donald trump is pulling a full steam ahead, no doubt, jim. >> jeff zeleny with the hillary clinton interview. i'm jim sciutto. wolf blitzer will be back in "the situation room" to him. after this, erin burnett "outfront," starts right now. "outfront" next. breaking news. an intense search and rescue operation for egyptair 804. that plane missing. 66 on board. one early theory, a terror attack. what happened to the plane, where is it? and u.s. officials working on the theory it was a bomb. who planted it? how did it actually get on board? was it in paris? plus, los angeles international airport under heightened security alert tonight. let's go "outfront." good evening. i'm erin burnett. "outfront" tonight, the breaking news. a massive search under way tonight for any sign of egyptair

flight 804. the plane, 66 on board, is still missing. it disappeared from radar nearly 24 hours ago. let me repeat. it's still missing. they haven't found it yet. u.s. officials are working on the early theory that the plane was taken down by a bomb. so far, no group, though, has come forward to claim responsibility. and just in at this moment to cnn, the names of the highly experienced crew. captain mohamed syed and his first officer, ahmed asem. the airbus a-20 calling from 37,000 feet in the sky. swerving wildly, plunging thousands of feet in just minutes, according to greece's defense minister. the paris to cairo flight took off from charles de gaulle airport, the main airport in paris. it is the second-largest airport in europe. and late today, one of the most heavily trafficked airports in the world, los angeles international, dramatically ramping up security.

we are covering this fast-breaking story. there are so many angles. we are learning more at every minute. we begin with arwa damon "outfront" tonight in cairo. what are sources telling you? >> reporter: well, they're still trying to piece together exactly what took place. there was a little bit of hope earlier in the day, erin, that perhaps the plane had been found. but then the vice president of egyptair said that he was mistaken and a lot of questions are still being asked. u.s. officials tell cnn, they believe a bomb brought down egyptair flight 804. killing all 66 on board. officials basing their early theory on circumstantial evidence. a routine flight manned by an experienced crew, suddenly falling from the sky. egyptian authorities aren't ruling out anything.

>> we do not deny there is a possibility of terrorism. >> reporter: 11:09 wednesday night. egyptair, 804, lifts off from charles de gaulle airport for the four-hour flight to cairo. on board, 66 passengers from a dozen countries. a crew of seven. three security personnel. and among the passengers, a child. and two infants. 1:24 a.m., the airbus enters greek air space. athens air traffic control makes routine contact. 24 minutes later, another routine check. the pilot reportedly cheerful. the weather, clear. and calm. at 2:27, less than an hour later, athens controllers try to contact flight 804. but despite repeated calls, radio silence from the cockpit. at 2:29 a.m., while cruising at

37,000 feet, radar indicates the plane began a series of wild maneuvers. first swerving 90 degrees left. then a full circle. 360 degrees to the right. all the while, plunging from 37,000 to 10,000. the plane disappears from radar. >> translator: after the plane was lost, there were trials to get in contact with the plane again. but they failed. >> reporter: the aircraft passed through airports in tunisia and air treea the day before. then swept through paris prior to takeoff. the passenger manifest, erin, we i understand, were cross-checked with any sort of other terrorist lists that may be out there. both before the passengers had boarded the flight, we understand, as well as after the flight went missing. the names of the crew and the

three security officers on board were also cross-checked. this is part of a routine undertaking that egyptair and many other airlines now have in place, because of an overall heightened state of security. and there were no red flags that were raised before the ill-fated flight took off. >> all right. arwa, thank you very much. arwa live in cairo tonight. u.s. officials are scouring their system, also going through the satellite data to see what happened at the moment of, well, what is the right word? impact, explosion? looking for any indication that egyptair flight 804 was brought down by a bomb. evan perez is "outfront" in washington. evan, officials tonight, as you have been reporting, talking about what they think could be very significant. >> reporter: that's right, erin. one of the things they're looking at is the fact there simply was no may day. no distress call made by the pilots on board this aircraft. why that's significant, we're

