Were were continuing our coverage right now of egyptair flight 804 which we are now being told has crashed somewhere in the mediterranean. Little earlier on we spoke with matt olson who is counterterrorism expert. Of course, many people are saying that might be one of the possible causes. Still an early stage in this investigation. That does not mean it is terrorism, but just a lot of things pointing to that right now and we got matts take on why. Weve seen in mishaps in the past, if you remember the mishap in Sharm El Sheikh egypt, the russian airplane that went down. When an airplane just disappears at altitude, the cruise altitude, its very unusual. Its usually something that will bring it thats catastrophic that will bring it down, perhaps a bomb or a hijacking or somebody takes control of the airplane, but an airplane, an airliner at cruise altitude is a very safe place to be and theres no reason in the world that an airplane should just disappear other than something nefarious or catastrophic happened. In terms of looking at other possibilities, the weather radar were looking at looks fairly clear. Do you know anything about that flight path that might raise any concerns . Well, we always were always concerned when an airline from middle east is involved. Weve seen air terrorism in egypt in the past. Weve seen a number of instances where we know that terrorists or people who would do harm for causes that are related to the middle east have been related, but anything going into the middle east where you have egypt very tense domestic situation, its just going to raise all sorts of flags. And of course the first thought will be is terrorism involved. Absolutely. I imagine this will be a multiagency, multicountry investigation that is taking place right now. Give us a sense of what mobilizes at this early hour. Well, right now it will be the recovery thats going to take priority. The egyptians, because it appears the aircraft has come down in egyptian air space even though its over the mediterranean will take the lead on that since its Something Like a disaster at sea youll have all sorts of nations joining. And so any nation that has ships or boats or rescue capabilities along the mediterranean will join in the search, but because its an egyptian airplane, because it occurred in egyptian air space, egyptians will have the lead in the investigation. Were talking about quite a few hours since the last contact with this plane, what does that do in terms on theories of what happened here . It just continues to deepen the mystery. Again, an airplane should not disappear at 37,000 feet. Because we have so much good data, this airplane will not go missing in the same way that the malaysian 370 flight that we lost off the indian ocean, still havent found years later, were going to find this airplane. Were going to find the wreckage, the mediterranean is not too deep in this part of the eastern med. So well find the airplane. Well find the black boxes and so i think well have a pretty good chance of determining what went wrong. We havent yet heard any reports of distress calls coming from the plane. Does that help determine whether mechanical failure may or may not have played a part . Mechanical will be one thing to look at, but again the fact that it just disappears is going to suggest something more ne fair warehouse, perhaps something explosive that would have made the airplane come apart instantaneously and not given the crew a chance to render a may day call of any kind. I should point out since talking to matt, we did learn that the plane equipment did send out a distress signal, but still no word of a distress call from the pilots. Whatever went wrong, the pilots did not have a chance to radio in and report it. The distress automatically happens once the plane hit the mediterranean, the equipment sent up a signal to the gps that is flying above to give it a location. So right now you have a lot of people who are searching that area near karpothos in greece for this plane. Analysts trying to get more information from it. A big search again for missing egyptair flight 804 with 66 passengers on board and we will have more on that continuing coverage coming up and after the break some News Headlines for you.

It vanished over the mediterranean with 66 people on board. And we are now going to some footage we have of family members, live video of family members standing by, waiting for answers. So many questions still left to know what happened to their family members and particularly in cairo and in paris. Paris where the plane left. Cairo where it was destined to land. Authorities there are setting up Information Centers for these family members to try to give them news as they get it. We know there were 15 french citizens on board, 30 egyptians and a mix of other passengers. A total of 56 passengers on board plus 10 crew members. Those are images. You can see the grief on that one particular womans face there as we believe paris Charles De Gaulle. We want to show you a live picture right now. This is of the cairo airport where that plane was expected to arrive around 4 00 local time this morning. Just i would say about 175 miles or so from that location where its believed right now by aviation officials that the plane went down. Theres a massive search effort that is taking place at this hour for that plane. We show you here the map and you can see where that search is centered near the island, greek island of karpathos. They last received communication from the pilots at around 37,000 feet, cruising altitude which is raising lots of questions over what went wrong here. Thats generally a very easy time for flying, not many things go wrong when the plane is at that stage. Also, a distress signal was sent from the plane we believe on impact when the plane crashed. However, we want to stress the difference here. That was a distress signal from the emergency equipment on board. That was not a distress call from the pilot. So the deduction there is that whatever did go wrong the pilots did not have a chance to radio in and report whatever that problem was. We also have weather radar over the sea that showed clear skies at the time and the airline has been saying they got no other reports of distress from the plane and nothing of suspicion in the baggage. The plane was an airbus a321. Its fairly reliable and popular plane. Made in france back in 2003. So farce planes go, it was relatively young plane with no known problems prior. And it had 66 people on board, 56 of them were passengers, 3 young infants among those on board. There were just a little suspicious from any folks, there were three air marshals or the equivalent of three air marshals on board this plane and some seven crew members as well. Some saying three Security Officers for a plane of that size is a little high though not a huge indication necessarily of anything here. Just a lot of questions right now, both egypt, greece and now breaking news this morning on world news now. The search for a missing plane. The egyptair flight was headed from paris to cairo before disappearing from the radar. 