our justice correspondent, evan perez, is joining us now. evan, you have some new information. >> well, yes, wolf. we know from the government from the latest government briefings that the u.s. believes it has enough information to indicate that the heading of the aircraft, when it deviated course from its scheduled -- from where it was scheduled to go to beijing, somewhere over the gulf of thailand, it decides to start heading west. and that course was set using -- via the input via the computer that controls the aircraft. now, who did this, you know, when was this done exactly, that is still very much an open question. but we know that there was enough data that was being sent in during the first 40 minutes of this flight that the government now has and is taking a look at. and that information indicates that the specific course -- there was some specific coordinates that the aircraft was heading towards. and those were specifically inputted in the flight computer system. now, i'm not sure -- i'm not an aircraft engineer, so i don't know al

we begin our live coverage with evan perez. >> evan perez there has been a lot of criticism that they haven't handled this properly. we are in day ten now there seems to be a lot of frustration. how about in washington? has there been a lot of frustration in the way in which this is moving? there are a couple of thing that is people have to recognize. the chinese probably have more of an interest than the u.s. does. there is somebody from the embassy who is there. there is a limit to how much the malaysians have shared initially. i'm told that has improved. but right now there is no plane to look at. the fbi is sort of limited anyway in what they would be doing on the ground. there is recognition of you no as chad described. there is a lot of facts that aren't known yet. so when we have that perhaps you will see involvement. let's talk more about some of the things that we do know if we can. because we can go in all kinds of directions. we know that the transponder was turned off and we know that was deliberate. and we know about this last comment, good night. is there anything else t

i want to bring in evan perez and both are in washington. thur rosen berg, a pilot and engineer here with me on set in new york. first to evan. tell us about this lithium battery report. they are trying to go through the latest information from malaysia. that indicates lithium batteries in the cargo area of the airplane. whether or not it caused a fire, they don't know. that is one thing being examined at this point. they don't know for sure if this could explain it. it is one of the things they are looking at. there has been a problem previously with the lithium batteries in 2010. there was a u.p.s. plane crash in dubai they believe it was being carried in the cargo. this was a concern for aviation safety officials around the world for sometime. the faa for instance doesn't allow it in your checked baggage. the lithium batteries for this reason. there has been over 100 of them. this is something that they are looking at. this is one of the many theories they have. as you and i have talked about, there parts of this that are not explained. wh

first i want to go straight to cnn justice reporter evan perez. he's in punishment. evan, hello to you. you've been all over this part of the investigation. what can you tell us about this very latest development? >> randi, the latest is changing the understanding of what happened and when. today the malaysian government said last transmission at 1:07 a.m. from the jet's acars communication system showed, quote, normal routing to beijing and, quote, nothing unusual. this is important because it appears to undercut the theory that the flight path reprogramming took place before the copilot says all right, good night. that's the flight's final transmission with air traffic control at 1:19 a.m. this reduces but does not rule out suspicions about the foul play in the cockpit. randi all this adds to the mystery that riveted all of us about what happened aboard flight 370 two weeks ago. >> you're saying we can't rule out anything at all from this. >> that's right. investigators here in the u.s. and malaysia still have many theories they are wrestling with partly because the

our justice reporter, evan perez, is joining us now. an, what do we know about these batteries, specifically on this flight, 370? >> reporter: well, wolf, we know that the malaysian authorities told u.s. authorities last week that these -- there was a shipment of these batteries that was on the flight. now, they don't believe there was anything nefarious, no foul play suspended in placing these on there. and, you know, but this was one of the first things that raised some eyebrows, some suspicion among u.s. officials. especially intelligence officials who thought that perhaps, just perhaps, this could be an explanation for flight 370 disappearing. now, that still hasn't been confirmed and we don't know more about what exactly this cargo was. but we do know they were on the plane, wolf. >> what are the regulations surrounding transporting batteries, these lithium batteries, in the cargo hold of planes? >> well, you know, they're very tight regulations. for example, if you're a passenger, you're not allowed to put it in checked luggage, fo