talking about a modern aircraft that has redundancies. redundant systems that would allow time if there is something happening on the aircraft, perhaps even if someone is trying to break into the cockpit. these pilots would have had time to make that call. none of it was made. so that's one reason why authorities are focusing on the possibility of terrorism, of a possible bomb. again, nothing has been ruled out at this point. but this is where they're beginning. it's an operating theory they have before they can look at the wreckage of this aircraft to try to determine what happened. >> part of the fear here is, evan, as of yet, no one, no group has claimed responsibility. raising a lot of questions. because they just don't know. and they don't know if more things -- if this was a group, are there more things planned. is there heightened concern right now? >> reporter: there is. there is a tremendous concern in western europe. this summer, erin, you remember last summer here in the united states, there was this heightened state of alert about the possibility of terror attacks in the united states. i'm told by authorities, both in

europe -- top french officials, u.s. officials. they believe this summer is something they are very, very concerned about. we have seen terrorist attacks in brussels, paris in the last few months. we know next month we have big soccer championships in france. it's a very big concern about the rise of extremist groups in western europe. and the possibility of some major attacks coming in western cities in western europe. >> all right. thank you very much, evan perez. "outfront" tonight, mary schiavo, department of transportation. david susie, safety inspector. miles o'brien, aviation analyst. and justin green, former military pilot. good to have all of you with us. let me just start with you, mary. this -- is this really a game-changer? you have now seen a plane that they now think possibly brought down by a bomb, taking off from the second busiest airport in europe, paris' main airport, charles de gaulle.

>> yes, it's a game-changer, because everyone has been on a heightened state of alert. the united states demanded increased security on planes leaving europe to come to the united states back in 2014. after the attacks in paris and brussels they went on high alert. they supposedly scrubbed the airport. and so if whatever caused this plane to go down, if it was terrorism or criminal activity, got through all of that, and got through undetected and was successful in bringing down a plane, this is a new level of terror. >> and david soucie, would you agree this has changed the game, possibly? >> i have. security has always been a game of cat and mouse. of chasing your tail, however you want to put this. but until you see that threat, until you know what it is, it's -- at this level of this complexity, it's virtually impossible to try to guess ahead and prepare and prevent. we have -- we're continually learning and moving forward. although there are mitigation things happening all of the time, the airlines are safe. i don't want to put false threats -- false worry out there

for anybody. but it is constantly learning and getting better and this really changes the game of complexity. >> and miles, another big appointment here is the mystery. at this point, just the mystery. they're saying they think there was an explosion that it was likely a bomb. but yet no proof of that, no plane tonight. 4 hours almost. and there is no plane. no claim of responsibility. >> yes. when we start talking about terrorism as a possibility, you would expect a claim, wouldn't you, by now. but we have a lot of missing pieces, literally. and figuratively right now. and part what have we're thinking about here is this time line. there's this two-minute period of time where they weren't responding to air traffic control. and in that course of that time, the plane began its erratic maneuvers and ultimately disappeared from radar. what was going on in there? was that nonresponse part of some sort of struggle on the plane or some deliberate intent not to respond? >> because you're saying the time line that arwa just went

through, they reached out to the plane, time went by, then the erratic moves started. so there was time. >> yes. it wasn't instantaneous. or so it seems. however, an alternative theory here could be they were just in a bad radio zone. they couldn't here air traffic control or air traffic control could not hear them. because that first turn, that 90-degree turn is what you would do if you were doing an emergency rapid descent after a decompression. you take a turn off the airway so you don't fly into another aircraft below you. so was it possible they were doing a standard operating procedure, emergency descent after some sort of, you know, explosion, perhaps. and were they perhaps -- issuing may day calls all the way down and no one heard them. >> that's the thing, just the mystery. we do not know at this time. although you do, of course, have intelligence agencies from cairo to the u.s. saying they are leaning towards a bomb towards terror. but yet as miles is pointing out, it could be something else. >> yeah, there are too many ifs right now. and too many possibilities. so if this was a terrorist

