multiple ships and boats and coast guard, they need to be listening for the pingers, the underwater pingers from the flight data recorder, hoping they can find the black boxes. >> i want to go back to the air france flight 447 when it crashed over the atlantic en route to paris. it happened on june 1, 2009. that was a cataclysmic crash, no one recovered from that but it took two years for the black boxes to be recovered. how long first of all, tom, do pings operate in water? how long will that battery keep it going and with the depths of the mediterranean, they don't parallel those of the atlantic, don't they? not that far off the coast line of egypt. >> boy, i'm no oceanographer, i would have to hit the google on that, but i can tell you that 22,000 feet is the depth at which the pingers operate. they operate at 30 days -- that's the hope, 30 days. there was an initial report from the egyptians and then confusing information from the egyptians as to whether the military did or did not pick up a sick natural. it could have been an elt -- an e emergency locater transmit when the plane hits s

we don't normally characterize a pinger as a distress signal. you could characterize the elt because it's for the purpose of locating a airplane. so it will be interesting to see if that is pinpointed, whether it was on the water or some land mass some where two hours after it supposed event. >> greg, this is more than just semimantices. and the officials are reporting there was a distress signal that was determined. greg, semantics is important. this is two hours after it first disappeared from communications, that it doesn't necessarily have to imply there was a human aspect to it, there was no actual signal, the pilot or the co-pilot was able to call in. it could be upon worst-case scenario, if there was impact on water, it could trigger the impact that could trigger a distress signal. >> it could be, yeah. if they are combing the area, to hear the pingers, those are acoustic signals. so you have to have listening devices in the water, in the area, to hear one of both of the pingers, the elt of course is not submersible. it will fire and prov

i want to tell you about the pinger.talk about it often but it's attached to the flight data recorder. it's this underwater beacon that's mountod a bracket, boltod t bolted to the front. and it's operates while immersed in water. 30 days of battery life, 20,000 feet. you heard bill say we're talking about 4,000 to 5,000 feet of water depth there but we've seen in the past problems with -- there are layers if you will, temperature layers in the ocean or in the sea in this case. and those layers can make it difficult to hear a ping. if a pinger is going off on the bottom of the sea it can kind of bounce around, echo around. so you might hear it on a microphone that picks it up quite a distance away because it's echoing and bouncing off almost a wall. it's going to be listening for the pinger and hopefully finding it n triangulating it and figuring out where it is. that's not always easy because of the various temperature layers in the water. but they are in a lot better shape here in the mediterranean searching for that pi

the pingers are almost certainly working and you'll hear those soon.nd the recorder and then the real question is how easy will they be to recover. good to see you, thank you so much. >> we'll be right back. ♪jake reese, "day to feel alive"♪ ♪jake reese, "day to feel alive"♪ ♪jake reese, "day to feel alive"♪ man, it's like pure power at your finger tips. like the power to earn allstate reward points, every time i drive. ...want my number? and cash back for driving safe. and the power to automatically find your car... i see you car! and i got the power to know who's coming and when if i break down. ...you must be gerry. hey... in means getting more from your car insurance with the all-powerful drivewise app. it's good to be in, good hands. ♪ no, you're not ♪ yogonna watch it! ♪tch it! ♪ ♪ we can't let you download on the goooooo! ♪ ♪ you'll just have to miss it! ♪ yeah, you'll just have to miss it! ♪ ♪ we can't let you download... uh, no thanks. i have x1 from xfinity so... don't fall for directv. xfinity lets you download your shows from anywhere. i us

second day. >> i was just going to ask you that, we all became very familiar with the pinger in the wake of that malaysia air flight. john, thank you so much, i appreciate you. >> we'll take a quick break here, when we come back here live from france, we'll take a look at what happened today, what it means for politics, what it means for national security implications, we'll take a look at that plus more reaction from here in paris right after this. fact. there's an advil specially made for fast relief that goes to work in minutes. the only advil with a rapid release formula for rapid relief of tough pain. look for advil film-coated in the white box! relief doesn't get any faster than this. >> i want to express my condolences to egypt and to all the countries impacted this morning by the egyptair flight over the mediterranean. >> secretary of state john kerry offering the condolences of the united states of america, when we come back, were they expecting something like this in france? we'll dig into that and what donald trump and hillary clinton said about today's plane crash, we'll

