on twitter. be sure to join us again monday right here in "the situation room" room". you can watch us live or dvr the show so you won't miss a moment. thanks very much for watching. have a good weekend. erin burnett outfront starts right now. next breaking news, isis makes a makes a makes a bold claim that a jordanian air strike killed a american hostage. did the pilot in the taiwan plane crash shut down the wrong engine. we have new information from the plane's black boxes. the jury in the aaron hernandez trial gets a tour of his home and the crime scene. how damming was the evidence. let's go outfront. good evening. i'm erin burnett.

isis charges that an american hostage, a 26-year-old woman has been killed by a jordanian air strike. the terrorists offered no proof of death, no photo of a body. they claim she was killed in the bidding you see here. the american hostage's family identified the woman as kayla mueller captured in august of 2013. they insisted they have not seen anything that corroborates isis' claim. we're also learning that isis in syria has developed plans to kidnap more westerners in neighboring countries including lebanon and jordan and bring them into syria. we'll have much more on that development in just a moment. i want to begin with barbara starr at the pentagon. the building isis says was hit killing just one person

26-year-old kayla mueller. what do you know? >> tonight u.s. officials are scouring everything they have for any intelligence about what really happened here. if you look at the isis claim, they claim this young woman was the only person killed in this jordanian bombing run. what are the chances that a hostage was left in this building on her own, no security nobody watching her and that no one else was in this building building? that's the first data point that doesn't add up. there's simply no corroboration about what happened here. there's an awful lot of people that will tell you that one of the working theories is very sadly it's possible she was killed by isis some time ago and now isis has developed this cover story, if you will to shield itself from what would be international condemnation for

having killed a woman. they don't want to be out there. another step too far. the u.s. government looking for any verification any clues they can offer her family. >> you've always found out there was a raid this summer as we know. special forces tried to rescue americans. among them james foley who ended up being beheaded in one of those horrible videos. they found evidence that might have indicated kayla was in that location. what do you know about that? >> right. let's revisit that quickly. last year u.s. commandos went to a site in syria where they had information that the hostages mr. foley and other hostages were being held. this was quite a daring raid. very dangerous. they went in they did not find any hostages there but they found evidence that the hostages had been there and of course moved. one piece of evidence there were writings on the cell walls.

they also found dna, hair sample samples samples. sources could not confirm one of the hair samples was from kayla, but the washington post is reporting it was her hair. >> it will be a significant development. they are desperately trying to find out if she's alive. where she might have been killed? who was kayla mueller, the 26-year-old woman isis says was killed overnight. >> i'm in solidarity with the syrian people. >> reporter: 26-year-old prescott arizona kayla's passion for helping people is what brought here here 2011. she took part in this video declaring her support. she's seen in this you tube video addressing senator john mccain. she volunteered with the support to life organization in turkey where she helped people living

in refugee camps. in 2013 she was credited by her daily newspaper for helping a 6-year-old boy find his family. i will not let this be something we just accept. in high school she volunteered with the save darfor coalition. she was recognized as a national young leader. she told the daily courier in 2007 i love cultures and language and learning about people's cultures. after graduating from northern arizona university in 2009 she lived and worked with humanitarian aid groups in india and the middle east. in august 2013 she was kidnapped in allepo where she was leaving a spanish doctors without borders hospital.

>> isis has been collecting foreigners for hostages. >> reporter: after the beheadings of three american hostage, she would be the last known american hostage held by isis. pamela brown, cnn, washington. >> what is the reaction there tonight? i know they had been hoping against hope. they were trying to negotiate safety for their daughter. >> reporter: what we're hearing from everyone here is confusion, profound sadness and fear they're going to say the wrong thing. for that reason many of the people who know her here have declined to speak on camera. the family has requested priefr privacy. they did want to share this with cnn. that their daughter tried to live her life with strong leadership, quiet leadership and a desire to help others.

