retirement questions. ameriprise created the exclusive confident retirement approach. to get the real answers you need. start building your confident retirement today. i don't know. how did you get here? [ speaking in russian ] look, look, look... you probably want to get away as much as we do. with priceline express deals, you can get a fabulous hotel without bidding. think of the rubles you'll save. with one touch, fun in the sun.

i like fun. well, that went exactly i as planned.. really?

>> sit a it is a western show down 20 years in the making. and it has gotten louder and more intense. you will soon see how the confrontation is over one rancher who has refused to pay grazing fees.

the u.s. government is seizing his cattle. we are loud outside of bunkerville, nevada where demonstrators have been gathering. why won't he pay the fees? >> it's because he says the federal government doesn't own the land, he does. it has been in his family for multiple generations. they don't like what has happened to this rancher, the people that you see behind me. at one point, don, things got hostile. >> get back now. >> this dramatic video wednesday showed the rising tension over surprise desert in nevada about an hour and a half outside of las vegas. with dogs and tasers, these federal officers were trying to clear a road way blocked by protesters. >> this is america and they are the aggressors. we're not. >> it all began when the usblm

began seizing hundreds of cattle owned bay local rancher, a well liked figure in this rural community. >> bundy and his son claim it's an illegal action because the cattle and lands belong to them. >> i crew up on this land and all the rest of you, most of you did. and never once have we ever been kept away from going up on this land. >> but the blm and the national park service says the bundys don't own it the government does and therefore they need to pay grazing fees for the livestock. uncle sam says the owner owes more than a million dollars in unpaid debts spanning two decades. this week the blm said enough is enough. they had this run in with supporters. federal authorities say a police

dog was kicked and officers protecting a civilian driver were threatened and assaulted and as for the seizing, they have tried. this is an option of last resort. the dispute has brought self-proclaimed members from across the country to fight what they say is u.s. tirny. >> there is no answer as to how long this stand off will last. >> and the story gets more interesting because nevada's republican governor is actually backing mr. bundy. the cattle round up continues. mr. bundy says he will do whatever it takes to protect his property. now that you have militia men apparently added to the mix, many of whom are armed, there is

a concern that things could get uglier. >> absolutely. dan simon will be standing by with that story. >> some teenagers trying to figure out what to do with their lives will never get the chance to do it after an explosion on the highway. the highway patrol says both drivers, five students and three chaperons were killed. many others, mostly students survived including gutierrez who was tweeting before and after. can't believe this just happened. i was asleep and next thing i know i was jumping out for my life. >> i went outside and everything was in flames already.

there was a couple of explosions after that and a lot of people screaming and begging for help. >> there was no way you could get near it. >> all of the sudden i heard a sonic boom and i -- the house shook. when i got there everything was engulfed and it was still spewing black smoke. i just started praying like crazy. >> the bus was one of three carrying low income and first generation students to see a local university. a statement, all of us are deeply saddened. we are cooperating fully with the officials investigating this accident. more coverage of missing flight 370 next. one senator wants all commercial pilots to be armed. will that help make flights safer or make it more dangerous for passengers? we will debate that. plus analyzing a debris field can reveal a lot about what

happened right before a plane crashed so what does it mean when there is no debris field? that's next.

>> we are nearing the bottom of the hour. i'm don lemon and we have now learned that the fifth ping turns out it was not a ping at all. but as for the four previous signals picked up by the u.s. navy towed pinger locator, the

prime minister is confident they are from flight 370. >> we are confident that we know the position of the black box flight recorder. by confidence in the position of the black box is not the same as recovering wreckage from almost four and a half kilometers beneath the sea. >> the search area, smaller today. a total of just 18,000 square miles -- just? that's still a lot. that's barely a fifth of the size of a week ago. the listening area, smaller still. and malaysia's defense minister tells us that the cia and british intelligence are all part of the team to explain the disappearance. he says everyone on the flight remains understood suspicion.

