Tragedy of 9 11 have been seated in the minds of many people. And this is not the time to relax, because we know there are terrorist groups that are still determined to carry out attacks, including against especially against aircraft. Has there been chatter that would indicate any kind of terror link in this mystery . I think theres a lot of speculation right now. Some claims responsibility have not been confirmed or corroborated at all. We are looking at it very carefully. We, cia, are working with fbi and tsa and others, our malaysian counterparts doing everything they can to try to put together the pieces here. But clearly this is still a mystery, which is very disturbing. And until we actually can find out sort of where that aircraft is, we might have an opportunity to do some other forensic analysis that will lead us in the right direction. At this point, youre not ruling out that it could be no. Some sort of terror not at all. Not ruling out. He says not at all. The head of interpol, the International Police agency, is, though, downplaying, seemingly downplaying, the possible link to terrorism. Ron noble saying indications increasingly point to some other explanation. More on this coming up. Malaysian authorities have identified two passengers traveling on stolen passports. And they say its unlikely they were part of a terrorist group. The two passengers traveling with the stolen passports were young men from iran. Authorities say they entered malaysia using valid iranian passports, but they used stolen austrian and italian passports to board the plane. Our Senior International correspondent, nic robertson, is joining us from london, investigating whats going on. Police say there is no evidence the two young men were part of any terrorist group. What do Authorities Say they know about these two individuals . Reporter well, they believe they were young men. One of them, the one en route to frankfurt, was going to meet his mother there. Indeed they say it was his mother who raised the alarm when he didnt get off that flight. It seems he was trying to illegally emigrate to germany, at least. Coming initially, as you said, from iran, using his own passport, along with the other young iranian, getting to kuala lumpur a week before flight mh370. What we are hearing, though, from interpol, from the secretary general, ron noble, is specific to these two men. But as far as they were concerned, where there was so much focus on the question of whether or not they were on board with stolen passports to commit terrorism, he seems pretty clear on that. This is what he said. The more information we get, the more were inclined to conclude that it was not a terrorist incident. And if you read what the head of police from malaysia said recently about the 19yearold whose photograph is here, wanting to travel to frankfurt, germany, in order to be with his mother as part of a human smuggling issue and not a terrorist issue. Reporter so that rules out, it appears, those two young iranians. But there are more than 200 other people on that flight. And what we understand from the Malaysian Police is the investigation is looking at sabotage hijacking. The possibility of psychological breakdown of someone on board or personal issues between crew or passengers on board that aircraft. The fact theyre not talking about mechanical failure, talking about the potential of hijacking and sabotage, pretty much hijacking and sabotage fall you said the auspices of terrorism, certainly in many circumstances, wolf. So you can see that the malaysians too, while ruling out these two individuals, traveling on the stolen passports, theres a lot of room left open for the potential there could be somebody else on there, wolf. And what do you make of what we just heard from john brennan, cia director . He seems to be going out of his way, first of all, talking about the threat from terrorists against aircraft, u. S. Aircraft, other aircraft. But then he says hes not ruling out terrorism, not at all. Those are pretty pointed words hes saying. Absolutely. Look, we know al qaeda likes to target aircraft. They have had various plots, 9 11, the bojinka plot, liquid explosives plot coming out of europe, as well. And al qaeda has even been on the record of saying that the pilot should administer a drug to the co pilot so he can take control of the aircraft. What has investigators so focus and had so concerned is now this period of time that it appears the aircraft was operating with a transponder off. How did it come off . How did the plane fly so many hundreds of miles back the route that it had come on at 90 degrees, cross over malaysia again. How did that happen . The aircraft was flying. The transponder was off. There