it's here. she volunteered in hiv shelter. she helped women at a women's shelter. she traveled the world with aid agencies in india, israel the palestinian territories. it was one conflict in syria trying to help the refugees and the children that broke her heart the most. she said she refused to give up on them even if the rest of the world had. the family is trying to sort this privately. they're trying to sort this very complicated story of war, of international politics. for them and this town, this really comes down to the fact that this is their child. >> their child. so hard for them to imagine someone who tried to do sufficient good could have been the victim of such evil. thank you very much. served as senior advisor to george w. bush along with a cnn terrorism analysis.

paul, you broke the news that i mentioned at the top of the program. isis has been working for months on plans to kidnap westerners in neighboring countries. obviously, very significant because a lot of those countries are places people go to see some of the major sights of the world. americans go there all the time. what more have you learned? >> that's right. they have been developing these plans since the middle of last year. this is an isis outfit base. the idea they have been having is to snatch westerners and internationals from neighboring countries. places like jordan and lebanon and bring them back across the boarder into syria so they can hold them as hostages and use them for this terrible propaganda. there's also a lot of concern about egypt. this new isis affiliate that there's a lot of western tourist, american tourists. a lot of concern that group may try to snap westerners like isis has done in syria. >> it is very terrifying. even within egypt i know they

killed 26 military members. member don't pay as much to egypt as they should because tourists do go there. do you think isis may have more american hostages at this time? is it possible? >> there's no indications they have anymore american hostages. they have a british hostage. he's been appearing in those propaganda videos. >> they sort of turned him into a reporter of theirs. >> they're forcing him to do that. there are two american journalists still missing. not clear where that are are. which group might be holding them. concern about their status. now it may be that the groups pivot to try to snatch americans in other countries and this affiliate in egypt. they actually killed an american in a carjacking this past summer. >> is there any possibility that kayla mueller is still alive?

>> absolutely. i think that we shouldn't assume anything. there's reason to believe that they are desperate and there's a lot of theater going on in the wake of the jordanian hostage being burned. this is a group that you can't trust. right now they could be very desperate. anything they can do they will try and do right now. i think we should prepare accordingly. >> i know the family and then everyone watching is hoping for a mirror cal and hoping what dana is saying is possible. paul isis did release a statement saying mueller was dead. they said the building all these things that did seem rather hard to buy, didn't seem to add up. will they lose credibility among their followers if their claim is not true? >> yeah. if she pops up alive, of course they'll lose credibility. this was an official claim by isis. they put this out and another media division linked to isis repeated the claim later in the

day. a lot of pro-isis twitter accounts have been buzzing with this. >> dane, so many people said this week that since isis was willing to burn a muslim man alive that the group would be willing to murder a woman. they said there's nothing they won't do. prior to that there were questions. that isis might spare her from a beheading because of her gender. do you think isis is blaming her death on this air strike in order to avoid having to kill her. in other words is there a line that isis doesn't want to cross in. >> for them i don't think there's a whole lot of lines. i think we inserted ourselves in a way that we're getting to witness and they're showcasing the way they deal with each other before we got there. now we insert ourself, they're going to bring us into the mix. they want to have bravado theater shock to add to their campaign of recruiting and it's

working. it tends to backfire. we know that when it comes to long term analysis. >> thank you very much with that breaking news. next just how precise are these air strikes? we'll show the weapons being used and exactly how the targets have been chosen to so far there's been more than 2,000 air strikes in the war against iraq and syria. did the pilot's accidentally crash the plane because they shut down the wrong engine? aaron hernandez, the former nfl star on trial for murder. what did the jurors see inside his home and at the crime scene today? there's nothing more romantic than a spontaneous moment. so why pause to take a pill? and why stop what you're doing to find a bathroom? with cialis for daily use, you don't have to plan around either. it's the only daily tablet approved to treat erectile dysfunction

the claim from isis that a air strike killed the 26-year-old hostage. they said she was in the woman. some have raised questions. that building would have been smoking if it was just hit by an air strike. there are many questions being raised.