so we should make clear that we don't have pingers at this point. in terms of official information, let's all stand by as i go to london where nbc's kelly cobiella is standing by. kelly has heard from the french aviation minister. kelly, what have they told families and loved ones of those 15 that were onboard this flight? >> reporter: well, they're sending their condolences obviously alex ate this point. we don't know what happened at this point, but the assumption is it didn't end well. so they're sending their condolences and support to the families. 15 french nationals on that plane. and also sending their support to egyptian officials, offering any sort of search and rescue help that they might need from the french. they also mentioned the transport minister said that about those three security officials onboard, remember we were told there were 10 crew members onboard, three of them security officials. transport minister saying this is normal operating practice. probably something that the french don't like to talk about openly, obviously matt

one purpose of that is the pinger can work up to death of 20,000 feet.round directly beneath where we believe the crash site is is relatively flat and that also helps for debris recovery and potentially for the black box. as the storm comes in to the area, that can help move things around. as the white caps begin to pick up from the storm you see here, it will begin to be a secure a lot of the visibility around where those ships are located, making it very difficult to see where the ships would be down in what would be relatively clear water. they now will no longer have that, victor. >> the search for those black boxes and the fuselage is going on in those really unfavorable conditions. thank you very. >> investigators are hoping finding plane debris will quickly lead them to the wreckage itself and ultimately the plane's black boxes. let's make some sense of this with an expert on underwater search and exploration and co-led the search for the doomed 2009 air france flight. we know it took a couple of years to find the black boxes buried on the ocean f

that pinger runs out after 30 days.he battery only runs for 30 days, and you have to be under a mile range to even pick it up, and the sea conditions, you saw what the sea conditions are like in the mediterranean, can greatly distort signals so it gives a misreading of where the thing is. in the case of airfrance 447, it took two years to find the wreck, and now this is a familiar case of the data line, the ticking clock syndrome where people say there's 27 days, 26 days to find it. it's absurd. >> it is. listen, there's a reason you need the data to discover what brought planes down to prevent it from happening again. >> yes. you've got to know what happened and whether it can happen again. that's essential. >> no question. we have this da from that came from the plane, a sliding window sensor, smoke in the lavatory and avionics bay. you know about planes. looking at this, what does that tell you? >> well, i'd hate to read too much into it, but i think the significant thing here is that there was no may day call from t

. >> it's going to be in three stages, the pinger will narrow down the search. then you need to acoustically narrow the area. if it's rough terrain and geographically challenging that could offer own set of issues and then use robotic submersibles that have arms and can manipulate and go down there and actually look for cut, cover, recover the black boxes. this is not something that's going to happen fast there is a procedure in place to do it. if they are sending a robotic gear down, they may be -- sounds like it's -- a little bit ahead of its time acoustically is what they need to be focusing on now. that's not as easy as one would think, either. >> all right. would the ping, once you -- if you have located the ping, how big a field then do you have to look at? how far does this ping likely expand out that it can be heard? >> this is the trick. we're in deep water now. we're in 3,000 meters, 10,000 feet of water. when you get to about 1,000 meters, maybe 3,000 feet you get a layer that's throughout every ocean where sound can get up and get trapped and propaga

clock to locate the black boxes belonging to egyptair flight 804 before the batteries run down on the pinger to help crews find them. france joining the search as egypt rejects a claim by greece that the aircraft swerved moments before it vanished. let's go to ian lee in cairo. ian, you have greek investigators and egyptian investigators with different ideas of what happened before the crash. is that complicating things on the ground there? >> reporter: it is. we are seeing these two different theories, alison. two different claims. egyptians are saying the plane was flying normally at 37,000 feet. was a minute into egyptian air space when it disappeared. there was no swerving. it will be determined when they find those data recorders. they do have two submersibles looking for them. the french have one that can go to about 3,000 feet. that is not as deep as they believe the wreckage is which is more around 10,000 feet. it will be able to detect that ping from the black boxes. the egyptians have one as well which can go that deep. it has cameras and claws to manipulate the area around it. tha