attack, i agree with mary. that you know, you had an airport that was on heightened security. you have an airline that should be on heightened security. you have a lot of threat, you know, i'm not a threat expert. but you have certainly enough notice. >> we do know. i mean, i was in paris. even those groups we were talking about. successfully pulled off the attacks in brussels at a brussels airport and in paris, they were trying to strike charles de gaulle. >> so if it was a successful terrorist attack, it would have had to be based on what we know now. would have had to have been a relatively sophisticated one. that is a game-changer. but that's a big if. >> and bob baer, what is your take on this? that something like this could have happened. that at this moment almost 24 hours later, we still have so many questions we do not know. including where is the plane. >> well, i think everybody would agree, an airbus just doesn't come out of the air like that. it's very, very rare. this is egypt, we're talking about france. it's an airport that's been

under threat for some time. they fired a dozen people last year with jihadi connections. that whole airport has got problems with its staff. the french are under threat. so if you start adding up what we know for certain, it does point to terrorism. and the question is, are we going to be able to figure this out. and where was the bomb put on? a sophisticated bomb maker could have put this on in cairo, got it to paris with the barometric switch and timers and the rest of it. this could be done and didn't have it explode on the way back. the question is, was it put on paris -- in paris, and if it was, that really is a game-changer. >> would be a complete game-changer and terrifying for people watching around the world. all right. we're going to take a break. next, we go inside the final moments of that flight. exactly what we know. in those crucial seconds, which way did it turn? then it turned. we're going to show you exactly how egyptair 804 went down. plus, those major security concerns at charles de gaulle

airport. reports of radical slammists working there. some of them given -- security clearances taken away but still allowed to work at the airport. we're live with the latest. and donald trump called to the terror attack before there was any evidence. did he jump the gun? what's it like to be in good hands? like finding new ways

to be taken care of. home, car, life insurance obviously, ohhh... but with added touches you can't get everywhere else, like claim free rewards... or safe driving bonus checks. even a claim satisfaction guaranteeeeeeeeeee! in means protection plus unique extras only from an expert allstate agent. it's good to be in, good hands.

introduces new, easy-to-swallow tablets. so now, there are more ways, for more people... to experience... complete protection from frequent heartburn. nexium 24hr. the easy-to-swallow tablet is here. safety doesn't come in a box. it's not a banner that goes on a wall. it's not something you do now and then. or when it's convenient. it's using state-of-the-art simulators to better prepare for any situation.

it's giving offshore teams onshore support. and it's empowering anyone to stop a job if something doesn't seem right. at bp, safety is never being satisfied. and always working to be better. breaking news in the crash of egyptair flight 804. right now officials analyzing every second of the plane's final moments to figure out what happened. at this hour, nothing has been ruled out. but those last minutes offer very revealing clues. tom foreman is "outfront." tom, what do you know at this moment about these crucial final minutes for this plane? >> what i know, erin, many of

the clues come from what happened and from what didn't happen. here's what we know. the plane took off right after 11:00 at night, from up here in france. it should have been a routine four-hour flight to cairo. left at 11:09. we know by 1:24, it was in greek air space. 1:24 in the morning. at 1:48, a greek air traffic controller spoke to the pilot who he said was cheerful. and then about 40 minutes later, as the plane passed from greek air space into egyptian air space, they couldn't contact it any more. and about two minutes after that, then they described these wild turns and gyrations of the plane as it rapidly loses altitude and then it disappears. we have a combination of what happened here that they know was going on, and all the things that didn't happen before when it seemed to be normal and no sign of anything going wrong, erin. they have to think about all of that and ask, what does it mean? >> so we're going to be talking in a moment with our experts about their ideas about what

could have caused this. but from what you have been looking at, tom, what could cause a plane to do what it did? you do a 90-degree turn and then you're followed by a 360-degree turn. and then a plunge. >> well, first of all, let's bring in a model of the plane here and talk about this some of the this may not be those turns. this, in fact, could be sort of artifacts of how radar is trying to read a plane that is tearing up in flight. we don't know. we'll have to find out if it was actually the plane doing all of that or parts doing it or something like that. but here are some possibilities. they always look at weather in circumstances like this. it is possible for weather to make a plane like this fail in flight. the problem with that theory in this case, there was no known weather in the area. it seemed to be a fine night for flying. so they have to look at that. they can push it sort of to the back as they're looking right now. what about a structural failure? it has been known that there are cases where perhaps a wing actually falls off a plane like this. it's traveling 540 miles per hour. maybe something on the tail