66 people were on board. Its still unclear as to what caused the plane to just vanish. We have full coverage of this developing story on this thursday, may 19th. Announcer from abc news, this is world news now. Good morning, everybody. Im kendis gibson. And im diane macedo. Lets start with the breaking news report, the disappearance of an egyptair jet over the Eastern Mediterranean sea. The plane designated egyptair flight 804 left Charles De Gaulle airport late last night. It was headed for cairo, egypt but never arrived. Then we got the troubling tweet from egyptair, airbus was flying at 37,000 feet when it disappeared from radar roughly about 3 1 2 hours into its flight. It vanished around the time it had entered egyptian air space. Egyptair says 66 people were on board including 56 passengers and ten crew members including three security guards. And joining us now with more on this we go to abcs molly hunter. Molly, i know youre en route to go to this destination. Tell us what you know so far. Whats the latest on this investigation . Reporter absolutely, diane. We actually just learned moments ago from egyptair, they just tweeted out that the plane actually sent a distress signal. This is the first weve heard of that, that was received by the armed services. All of the information we have been getting has been coming from that twitter account since that tweet that kendis mentioned. But we dont know very much. We know that the plane lost contact about 3 1 2 hours into its journey. We know it lost contact about ten miles inside egyptair space over the mediterranean. Early reports now that the plane may have got we dont have enough information yet. We do know this was an experienced pilot. He had more than 6,000 flying hours. And you mentioned those passengers. 56 passengers, ten crew including three air marshals. At this point, diane, we dont think any americans were on board according to manifest we have. Molly, we should tell you the breaking news were just learning right now at this hour that egyptian aviation officials, according to the a. P. Say the egyptair flight 804 has crashed. Not exactly clear where but they are confirming the plane has crashed. Reporter interesting. Well certainly be hustling to find out more information on that. Again, we covered that plane crash last fall in egypt which was a russian aircraft in Sharm El Sheikh, a Tourist Destination on the red sea. Again, aviation history in the last year or so in egypt not great. Well get back to you as soon as we know more. Thanks for that. Molly, apparently that distress call from the planes emergency equipment. Having covered these kind of cases before, what can you deduce from that . Reporter it will depend on which part of the plane and which whether that distress signal came from the transponder or from the pilot directly. As soon as we find out more information from that, well hopefully be able to pinpoint exactly how that distress signal came out and where that distress signal came out and hopefully pinpoint the planes last known location. But we dont have that information right now, diane. And molly, quickly though, i mean, you were there in Sharm El Sheikh or in the Sinai Peninsula after that incident last fall. Give us a sense of what sort of changes egyptian officials have made as far as security goes on board these planes and at the airports. Reporter absolutely. Its certainly telling there were three air marshals on board. I can tell you thats certainly more than normal egyptair flights have, at least in the local calls in the region. When we were at Sharm El Sheikh, we spent a lot of time talking to security officials. Ive gone through security both at the cairo International Airport and Sharm El Sheikh international. Its been incredibly light. Historically, really, really easy to go in and out of those airports. I recently flew out of cairo about two weeks ago and the security has been beefed up since last fall. But ill tell you, its nothing compared to flying out of Charles De Gaulle, flying out of heathrow in london or jfk in new york. Certainly after that crash in the fall, changes were made especially at Sharm El Sheikh. A whole review of that Security Apparatus at that airport was done, at all egypt airports, as well. Ill definitely report back when i arrive in cairo later today to see if that security has even been beefed up further. Molly hunter en route to the airport for us enroute to cairo there. Molly, thank you so much. Earlier, we spoke with colonel Steve Ganyard who is a security expert at abc news. I should caveat that we spoke with him before the breaking news that we got from egyptian aviation officials that this plane has crashed. Right and that they have received a distress call. Theres so Little Information on this right now. Where do you start in an investigation like this . Well, we have radar data, which is actually better than radar data. Its the Global Positioning system data transmitted from the aircraft. Even though the aircraft was lost well out to sea, theres going to be good data on the altitude, the air speed and what the aircraft was doing in its final moments. I think well have a pretty good idea whether the plane did just disappear which may suggest a bomb or did it go into some sort of steep descent. We obviously dont have any radar transmissions. Lots of questions at this point but i thi