the vessel searching for the pi pingers will almost have to be on top of them to get a solid fix. now, they're going to look at the wreckage floating. it may or may not tell you anything, because really, in this kind of investigation, if it was an observatiexplosive de the explosion takes place is the most important. and that will be further down the flight path. so they're going to have to not only search where the main wreckage is, but trace it back along the flight path, account for drift, and start searching for the first pieces off the plane. >> math is clearly a big part of this, tracing back mathematically where it had been before once you do see the pieces. peter, talk to me about the flight data recorder and voice recorder. the timeline, how long do they have to locate the devices? >> well, the clock is ticking. some of the older recorders have a 30 day battery, some of the newer recorders have a 90 day battery. egyptair should be able to tell us immediately what kind of batteries are on those devices. so the clock is ticking. >> tim, go ahead. >> yeah, peter is right. th

you cannot sweep an area listening to the pingers. >> that gets me to the next question for you. i got information handed to me. that is via the guardian, we have talked about, greece has joined the search and rescue operations. two aircraft, one c-1 hercules and one early warning aircraft have been dispatched. and helicopters are on standby on the island of carpathos. they do have quite of bit of manpower. listening to the list there, could you find the plane fairly quickly if you knew where it was last on radar? >> yes. because they are probably using their aerial assets they hunt submarines with. they could be dropping sonar buoys. if they have a fright going out there, they have acoustic devices to sweep the area listening for pingers for the cockpit voice recorder, assuming of course they went down in the water. so if they have a generalized area and because it's not as big as the indian ocean, they could probably narrow the search area relatively quickly. and then, of course, if they have any visual sights of debris that will help them hone in where the main debris may be r

as we know, we have 30 days on the pinger. here we are, approaching the second day. >> we all became familiar with that, with the maylasia flight. what it means for national security implications and more reaction, from here in paris, after this. >> i want to express by morning by the egyptair flight over the mediterranean. >> secretary of state john kerry offering the condolences of the united states of america, when we come back, were they expecting something like this in france? we'll dig into that and what donald trump and hillary clinton said about today's plane crash, we'll talk about that right after this. >>> when egyptair flight 804 went down, it went down amid heightened terror alert in this part of the world. we'll talk about this with laura haim, and also arthur lang. laura, let me start with you, is this something that officials in this country were expecting? >> yes, they were can'ting some terror to happen since the brussels airport attacks. again, we don't know what happened, we have to re-enforce that we reall

they have to start listening for the pingers from black boxes.ave a limited life span, they need to have redirected assets to recover the boxes so when they pick up the pingers, and they will, that assets are on station, ready to go. it is a race against the clock, and there's not a lot of time. >> we have data recorder for viewers. this is the pinger here. that's it? how much time? a month? 30 days? >> it is mandated 30 days. some have 90 days now. they're moving toward 90 day pingers, batteries which will give searchers a greater leeway, but many of them still have 30 day batteries, and that clock starts ticking. i watched it happen. >> we have some new information now. cnn can now report the name of the three crew members of egyptair flight 804, according to an official close to the investigation as well as a security source. these are the names. muhammad said shuk ar, the first officer next to the captain, the third was a purser on board the plane. tom fuentes, say you're investigating this crash in your old job as former assistant director t

the batteries and the pingers only good for 30 days. >> reporter: searchers call it the acoustic clockers run out, it will become much harder to find the egyptair jet cockpit voice and data recorders. officials say it's ability to find the plane is limited. the water is almost two miles deep in some parts of the search area. veteran searchers tell cnn, it's critical to get listening devices like high-tech towed pinger locators into the water. >> if these devices are not towed, if they're just single deployed devices, it's kind of like looking in the grand canyon at night with a flashlight for a dime. >> reporter: egyptian officials say they spotted egyptair flight 804 on radar for about a minute while it was inside egyptian air space. they say there was no radio contact with the cockpit. after about a minute on radar, they say, the plane disappeared. meantime, chilling audio has been released. the pilot of flight 804 making one of his last calls to air traffic control. as he speaks to a controller in zurich, the conversation is routine. nothing to indicate anything is wrong on board. >

something that seems impossible, we have seen the success of trying to find a black box without a pinger before and that was air france flight 447. rema remarkably, two years after it stopped ping ing the atlantic, off brazil, researchers found the black boxes and were able to bring them up and answer some of the important questions of what happened with that accident. it can be done but it takes a tremendous amount of effort, time. the french actually have a submarine good to 19,680 feet. they could actually send a submarine down there and begin looking. you're talking about a very involved operation that is very slow going and again, that silt that begins to cover it makes it that much harder to find the pieces ultimately needed to answer the pieces of what happened there. >> kerry sanders reporting for us. thanks so much. >>> up next, we turn to the breaking news, the race for 2016, as donald trump is set to speak at the nra convention. live after this. when a moment turns romantic why pause to take a pill? or stop to find a bathroom? cialis for daily use is approved to treat both ere

