Tonight u. S. And french intelligence are comparing passengers to known key to what happened. Conferrings between the flight crew and any alarms or sounds or explosions. The flight data recorder should contain thousands of pieces of data. British citizen richard ozmond was on board, his brother, richard allister. I never expected to wake up to this. Reporter back live here in paris, im joined by my friend and colleague laura hanes, shes the continue for the airline here. It would be nice to see you under better circumstances. Lets start with the climate right now in paris, we know that the plane itself took off just after 11 00 local time wednesday, but i know you have some information on what the French Police had to do with this . You had a lot of demonstrations against the police in paris. Two days ago a Police Department was burned. And the people are angry, we la. Whats happening with the plane, we dont know what happened with the plane, but this was a very important moment because the police were saying we cant go to the airports and we cannot protect the planes. Lets talk about the latest announcement, that the french president would be leading the investigation to a certain extent. What are you hear . I know youve got a lot of sources here in this country, at which point do they feel like this is probably terrorism . They feel it, but of course, theyre not sure, theyre really looking at every possibility. At this moment Francois Hollande really wants to have all elements that the egyptians know, this is a very important element. The other element is they know who was on the plane, there was saudis on the plane, three men were on the plane to protect someone. Who was this person. They other also looking at a man who was an iraqi person, so theyre looking at really the nationality and the job of the passengers in the plane. Of the 55 passengers who were on board, were told the lions share of them were from egypt. 15 from your country, you mentioned three people who were on board to provide security of some sort, is that customary . Apparently this flight for egyptair was a sensitive flight, and people i smoke wipoke with know what did the egyptians know . Why did they put three men in the plane. Thank you for staying up so very late here in paris. I want to bring in john goulia now, a former ntsb agent. At this point what do we know that the pilots did in the last moments here . We were sold that there were some sudden turns, 90degree turns before that plane plummeted to 30,000 feet, to 10,000 feet, where they lost contact with radar. What does that information alone tell you . We know it had to be a catastrophic event, whether it was computers going haywire, the human element. We have had pilots who made wro wrong entries into the computer that caused problems. How do we know from the radar that the airplane made those turns . Part of me says that the engines must have been running, we must have had electrical power to the transponder and the trance ponder was sending information back to the radar, so if thats the case and the engines were running and we had electrical power, why didnt we get a broadcast from the crew and it would also indicate that maybe we lost control, maybe we lost the vertical fin, if you dont have the vertical fin, the airplane doesnt point straight ahead any longer. Theres just so many questions that wont be answered until we have fiphysical evidence. If this plane did explode, john, what kind of evidence would investigators be looking for in the wreckage, assuming they find some wreckage in the mediterranean . Just like we did in the sinai, the metal doesnt lie, if they used the same m. O. And put the explosive in the tail of the airplane, the tail is the most vulnerable. We will see the blowout of the tail, that no, sirforced the pi this plane. Well see bits and pieces on the interior of the airline, the seats, and also if we recover bodies, the bodies will be examined looking for residue and other telltale signs of a blast . How optimistic are you that they are going to be able to recover some wreckage . The black box and the fligs enough information on them that we could be able to make a determination. I hope they have already started i hope they have already started to look for them. Because as we know, we only have 30 days on the pinger, and here we are, were already approaching the 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. Well take a quick break here, when we come back here live from france, well take a look at what happened today, what it means for politics, what it means for National Security implications, well take a look at that plus more reaction from here in paris right after this. Fact. Theres 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 filmcoated in the white box relief doesnt 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 . Well dig into that and what donald trump and Hillary Clinton said about todays plane crash, well talk about that right after this. Systems. It recognizes pedestrians and alerts you. Warns you about incoming crosstraffic. Cameras and radar detect dangers you dont. And it can even stop by itself. So in this crash test, one things missing a crash. The 2016 eclass. Lease the e350 for 499 a month at your local mercedesbenz dealer. Ugh. Heartburn. G ] sorry maam. No burning here. Try new alkaseltzer heartburn relief gummies. They work fast and dont taste chalky. Mmmm. Incredible. Looks tasty. You dont have heartburn. New alkaseltzer heartburn relief gummies. Enjoy the relief. When egyptair flight 804 went down, it went down amid heightened terror alert in this part of the world. Well 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 canting some terror to happen since the Brussels Airport attacks. Again, we dont know what happened, we have to reenforce that we really dont know if its a terrorist attack, but the french officers in the past two weeks were telling people, something might happen, be careful, were all careful, they have the least of targets in france and egyptair has had a lot of problems in the last year, there was the one that involved the plane october of last year. And there was also someone who tried to hijack an egypta egyptairplane in the last few months. Because egypt and france were the ones that were expecting a strike. It did not take too long for the two president ial front runners to weigh in on what happened just off the coast of egypt. I want to play for our viewers and our listeners at home, Donald Trumps response and Hillary Clintons response to all this, take a listen. That are provocative, that actually make the important task of building this coalition, bringing everybody to the table to defeat terrorism more difficult. Why . Because when he says bar all muslims from coming to the United States, that sends a signal to many muslim nations, many of whom we have to work with to defeat terrorism, some of them are already our strongestron strongest allies in this fight. Its a sign of disrespect. What just happened 12 hours ago that got blown out of the sky. If you dont think it was blown out of the sky, youre wrong, okay . Theres been no official word on whether the plane was in fact when out of the sky. But lets talk about those two responses, what can we glean from those two responses. The other thing that was cn in the clip that you played, was that how Hillary Clinton responded, to marshall with our allies and partners, to go about orchestrating a response to hold