that is quite a bit to chew on. also your book is called extreme fear, the science of your mind in danger. >> i just wanted to make sure. is this a crime or an accident because they are not ruling anyone out? >> they're not going to rule out there is a crime or an accident until they get the wreckage. >> but they said what? april 1 they came out and said everybody on board, at least the passengers were ruled out, but the crew they weren't so sure and now they are saying no one is ruled out. >> it sounds like a flip-flop but it may be them saying we have looked at them, we didn't find anything and we're not ruling it out. i think it's appropriate not to rule anything out. >> i have not been with you, but we have been covering this day after day after day and we have seen a lot of contradictions and

this appears to be one. >> right. i mean, especially when things come from unnamed sources. there has been all kinds of things so it is really hard to make sense of what to really believe. >> is it fair to consider this a botched investigation? >> it's botched messaging. that's as far as i could go. a huge task to find i don't really fault them for that, but what they have come out with and had to pull back is the first time i have ever seen it. >> and it's so important. because in the absence of physical wreckage, these statements are all we have to hang our hats on. >> we have heard reports that they scrambled jets but they did

it too late. actually telling people about a missing plane. had they had their ducks in a row, don't you think it might have been a different investigation at this point? >> they may be a week ahead of where they are right now, which with the batteries dying on the locators would have maybe made a big difference. >> every minute makes a big difference. >> yeah. especially, don, i think you're right. to make statements that then you have to retract or walk back from, it's happening far too many times. australians have also had to walk back. >> i want you guys to respond back. here in this country we have rand paul. he is saying let's arm every single pilot, every one. that's the most cost effective way of preventing another 911. i thought we had the full screen. is that a good idea? >> it wouldn't have helped in this case because the leading

suspect is the pilot so he's already according to them, the cause of all the mayhem in the first place. give him a gun on top of everything else, i don't think it will do any good? >> the armored cockpit doors have prevented another 911 so you already have that in place. now there are pilots and i have spoken to a lot of them who want the protection of a gun and then you are introducing a weapon and as jeff just said, sometimes maybe the pilot. >> aren't the air marshalls armed? >> yes and they are on the airplane and that does respond to some of what senator paul is talking about. >> if the air marshall is armed and the pilot is armed, the pilot doesn't usually know who the air marshall is. >> they will check in sometimes with the flight attendants and the pilots might know through them. >> but it's kind of easy to figure out. usually if i am sitting next to an air marshall i say you're an

air marshall and they say how do you know? the haircut, the shirt. not that i want to give anything away. at least it would counter balance, however many and you have a pilot that's on you don't think that would help? >> maybe what you need to do is go the opposite of what rand paul is talking about. if you start becoming worried about the pilot, the current situation is there is a key pad to get into the cockpit but there is also a dead bolt. the pilot could flip that piece of metal. if you start to doubt the pilot and maybe the people in the back should be able to take over. it could be something as innocent as a pilot having a heart attack after having locked himself in. >> maybe you take away the dead bolt. >> so many things that could come into play. i find it interesting that the flight attendant stands with the

cart. what good will that cart do but maybe a few seconds. we appreciate it. finding wreckage from flight 377 depends not only on where it crashed but also how it hit the water. gary tuckman explains. >> not a speck of wreckage has been found from malaysian airlines flight 370. is it possible that all the wreckage sank? >> the chances of no debris? very, very remote. >> the amount of debris on top of the water would vary based on the scenario of how it when down. for example, if it went down in a steep dive at high seas. >> the wings were dorn off. large parts were torn apart.