this pinger should work up to 20,000 feet. these pingers should work just fine. >> john cox, let me bring you in with information the greek defense minister provided based on military radar saying there was a 22,000-foot drop in this aircraft. it spun 90 degrees to the left and 360 degrees to the right. tom flagged for us in the last hour this very well could have been the plane going down after something catastrophic happened. what do those numbers tell you? >> well, i think first and foremost we need to validate that. and the fact that how they -- the radar actually acquired that information. military radar is very good, but it also has limitations. once the transponder stopped functioning, what they call a skin paint and it's painted -- the radar is painting the skin of the airplane itself. if this is a skin paint, is it just one large piece or are there multiple pieces? the rate of turn. is it something the airplane actually can do under control flight or is this an indication of the airplane having loss of control or not

so we've heard about pingers where we look for aircraft that have crashed in the water and then they stink and then you have so long to get to the wreckage before it dies. the elt, the emergency locator transmitter, when that goes off, that's normally due to an impact g force or g shock. that sets that off. >> that's why i was asking because there is some discream pen sees in the time frame. we have benjamin hall reporting that this distress call was made approximately 19 minutes before the plane disappeared from radar and we had other calls coming in that the plane disappeared from radar and then the distress call came in approximately two hours later. obviously we need to discover that if it was an automated call or a call placed from someone else or from the pilot himself. we do have information that there was a merchant ship captain that reported spotting a, quote, flame in the sky in this particular area. what did that tell you? >> we can't emphasize this enough. we are going to be getting inputs, data inputs. and they are going to be conflicting. is there a time zone play in th

they need the pinger locaters right now.submarines, french submarines that are there? >> they have listening devices and rescue vessels are probably on station or almost on station, but the clock is ticking. 25 days, it is an outrage that black boxes have not been retrofitted with batteries that extend beyond 30 days. that's not a weight issue or technical issue, it ought to be ordered by the aviation authorities as an emergency fix. >> david, what can we learn from debris found floating on the mediterranean? >> what i've seen on the debris, wolf, from these pictures is that there are pieces torn, it is clear that the aircraft came apart, whether it came apart in the air or on the ground, too early to tell, but it's proof positive that the aircraft is broken into pieces and under the ocean. >> in an investigation like this, does the fbi have a role, tom? >> probably not. probably not in this case. >> why? >> it is not an american aircraft, don't have american victims. >> the engines are u.s. made. >> yeah, but if americans g

large layers of distinct temperature variances can block pinger signals.ce of equipment is crucial, a towed pinger locator. we got a rare look where they're made. this device was used in the initial search for malaysia flight 370, helped lead to recovery of wreckage from air france flight 447 in the atlantic. the pinger locator can go 20,000 feet below the surface, it listens for the black box signal. >> how far can it be and pick it up. >> outside edge is two miles, mile and a half to two miles away it can detect the sound. the signal comes through the umbilical. here's a cable, runs through the umbilical, comes into our receiver unit. so we have a speaker on here, all the power buttons, can adjust the frequency it is looking for and out of this box we have a computer setup that graphically represents the signal you hear from the beacon. >> reporter: the search area is narrowed dramatically because airbus located signals from the emergency locator transmitter. the elt is an automatic distress signal beacon, they had three, including one in the tail. that

. >> this is different than the pingers on the black boxes underwater, right?ts are separate, the underwater signal from the black boxes is the pinger, those contain the flight recorders. elt is a small radio transmitter activated in the event of impact, signals are sent to satellites and then relayed to monitoring stations on the ground. once wreckage sinks and it is underwater, the signal is no longer able to reach the satellites. >> the black boxes, what's the timetable for the search for black boxes. >> reporter: still some time, 22 days left until the pinger signals go dead. the underwater search for the wreckage will begin in the coming days according to european officials. a french ship left for the search area, it is equipped with three underwater probes to listen and locate signals of the flight recorders, they look like this. they're also working to get a ship with an underwater robot and lift capacity to the area to lift up anything found underwater. 22 days until the pinger locor signals run out. >> brian todd reporting. thank you. >>> donald trump

