Greece lost it from radar. Just moments ago, egypts government in charge of the investigation says terrorism is more likely to blame than any technical failure. This is what we know right now. The paris to cairo flight had 66 people on board. Air Traffic Controllers in greece say the egyptair pilots did not respond to the calls during the last 90 seconds of the flight. It vanished from the radar, 173 miles off of the egypts coast. The problems emerged at 37,000 feet. Aviation experts say this is the safest part of the flight, because it is at cruising altitude and under less stress. Were bringing of all of the late ets developments. Lets begin with Nic Robertson in london. The latest information we have coming in from greek authorities is that some debris, two pieces of debris, have been spotted, 50 miles southeast of the site where the aircraft disappeared off the radar. It is not concluded whether the two pieces of debris are related to the aircraft, but it is in the area of the search. This is something that is coming from greek authorities. This needs to be further confirmed and clarified and run down, but this is the first indication weve had of any debris spotted in the search. We know the greek aircraft, greek naval vessels, Egyptian Navy vessels are jointly involved in scouring the Mediterranean Sea for debris. Its been about 13 hours since the aircraft went down. So that operation has been underway for a long period of time already. The indications concerning authorities that while the greek authorities aviation authorities were trying to talk to the pilots of the aircraft after as they were moving between greek and egyptian airspace, the pilots were not responsive to greek authorities. They had been responsive a few minutes earlier, at the same time, the aircraft was noticed going into that very troubling maneuver. 90 degrees sharp turn to the left, 360 degree sharp turn to the right, but at the same time, losing thousands of feet and altitude and then disappearing from the radar, carol. All right, Nic Robertson, reporting live from london. I want to bring you to cairos international airport. Thats why ian lee is. Family desperate for any information on the flight. What are officials telling them . Reporter well, officials when were talking to family members, officials are not giving them much information, about the same as were receiving. One thing that is different from what we heard from the minister of Civil Aviation, still saying that this isnt a crash, that the plane has disappeared, but when theyre talking to the family members, they have a different story, saying that the plane actually did hit the water in the mediterranean, and thats what were hearing from family members. Although, of course, theyre quite distraught here. They want to know what happened. They want to know what caused this plane to go down. They want the same answers that we want, and there is some frustration with them, with not receiving these answers fast enough. But of course, this is an investigation just in the preliminary stages, and we did hear from the minister of Civil Aviation sharrif fahit, than being mechanical. That is something that they are going to be looking into now. It is a bit of a shift in the focus of the investigation where it is going to where it is going to go from here. What happened at the airport in Charles De Gaulle, all a lot more questions now. But also, the investigation, the search, still continuing. All right, ian lee reporting live from cairo. We want to talk to the experts. Cnn and safety inspector, david soucie, im also joined by mary schiavo. David, when Authorities Say it is more likely terror than a technical problem, why do they think that . Well, the fact that there was no response back from the requests for information from the airline itself, and the fact that the flight profile doesnt match anything that would be done by intent, i think that theyre right on with this, and if you know me from before, all say im the last person to go towards terror or intent, but in this case, the profile looks theyre correct on that. So mary, we know the plane took a sharp turn to the right and then a sharp turn to the left. Air Traffic Controllers lost contact with the pilot, just as they passed into egyptian airspace. What does that tell you . Well, unfortunately, going back to other crashes and ive worked in the past, when it makes a 360 degree turn as it is losing altitude, what that usually signifies is the plane is tumbling or it has lost its lift, meaning it has an aerodynamic fall, and it flutters like a leaf. So a 360 degree turn, with a fall to 22,000 feet and then to 10,000, suggests that i hate saying this, but falling from the sky, it is out of control. So david, what is going on in the cockpit at that time . There is a couple of things that can go on. In the power is on, it is continued power, but perhaps the aircraft is over exceeding the claim rate and starts to stall. It is what is called a flat spin. Trying to recover from that, the pilots will try to identify the problem, maneuver theyve designed specifically for this aircraft when it gets into a spin, and they go full right and full left rutter, and it rocks its way out of that fall, out of that flat fall, as mary said, like a leaf. Once it gets momentum going in one direction, the pilot turns the aircraft completely to that direction and at that point, the aircraft is trying to get some air over the top of the wings, create lift and then at that point, can glide to a safe landing. So this profile does match some of that, not exactly, so im not certain about it. But if this waivering is true, if it