were two people in that cockpit, at least. Were there other people . Was it hijacking in that way or had the air crew taken control . Irresponsibly . Again, this is all speculation. But these are all the loose ends out there. And its caused by this period of time that the plane was flying with a transponder off, and extended and unexpected period of time, wolf. Nic robertson with the latest from london. Nic, thanks very much. So if the terror angle seems to be played down, at least by some, what does that leave others for explanations . Lets bring in congressman adam schiff, democrat from california, Senior Member of the house intelligence committee. Congressman, thanks very much for joining us. You bet. All right. So what do you make of what john brennan, cia director, is saying when he says not at all. He emphasized those words, not ruling out terrorism. What are you hearing . Well, i think hes exactly right at this point. We really cant rule anything out. We do know a lot more about these two passengers, but we probably know more now about those two passengers than we do with the other more than 200 on board. So were scouring the manifest, seeing if we can make any connections with any other passengers on board. Were looking for any kind of chatter, was there any evidence that we had before this of an airline plot around this time or in this location. So far, i think its fair to say that nothing has leapt out at us. It could be, you know, a plot that was hatched in Southeast Asia that didnt involve someone on the aircraft, but someone who put something on the aircraft. So, you know, we cant rule anything out. I think thats certainly fair to say. You just dont have a plane of this size go completely missing and be able to rule out any possibility. Because you remember, all of us remember, before the sochi winter olympic games, there was a threat alert that was issued by the u. S. About toothpaste bombs getting on plaenls. There seemed to be some targeting of aircraft. Have you heard anything in all of your briefings linking what happened with the Malaysia Airlines plane and that earlier threat that had been so widely disseminated . Wolf, i havent. I really havent seen any indication of linkage between the disappearance of this plane and the threats we were so concerned about around the olympics. And thats exactly what were looking for, connections to those threats. But also did we hear any kind of chatter about airline plots that might be connected to this. Were there things we saw earlier but didnt make the connection and now with this missing plane there may be a connection . Are there groups taking responsibility . Sometimes that can be misleading. So were looking into all of this. Weve seen also cases in the past where there were psychiatric problems among the pilot or crew. That could be cause and factor. It still could be a mechanical failure, but were going to be obviously scouring all the intelligence leads while we search for the aircraft. What are you hearing about the pilot and the co pilot . Not very much. They were both very experienced. I think the early analysis looked at whether this was a problem with their training, did they not have enough hours in the air. Was this similar to the situation of the plane that crashlanded in san francisco. But, you know, the pilots look welltrained. The airplane looked like it was in good condition. The weather was good. This is why it was so mind boggling this plane has just completely vanished. Are you getting the kind of cooperation from the malaysian authorities you would anticipate in a situation like this . I raise the question, because some have criticized malaysia for giving out all sorts of conflicting information. You know, i think were getting good cooperation. I havent heard of any problems, probably the biggest concern is not the cooperation were getting now, but the fact that so many countries dont check the interpol database. So they dont look for these stolen passports. We and other countries, not all countries, but certainly we and the british and others make sure that we tap the databases that can tellis whether people are flying with stolen documents. And these two on this plane may have been completely innocent of the downing of the plane. But it doesnt mean that this is not a gaping security of vulnerability that needs to be fixed, because it could lead to terrorists to take advantage of this in other cases. Adam schiff, as a member of the house intelligence committee, congressman, thanks for joining us. Thanks, wolf. Aviation experts have some theories about what might have happened to flight 370. Were going to talk to a former managing director of the ntsb about possible scenarios. Thats coming up.