i know there's a lot of skepticism about whether this woman was killed in the air strike. what are they saying where you are? >> reporter: that's exactly what jordan jordanian officials are saying. they are describing the isis claim as lies a pr stunt and says it does not add up. isis deceived them and the pilot was dead. the jordanians say why trust the claim. there's fear they are trying to embarrass jordan and trying to create these rifts within the u.s. led coalition. something jordan says isis has been trying over the past few weeks. they tried to do this internally

and trying the make people blame their government for being a part of the coalition and ending up in that hostage crisis. the timing they're saying why is this happening now as jordan is upping that military campaign against isis they feel that isis is responding with this propaganda campaign. >> jordan went ahead with air strikes today. is there any sign they will pull back because of this claim? >> reporter: it's the complete opposite opposite. we see a real determination from jordanians from the government and officials. they're saying this is just the beginning of their retaliation for the killing of the pilot. the father said the king said they will bombard isis strongholds until they destroy

the group. there's so much support for the government and the king's efforts to go after isis. >> thank you very much. reporting live from jordan tonight. coalition forces have carried out 23 strikes. how precise have they been? tom foreman is outfront. let's just start with the basic question. what kind of planes what kind of weapons are being used? >> reporter: when talk about the air attacks you have to talk about the f-16 fighter jet. capable of flying two times the speed of sound. it can also drop these 2,000 pound smart bombs sometimes for miles away from the target and hit them very accurately. this is the number one weapon being used out there. there's also been a lot of action for the a-10 wart hog. this is being used effectively against armored vehicles owned by isis.

look up in the nose. that's one of the biggest canons ever put onto an aircraft. it can fire armor piercing millimeter rounds. you can have part of the wing shot off, part of the tail shot out, the hydraulic system ruined and can still keep flying. we have to talk about predator drones in all of this. drones can be fitted with missiles missiles. we know that. they are not being used that much. these are flying over isis figuring out where they're strongholds are, where the troops are, where buildings are and directing all these other weapon systems in their attacks. erin. >> it sounds impressive. when you talk about the canon on

the front per minute. >> per second. >> the claim today is that isis says the jordanians hit a building and killed the american hostage. is such a thing possible given what we know? >> these are highly accurate. such a thing is possible because there's not a lot of good intelligence on the ground here. you can only tell so much from the air and there have been a lot of attacks out here. the u.s. hasn't been in charge of all of them. take a look at all the coalition forces involved here. there are a good number of countries here. make no mistake. this is not a coalition of equals. the united states is in charge of things here. if you look at overall numbers out here the total number of air strikes are pretty big. in iraq the u.s. way out front of all the coalition partners combined.

the u.s. is leading 80% of all the attacks against isis. can there be a police take? absolutely. there seems to be truly every effort according to military officials to not make those mistakes. >> thank you very much. incredibly value to hear that reporting. joining me now the retired air force colonel who served as an intelligence officer. colonel, you just heard the numbers tom was sharing. nearly 2300 hundred air strikes against isis. the united states has conducted the exact number 81% of them. arab coalition members, 3.5% of them. does the moderate arab world need to do more? >> well erin, i think so. they have the capability. they certainly have the money. the problem is they don't have the same doctrine that we use within the u.s. military and that's a significant difference.

not only do we have the doctrine for us to do these joint and combined operations but we also have the abilities and we've had the training to do this. the arab world has a lot of significant capabilities especially when it comes to some of the modern weapons but they don't have that overall architecture in which they can employ the weapons in a joint and effective manner. >> you mean the command center that tom is showing. these weapon systems and there's a single thing controlling it. >> that's right. it's called the air operation center. it's the one that directs combat operations. that system was used very effectively in first part of the iraq war. the second iraq war and it was the way in which we have really taken air power and integrated it fully into the joint effort to fight our wars. that's exactly what we need to do here. >> isis has doubled the

