Here tomorrow night. Ac 360 right now. We begin with breaking news. In a string of potential development in the crash of metrojet 9268 the latest from cairo. Today egyptian authorities said their on the scene work was done and the stream of information continued. So did the contradictions. Russian state media reporting that investigators found no signs of what they call explosive impact on the bodies recovered so far. And the american satellite that detected a heat flash when the plane went down. Rene marsh joins us right now. We know today the u. S. Embassy in cairo issued an advisory, warning all embassy employees not to visit the Sinai Peninsula right now pending the outcome of the investigation. The u. S. Embassy is calling this a precautionary move but no indication of a status change for the troops in sinai right now. There is new information about the heat flash detected by that satellite. We know that a midair flash happened right before this plane essentially crashed. U. S. Military sources are telling Barbara Starr that one of their satellites detected a heat flash while the plane was still in the air. This suggests a possible explosion caused by a bomb but it could be tied to a failed engine exploding or a structural or mechanical problem with the plane. The airline is quick to come out to say there was no mechanical failure and russian state media just today said there are no signs of explosive impact on the bodies of the victims. No essentially no blastrelated trauma. But we should point out that does not necessarily rule anything out. Just look at 1994. There was an Airline Flight philippine flight 434 with 273 people on board and a bomb on board that jetliner, one was killed and ten others injured and everyone else survived. We learned that security measures have not been tightened at the airport. Egyptian authorities saying they see no indication this was an act of terrorism. And an affiliate of isis claimed responsibility. What to make of it all . How much do we know about this isis affiliate in sinai . While this isis affiliate has struck targets around egypt they have been confined to the northern part of sinai. They rose out of the arab spring in 2011 but not until the 2013 overthrow of Mohammed Morsi when a wave of violence started. They have killed hundreds of police and civilians. They have antitank missiles that have hit tanks and a boat in the mediterranean. And they have shoulder fired surfacetoair missiles. And we have seen them take down a helicopter. They might have been able to bring down this plane with that missile . There are two theories of how they could do it. The first is a surfacetoair missile which seems unlikely and we can put that aside at this point. They can only reach an elevation of about 14,000 feet and this plane was at over 30,000 feet. The other possible scenario is putting a bomb on board and all the evidence points to that being a possibility, not the reason but a possibility at this point. And if that did happen, that raises serious questions about security at egypts airports. Egyptian and russian authorities have downplayed any link to terror saying it is mostlikely a mechanical issue. But we wont know what caused this plane to go down until the investigation is over and what we can learn from the black boxes. Ian lee, i appreciate it. I want to bring in david soucie. He is a former investigator and general mark hurtling. This isis affiliate claims to have bring down the plane. The name of the group is sinai. They have been emerging within the last two years or so in the Sinai Peninsula. They have been troublesome to the Egyptian Government and the israelis. Last july the Israeli Defense forces said this is the most Prevalent Group in the middle east. They certainly have some capability. We mentioned the attack on a boat within the sea nearby by a missile which is a russianmade missile and used it every two or three days, attacks on egyptian ground forces. They are a Relevant Group now. Many people in the multiforce Observer Group we have 700 americans there have been reporting on this group for about two years now. And the u. S. Officials are saying this heat flash detected by a u. S. Military satellite was detected midair. If this is a massive mechanical failure, what could have happened . Well, the only way the only example that we have in history is that when an aircraft came apart in flight and tore the fuel tank in half and that caused the fuel to burn and causing this eruption or flash. That could be what this is. That than a bomb on board. Y its a bomb on board would not have within too big to rupture the fuselage and cause this to happen. Most of the passengers have no explosive residue on them meaning it was torn apart from a mechanical failure or a small bomb inside. U. S. Officials are saying it is a catastrophic event in flight. You believe a bomb is a possibility . I do, anderson. And i harken back to pan am 03 over lockerbie. A bomb near the tail section of an aircraft, in this case all evidence would support that given the fact where the tail section was found in proximity to the rest of the wreckage. A bomb would not have to be a large device as a matter of fact. You wouldnt get this idea of explosive residue or burn marks on passengers as a result of an explosion. All you have to do is knock the tail off that aircraft. I have never flown out of that airport. In terms of security, how good is it . A long time ago it was not very good. I dont have recent experience there. But its a tourist town. A lot of europeans go there, russians, western europeans travel there because of the great resort area it is. Thats part of the problem, the Egyptian Government dont want people to think this is an unsafe area. Its a big diving spot. A great diving spot. It is not the best security in the world. And certainly in the middle east. But i cant vouch for it in the last two years or so. But i think they have had a lot of