Show me all your hands, hands up, heads down heads down heads down, hands up heads down, heads down this is what passengers aboard sunwing flight 772 from toronto to panama city heard after a truncated flight that included threats, a fighter escort, and what you just witnessed. Pamela brown has all the latest. She joins us now. So what we do know . What happened here . As we saw, anderson, it was a chaotic scene moments caught on a passengers cell phone as a s. W. A. T. Team stormed a canadian airliner that returned to toronto after what the airline told us was, quote, a agitated passenger who threatened in the plane. The sunwing flight was only 40 minutes into its flight from toronto to panama city when one passenger made what the airline said was a direct threat against the aircraft. We listen to air Traffic Control audio. It appears it was a bomb threat. So the plane turned around as is the procedure, and two u. S. Military jets already in the air were dispatched by norad to escort it back to torontos airport where it made an emergency landing. And thats where the Security Team stormed the plane, anderson. They arrested a 25yearold male, a canadian citizen who remains in custody with police tonight. Hell have a bail hearing tomorrow. The plane was searched and nothing was located. There were no injuries or damage. The passengers got to fly out on another plane. But as you can imagine, they are still very shaken up from that experience. Anderson . And what is the passenger that made the threats charged with . Are there actual threats im going to bomb this plane. I thought they were more oblique like i dont like canada. I wish i could bomb canada. Authorities arent givens specifics, but we did listen to air Traffic Control audio, and they indicate he was making a bomb threat, but nothing more than that. We learned that he is actually facing four charges, anderson. He is charged with endangering the safety of an aircraft, mischief to property, mischief, interfering with the lawful enjoyment of property and uttering threats. And also his father spoke to a Canadian News Network and said that his son suffered from Mental Health issues. So that could have played a role. But again, hell have his bail hearing tomorrow. So well be keeping an eye on it. Scary moments. Pamela brown, thanks. The story raise as lot of questions. I want to get answers now from aviation analyst miles obrien and aviation safety analyst david souse it is. Miles, lets start with you. I want to show that video again. This is taken once the plane landed back in canada after being escorted by u. S. Fighter jets back to back to toronto. And then the plane was stormed. Heads down, hands up heads down, hands up heads down, hands up. Heads down, hands up let me see your hands heads down, hands up what is the protocol in this kind of situation . Patiently, thats the rcmp, Royal Canadian mounted police protocol. It looks a little excessive to me, frankly, anderson, given all that had happened. I can only say aye assume that if they flew 45 minutes back, that the passenger who made that threat had been neutralized in some fashion, had been handcuffed with zip ties, maybe a couple of hockey players on board to take care of him. Whatever the case may be. Otherwise you would think that the pilot would have put that plane down in pittsburgh or cincinnati. Having said that, given, you know, just the overall tensions in the aviation world and stretching everything back to 9 11, this is the hair trigger feelings we all have about flying right now. And that kind of manifests in that scene with the swat team coming on board. And david, i mean, the plane, as miles says, it was over West Virginia apparently. And when it turned around, does it make sense and then starts to be escorted by u. S. Fighter jets. Does it make sense it went all the way back to canada . First at this point, they penetrated the air defense zone. The adiz. That aircraft, until its proven is not a threat is a threat to the united states. So to land at philadelphia, land at cincinnati, the Risk Mitigation protocol for that would be to say how many losts would be lost if it did that if it really was a bomb. Youre saying under the protocol, they wouldnt land at a major city. No. Just because in the event there was some sort of an incident. Why risk thousands of lives on a poem bomb situation, although it does put the people on board the aircraft at risk, additional risk, because theyre in the air longer. Also, they did fly back, wasnt it to toronto . They did. Because they had to get away from the adiz. They had to get back out of the country. The adiz . The air defense identification zone, which is our defense border around the united states. So they consider it a threat. They consider it a violation or a breach at that point. Because it has an identified threat. As far as the u. S. Was concerned, they just wanted it out of u. S. Airspace . Well, they needed to get back where it had to be so they could control it from the country of origin. And thats what had to be dealt with at that point. Couldnt it have been landed at a small Regional Airport somewhere . Possibly, if that was what they decided to do. But i just want to make the point it was not the pilots decision. When youre escorted by jets, you go exactly where they tell you to go. You dont mess with it. And that defense was made by the air defense command, not by the pilot. Miles have, you ever seen a plane like that actually being stormed . Weve all seen training exercises where they do it, and weve seen it with u. S. Air marshals in training exercises. But clearly they felt there might be a real threat there. I guess that you have to operate with that presumption in this day and age. And that tells you a lot about how flying has changed for all of