the debris field was fairly scattered and weeks later, parts and pieces and personal effects were still being combed from the ocean including by fisherman. >> what if there was a ka fast fee where it exploded in the air before crashing. that's what happened with twa flight 900 in 1996 and another in 1988. >> in the case of an explosion in the air, the debris field is not scattered in terms of feet and hundreds of feet, it's miles. in scotland it was scattered over miles. some pieces found as far away as ten or so miles at least. >> then there is this scenario. a hijacking of an either yoebian. in that case the pilots ran out of gas and were forced to make an intentional landing in the

indian ocean. that would result in significant debris. >> remember, water is like concrete. you hit it hard enough and it destroys the airplane's integrity and you will have pieces that will be there and it will open up things like compartments and sections like the airplane. >> indeed that sentiment is widely agreed upon by experts. here at the accident lab, the director says crashes on the water will almost certainly leave floating debris. the lingering question? how far away will it float? the best case scenario will be the type of landing made by captain sully sullenburger. >> sully did an incredible job of flying but he landed on a river and the river is pretty relaxed, let's say, by comparison with an ocean where

you have got swells of 10, 12, 16 feet. it's pretty difficult to make that kind of landing on water. >> the search, of course, continues for the wreckage. the landing scenarios just mentioned all part of the investigation. gary tuckman, cnn los angeles. >> crews are searching thousands of square miles. we are taking a closer look at these pinger dethe teection tea. we are answering your viewer questions. if pilots are both suddenly incapacitated, can other crews still get into the cockpit? we were just talking about that. you're watching cnn's special coverage. good gummies. they're delicious, and a good source of fiber to help support regularity. wife: mmmm husband: these are good! marge: the tasty side of fiber.

>> welcome back to our special coverage. searchers are race to find more clues this hour to find the missing airliner. 30 crew members are aboard the ocean shield right now. it is towing a pinger locator that has already found four pings. time is running out to get as much information as searchers can before the pings stop all together. i want to bring in brian todd in washington and his unique work. >> the pinger locator. on board the ocean shield from phoenix international. control rooms on board the ocean shield, their job is to do nothing but listen for those sounds and watch these monitors.

they are doing it for hours on end and right now we are just waiting for any word of any other sounds. i spoke with paul nelson. he's a project manager. i asked him about the process and hours that these guys pull on board. >> what are the ups and downs they are going through? >> there's two shifts. they work 12 hour shifts. so the first crew will work from midnight to noon and the next team will work noon to midnight. you're monitoring the weather. you're watching what's coming as far as weather. monitoring the seas and you're sitting in front of this screen hoping and praying that you're going to hear something. it's very tedious. this whole operation is very tedious. >> so if you can just imagine what it's like sitting in the control rooms for all of those hours listening and often hearing absolutely nothing and

>> every day new questions are pouring in from our viewers and we're getting experts to answer them for you. tweet your questions to @don lemon. back with me now is jeff wiess.

>> got it. >> i'm going to throw the first question to you from sarah. sarah says this is for you. >> it could take hours or days, but most agree that it would be difficult to land a plane like that in the ocean, in which case you are more likely to see a more catastrophic break up. it's going to go down pretty fast. it's going go pretty much straight down. you had a pretty tight little pattern. >> justin, this one is from

cody. if pilots are both suddenly incapacitated, can other crew get into the cockpit? >> yes, with a key pad. the pilots have a last minute bolt that they can latch. the flight crew will have the combination. >> and your related question is what options would the malaysian search planes have if they found mh 370 and pilots were unconscious. >> i don't understand the question. >> what options would the search planes have had if they found mh 370 and the pilots were unconscious? >> like a zombie? >> honestly, there is something that may come out in the future is the airplane could be remotely flown. no current airliner can be

remotely flown. >> i have this one. someone just sent this. jim says, we discussed this a little bit. a plane running out of fuel falls backwards tail first. when it hits tail first, what is the outcome? >> i think there is a lot of issues in that question. if an airplane is on auto pilot and it runs out of gas, the engines will stop powering the aircraft, it will slow and the auto pilot will try to maintain the altitude and then the airplane is going to come close to a stall and the auto pilot would be kicked off. if it lands tail first there may be a break up and maybe a potentially violent break up.

but again, we don't know what happened. >> okay. jeff. jay asks would the plane have had enough fuel to make the drop, climb, and still have enough fuel to reach the pinger location? >> to go down low, this is the idea that over the peninsula it went down to 4,000 or 5,000 feet. that would be a very fuel intensive maneuver. maybe it wouldn't have had enough. >> nicholas says the 777 is designed to glide when it runs out of fuel. i don't know what that means. >> after it runs out of fuel it will try to maintain the altitude. he is saying it will glide like a glider. >> but the ocean is so turbulent it's not going to land like on