trouble and attacks by these groups. You would think the security would be increased. They have had gate jumpers there and attacks there. This is going to be a new focal point. And according to the flight data tracker, the plane slowed down suddenly and plunged 300 miles an hour. And the direction was wobbling from side to side. What does that tell you . That it was a break up in flight. There is no directional control of the aircraft. There is no control going left and right. It would be consistent with an inflight break up. Does it surprise you that the air Traffic Control did not have any distress calls. If you harken back to previous events like this, like twa 800 which was a fuel tank explosion, there was no chance for the crew to get a radio call off. And interfax is reporting that based on the flight data recorder there were uncharacteristic sounds heard before the moment the flight disappeared. Can you read into that . Going back to twa 800 there was a brief noise which they analyzed in excruciating detail which they realized had to do with the explosion in that case. And in mh17, investigators there spent time using the acoustic information to isolate how that missile struck and where it struck. So that kind of information is very useful and those strange noises will be poured over with the right expertise and can tell a lot. Miles, and david soucie, thank you. More parallels between this and twa 800 and the lessons that apply 20 years later. Later donald trump unloads on the competition in ways you have to see to believe. And he takes a shot at us. Keeping him honest tonight. Bas. Why cant we just get in the running car . Are you crazy . Lets hide behind the chainsaws. Smart. Yeah. Ok. If youre in a horror movie, you make poor decisions. Its what you do. This was a good idea. Shhhh. Be quiet. Im being quiet. Youre breathing on me if you want to save fifteen percent or more on car insurance, you switch to geico. Its what you do. Head for the cemetery to prove to you that aleve is the better choice this is claira. For her shes agreed to give it up. Thats today . Well be with her all day to see how it goes. After the deliveries, i was ok. Now the ciabatta is done and the pain is starting again. More pills . Seriously . Seriously. All these stops to take more pills can be a pain. Can i get my aleve back . For my pain, i want my aleve. Get all day minor arthritis pain relief with an easy open cap. Can a a subconscious. Mind . A knack for predicting the future. Reflexes faster than the speed of thought. Can a business have a spirit . Can a business have a soul . Can a business be. Alive . Well, right now you can get 15 gigs for the price of 10. Thats 5 extra gigs for the same price. So five more gigs for the same price . Yea, allow me to demonstrate. You like that pretzel . Yea. 50 more data for the same price. I like this metaphor. Oh, its even better with funnel cakes. But very sticky. Get 15 gigs for the price of 10. And now get 300 credit for every line you switch. Now at at t if you have moderate to severe. Isnt it time to let the. Real you shine. Through . Introducing otezla, apremilast. Otezla is not an injection, or a cream. Its a pill that treats plaque psoriasis differently.

Ask your doctor about otezla today. Otezla. Show more of you. The breaking news, a warning to u. S. Embassy employees in egypt stay out of the sinai. We have seen a terror Group Claim Responsibility and thread authorities downplaying the possibility. There are hints of a mechanical failure and more questions than answers at this early stage. There are echoes of another disaster that cell vent two decades later. Randy kaye has that story. July, 1996, twa flight 800 takes off from jfk airport. 12 minutes into the flight the plane explodes. We saw an ploegs up ahead of us somewhere about 16,000 feet or Something Like that. It just went down. You saw the two wings come off. And the fuel coming out of the wings. It was on fire. This pilot was on a different plane and he thought it was a bomb or inflight explosion. Whatever it was killed off 230 on board. Some said it was fireworks and some said a missile. The fbi and ntsb looked at every possibility. The black boxes were in Good Condition but offered little since both stopped recording. I spent hours and days looking at every piece of metal looking for the telltale signs of a missile and there were none. The fbi spared no expense to show it was a bomb and they couldnt prove it was a bomb. In the end, investigators determined that 800s Center Fuel Tank exploded, causing the plane to break apart. The government said there was no proof of a criminal act. He expects the same type of conspiracy theories will result from the crash of metrojets 9268. There is already talk of a missile and a bomb. A heat flash detected at the time of the crash suggests a catastrophic inflight event. That heat flash is similar to the red flash that people witnessed when twa crashed and that determined to be the plane already on fire at 8400 feet in the night sky. Whatever brought the russian jet down caused the tail to break apart from the airplane. When that happened will be key to the investigation. So will the burn marks in the desert. The airplane hit the ground and didnt scatter, possibly preserving important clues. Randy kaye, cnn, new york. And john joins us now. He is the first ever certified airframe and power plant mechanic to be on the National Transportation safety board. Few know more about how planes are put together and can come apart. How likely is it that this was a catastrophic mechanical failure rather than something more few neighb nefarious. It is unlikely it is a fuel tank explosion because of the effort to make sure that doesnt happen again. There was a tremendous amount of work and resources that went into making sure that we wont revisit that event again. There are other things that can happen to an airplane to cause them to come apart, some