us. I think its worth remembering here that clearly, any captain, any pilot, they thought there was an immediate threat to that aircraft. I would submit to you they would put it on the ground. They could declare an emergency and put tonight ground, period. So im going to assume that this threat, one way or another, had been neutralized by passengers. And i think its worth pointing out from shanksville, pennsylvania, the shoe bomber and the underwear bomber and a number of other instance, passengers have really taken up the last line of defense in aviation these days. Yeah. Theyre attuned to the threat, and theyre not going to sit by and let these kinds of things happen. Its an unsung hero in the process. Where is it, david, in your experience for Law Enforcement to board and aircraft like this. To what . To board an aircraft like this. Have you heard . Oh, yeah. Every time there is the suspicion on board that aircraft. Its just because it was caught on video makes it so startling. Absolutely. The same thing happened when one of the pilots went out of control not too long ago. It was stormed with s. W. A. T. But with agents. The s. W. A. T. , that isnt something im familiar with, but others are. Interesting of, david, miles, thank you very much. Were going to come back to them shortly because there are other developments. So much aviation stories right now. We go to mali right now and the crash site of air algerie. It is a stark contrast to the scene in ukraine, which well also bring to you. French forces have secured the debris field already. A helicopter located the wreckage near the board were burkina faso, all within 24 hours of the crash. As with flight 17, no survivors. An Airline Official Said 116 people were on board. Tonight there is still no definitive word what brought the plane down. The bad weather is a prime suspect right now. Joe johns brings us up to date. What are we learning . The first pictures from the scene basically show a field of debris. The authorities are saying its so bad, its going to be difficult to try to reconstitute the bodies, human remains scattered all over the place. To preserve the evidence, there are military units from france and mali as well, trying to restrict access to the area. But when you look at this, it seems like there is not a lot to work with for investigators as they try to determine the identities of the victims, what caused the crash. But there is still confidence on the ground that they are going to be able to figure it out. And frances president i understand, joe, spoke about the situation. What did he say . Well, he said the planes debris field is concentrated in a limited area, but its still too early to draw any conclusions. But that the information is going to come in time. He said there are some theories, including weather conditions as a cause. But theyre not putting anything aside, because they want to find out exactly what happened. And there are, of course, some open questions, especially that question of whether an act of terror was responsible. Frankly, though, the authorities are skeptical that islamist rebels in the vicinity actually had the technology to bring down a plane at a high altitude. Meanwhile, the families of the victims are still trying to get some details. Yeah, of course. Joe johns, thank you very much. As we reported, air algerie disappeared after changing its flight path because of bad weather. Fierce thunderstorms were pounding the region at that time. That time of the world this time of year that is not unusual. Miguel marquez has more on that. Reporter flying into any storm can be a bumpy white knuckling experience. But flying into bad weather near the equator can be a nightmare, known as the intertropical convergence zone, a band of unsettled weather around the earths equator where some of the most ferocious storms can develop. Youve flown in a lot of storms. Ive flown in more storms than id like to. And what is it like to fly into a serious thunderstorm . Well, it can be anything from, you know, mr. Toads wild right to the most harrowing experience you can imagine that you dont think youre going to get through it. Reporter its saharan africa. Powerful sand storms are the product of that intertropical convergence zone, a challenge for any pilot. This pilot coming in for a landing goes directly into the storm. You can hear the engines rev as the plane enters the stand storm. The sky turns red, visibility zero. Weather is suspected as the cause or contributing factor in the crash of air algerie flight 5017. There was trouble on the radar, a massive thunderstorm moving right through 5017s flight path. The 18yearold Mcdonnell Douglas aircraft departed Burkina Fasos ouagadougou airport at 1 17 p. M. On the way to algerias capital. To get there it had to cross the ittz, the band of unpredictable weather around the worlds equator where terrible weather can develop. Flight 5017 asked if it could change routes. The plane made its way east and then north again. Last contact, 17 minutes later near gao, mali. Just maybe an eerie similar to air France Flight 447. 228 people on borden route from Rio De Janeiro to paris on june 1, 2009. Pilots on the airbus 330 were flying through an enormous storm spawned by the intertropical convergence zone. If you fly underneath, that that could be some of the most dangerous parts of the thunderstorm. Reporter intense winds coming down at you from Different Directions . And hail. Reporter flight 447 was more than 30,000 feet over the atlantic. The storm shot up to more than 50,000 feet. The pilots added power, climbed. The plane stalled, losing all control and slammed into the ocean from 38,000 feet. The crash of flight 447 pound to be pilot error. What caused flight 5017 to crash now under intense investigation.