And the breaking news, some more mysterious information just coming into cnn from the Malaysian Air force. The Malaysian Air force says it has now traced the last travel of Malaysia Airlines flight 370 to a very small island in the straits of malacca, according to the senior Malaysian Air force official. The official declined to be named, because hes not authorized to speak to the news media. But the official says that about 2 40 a. M. Local time, the civilian and military radar lost all contact with the aircraft, strait of malacca is in a body of water that separates the peninsula from the indonesian island of sumatra. Its many hundreds of miles from the usual flight path for aircraft traveling from kuala lumpur to beijing. So it was way, way off course, according to this Malaysian Air force. No explanation, obviously, given. Still no sight of any debris. No sight of this airliner. Peter goels is joining us right now, former ntsb managing director. So the this air force official from malaysia, peter, is now saying the plane was hundreds of miles off course from where it would have been going if on a normal route from kuala lumpur to beijing. What do you make of that . Even more perplexing. I think it starts to narrow the options down. If this report is true, it means a couple things. One is, was there someone unauthorized in the cockpit ordered the transponder turned off, ordered the plane to fly, you know, 90degree turn off course. Second is did one of the pilots do it themselves . Is this something that was commanded by one of the flight crew . Its really increasing the concerns. But youve got to zero in now on the flight crew and their background. Were they in any kind of financial difficulty . Were there other concerns being raised . And youve got to go look at who was on that plane. The two pilots, one i think 53 years old, very experienced. The younger co pilot, 27 years old. Obviously a lot less experienced. Both malaysian pilots. Both seemingly with good reputations. But there have been histories, and you can remind us, of when pilots deliberately wanted to bring down their aircraft. Im referring to that Egypt Airline crash and that silk airline crash. Tell us about those. Well, both. In both cases, the ntsb determined that the pilot took control of the aircraft and in the case of silk air, turned off the flight voice recorder and dove the plane from 30,000 feet into a river. He disabled his co pilot. In the egyptair, the co pilot took control of the plane while flying pilot was out of the cabin on a rest room break. They actually got into a struggle in the cockpit to get control of the plane. And unfortunately, the co pilt pilot turned the engines off and the plane crashed into the north atlantic. So you do have two cases where pilots have deliberately flown their planes into the ocean. And is it that is it that easy, peter, to simply push a button and the transponder goes off and then no one can monitor where that plane is heading . It is not difficult. You can either you can either turn the transponder off in the flight controls and in front of you. You can because you can use it to squawk for a hijacking. Or you can turn the Circuit Breaker off, which would shut down both the transponder, you can shut down the voice recorder, you can shut down access to the data recorder. So and then in the case of silk air, thats precisely what the pilot did during the final moments of that flight. Hold on for a moment. Because i want the you to react to this next report. Andrew stevens is joining us now, correspondent in kuala lumpur in malaysia. Up date our viewers, andrew, what were learning precisely, and what it may suggest. Reporter well, were hearing, wolf, now the last reported position, last position the plane was seen, was over a small island in the strait of malacca. This is on the subpoena sit side of the country of malaysia to the flight path where its supposed to be going. What we can tell you at this stage is that the plane officially was last contacted and was last seen at a way point heading towards vietnam on its way towards beijing. Then the transponders apparently were switched off. The second it was still able to be tracked by radar. Its called primary radar. The plane then did what apparently looks like a uturn, went back across the country of malaysia to the other side, the west coast, which is the strait of malacca, and was last seen on radar over a Little Island which is in the middle of the strait of malacca, between malaysia and indonesian, about 200 kilometers or so, 150 miles off the west coast of malaysia. Thats what were hearing at the moment. We dont know what happened then. But the actual plane disappeared, the radar contact disappeared at around about 2 40 a. M. Thats about two hours after it took off and about an hour after the its last official position, just as it was entering see aetna mays air space from Malaysian Air space. So from this point, looks like evidence is growing, the Malaysian Air force, were hearing weve been talking to a Senior Air Force official here. He cant give his name, because hes not hes not responsible for speaking to the media. But certainly he is telling us this is what the situation is, where this plane went. So were talking about looks like basically a uturn back across to the other side into the straits of malacca. So basically what youre saying, andrew, based on this information from this Malaysian Air force official, the search under way for four days, that search has been going on in totally unrelated waters, right . They havent even started this search, if you hear where this plane disappeared, this Malaysian Air force official, saying it disappeared hundreds of miles away. Well, no, wolf. They have been searching in that area, gradually expanding the search, expanding the search. They began the search looking over the last known contact point of that plane. But as the days have gone on, they have started searching across the straits of malacca. Its been a little bit difficult to follow, because the authorities have obviously been aware of this for some time but havent let this information out. But by looking at what theyre doing with the search pattern, that pattern has been going further and further out across the straits of the malacca, into where that air where that plane was last seen and sort of unofficially, if you like. Just from my understanding of this, wolf, when the plane was last officially seen, the transponders were on. I