. >> they're going to need to find the pingers. whether the equipment is there to do it yet, i have not heard anything on the news saying it is. we have 30 days or so when the pingers will be sending out a sound which could get them to where the black boxes are. >> you heard what kelly said. anything stand out for you at all? >> no, just completely routine. >> there are reports of smoke. i was speaking with another analyst yesterday. he was saying in all the years that he was a captain he had never had the concern of smoke, but that's new this weend. in your experience as a pilot, how often did you have smoke on a plane? >> never had it. >> never? >> no, no. when you get that sensor, you have apparently more than one sensor saying there's smoke. where there's smoke, there's fire. it could be smoke from overheating. they apparently lost a lot of the components they needed to fly the plane and lost control of it. >> we have that 90-degree turn that was reported and then a full 360. if you were to have an alarm go off, smoke in the la

the black box has a pinger that will send out a signal for up to 30 days. there were 66 people on board from paris to cairo. to see how their families are copio and search egyptair. >>> thank you. >>> police say he broke in to a house in the middle of the night and sexually assaulted the woman inside. now they released a sketch in hopes of catching him. kristin wright is in the northwest d.c. neighborhood where it happened. kristin? >> yeah, that's right. mostly everyone in this neighborhood knows about this sexual assault because they have an active listserv where they keep tabbing on everything and now there is a sketch they are watching closely. this is a sketch of the man d.c. police are calling a person of interest. in a sexual assault of a woman in her home in northwest. tonight people in the neighborhood are going about their friday night but things are not the same. >> it's really scary. i have an 18-year-old away at college and she's coming back. >> reporter: police say the man got in the woman's home tuesday after midnight. it is unclear if the un

days. >> this is a pinger. this is what we are looking for. in the middle of the atlantic ocean. >> but 30 days come and go and the flight recorders haven't been found. without the information they contain, the investigation into the cause of the crash is at a standstill. after nearly a year of searching under water, french investigators turn to the world leaders in ocean exploration for help, the massachusetts-based woods hole oceanographic institution. the scientists there, this isn't the first time they have searched the bottom of the atlantic for an ill-fated passenger vessel. >> we're the people that found the titanic. and it was through a collaboration with the french. here we are again. in many ways, it is history repeating itself. >> finding air france 447 is daunting. it's believed to be lost in one of the most hard to reach places on earth. >> in the middle of the ocean there's a mountain range. it's the greatest mountain range on earth. it's the mid ocean ridge. it's 50,000 miles long. it winds aroun

i never put a lot of faith in those pingers.almost perfect conditions, and the conditions here are far from perfect. especially since it's deep water. so you know, i think they're better off looking for the wreck itself. scouring the sea floor with s.o.n.a.r. and looking for the main body of the wreckage. >> thanks very much, gallo -- robert gallo for helping us there. we're going to leave this for a moment, because we're seeing more breaking thousand out of this protest outside this trump rally. these are live pictures. it appears the police have not been able to keep those two groups of protesters apart. that's been key. you have trump supporters there, you have trump protesters there. and when they get together, we have seen fists fly, we have seen bottles and rocks get thrown. and that's what you're seeing there right now. i'm still here with my panel, doug hy, formerly with the rnc. is this damaging for the republican party? >> i think it is damaging. one, this is an event our nominally is holding. two, something the entire

and the pinger is good for depps of up to 20,000 feet. out in the mediterranean sea, the focus is on finding more debris, suitcases, whatever pieces of the fuselage and trying to recover the victims but then honing in on the black boxes. how all of this relates to aviation security in the united states, the fbi saying that so far they don't see on the passenger manifest of known passengers any direct link to anybody on the u.s. terror watch list. nonetheless, as you would expect, they are very concerned about the overall security picture. here's the fbi director. >> we are very, very careful as a country to have learned lots of lessons since september 11th, including terrorist tradecraft. we are much safer than we were 15 years ago. we're never in a place we can be satisfied with that, but air travel in the united states, as against the terrorist threat, is far, far safer than it was 15 years ago. >> so as you know, the concern as it relates to this accident is the potential for somebody who to have smuggled on an explosive on to the plan