Even as the netherlands, which lost so many people on the flight are pressing to send their own police and experts to the scene, the prorussian rebels that control the crash site say theyre getting tired of any investigation there, period. If that werent enough, there is word that russia is sending them more weapons and shelling the area from russian soil. Barbara starr has more on that now. She joins us from the pentagon. What do we know about the russian weaponry . Good evening, anderson. Well, the shelling from the russian side into ukraine continues into g according to u. S. Officials. And now today the u. S. Says it has intelligence that shows russia is about to send additional heavy weapons into ukraine, into the separatist held area. This is going to be something called 220 millimeter multiple launch rocket systems. Heavy weapons with large warheads. They could go about 20 miles. This is going to give the separatists once they get their hands on it from the russians the ability to escalate the ground war once again. And as always, it is very likely its going to be the citizens, the civilians of Eastern Ukraine that may pay the price and get caught in the crossfire. From the pentagon perspective, how much of an explanation is this . Well, the pentagon today said they do consider this a definite military escalation by russia. And its really the unanswered question. What is Vladimir Putin up to. How far is he willing to go . Hes got 15,000 troops on that border, firing from both sides essentially. The question is, you know, is he going to respond to the sanctions that the west and the u. S. Is putting on him . Is this all going to cost him too much that he will ratchet back. No indication that putin is about to respond to the sanctions. And that is the only strategy so far. Anderson . All right, barbara starr, thanks for the update. More now on the crash site itself. Weve all been astonished to learn this past week resembles little anyone has ever seen. International monitors say they have had easy access to the fields of wreckage and almost certainly more human remains. The problem, there is also easy access to just about anyone, whether they belong there or not. Ivan watson has been there. He he is in donetsk for us tonight. Ivan, more than week after mh17 is shot down, the site is still not secure, still controlled by the rebels. I just heard shelling behind you. Is there a sense of when this is going to happen, when this site might actually get investigated . Well, the international monitors from the osce have been going day after day to the site. They were accompanied by australian and dutch experts, less than a dozen in all. On todays visit. They say that they uncovered some new debris that they hadnt seen before laying in the middle of a village. And they also heard that some of the separatists leaders were telling them that theyre getting impatient, that they want a bigger body to come and start to remove that debris, a bigger body of International Experts because theyre running out of patience. And that probably has to do with the fact that the war here in Eastern Ukraine is intensifying. Given the ongoing violence and the uptick in violence, and i hope im wrong here, i just dont see how there is going to be a large footprint of australian and dutch police and investigators cordoning off several mile radius area and systematically searching for victims or searching through wreckage. Can you foresee that actually occurring . You know, a couple of days ago, we were traveling freely back and forth from the crash site. The separatists had opened the way. Some of the initial obstacles had been lifted and the question that was raised, why arent people starting to show up . I think were learning very quickly just how combustible and unpredictable the situation. Youve had a couple of ukrainian warplanes shot down just within the last three days. The fighting is clearly intensified. The proposal to send potentially scores of australian and Dutch Military police and investigators perhaps some of them armed, i dont know how thats going to work in a very complicated place like this. How you can get both the approval of the Ukrainian Government and the rebels who are locked into this deadly struggle together, for them both to agree for some kind of humanitarian corridor for another foreign potentially armed body to come int