of them pretty easy. But the scenario that we have today doesnt fit any of the easy theories. Something happened up there. It could have been a computer failure or inappropriate actions on the part of the pilots that stalled the airplane or a device on the airplane. Its not likely an engine that failed catastrophically and broke apart. It was something a little bit different than what we would normally see. There is a report that the victims bodies show no signs of an explosive impact. Does that rule out a bomb . No, it doesnt rule out a bomb. They have not looked at every body yet. Im sure they will. If there was a small device in the cargo compartment that wasnt enough to blast the airplane apart but to fracture the fuselage and come apart based on the air loads which is what happened with twa, it doesnt have to be a big boom but just enough to start the failure of the structure and the airplane will self destruct. One part destructs and then it sort of a Ripple Effect . Remember, the airplane in flight is under a tremendous amount of loads and that is meant to be transferred to strong parts of the airplane. So once you disrupt that flow of primary structure moving the stresses into an area you want it to go into, the stresses will go into the areas of the fuselage that cant handle the stress and it will self destruct. The same plane in 2001 suffered damage to the tail after it struck the runway but it was repaired. Could have contributed to this crash . Actually, the length of time can add to it. If the repair was made improper then the stress fractures could cause it to fail. But you know, based upon the pictures i have seen and thats not the best pictures and the best way to look at it, it doesnt appear that that pressure bulkhead failed. But if they had enough of a tail strike we may have weakened the structure somewhere else like the picture on the screen right here where the inspection is. If the structure was weakened there and had cracks in that area and they didnt materialize until later that could have been an effect. So you know, investigations are an exercise in time, patience, and following procedures. We have in the worldwide Aviation Community a set of procedures that have yielded good results for years and years and years. Youre going to see 20 to 25 teams pouring over this airplane out in the desert, each doing their speciality, their thing. And separate from what the recorders and what everybody else says these folks are going to build a book of facts and those are going to lead to a n conclusion. Thanks for being with us. And donald trump saying that we threw him softballs at the debate. Keeping him honest next. Well, because their technology is far superior. Or because they have someone on the inside. Is that right, gil . Sir, i would never. Hes with them hes wearing a wire. Take off his shirt take off his shirt oh ah alright, im putting you in charge of the holiday party. vo get rid of cable and upgrade to directv. Call 1800directv. Life. Is unpredictable. Life is deaths. And births. Sickness and health. Love and heartbreak. And covered california is there for it all. Not just to help keep you well. But to make sure the cost of being unwell doesnt ruin this whole life thing. Because its more than just health care. Its life care. Election day 2015, exactly a year until election day 2016 and we are getting a new picture of what it would look like if we were counting the vote right now. There is a poll which shows that a head to head matchup between Hillary Clinton and ben carson would be a tie if the election were held today which it was not. We have a long way to go. It got us thinking of the state of the last president ial race one year out. Obama was unchallenged. But on the republican side, herman cain was leading. Mitt romney was second. This time around it was carson, trump, rubio, cruz and jeb bush. Donald trump was promoting his new book and trashing opponents and making claims about the cnn debate. This is what he said about my moderating the day after. He tweeted, Anderson Cooper did an excellent job of hosting the debate last night. Tough, firm, but fair. Hillary clinton was given all softballs not asked one tough question. Keeping him honest, he is right. We did not ask one tough question but a lot more than that. Here are a few examples. Were against samesex marriage and now for it. You supported his trade deal dozens of times and called it the Gold Standard and now you are against it. You are going to be testifying before congress about your emails. You havent been able to put this issue behind you. You joked about it and called it a mistake. What does it that say about your ability to handle crises as president. How can you represent the views of middle class. Did you underestimate the russians and as president what would your response to put been in syria. Who would you do for africanamericans in the cu country . As for his rivals, this is what donald trump said about them. Jeb, he lacks the quality that you need. I think that marco is highly overrated. Ben carson does not have that energy. Marco doesnt show up to the United States senate. What jeb bush was saying at the last debate, he didnt say it well. Bernie sanders lost his whole campaign. Marco rubios personal finances are discredited. All you have to do is look at his credit card. He is a disaster with his credit cards. He certainly lives above his means. My jeb impression . I dont want to do that. I dont like showing a person sleeping at a podium. Joining me is jeffrey lord and van jones. Jeffrey, criticizing the debate moderators, whether me or someone else, going after fellow candidates, is the reality just that . That those sorts of comments are red meat for the base own they serve him well or is there concern in the campaign because he is trailing in two polls . Y i think its the first. I believe that he is giving voice to the base of the Republican Party believes to its core