territory it controls in syria. there has been there's been no troops on the ground outside various rebel forces. when you hear about the president of the united states asking for that vote what does that mean? who's going into syria? >> i think it should be all of the above plus air power. what you'll see is broad idea that this is what we're going to do and then the details of it are going to be worked out in a way that will sew between the white house and the pentagon will show exactly what types of forces will be moved forward. that would include special operations forces and some infantry units. certainly marines would be part

of the mix and definitely air power. those are the things that would go into what happens after the authorization to use military force. >> thank you very much. next, aaron hernandez jury. they went to the crime scene today. full day on a field trip. they were driven to his home. what did they see? plus the taiwan plane crash. did the pilot shut down the plane's only working engine by mistake? what the cloud enables is computing to empower cancer researchers. it used to take two weeks to sequence and analyze a genome; with the microsoft cloud we can analyze 100 per day. whatever i can do to help compute a cure for cancer,

we're learning the pilots of deadly plane crash this week in taiwan may have shut down the wrong engine. just seconds before the plane rolled 90 degrees as you say in this unforgettable video clipping a highway and crashing into a river. at least 35 people died. 15 survived. just seconds after the plane

took off warning signs started blaring. in the confusion of trying to figure out what was wrong the pilots may have by choice cut power to the wrong engine. what was going on for those pilots? >> reporter: they're trying to work that out. they have revealed that perhaps the pilots on board the trans asia flight reacted by shutting down the wrong engine. it's a frightening thought. the pilots may have accidental shut down the engine or it may

have failed leaving the plane with no power before it crashed over a bridge just 3:22 after take off. just 37 seconds after take off the first of the five warning signals sound in the cockpit. they discover slowing down engine number one, the left engine. >> based on the information that came out of black boxes it's a combination of i thinken malfunction and pilot error. it appears they had a problem with unengine and were trying to overshoot it but naxenly shut down or rather throttle back on the other engine.

repeated stall warnings are heard in the cockpit. the aircraft is losing speed. with the flight spiraling out of control, the crew says they've restarted an engine but issue a december stress call. >> mayday mayday. >> reporter: a few seconds later the plane hit a taxi and the bridge crashing into the river below. investigators say the pilot and co-pilot were later found still in their seats clutching the controls. in an emotional interview the pilot's mother said she was proud of her son for saving the lives of the many people in the tall buildings. >> he was a hero. there are hundreds of people whose lives aren't lost because of what he did. pilots can only do what they're

trained to do. >> reporter: blame is not being assigned at this stage. the investigation is ongoing. if focus is switched from engine failure to pilot error. we may not have the official results of that investigation for at least a career.year. hundreds of divers are back in the water scouring it trying to find those remaining eight passengers whose bodies have still not been accounted for. >> thank you very much. richard quest along with our aviation analyst. miles, there's this crucial issue about the wrong engine got shut down. is it that easy to do that? the plane is telling you this engine has a problem and then you shut down that engine. is it that easy to happen? >> it is. it's happened dozens of times.

perhaps most notably in 1989. a 737, one engine out. the pilot did the same thing. shut down the good working engine. pilots are drilled to act precisely and quickly. in some cases it's good stop and take a moment and double check what you're doing. it's quite possible that the captain, who had some issues with the left engine before he started that flight might have been predisposed to think he had a problem with the left engine and might have done that or might have just not crossed check it well with the first officer. >> maybe he thought the left engine had a problem so he was in that quick second hit that engine. >> they knew that number two engine had gone. they discussed throttling back on number one. they confirmed that number two wasn't working. then they cut back on number

one. they clearly intended to cut back on an engine. did they realize that either which one it was or b, they hit the wrong button. >> obviously, seconds before the plane crashed in the last few seconds they tried to start that engine up. they successfully start up the left engine but it was too late. there's nothing you could do. the plane had started turning. >> it would take many seconds to build up to speed and to generate enough lift to get the aircraft up. the midland, 1989 was the classic example of switching off the wrong engine. changes in procedure and manufacturer and design of the cockpit was put in place to prevent this from happening again. in the seconds that we're talking about here. >> miles, i guess i have another question about this. if one engine is shut down or