>> this is top of the hour in for brook today. >> used the words very confident. >> we have very much narrowed down the search area and we are very confident that the signals we are detecting are from the black box on mh370. >> it has now been five weeks since the plane vanished. 227 of the people on board were passengers. last week the inspector general

made the announcement that all had been cleared of any suspicious role. a complete turn around with no real explanation why we were ever told otherwise. what else did we learn from the man who has been the face of malaysia's investigation? >> he has been the face of it. he has been the man to lead the majority. he admits authorities have made mistakes. we know that we're talking about the country's transport minister. he says handling the event is, in a word, complicated. listen to him here he is. >> there are cultural differences. there are times when we are lost

in translation. we are learning through this process. i'm not saying we must handle it perfectly. >> as you mentioned, mixed messages are coming from malaysia. in the beginning of april, the malaysian police chief said this about the investigation and who they were specifically focusing on and who they were not. take a listen. >> only the passengers have been cleared. the rest? no. >> we do know of that man there, the police chief there in malaysia they said they were still looking at the flight crew, the ground crew and the people who prepared the on board meals. but you heard right there the passengers were clear. but the transport minister contradicts that saying, quote, everyone on board remains under

suspicion as it stands. he made a similar comment a few days after the police chief made that comment. the transport minister is suggesting there may be more details we don't know about. he said the whole passenger manifest, the fbi looked at the simulator. that will all come out later. i find it difficult to say more without jeopardizing the investigation. he goes on to say the truth will preva prevail. we haven't heard any word of any red flags being raise d. >> and as for the search, we heard australia's prime minister say he is confident. there was a set back with those pings. right? what happened? >> we got so excited yesterday about the the possible fifth ping but turns out now that was not related to the black boxes belonging to flight 370. over the past week, four pings have been detected.

that fifth one was not from the black boxes. very confident saying that the four pings that they did detect believe they are from the black boxes. giving a lot of confidence as we move forward. >> thank you very much. i want to bring in our experts to weigh in here. with me now is richard quest. michael, to you, the government is saying everyone is a suspect. what do you make of the suspect happening ten days after the country's top police official said otherwise. >> there are so many facets to this investigation that i think we are suffering from an overlap of perceptions. they declared an independent

investigation in charge. under them, the u.s., the uk, france australia and china. >> this is -- these are both coming from malaysians. both are coming from malaysians. contradictory. >> they are but we must accept. >> that's a search. >> and from the malaysian police, it has nothing to do with the search. they are saying in the investigation, all passengers are ruled out and they are saying, okay, everybody is ruled in. one has nothing to do with the search. >> there are contradictions going on. but let's go back to the conversation. it all melds into one.

what malaysia is doing shouldn't be super imposed on the search area that is going on down south. we shouldn't be painting the entire process with kriks. >> i'm trying to separate the search from the investigation here. i'm strictly talking about the investigation. if i misworded my question, i'm talking about the investigation and what the malaysian officials are saying. do you understand what i'm saying? >> i do and as renae has pointed out, one person said one thing and another person said another ten days later. if that was the first time i had seen anything happen, it happens every time. it shouldn't. it's clumsy. you are left wondering rightly, your left wondering are the

passengers under investigation or not? he actually said only the passengers have been cleared. he didn't say i can balance this on the head of the pin. he didn't say all passengers had been cleared. it's irrelevant. it's parsing words. they both said different things but here's the difference. >> we're going back to the why bit. let's get ahold of the black boxes and understand what happened to the airplane and all of this information will hopefully fall into place. >> michael, here is what routers is reporting. what may have been done trying to identify the track, the flight, right after it went