fails on an engine develops some severe problem. but again, there is no indication that this plane was having a problem and it was cruising altitude. it was doing what is one of the most -- one of the least stressful things for a plane like this. there's no real reason to think there was some sort of catastrophic structural failure, or that that would have kept the pilots from reaching out to the tower and saying we've got a problem. that's one of the reasons why they're looking so much at a deliberate act. the idea that maybe somebody on the ground did something to this plane, or let's open the plane up and talk about who is inside. what about the question of the people on board? we know there are two people up in the cockpit of this plane. we know there were five crew members back in the cabin. we know there were three security people in the cabin. we marked them here in red. and, of course, we have all of the passengers back here we marked in yellow. we don't know exactly whether they were seated on the plane. we know the plane wasn't full. but investigators now have to look at all of the people. and one of the reasons we're

talking about it being a deliberate act, so far there has been nothing to support the idea that it was something else. they have to look at all of that, but this is one of the reaches that a deliberate act keeps coming to the foreground. erin? >> thank you very much, tom foreman. so we want to talk about more now with my panel. mary, let me start with you on this. because you believe that one of the most terrifying things about what we are seeing right now is that this possibly could have been a test. or a dry run. >> that's right. i think probably the most terrifying prospect is if this was a -- dry run for something like -- had two plots. one was in 2006, and that was the plot, al qaeda, where they were going to take seven planes from great britain headed to the united states and blow them up over the ocean. luckily, that plot was foiled. but that is why we have the liquids ban at the airport. they were going to use liquid bombs that would be constructed after they got through security and the other is, of course, the

1995 bow jinka plot which was supposed to take a dozen airliners over the pacific. they did a rest run with the plane and were able to get a bomb on board and blow it up. they planned that, wanted it to happen over the water so no one would find out. that's one reason why it could be terror. yet there is no responsibility or credit taken, because there is something else that they want to plan in the future. >> and bob, does this make sense to you, especially in light of what evan perez was just reporting, which is that u.s. officials are now concerned about travel this summer? >> oh, i think so, absolutely. these groups, whether it's al qaeda or the islamic state, are after airplanes. they're looking to recruit people in airports. they're looking to modify bombs to get them on airplanes. you can take this explosive, home-made explosive, tatp and put it inside of a samsonite, for instance. they're working on this all of the time. and this may be a dry run. but they don't necessarily

follow a book. they may claim it a week from now with some sort of proof. we have to wait to see. as we were just talking about, these planes are vulnerable. >> and you know, which, of course, with metro jet, they ended up coming out with a video of what they say was the explosion when they finally claimed credit and they took a little while to do so. miles, your view is this possibly could have been humans. whether it was the pilots or someone who came into the cockpit. >> yes, i think deliberate act. let's go with deliberate act. i think we have established that one way or another. but the evidence could support two ways this could be. first of all, a terrorist plants a bomb. in that scenario, for whatever reason, the crew is unable to make a radio call. there is bad radio transmissions, whatever the case may be. they have a rapid decompression, they follow the standard operating procedures, take the 90-degree turn off the airway. they try to stabilize the craft at 10,000 feet but are unable to do so because the plane is structural compromised. the other option that the evidence also supports --

>> yeah. >> is a deliberate act by one or both of the crew members. and maybe more likely one. because -- >> one had -- there was that cheerful, as they describe it, handoff from someone in the cockpit to air traffic control. >> and what if one of the crew members took it upon himself and we have seen precedent for this, including with egyptair 990 in 1999, germanwings more recently. what if the nonresponse by air traffic control was a deliberate silencing of the radio, and one or both of the crew members are in cahoots with that. and then what if those erratic maneuvers were somehow indicative of some kind of struggle in the cockpit. could be. >> david soucie? >> yeah, i think it's important to point out the fact we talked about vulnerabilities before and the possibility it could be going on for the next one. so the way to plug those holes, the way to stop that from happening is to go back and look at not only everyone that was on the aircraft, like tom foreman had pointed out. but everyone who touched that aircraft. everyone had access to it.