malfunctioning is it possible would it be smart to put something in the cockpit to turn the other off to prevent this from happening? >> i think it would be smart. the ergonomics of this make it much easier. the gauges are close together. the throttles themselves are couple. they're right beside each other. very easy to make these mistakes particularly when you're in a dynamic boardering on panic situation. this is a critical thing at low altitude and marginal speed. you have to do everything just right. you the imagine not thinking thingings through clearly because you don't feel you have enough time. >> no matter how trained you are you know you're about to die. you can never train completely for that because even in training environment you're not about to die. richard, satellite image of the buildings. they missed those buildings. the plane came down over the water. did they have any way to steer,

have control at that point? >> my guess is every pilot is going to do the best they can to avoid the buildings, if possible. if you listen to the transcript or see what was going on they were just doing their best to keep that aircraft in the air. i don't wish to take away from anything that happened in that cockpit but my feeling is you're talking more about good luck than good management that he didn't one of those buildings. >> thanks so much to both of you. next nbc news launching an internal investigation into brian williams discredited war story. could the anchor be suspended or more? the super bowl dancing sharks. nobody took them seriously exsentex except katy perry and her lawyer. a little too honest sometimes. the media is useless. you were out of control.

helicopter hit by a rocket grenade. he was on a different yell kopter that was not hit. for two nights there's been no mention of the growing controversy on the nightly news. how long can brian williams go without publicly commenting more on this? >> it's been 48 hours. we did hear from the president of nbc news. she said there's an investigation going on internally. it's not an independent investigation. it's being done by the head of the investigations depts at the news division. someone who knows him well and pitches stories to his broadcast. people are asking how can there be an investigation if it's not being done externally. i think this has gone from bad to worse. >> i want to apologize. >> the conversation is only getting louder. ten years ago tom brokaw seated the big chair.

now he's denying reports he wants him out. his fump is up to brian and nbc news executives. a statement is more supportive from dan rather. i don't know the particulars about that day in iraq. i do know brian. he's an honest decent man. dan rather has had his own controversies when it comes to troouts truthful reporting. >> i made a mistake of recalling the events of 12 years ago. >> reporter: he's not the only one having dribble drive with

the fine details. yesterday he told cnn the helicopter did come under small arms fire. now he's not so sure. several other soldiers say he was piloting a different helicopter in the area. he says his nightmares about the war are coming back and he just wants to forget. perhaps the only one who can clear this up is brian williams himself. >> a lot of these investigations are usual external the dan rather one was. nbc has come short of fully supporting brian williams. >> that's what i thought was most notable. she sent a memo to her staff talking about the tight knit family of the news division. the rest of the tv industry is talking about whether he will keep his job. it's an extraordinary change of events from the past 48 hours.

i'd be very surprised if he was to leave the nightly news chair. the fact that it's being talked about shows how damaging this has been to him. >> damaging and how quickly things can turn. >> thank you very much. next, the jury in the trial of former football star aaron hernandez. what the jurors saw at his home and at the crime scene? they took a field trip today. cnn was there.

and now let's check in with anderson for a look at what's coming up with ac 360. >> indications that isis may escalate the fight threatening to grab more western hostages. we'll talk with someone who knows what it's like to be held captive, knows what kayla meuller who was snatched and held by isis went through. joined by journalist david rode who survived months at the taliban before managing to escape. more on isis claims killed by jordanian air strikes, mike rodders, former chair of the house committee is on the program, skeptical of the claims as many others. also an incredible story tonight in maryland. a 13-year-old girl watches her father struck by a car, calls 9-1-1, did the right thing and told by the dispatcher the 9-1-1 dispatcher told to stop whining. tell you how that turned out at the top of the hour. >> anderson looking forward to