the people who orchestrated is attack to account. She highlighted the fact that we dont know what happened. On the other side, we had donald trump step out and make some interesting claims that he knew that it was a terror attack anyone who didnt realize that was an idiot. This was really unpresident ial. And the question is do you want a commander in chief whos going to jump to a conclusion like this before everything plays out. What you saw in secretary clintons response was someone who was acting like a security professional. All of this coming just a week or so after both of them, again, a function of being the presumptive nominees at this point, theyll start receiving their pentagon briefings, National Security briefings thats similar to what the president of the United States gets. Those here who are looking at the Islamic State are looking is the french sources, the french intelligence also are telling us that libya is a very sensitive country, the Islamic States, is now an infrastructure in libya, part of libya, are dominated by the Islamic State and they believe that if it was a terrorist attack, the symbol of the preseason was carefully chosen. Why . The plane was coming from first, you know that france has been hit by the Islamic State, and then egypt, its something that the Islamic State does not want, and libya has this war with egypt. And investigations at this moment and the french intelligence, it could have been the perfect target, if its confirmed that its a terrorist attack. And again i think we should continue to drive this point home, again, its very early in the investigation, we dont know whether this was something that was terrorist related, although a number of officials have indicated they do believe it is. If it does turn out to be terror, if it does turn out to be another isis attack, what then does that mean for us in the United States of america, with regards to policy . There are a couple of issues, simply from a homeland protection issue, its going to be very easy to figure out, if it turns out to be a bomb, where was the bomb loaded in was the bomb loaded in tunisia, which has sent more than 6,000 foreign fighters to syria, or was it loaded in paris . And if it was loaded in paris, we have to take a hard look at whats happened here, because if memory serves, i dont think we have had a bomb placed out of a European Capital since lockerbie, and that would be a significant break in security. Harden, thank you, laura a big thanks to you as well, its approaching 5 30 here in paris behind me, the sun starting to rise over the Charles De Gaulle information airport, as the sun rises here, the sun also rises above the Mediterranean Sea as well. When that happens, the search effort will continue. Theyre trying to find trying to find egyptair, flight 804. Lots more here on msnbc here after a quick break.

Was there some sort of mechanical malfunctioner or was it something more sinister, the idea that it could have been terrorism. Its renewing security efforts in america and abroad. Pete williams with a look at that. Reporter passenger lines were longer and slower in atlanta, but moving better notingly better in chicago. Passengers saying that the elipt especially when youre flying overseas, its really scary. Authorities in los angeles say they stepped up security as a precaution. Homeland security has done more to check flights bound from overskaes. But some Security Experts say more could be done to further protect air travel at home. One suggestion for dealing with potential insider threats, screening airport employees who have access to planes, checking their backgrounds before handing bags. Introduce random security measures for employees so they dont know whats going to happen day to day. Reporter the system now relies in part on screening by known and thrusted shippers. Tsa says its improving the ability to who have made developing such bombs a priority. U. S. Officials say tonight until the cause of the egyptair crash is known, it is impossible to say what measures will be updated here at home. Pete williams for us at Reagan National in northern virginia. Seth kaplan is a commercial aviation expert, he is also a managing partner of airline weekly, what kind of security procedures would have been performed on this particular plane in addition to the obvious . Yeah, i mean, it would have gotten a sweep in paris, but nothing necessarily all that extensive. You know, nothing that might have detected, you know, if there was a device bought aboard the plane, whether it was in tunisia or in cairo, and hidden somewhere, yeah, you know, thats not really going to be detected. What has changed, for example, since lockerbie, in that case you had a bomb that was by all appearances placed aboard in malta, changed planes in frankfurt and wasnt caught during screening. If you had a bag changing planes these days probably would be caught. But that would be unlikely to happen here because you would have bags connecting on to this flight, just the way the tickets would have been sold, its out and back from cairo in this case, and so, yeah, the best guest and thats really all it is at this point craig, is that it would be brought aboard somewhere, you know if it was somewhere else and not caught. You mentioned indonesia and thats important to this conversation, because that is where this plane had spent time in the 24 or 48 hours prior to the flight from here, Charles De Gaulle to cairo, and we know that that part of the world over the past few years has a hot bed for terrorism at airports in that part of the world, specifically. If there was some sort of breach here in Charles De Gaulle, what would that mean for International Airport security, what would that mean Going Forward . The impact, craig, would be huge, you know, again, if youre just sort of trying to say, well, whats the best guess here . The reason that it was put aboard somewhere else is somewhat incredible, but you can construct a case about why they would target egyptair, if you can penetrate security at de gaulle, there are some higher priority targets, so thats why at this early stage, your mind kind of goes that it might have been brought aboard somewhere else. But if they penetrated the security there at paris, you heard people talking about it, better screening of airport workers and things. But for all this talk about airport security, when you think about plots that have succeeded and failed, over the past decade and a half beginning with 9 11, almost always, it kind of has to do with intelligence, than it does with airport security, 9 11, all we do in response to 9 11 at the airports, that was primarily an intelligence failure. Those box cutters that got through, those were legal on that day. But it was more about people who were interested in learning how to fly planes but not land them. It was nothing that was caught at heathrow, it was infiltrating those cells. So its always a combination of, yes, tighter airport security, and on the other hand most recently brussels too a failure by all appearances of agencies not doing perhaps their best in sharing information. Seth kaplan, we will have to leave it there, sir, thank you so much for your time and your insight. Thank you, craig. When we come back here, well reset things, well get you caught up with the very latest on the investigation, well also take a look at the black box and why that socalled black box will be very important to this investigation here.