so right now investigators on the ground are doing just that. they're looking back to see who is on shift. who called in sick, what day. who may have had the accident, the access to the aircraft, and acted peculiar with those videos, so they're reviewing videos, seeing that. they're trying to plug those holes, safety is a bunch of swiss cheese and you want to line up the holes. >> and miles, a question to you. how significant is it they haven't found the plane? i mean, you know, this is the mediterranean. it's not the pacific ocean. we know it's there. i mean, they haven't found it. it's been almost 24 hours. >> not the certain indian ocean and not the north atlantic. air 447. they found the vertical stabilizer four days later, if i have or take. it's a still a pretty big sea. let's give it a little more time. is there a lot of shipping traffic there. they have a pretty good fix on where the aircraft was. let's give that 24 more hours before we get too concerned about that. >> all right. all going to stay with me. and next, charles de gaulle airport, one of the world's

busiest. as our guests are saying, a complete game-changer, if a terrorist there was able to plant a bomb on a plane, are terrorists among the employees at de gaulle right now. and u.s. officials telling cnn they're concerned about usair travel this summer. security is ramped up at l.a.x., los angeles international tonight. our report, next. you mow, it's how well you mow fast. it's not how fast you mow, it's how well you mow fast. even if it doesn't catch on, doesn't mean it's not true. the john deere ztrak z535m. it's how well you mow fast. there's no one no one surface...e. no one speed... no one way of driving on each and every road. but there is one car that can conquer them all. the mercedes-benz c-class. five driving modes let you customize the steering, shift points, and suspension to fit the mood you're in... and the road you're on. the 2016 c-class.

breaking news. back with our special coverage of the disappearance of egyptair flight 804. the flight original natured from paris, charles de gaulle airport, one of the world's busiest. more than 60 million people pass through that airport every single year. and it has been the focus of major security concerns. atika shubt on the ground for us tonight. we know the groups in paris covering the terror attacks there, had been aim to go strike de gaulle. what can you tell us about the concerns at de gaulle right now? >> reporter: absolutely. i mean, airport authorities here are known for quite a while this is a prime terror target. but what they have really been focusing on in the last few months are those employees that have access to those security

areas. there's about 85,000 employees here at charlie de gaulle and orally airport that have access to restricted areas and concerns to what links to radical islamic groups they have. and in fact, in december, airport authorities actually removed up to 70 people from their jobs, took away their security passes, precisely because of those security fears. and now what they do is do periodic and random checks of personnel security lockers. and those kinds of security checks you and i go through to get on to a plane where no liquids, have our laptops checked, all of that also applies to those personnel going into those restrict restricted . it's already a high state of alert, even before what happened to today's flight. but now investigators are looking at this even more closely. >> all right, atika shubert, thank you very much, live from paris, charles de gaulle at this hour. the terror attacks on airplanes are happening more

often. in the past year an explosion brought down a russian passenger jet in egypt. a bomb hidden in a laptop near mowing deesha. miguel marquez is "outfront." >> reporter: airline security under scrutiny again after egyptair flight 804 abruptly descends mid flight into the mediterranean. worldwide over the last five years, there have been nine hijackings, two bombings, two suicides and one mystery in what brought down malaysian airlines flight 370. egypt has been targeted before. authorities today more forthcoming than ever. >> terror exists everywhere. it's definitely something that we are concerned about. >> reporter: but when russian airliner, metro jet 9268 was brought down by a home made terrorist bomb placed in the luggage hold, killing all 224 aboard, it took egyptian authorities four months to admit it. egyptair itself has also been

targeted. in march, a hijacker claiming he had an explosive belt forced flight 181 to land in cyprus. he was arrested, no one was injured. and in february, another bomb aboard a somali airliner, flight 159. this time two airport workers suspected of sneaking a bomb into a laptop through security and giving it to a third accomplice who carried it on to the plane. the bomb blew a hole in the side of the plane, which was able to land safely. the only fatality was the man holding the device. the incident raised enormous security concerns then. egyptair flight 804 raises new concerns today. >> if this is indeed a terrorist act, there's a hole. where did that hole start? you know, did it start on the original departure? >> reporter: another security gap, pilot suicide. in march 2015, the co pilot of germanwings flight 9525 suffering depression crashed his plane into the french alps.