missing. can we believe what the government is saying when there have been so many contradictions? >> i think, you know, it's building up confidence it's like crying wolf now. we should be very cautious about what the malaysians are saying and using all the other evidence. what we mean is what the search area is. let's look at the distance to the south china sea. >> you ear not saying it is where it you say it is? >> this particular investigation is a more serious one. it wouldn't have made any difference but this goes to the

heart after 2:00 in the morning when the plane went missing and what information was known at that time and who was following the plane in realtime. it wouldn't have made a difference to the results, you're with me on this? >> it certainly would have made a difference in the searching and looking. >> not necessarily. we knew about the western part of the search pretty much the next day. the question is -- the fundamental question varies. when did the malaysian military know, have reason to believe and then report that the plane had gone dpsh. >> you don't think it would have given a better location and a better confirmation as to what happened to the plane? >> if they had put up a dispatched jets oor cramabled if

they had put them up to see what was happening. the orthodox thing to have done would have been to send up some sort of aircraft to investigate line of sight we don't know that. >> i could keep talking about this forever. just ahead, are we getting closer to the point where crews will give up hope on more pings? an ocean expert gives her opinion coming up. plus how did the woman who threw a shoe at hillary clinton get past security? this may have been a major security breach. stay right here.

>> welcome back, everyone. the prime minister says crews are within some kilometers of perhaps finding the black boxes for flight 370 but officials warn there is still a long way to go in the search. expedition logistic specialist is here to talk about the difficult search underwater. we know it is very difficult. the thing is even if they know approximately pretty close to where things are, it could still take them quite some time to find it. >> it is and technology that we're working with here is good but it's not that good. it's not fail proof. we're still in a position where we're trying to deploy this auv, which is the next stage. this will still mean a much smaller search. >> smaller than the area you have now?

>> that's the next phase only after the pinger battery runs down. they need to find the voice recorders. >> they are going let some time pass unle the they know two or three days. >> you're talking about what you you call them? auvs? they go back and forth, correct? before get here you said it's got to be a lot narrower. >> to have even ten miles by ten miles. you would like something smaller so crow can put an auv down and get the data. it will take about 90 minutes for it to cover about 15,000 feet.

so it will take some time. and then they will have to bring the auv back up, collect the data, take it back down. this could go on for days. it's weather dependent. ideally the conditions will be in favor for them and they might still be narrowing down the search pattern at that point. >> many people might wonder why don't you use every resource available but they would be working against themselves because they're trying to listen for the ping and the auvs. >> we're really not there yet. >> it's hard to predict just how long before we are there. >> i think lit it will be the n few days where we have a smaller

search area. >> why do you think the australian prime minister is so confidence? i had someone who helped with the titanic, and he was floored and said i don't know how he can say that statement? >> he is, i think, being a little bold on that but i think he has more information than we do. >> thank you. always a pleasure. we're focusing on the pa lazian government governments conflicting information to mistakes. what they got right and wrong. and next, did you see this? a former secretary of state dodges a shoe. she brushed it off with a joke but this could point to some very serious security issues. ameriprise asked people a simple question: can you keep your lifestyle in retirement? i don't want to think about the alternative. i don't even know how to answer that. i mean, no one knows how long their money is going to last.

i try not to worry, but you worry. what happens when your paychecks stop? because everyone has retirement questions. ameriprise created the exclusive confident retirement approach. to get the real answers you need. start building your confident retirement today. gunderman group is growing. getting in a groove. growth is gratifying. goal is to grow. gotta get greater growth. growth? growth. i just talked to ups. they've got a lot of great ideas. like smart pick ups. they'll only show up when you print a label and it's automatic. we save time and money. time? money? time and money. awesome. awesome! awesome! awesome! awesome! awesome! awesome! awesome!

>> kathleen -- if confirmed by the senate, he will take over as an agency that has taken heavy flack. >> who can forget the glitches that kept people from signing up up for health care. she encountered an error. . >> finally feel iing -- unfortunately, a page is missing. so i have just -- i am just grateful for having had this wonderful opportunity. >> i have been there when there

is no tele prompter. >> there are serious concerns and questions about how a protester got into a private event in las vegas to throw a shoe. i'm going talk to a former secret service agent about that but first here is the shoe toss. here is mrs. clinton's reaction. >> what was that? a bat? was that a bat? is this part of cique de soliel? [ applause ] my goodness, i didn't know solid waste management was so controversial.