the pinger is your first. >> the black boxes ee meet a sound, we call it the pinger. this -- is that it in. >> this is the rov. it is a tool that once they found the wreckage on the bottom, and identify it, they'll send that down to actually help either bring pieces up, recover loved ones, or film with lights, and actually get right up close to the wreckage and deal with it. >> before they send in the rov, they have to, here, where the black boxes are, so in 10,000 feet of water, can a device hear the pinger through that. >> that's what it is designed for. it in that depth of water, you have to get it receiver, it is kind of a big ears listening for it. you have to lower it down, water is very dense, has lots of different layers. sounds can ricochet. you have to lower things down to it. that's your first tool to zero in on an area. once you find the area, you're going to then send down acous c acoustical -- >> i believe we have an illustration of that. so what does that do? >> it's a rapidly deployable system that they can throw on a boat, get out there and start look

debris and that will narrow the search to put the microphones in the water listening to the mostal pinger and we have 30 days to fine the black boxes. >> egyptair released names and photographs of the cockpit crew, the pilot and co-pilots with recent boyfriend now part of the investigation. >> today, the remain employees at the airport in paris are combing through the surveillance video and reviewing the prior stops in two trouble spots. >> in this is a bomb, you have to look at the whole security for all flights, where the aircraft comes from? what kind of bomb was it? >> a bomb is operating theory, no group has claimed responsible and officials have not found anyone on board with ties to terrorism. today, the administrator hinted changes could be coming to security when we learn more about egyptaair 804. >> thank you. a massive fire on a california pier engulfs a restaurant you may recognize, the must see video is next. >> taking the guess work out of planning your diet. >> developing news flames rip through a former restaurant on southern california's pier, with harbor patrol boats att

presumably right now the pinger is going off. navys and coast guard teams that are there in the mediterranean would be listening for that pinging sound and use that to try angina late and hone in on the black box. there's two black boxes. the flight data recorder which records hundreds of pieces of data about the performance of the aircraft over a period of time. so you would have literally thousands of pieces of data when you put it altogether. and then there's the cockpit voice recorder. it looks the same but it is recording not only the radio traffic between the controllers and the pilot, but there's also the internal conversations between the pilots. so all of that is being reported on the cvr and the thinking is that that would have recorded maybe the pilots saying we've got a problem. sometimes it's nothing more than them yelling an expletive, or it could be picking up the nanosecond sound of an explosion. that's what happened with metrojet. you may recall, the plane that was crashed and brought down presumably by a bomb ov

it's high-tech, heavy duty with the ability to pick up the signals from the pingers on the block boxes. the debris that has spotted could have drifted from that crash site. that submarine has gone out today. an egyptian submarine. while black boxes remain such a priority for investigators. they told our matt gutman last night that actually their priority right now is recovering those human remains to give the families some diane. >> molly, earlier we were hearing from experts talking about the signs that this looked like terrorism, now it seems like mechanical failure, what changed? >> reporter: that's right, diane. the french aviation investigation body has confirmed that messages, automated messages that are sent while the flight is still in flight confirm it's likely a mechanical failure. so, while some experts are saying that actually a bomb could have set off that fire the egyptians are still saying it's way too early to tell and we should wait for the investigation to complete before jumping to any conclusions. diane. >> good advice. molly hunter reporting live from alexandria, e

hopefully the underwater pingers will help them to identify, locate the flight data recorders, the blackboxes and bring them to the actual wreckage. but i think it's entirely possible in the coming hours we'll have reports from somebody there on the surface of the water reporting that they found debris. i'm sure you have again to the mediterranean through your travels with nbc and you know that there's a lot of stuff floating in the mediterranean. not only is it heavily traversed for shipping, and military purpose, but also all of these people who are trying to flee either libya or syria or whatever. and you have massive amounts of people on boats and, you know, many of those boats just kind of fall apart in the open waters. so discerning what is -- discerning what is real wreckage from a plane versus what is just the junk floating in the sea may be difficult. >> that may take some time, but there are 30 days of a shelf life, that battery, so that ping should be emanating for quite some time. making it a little bit easier at least for officials to find whatever records there may be. tom,

this is the underwater pinger attached to the recorder in this bracket and it is supposed to go off for a good 30 days if it's underwater and be good up to depths of 20,000 feet so that should be for the mediterranean sea just fine. you can imagine that the navys that are operating there in the mediterranean and the coast guard operations will all be listening for these pingers. since they have already got some debris on the surface of the sea, you can imagine that they'll probably be able to zero in on the rest of the fuselage and the wreckage and hopefully the rest of the black boxes relatively quickly. can we go back just for a moment, though, and i want to mention the video that you ran of the dog running through the plane there at charles de gaulle airport. they don't have enough dog teams to search every single plane and that's the bottom line, isn't it, because their concern all along is that this is not just a photo op, like you're seeing here, this is a daily, hourly, minute-by-minute challenge. they don't have enough dogs to sweep every single day, every single plane at the ai