150 people died. egyptair too has a history with one of its pilots possibly bringing down his own plane. in 1999, flight 990 via jfk crashed into the atlantic. 60 miles south of massachusetts, killing all 217 on board. the national transportation safety board concluded, it was a deliberate act by the first officer that downed the plane. egyptian authorities came to a different conclusion. citing mechanical failure of the boeing 767. flight 804 could still have been brought down by a mechanical failure. but points to sabotage at the moment. if that is the case, the question is how did a terrorist bring a flight like this down mid air? forbid that security lapse was in paris. erin? >> god forbid. thank you very much, miguel. bob baer, mary schiavo back with

me, along with paul cruickshank, the general of combatting terrorism at west point. let me start with you, paul. what do you know now? >> well, erin, at this point, there is no solid evidence whatsoever that this was, in fact, terrorism. there's been some speculation from greek -- the egyptians, there's been some speculation from u.s. sources. but no solid evidence yet that this is terrorism. and there's been no claim of responsibility whatsoever from any terrorist group. the silence from isis has been deafening. when they brought down that russian airliner in october, over the sinai peninsula, they put out responsibility within a few hours. five hours. they're very trigger-happy with thes claims of the responsibility. but almost 24 hours into this event, no claim of responsibility, erin, from isis. so we really don't have anything to back up the idea that this is

terrorism at this point. >> right. no, of course. although it did take them a little bit of time with the metro jet, as well. bob baer, let me ask you. your theory is a bomb is very possible, and you have an idea of, you know, in the metro jet case, as you heard miguel reporting, isis says it was basically a soda can, a home made bomb they were able to put in the luggage, checked luggage, get this put on a plane by a luggage worker. in this case, if you think it was a bomb, it was very different. how so? >> well, i mean, you can take -- make these bombs very small, the size of an iphone. even a couple ounces. and if you put them inside the cockpit, assuming you have access to that, the cleaning staff or whatever, it's easy to disable one of these airplanes, or put it on the skin in the overhead. which is more complicated. you don't need a lot of explosives. you -- simply -- what's called the zipper effect, cuts a small hole because of the pressure.

the hole will expand and will cut the airplane in half. so, of course, these are all theories. and i support the possibility of a struggle in the cockpit. 1999. i have listened to the tape. the first officer. and he was clearly taking the airplane down on -- >> that was the egyptair -- suicide off the coast of new york. >> exactly. that was -- in my mind, it's clear it was a suicide. and probably related to islam, as well. right now, we don't have any evidence about this, but again, i go back to paris. it's impossible for an airport like charles de gaulle to have 100% security. they can't keep track of everybody. and if the bombs are so small, anybody could carry these in with access to the airplane, including the cleaning staff. >> mary, how many people come in contact with the plane? when you're talking about a plane like this at charles de gaulle, again, we can't overstate the significance of this. i mean, it would be incredible if this actually happened and was placed in at charles de gaulle. but how many people would

possibly have access to a plane like this? to an airbus on the tarmac? >> well, actually, hands on the plane, probably a couple dozen. but remember, there's sort of extension hands, if you will, of people who prepare the food carts, who check the bags in, who might have handled the previous flights so literally if you put all of the people that go into putting things on to the plane, even if their hands don't put it on to the plane themselves, hundreds. >> i mean, it is pretty incredible. and bob baer, what do you make of the point that paul was making, that there has been no claim of responsibility. mary thinks it could be significant, because it could mean that this is possibly a dry run. that this is a test and they don't want to reveal themselves pause they have something much, much worse in store. >> it could be a test. they could be testing charles de gaulle or even cairo airport. but paul is right. it's normal for these people to claim responsibility. but, again, there's no rule book for terrorists. and, you know, it may come later, a couple days.