[ applause ] thank goodness she didn't play softball like i did. >> so that's probably why her reaction came so slowly. she says what was that? if you have been there you understand that. so we don't know who this. we are to answer some questions. how could someone get past security. >> we need to assess what past security means. there are two security check points. the first being where's your ticket? is your name on the list? are you allowed to come in? that is event coordinator.

once they say okay this person is invited you go through the check points and you are brought in. it's very likely she did go through the second layer but the first layer is the one that failed where the host committee assesses who is invited. >> it's a lot of compromise and working together. >> you think a lack of security. okay. fine, someone probably should have seen her. what are you going to do? take everyone's shoes? >> are you going have everyone's shoes? the other thing, keep in mind, often a lot of people do get up

and take a photo. that is permitted in certain situations. they always keep a buffer. there is usually seven to ten feet this is her motorcade during a visit to egypt back in 2012. >> some say yes, i will ace light myself. i kept myself in this bubble to keep myself safe. usually they don't want that. to be out there. to be close to the public, to shake hands. and here in comes the conflict.

you shouldn'tn't be driving for something like that. make sure we're not going. sometimes they are published or leaked. he did what hillary clinton did. he laughed it off. >> that was in baghdad. >> embarrassing moments. >> beneath of them got hit. >> up next, malaysia now investigating its own response in the disappearance of flight 370. admitting they botched it.

(mom) when our little girl was born,

we got a subaru. it's where she said her first word. (little girl) no! saw her first day of school. (little girl) bye bye! made a best friend forever. the back seat of my subaru

is where she grew up. what? (announcer) the 2015 subaru forester (girl) what? (announcer) built to be there for your family. love. it's what makes a subaru, a subaru. >> losing your home in a fire can be devastating. when firefighter jim leary didn't have a way to care for animals. >> once the fire is out.

i would see people be forced out of their homes and would hate to see them be forced to lose their pets as well. >> i am headed to the scene now. we respond 24/7. >> we do for pets what the rod cross does for people. >> hi, baep. come here. >> she has been at my house and the owner said she was pregnant.

free for them. >> my hope is that it's a fresh start that we can move forward together. >> if you know someone who deserves recognition, tell us about them on cnn.com/heroes. >> families have just learned as far as malaysia is concerned, the 227 passengers are still suspects in this disappearance.

just days after these passengers were said to be cleared in this criminal investigation. >> as we have said earlier, only the passengers has been cleared. the rest? no. >> let's go now to perth australia. do we know why malaysia's top brass can't get their stories straight? >> yes, one of the problems that happened from the start, of course, is they don't talk to each other at certain levels as well. we saw that with the malaysian military slow to report what they had seen on their radar in terms of the aircraft taking that turn back across its territory. they didn't tell authorities for some time. it's kind of that silo situation. the military doesn't talk to civilians all that much. that's going to change. they're going to already have an investigation underway that lack of communication so i suppose

that is another indication to make those families happy at all. they have not been happy with the way the malaysians handled it from the start. >> angus houston said there is no major breakthrough. >> yeah, well, keep that in contest. she was confident that the four pings we do know about. a fifth ping discounted in the last day or so. the head of the search operation retired vice amarshall angus houston said he is confident -- optimistic that they would find

the wreckage. here is part of what you like to say. >> we have very much narrowed down the search area and we are very confident that the sillals are from the black box on mh-370. >> he said that they have narrowed the search did you -- that tighter area. it's something like the size of a state of the month. so it's still a bij area that they are searching. and the pings are being the cell towers. the more they get the more you

can narrow it down. they really do have to narrow it down as far as possible before they put the submersible down because that thing goes at walking pace. they have tried to narrow that down further. still a long way to go. >> michael holmes, thank you. coming up, if the plane did crash into the indian ocean, what would that look like after more than a month under the sea and how would that affect what investigators are looking for and where? plus a mystery on the board of alabama. two navy seals found dead with large amounts of heroin found near their bodies but the family says it doesn't add up. see what he found, next. how much money do you think you'll need when you retire? then we gave each person a ribbon to show how many years that amount might last. i was trying to, like, pull it a little further.