it. the murder trial involving aaron hernandez spent the day on the road. police escorted the jurors to hernandez's home and to the industrial park where prosecutors say the former patriots receiver murdered his friend odin lloyd. the jurors trip to the crucial locations lasted four hours and our susan candiotti was there. >> reporter: a field trip that's all business. requested by prosecutors and defense, the aaron hernandez jury escorted by bus in a police motorcade for an up close view of evidence that might make it easier to understand the case. in court, prosecutors give a preview. >> we're going to direct your attention to a cell tower that's located in that area. >> reporter: the jury sees four cell phone towers that prosecutors say generate signals along the route, the former patriot tight end takes with odin lloyd the night he is murdered. next stop outside odin lloyd's

home. during the jury tour, prosecutors point out a security camera at the house across the street. it captures this surveillance video of lloyd getting into a car investigators say is driven by hernandez. hernandez is not allowed on this trip but the jury gets to see the spot where prosecutors say odin lloyd's bullet-riddled body is found in this industrial park. after about 15 minutes, they head for hernandez's neighborhood. the jury's bus tour winding up here at aaron hernandez's home they're inside right now, well prosecutors and defense wanting to show up the home security system including 12 cameras. it's going to be critical evidence in this trial. they also the defense, that is had to remove various football memorabilia and family photos that were not there in june of 2013 when hernandez is arrested for lloyd's murder. inside the home they also see -- >> the kitchen area and then the

living room and pointing out certain features of the layout of the home. >> reporter: including the great room seen in this surveillance video of hernandez's fiance and her sister recorded a day after lloyd's death. jurors also see the foyer where hernandez is photographed moments before the murder and prosecutors say, holding the murder weapon that's never been found. >> susan, i know there were some issues before the tour today when jurors went to see the home about what the jury was going to be allowed to see. prosecutors were worried. why specifically? >> >> reporter: prosecutors were pretty angry after they got a preview of what the house looked like shown by the defense because prosecutors said hey, it does not look like it back in june of 2013 implying that the defense had changed what the house looked like. the defense did remove all extra items from the house, like i

mentioned, football memorabilia and photos but absolutely denied that they were trying to manipulate the jury in any way, erin. >> susan, thank you very much. susan, of course giving you the details of everything she saw today. outfront now, our legal analyst paul callan. i want to start with what susan showed. photos memorabilia, things given a personal feel. that's partially because of the o.j. simpson trial because of what they felt in the home. >> it's highly reminiscent of the o.j. simpson trial. the jury was taken to the trophy room and it sort of exaggerated his role as a sports celebrity and gave them -- >> power and authority and invinsability, maybe? >> yes, which has nothing to do with how the murder took place and the only reason they're even going to the scene in this case

is to demonstrate the proximity of the house to the murder scene in the industrial park only 3 minutes away. >> i could see why the prosecution would want them to see it. it's three minutes away but the defense also wanted the jurors to see this home. so they both wanted it. so who do you think actually gained the most by jurors seeing it? >> i think the prosecution gains here and it's going to come back to this. when the car, the nissan enters the industrial park, there are four men in it. one is aaron hernandez driving. when three minutes later, after gunshots are heard, it enters the garage of aaron hernandez, there are only three men in it and one of them of the previous men is shot to death in the industrial park. so that's only three minutes away. the jury actually experienced that because they drove from the scene to the house. so i say this really helps the prosecution, not the defense. >> all right. we shall see. thank you very much to paul callan. outfront next katy perry's

dancing shark. we told you about this story earlier this week and, well, you know for katy perry, this is nothing to laugh about. that's next. the real question that needs to be asked is "what is it that we can do that is impactful?" what the cloud enables is computing to empower cancer researchers. it used to take two weeks to sequence and analyze a genome; with the microsoft cloud we can analyze 100 per day. whatever i can do to help compute a cure for cancer, that's what i'd like to do. ♪ ♪ ♪ ♪ ♪ ♪