or maybe never. it just all depends. >> all right. thank you all very much. "outfront" next, u.s. officials warning about air travel this summer. tonight, los angeles international airport, this evening, is now on a heightened alert. we'll tell you exactly why our american flyers at risk. we're live there next. and we're going to show you live pictures. donald trump has a fund-raiser in new jersey tonight. he says the terror attack took down egypt flight 804. does he have any evidence? the pursuit of healthier. it begins from the second we're born. because, healthier doesn't happen all by itself. it needs to be earned every day. using wellness to keep away illness. and believing a single life can be made better by millions of others. as a health services and innovation company optum powers modern healthcare by connecting every part of it. so while the world keeps searching for healthier we're here to make healthier happen.

breaking news tonight. heightened security at los angeles international airport. one of the busiest in the united states. as american officials tell cnn want to, they are very concerned about air travel this summer. all paul, how concerned are officials? >> well, concerned enough that the l.a. airport police told me they, of course, ramped up security here, and especially their counterterrorism security. one of the things they intended to do, we saw this near the entrance to l.a.x., they were going to make their emergency services unit, their s.w.a.t.

unit, much more visible. they say that is indeed quite a deterrent to any counterterrorism -- any terrorism activity. they were also pointing out to us, it's not uncommon for them to make adjustments based on chatter or any news information, such as the disappearance of the egypt flight. and they add that there is no credible threat they have heard directly to l.a.x. or any of its affiliated airports. nevertheless, they are urging anyone who sees something to say something, erin. >> are people -- are people nervous there that you've talked to? >> reporter: yes, the people i talked to are not really nervous. they said they noticed that security has been sort of picked up a notch and they rather like that. they say they're glad to see everything here is going calm. you'll see mind me, they're getting ready for their international flights and overall, they say it's extremely sad what happened, but they're glad to see things are going smoothly here at l.a.x., erin. >> paul, thank you very much. and now back with me, aviation analyst and pilot, miles

o'brien. paul talking about the heightened alert at los angeles international. the s.w.a.t. team walking around. your concern is not what we the passengers see. when we're walking into the airport. it's the other side of the security line. >> yeah, i call it the back door of the airport. i'm not as concerned about the front door, trafficly. to me, that's like security theatre, having people walk around with automatic weapons and dogs. the real threat, in my view, are the employers. the caterers, the people who are not screened, not taking off their shoes. we have seen all kinds of evidence in recent years that the back -- doors of these airports are -- leak like a sieve, including bun r gun within hundredors and drug runs. if you want to get stuff on planes, you can. so to the extent they are addressing the wrong problem, i worry, because let's face it, resources are limited. >> resources are limited. and you have the u.s. now warning about fear of air travel this summer. a significant statement. >> fear of air travel. and here we have -- expected huge surge of travel.

the tsa understaffed at the front door of the airport. and you have to wonder where this is headed. i would like to see better focus in this country, more resources put on keeping that -- the employee side of the fence a little more tightly secured. >> all right. miles o'brien, thank you. and next, donald trump quick to called today's crash a terror attack. hillary clinton weighing in hours later. what she is saying in our exclusive cnn interview, next. we're out ink.nk. not ink. getting ink doesn't have to be painful. staples just cut ink and toner prices. add in our 110% price match guarantee and our prices are unbeatable. staples. make more happen.

ready for a new chapter? talk to your rheumatologist. this is humira at work. breaking news tonight, the crash of egyptair flight 804. moments ago, donald trump wrapping up a campaign rally with chris christie in new jersey leaving no doubt about what he believes happened to the plane. >> today we had a terrible tragedy, a plane got blown out of the sky, and if anybody thinks it wasn't blown out of the sky, you're 100% wrong, folks. >> this comes hours after clinton weighed in on the plane crash, and why she says trump is

not qualified to be president. in an exclusive interview with our own chris cuomo. >> well, chris, it does appear it was an act of terrorism, exactly how, of course the investigation will have to determine, but it once again shines a bright light on the threats that we face from organized terror groups, isis of course and other networks of terrorists that have to be hunted down and defeated, and i think it reinforces the need for american leadership, for the kind of smart, steady leadership that only america can provide working with our allies, our partners, our friends in europe, the middle east and elsewhere. >> how do you fight the perception that we look weak. trump this morning was out hot and early on twitter when this happened saying looks like another act of terror. more proof that we're weak. we have to be strong. there's a lot of hate and anger out there. he is channeling the perception that a situation like this fuels which is we are weak, they can