[ woman ] got me to 70 years old. i'm going to have to rethink this thing. it's hard to imagine how much we'll need for a retirement that could last 30 years or more. so maybe we need to approach things differently, if we want to be ready for a longer retirement. ♪ if we want to be ready for a longer retirement. 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. it's been that way since the day you met. but your erectile dysfunction - it could be a question of blood flow. cialis tadalafil for daily use helps you be ready anytime the moment's right.

>> in the coming days we could solve a mystery on a ship that you have seen in the movies. the story became a movie last year and now the same ship is a backdrop to a case of entry. when he stopped, police found two former navy seals dead and drugs on the scene. but an overdose? there are doubts. here is cnn's investigation correspondent, drew griffin. >> it was late afternoon and the two former u.s. navy seals

hadn't been seen all day. on board the alabama, mark kennedy's cabin door was marked and inside no one was responding. crew members decided something was wrong and called police. >> what police discovered in the caribbean was that one of the security officers and the other one was the head was leaned against the wall. >> two days after docking in this tropical resort. two private security guards were dead. the autopsy showed both died coupled with suspected heart attacks. there were traces of heroin in the room and a needle but the investigation has found no

history of drug use by either man. sit a mystery that spans thousands of miles back to the homes of the two former seals in the united states. jeffrey reynolds was playing basketball with his son outside of their home. clean cut. he was a man who didn't even drink alcohol. >> jeff was just a friendly good looking young man that seemed to love life. he liked his job very much. looked forward to doing his work and he looked forward to spending time with his family. >> i just didn't believe it. >> in baton rouge, louisiana, mark kennedy was so dedicated to physical fitness, friends

nicknamed him captain america. he was a decorated war veteran. >> he didn't look like a guy on drugs. he was always running around the block. him and his wife were both real active. >> family has told the local newspaper that he has no desire to talk to anyone. >> i have not see him since he been gone. it's been a hard loss for the neighbor. >> this is why police are trying to retrace the men's steps on shore. >> eyewitnesss. and to prostitutes is painting a different picture than the clean cut former navy seals friends describe back in the united states. police say their investigation so far has found reynolds and kennedy were enjoying a night out on the town, eating in a

restaurant together, hitting a casino and at 3:00 a.m. being asked to leave a bar at closing time. a laumpt source confirms video images from outside show the men meeting two women disappearing down a dark corridor. that same source described the women as prostitutes and said they took the two private security guards to a place where the men could buy heroin. police are now reviewing toxicology reports that were just finished this week. if those reports determine either the heroin or something in that heroin caused the deaths of these two former navy seals, there could be criminal prosecutions. police say that decision most likely will be made in the coming week. >> are they considering possible criminal charge, is there a consideration that the two men were murdered? >> there is no indication that anybody forced the drugs upon the two men. if they can determine that the

drugs or more importantly, they are leaning towards something in those drugs was involved in the actual deaths, it could lead to charges associated with not only delivering the drugs but potentially charges related to the murders -- the deaths of these two men. we will just have to see how they play it out and what the reports say. >> thank you very much. we appreciate that. next on our special coverage we will talk about the four different ways a plane can crash and what that says about a lack of debris. plus once crews start looking for wreckage, what would it look like after being underwater for a month? stay right here. if you wear a denture, touch it with your tongue.