happened, it would fit that profile. The thing thats concerning about that is why then did the adsb go offline prior to this event. If it was just a stall, caused by some other movement, it would have had to be preceded by some kind of catastrophic failure to cause the adsb signals to go offline and continue to fly. So david, explain to us what that is. Okay, what that is the directional signals that come from the airplane that tell the air Traffic Controllers and tell the radar where the airplane is and what it is doing. So those signals are continually sent. Thats the only real data that we get from the aircraft that tells us location, speed and altitude, all in the same area. So at that point, when it turns off, redundancy too, they would would have to have gone off someticat str catastrophic failure. So mary, if it was an act of terror, a number of scenarios, right. It could have been a bomb on board, somebody could have broken into the cockpit. The pilot could have been in on it. We just dont know, correct . Well, we just dont know, but we have already a lot of clues. For example, the rate at which the aircraft fell. If they were fighting over controls, 17 years ago, which was the pilot suicide, the pilot had pushed the nose down and the plane was making a rapid decent, but the plane was still flying. Here, we know at the rate of fall, from 37,000 down to 10,000, over 22 in between a readi reading, thats a fall. Thats not a controlled flying down. We know whatever happened, happened very dramatically that caused the plane to fall from the sky. I think a lot of people are going to terrorism, because of the events, i mean, you cant help but notice the events of late. Particularly, the reports that Charles De Gaulle airport, they removed 57 employee security clearances just last november and december, because they had ties to terror groups. And other airports in europe. So i think thats probably the kinds of clues theyre looking at and concludes it was probably an explosion that knocked the plane from the sky. Okay. And im just getting word david and mary from egyptian officials that there were no known Security Issues with passengers on board the plane. They dont say anything about the pilot or the copilot or the crew. Of course, theyre still investigating, david. But i would think there is a large circle of people that theyre looking into. There certainly is. It doesnt surprise me the people on board didnt have that, because as mary said, they just under their security at Charles De Gaulle airport back in november. They rescreened 87,000 employees, and now theyve also improved their screening where the employees come to work, theyre screened as well on a daily basis. So that increased the security at Charles De Gaulle airport, so if there was a Security Breach at the airport, i would be surprised. But as we know about terrorism, they continually improve their ability to penetrate these safety measures, so whatever did happen, if it was a Security Breach, it was something new to us that well have to adapt to moving forward. Of course, mary, whenever they find debris, that will tell them a lot. Im just wondering, they know where the plane went down. It is in the Mediterranean Sea. It is not like the indian ocean. Why is it taking so long . Well, because it takes a long time for some of the debris to surface. There are many, many things that throat, the seats, parts of the wing, tires, luggage throat floats exacttremely well, it ta a while for it to come to the surface. We can assume here it was probably pretty much a straight down, given the fall from 37,000 to 10,000 feet. It was probably a straight fall. But then again, i just want to go back to one of the other points. On a device, you know, as weve seen in terrorist attacks in the past, devices take many different forms, some can be set off by someone on the plane, but others can be set off been a device, meaning when the plane gets to a certain altitude, it goes off. Well, here that wouldnt be it, because it was at 37,000 feet for some time. You would be looking at some sort of a timing device. That could have been put on a plane at any point, you know, basically at a 24 hour point. So there are many options in what david said, and that the sad truth is that the terrorists are always gaming the system, and seem to be sadly one step ahead. Okay, you guys, stick around. Stay right there, because were just getting word from the white house on this apparent crash. A the reporter monitoring the developments in the incident. I have this statement, who says the assistant to the president for Homeland Security and counterterrorism, lisa monaco, has briefed the president on the incident, egyptair flight 804. President has asked to be updated throughout the day, as the situation warrants, and has directed Administration Officials to reach out to their International Counterparts to offer support and assistance. So that is what we have right now coming out of the white house. Theyre going to be watching this closely as you probably know, carol, we know the u. S. Is already standing by, ready to help, the combined task force is making preparations to help if they are called on. This is according to a u. S. Military official with direct knowledge of the latest information. So thats what we have right now, coming out of the white house. Of course, the big question here is whether this was terrorism related, and we heard from egypt Civil Aviation minister saying it looks more likely to be terrorism than a technical issue. Well be watching from here. Already, athena, thank you so much. I want to go back to the panel now. How they would investigate, if