take our planes when they want, the russians, the chinese can scare our military when they want and america does nothing. how do you answer that? >> well, first of all he says a lot of things, he says a lot of things that are provocative that actually make the important task of building this coalition, bringing everybody to the table and defeating terrorism more difficult. >> why? >> for example, when he says bar all muslims from coming to the united states, that sends a signal to majority muslim nations, many of whom we have to work with in order to defeat terrorism, some of whom are among our strongest allies in this fight. >> let me ask you, do you think that donald trump is qualified to be president? >> no, i do not. and i think in this past week whether it is attacking great britain, praising the leader of north korea, a despotic leader,

whether it is saying pull out of nato, let other countries have nuclear weapons, the kinds of positions he is stating and consequences of those positions, and even the consequences of his statements are not just offensive to people, they're potentially dangerous. >> how so? politicians talk, madam secretary. they say things, but once they get in office, people believe nothing will be that different. >> well, when you run for president of the united states, the entire world is listening and watching. when you say we're going to bar all muslims, you're sending a message to the muslim world and also sending a message to the terrorists because we now do have evidence, we have seen how tru donald trump is being used as a recruiter for more people to join the cause of terrorism, so i think if you go through many

of his irresponsible, reckless, dangerous comments, it is not just somebody saying something off the cuff. we all misstate things, we all may not be as careful in phrasing what we say. this is a pattern. it is a pattern that has gone on now for months and it is a pattern that adds up in my opinion having watched presidents, having seen the incredibly difficult work that they do and the decisions that they have to make, the thinking that goes in, sitting in the situation room, do we go after bin laden or not. was it a clear, easy choice? of course not, did it have to be carefully parsed and analyzed, and we all gave our opinions but it was up to the president to decide. i know how hard this job is and i know that we need steadiness as well as strength and smarts in it and i have concluded he is

not qualified to be president of the united states. >> outfront now, executive editor for politics, mark preston. let me start where she finished. she criticized him a lot, said very negative things about him before. she has never come out and said he is unqualified to be president of the united states. today, offered it up. >> timing is everything. the airplane goes down, they're trying to figure out what happened, people think it is terrorism, she goes out and says she doesn't think he is qualified, that he is divisive, dangerous, and she reiterates he is used as a recruiter for isis. timing is everything. >> on a day an airplane goes down she said that. here's the thing, you had a poll showing him ahead in national polls. today she's ahead, but the gap is narrowing significantly. after paris, after san bernardino, donald trump went up in the polls. she has got to be feeling that. >> no doubt. his rhetoric is so strong and very simple. he goes out and says look at the

terror, look at the anger. i am going to stop it. i am the person who can stop it. i looked at numbers as well, the latest cnn orc poll shows hillary clinton has a huge lead over donald trump when it comes to the issue of foreign policy. when you boil down to the issue of terror, she only leads donald trump by five points. that's got to be concerning to her. >> that's got to be extremely concerning to her. yet today what you saw this morning was donald trump out first on twitter. just heard him speak, of course, with chris christie, but this morning, out before anybody else, this is an act of terror. she's trying to say that's irresponsible. he is trying to sell it as coming from a position of strength, being unafraid to call it like it is. and of course the question is how will the undecideds see it, how will foreign policy establishment see it. >> and what happens when he starts to get intelligence briefings. when he gets those key briefings as she does, does he come out and use that to try to bolster

his argument that he is the better person to take that on. >> they both get those when they're formally the nominee. >> looking about august 1st. it is amazing. >> it is incredible when we realize the race we are about to see. thank you very much, mark preston. we'll be right back. ♪ [female narrator] you listen when your body says: "i'm tired." or, "i'm hungry." what if your body said something else might be wrong? gynecologic cancers - cervical, ovarian and uterine cancers - have symptoms. so pay attention. if your body says something may be wrong.... please listen if it goes on for two weeks, see a doctor, it may be nothing but find out. learn the symptoms. get the inside knowledge about gynecologic cancers.