if your denture moves,

it can irritate your gums. try fixodent plus gum care. it helps stop denture movement and prevents gum irritation. fixodent. and forget it. . there are many ways a plane can land on water. in a crash situation, the type of landing can determine how much debris is left and where to find it. here to give us a closer look at what that means for flight 370, ocean explorer and specialist christine dc christine dennison and michael kaye. for example, a nosedive. let's start with the nose-dive. >> don, i'm going to come back to you on this. >> no, no, no. >> it's too simplistic. look, we spoke the other day -- >> that's why we are here. with all due respect, that's why we are here.

to breakdown the crash scenarios. many people are wondering if the plane landed on the water, what happens with a nose-dive? >> power on or power off. that's the reality. >> the pilots would not let a scenario occur where it was going to run out of fuel and make an uncontrolled approach. >> okay. >> so the reality is that if they are in this part of the world that didn't have a diverse, they couldn't make land, they were going to make an approach with power on. and i think that's important because with power on you can drop the flaps, the gear, and slow the plane down. >> so if the pilots of not in control, if they are incapacitated, could it be a nose-dive landing? >> it could be. >> what happens with a nose-dive landing? >> well, it's going to be a hard impact. as we've already heard, when we spoke yesterday to the chap who did the titanic, it's like cement. the water is like cement.

we must get away from this notion that landing on water is going to be softer. it's not. a nose-dive is just like going into the -- >> so it's going to cause debris to scatter everyone. >> extreme fragmentation. >> so if it breaks apart midair, that's going to give you the widest debris? >> yes. depending on the speed, the altitude, the higher the aircraft is, the faster the aircraft is, if it's going to start fragmenting, you're going to get a greater spread area over the ocean. >> so landing on top of the water, we were talking about the sully sullenberger type of landing, chances are, any ocean is so volatile, we're not going to have this kind of landing. >> no. the miracle on the hudson, it's completely in tact and when it sinks, it's going to be in tact. >> so what is it bound to look

like on the bottom of the ocean, this debris? >> well, i think i'm going to have to agree with you on this. >> no, let him finish but i wanted to go through the scenarios and then what you're saying. but what would the debris look like after this -- after a couple of weeks down there? >> it could be a large debris field depending on how this plane came down. either way, you're going to have -- you may have a fairly large section that fuselage that is in tact lying at 15,000 feet. you could also have very scattered debris field, depending on impact, if it broke apart. there are parts that -- we don't have a debris field topside, which everyone is wondering about. >> but how long does it take before the silt covers it and -- >> at this point it wouldn't happen in a month. you don't have any currents down there. anything that has fallen is going to be pretty much where it lays. >> here you go, mike kaye. i'm doing that because we're answering viewers' questions.

but you're saying that we have to listen to what the investigators are saying. >> we've been doing so much analysis on this and we go back to where the transponder is and we have a look at the nature of the route but if there's going to be an explosion that would suggest a terrorist bomb or something like that, it's not going to happen at the physical outer limits of the endurance of the plane. at the moment the evidence suggests that the pings and all of the other analysis, the aircraft continued to the point where, most likely, it ran out of fuel or it was at the limits of its endurance. that's why we're in that search area. what i want to do is talk about the possibilities of that scenario rather than covering a million different scenarios when we know we can zone in on something. >> we're talking about have you we ares' questions. >> i agree. >> anything else? >> no. the most likely scenario would be -- and i thought this was a brilliant point brought out by

mart t marty, a powered on approach. >> thank you, sir. coming up, he's a man who brought you the mega film blockbuster "the titanic." james cameron is going to give us his take. stay with us.

because i live in new york. it's a big day for bubba. >> reporter: hey, it certainly is a big day for bubba. you say that he's going notice. i say that this guy is simply on fire and i mean that. he had five straight birdies from 12 through 16 which is absolutely impressive. that means corners 11, 12, and 13 and those are the holes that in the first round and today in the second round has caused quite a few number of problems. when we talk to bubba watson, it's this kind of play that we expect from him. he's the best in the world and he's a true bomber. easy electrifying to watch with that unorthodox style of swing. he's excellent on the greens and this is a guy that obviously he's won the masters before. he was the 2012 champion. certainly he knows how to win the masters.