the clock is ticking on finding the black boxes, because the pingers on the black boxes which are right here have only 25 days of battery life before they cut off. but the headline at this hour is that the plane may not have made any erratic turns or drops as previously reported by the greek military. lester? >> tom costello. tom, thanks. >>> a landmark moment during president obama's historic trip to vietnam. he announced today the u.s. is lifting the 50-year-long ban of sale of arms to that country. the latest sign of warming relations with america's one-time enemy. some lawmakers and activists wanted to see more human rights concessions before the embargo was lifted. >>> this week the governor of louisiana is expected to sign into law a so-called blue lives matter bill. the first of its kind, the bill would make it a hate crime to target officers and other first responders because of the uniforms they wear. nbc's gabe gutierrez has the details. >> reporter: it was the deadly ambush of two new york police officers in 2014, and then a texas sheriff's deputy last august, that prompted l

it's high-tech, heavy duty with the ability to pick up the signals from those pingers on the black boxesven that crash was four days ago, the debris that has been spotted could have drifted from that crash site and from where those black boxes are. that submarine has gone out today, it's an egyptian submarine. it has the ability to operate from 10,000 feet. but while black boxes remain such a priority for investigators, the minister of civil aviation told our matt gutman last night that actually their priority right now is recovering those human remains to give the families some closure. diane. >> and molly, you know, earlier we were hearing from experts talking about the signs that this looked like terrorism, now it seems more likely mechanical failure, what changed? >> reporter: that's right, diane, the french aviation investigation body has confirmed that those messages, automated messages that are sent while the flight is still in flight confirmed it's likely a mechanical failure. those messages indicate a fire in the lavatory and the electronic cabinet below the lavatory. so, while

and location, they have a pinger on them. if they get under water in that area, that's the thing i'm concerned about, do they really know where they have located them yet, because to locate them, they have to hear those pingers and get them and recover them. >> because at this point, it's very deep where the plane is. >> i heard it's up to 10,000 feet of water. >> how hard is that investigation? the weather's unpredictable. there are a lot of factors here. >> it will be very, very hard to get 10,000 feebt down to get thm because that's a great depth. in the malaysian crash there was only 5800 feet of water and this is almost twice that amount of water. >> so hard when so many families just want the answers to what happened. thank you for helping us better understand at least where we are at this moment. appreciate you being here. >>> a quick programming note. make sure you turn to fox news sunday tomorrow. homeland security secretary jeh johnson will talk with peter johnson followed by a one-on-one conversation with mike mcca

that what they have heard, what they may have picked up could be the underwater locator beacon, the pinger mounted on a bracket located on the flight data record he. and it is designed to ping for 30 days under water to give the searchers the ability to hone in on the signal. and kit continue to ping and operate at depths of 20,000 feet. i don't know what the depth is of the mediterranean sea but that would be encouraging for finding the debris. for finding this plane if in fact, you'll notice caveat. if this report is accurate. that they have in fact, if the egyptian military may have picked up some sort of an emergency locator beacon. you know, jose, we need to stress yet again. these are very early hours in this investigation. all we really know definitively is that a plane is missing. it lost radio contact at 2:30 a.m. local time. and that this plane has in fact crashed. where it crashed, we don't know. is this in fact a transmitter coming from the underwater beacon or the emergency locator? we don't know that either and this is a part of the world that information is often conflicting

detention devices and of course those are critical when they put them in the water to listen for the pingerstransmitters on the black boxes, the audio and data recorders that are submerged at the bottom of the stae rigea right now. nothing breaks if you will that breaks the story apart and lets us know what brought the plane down and every level there are things moving forward here. >> very quickly, "the new york times" over the weekend reported that this particular plane brought down had graffiti painted on it two years ago in arabic saying we will bring this plane down. what are authorities saying about that ominous perhaps coincidence or not? >> reporter: well, the minister of aviation said he wasn't aware of this until he read the newspaper article and then he wasn't minister of aviation when that happened several years ago and tried to steer the conversation from saying this is so important and focus on this saying, look, follow through the investigation. he didn't say that they were going to ignore this issue but this comes from the tail number on the plane and the connection between t