it was a terror attack, who might be responsible, david, this plane also stopped at four other airports before it took off from Charles De Gaulle airport. It stopped at these four airports in the past 24 hours, in eritrea, cairo, back to paris. How does that complicate things in. It complicates it in the security working backwards, if it were a terror attack, which trust me, thats how they are viewing it, and they are taking this very seriously and the time is of the essence. Theyre investigating all of the airports, and anyone who has touched that aircraft has far as as an employee, gaubaggage hand, whoever touched in the last 24 hours will be looked at. The layover is not just given a preflight by a pilot, it is looked at by specialized personnel and look at every aircraft during the rotation, shift change. At that point, they would have identified things. However, if you recall, not too long ago, sharma el sheikh, a pop can exploded. As good as we can be with security and searching, the challenge will be who touched the aircraft within the last 24 hour period. So mary, how does such an what does it look like at International Airports involved in this . Well, first and foremost, it involves a degree of Cooperation AmongLaw Enforcement authorities in all of the countries and interpol. What they literally have to do and it is good theyre treating it as terrorism, criminal event, because that means all of the assets are put into play. If you weighed it all in a criminal investigation, then you could possibly lose much, much of the evidence, and people can get away. I mean, im remembering back to the september 11th, 2001 investigation, some people who had screener jobs at the airport, they left and were never found. We didnt know who their real names were. It is important to do that neatly there, approaching each of the airports right now, grabbing the records, security tapes of who came to work and who was carrying what, who was working that day, seeing if everything had the security clearances, and most important, seeing what parts of the airport had employees with full security clearances. For example, in the United States, many of the airport workers dont have full security clearance and do not report to work through security. So theyre seeing possible threat vectors, how can you get threats onto the plane. Who are the people at the airports. So im encouraged theyre treating it as a crime, as terrorism, because that means we have a lot more assets in the investigation. Mary, david, thank you so much for your insight.

All right, im just getting breaking details about this airliner that crashed into the Mediterranean Sea. Egyptian officials, c 130 spotted two floating objects in the sea, and they say it is offer the coast of crete. We dont flow if that is connected to the plane, but officials suspect it is. Here is what we do know. 66 people, including three children are feared dead after that crash. That egyptair flight 804 went missing over the Mediterranean Sea. Last location inside egyptian airspace. Final movement as a swerve and plunge, and loved ones have gathered in cairo and paris, waiting to learn whatever they can about what may have happened. Right now, in the Mediterranean Sea, a desperate search underway. This marine traffic map, it shows vessels rushing to where the plane is believed to have gone down. Thats not the right map. I can assure, ships are in the area, and planes flying overhead. Egyptian Officials Say theyve spotted two large objects. What they believe are pieces of debris, but again, we are not certain that that is part of this plane that went down. Joining me now on the phone, linda laperpoolo, what can you tell us about the search . Well, the greeks are working very closely with egyptian authorities. Military planes have been deployed, helicopters operating in the area. And the latest we have from the Greek Defense ministry is that an egyptian c 130 have spotted two floating objects about 210 miles nautical miles from crete. We have to be very careful with this information. It is just coming in. The greek teams, greek air Traffic Controllers were the last to speak to the pilots only minutes before the plane exited greek airspace. We know that not long before that, everything seemed to be working fine. The pilot was actually apparently in a pleasant mood, evening thanked them in greek. And not long after that, the authorities at greek air Traffic Controllers, they lost control, lost the plane off the radars. The plane, according to the Greek Defense ministry, seems to have descended suddenly from 37,000 feet, it fell to 15,000 feet, then to 10,000 feet, just after crossing into egyptians airspace. Thats where the greek authorities lost really, this is where we are with this. This is as much as we know up to now, in terms of what we have confirmed. So these operations of course will continue. It is still early in the day. There is still plenty of daylight in greece. Thats good. Operations have been going on for several hours now. And the floating objects are the first possible items that we can link to the missing aircraft. And linda, how many vessels are out there searching . Can you tell . By now, their vessels from a number of countries operating in the area. Of course, the greeks and egyptians were the first ones there. And International Assistance has been requested. Greece has also asked a number of countries for satellite assistance. So basically, asking other countries what they saw, what they have, and how they can contribute to this operation thats now underway. All right, linda, reporting live for us. We thank you so much. I want to, i dont know