i want to go to justice reporter evan perez. what have you learned?porter: we learned that u.s. investigators have been examining the hard drives, as you know, seized from the two pilots and the hard drive belonging to the captain has yielded some information that appears -- it appears that they deleted some information -- someone deleted information after february 3rd, which is when, as you might remember, malaysian authorities have said they noticed some deletions done from the hard drive. we don't know and what investigators are trying to figure out is who made those deletions, when particularly the deletions were made and whether they went right up to the departure of the flight and whether or not there's anything nefarious in this. now, this could have been done by someone doing the initial investigation of the hard drives, as you know, so that's something that they are not making any conclusions about, jake. >> evan perez, thank you so much. >>> two full weeks have ticked by and that make it is all more puzzling why four days went by to make the

he ha evan perez, thank you for the live report from washington. live in new york, with more on the actual technology is brett larson, cnn analyst and host of the web cast and syndicated radio program tech bites and also joining brett and me, once again from our virtual cockpit in canada, joined by cnn's martin savidge and flight instructor, mitchell castado. brett, first and foremost. when we hear the fbi is now combing a hard drive of a flight simulator, how much can you comb? what kind of forensics can we actually get out of this thing? >> you can get literally anything that was on that computer. so anything that he threw out. even if it was just as simple as his web history and he deleted that. that is going to show up on the marred drives. data goes on to a hard drive the same way frosting goes on to a cake. one layer at a time. and when you take a chunk of that frosting away, delete a file, it just creates room on the hard drive where more data is going to override it. >> if you're a person of this caliber, this is a tech guru. wouldn't he be

i want to bring in evan perez breaking the navigation story for us tonight. some of this can get really technical, evan. just to start with explain exactly what a way-point is and what is significant about this information we're getting. >> think about your gps. you can enter longitude and latitude in your gps to try to direct you, navigate you to a particular place. now in the sky for pilots, they also have to include altitude. so essentially it's a place in the sky where a pilot can direct -- to direct an aircraft and the computer system on board the aircraft to take the aircraft. and so the navigational systems on the plane essentially uses these five digit codes to direct where to take the aircraft, anderson. >> so explain the breaking news on this tonight. what is new that we now know? >> well, one of the things that we've been wondering is how the investigators know that the aircraft deviated from its course. we know there is some radar. but how can they know with certainty? we know that the investigators have discovered that the aircraft went to two spe

let's go to cnn justice reporter evan perez in washington. es to come out in just the past few days. but when these crews go out to, you know, do a visual confirmation of these items, these objects, they're not there. what's the value here? >> well, you know, of the fact that it keeps getting, we keep getting images, we keep getting indications that there is some debris, i think, is some sign of hope for the searchers that perhaps there is something there. as you know, the flights are dealing with terrible weather. some of the ships that were on scene had to be moved away because of very rough seas. so, this is not very easy. some of them are flying, some of the planes are flying very low to try to see if they can catch anything. this area is also known as a collection point for a lot of debris or a lot of the world's garbage end up right over in this area. that is what makes it so difficult. you know, until they can get some of this debris onboard a ship perhaps and examine it, they won't really know. but they have to keep looking, you know,

thanks very much to evan perez in washington.mentioned, airline security changed drastically after 9/11. earlier i talked with congressman adam schiff and i asked if this could affect airport security in the u.s. >> it is possible that it could lead to us even greater scrutiny of the crew of our aircraft if it turns out that was the problem here. but most of the vulnerabilities we have seen thus far are thing we have already taken action to correct in terms of making sure the people are not traveling with stolen documents. so i don't think we're likely to see a the love changes at home. the hope may that be we see improved airline security around the world as well as programs a better way of tracking aircraft. we'll be looking at those systems like the black box and trying to determine whether so perhaps the black boxes can transmit signals rather than having to find them under an ocean. so those are possible but i don't think you're likely to see it manifest in longer lines at the airport. >> i've been getting a lot of questions

>> we're gathering information from our sources and my colleague, evan perez, has said that files have been recovered after february 3rd. that's when the malaysian authorities said the deletions were made. we don't have a lot of critical information here, like when the deletions happened and who made them. the fbi did not receive the hard drive until this week, nearly two weeks after the plane went missing and consultants have been meticulously combing through that hard drive. they are looking for valuable and they are being looking at whether it was done in a routine manner which, of course, would be more of a red flag. s investigators are looking at information, such as a browser history, visit to chat rooms and online research that the pilots might have done, anything to help them build profiles of the two men flying flight 370. at this point, it's important to note that we have no information indicating that the pilots were planning the flight disappearance and it could be an insignificant part of the process. we just don't know. >> they are working hard to figure that out. thanks

i want to go to evan perez. you have covered this angle from the beginning. what can you tell us about this latest development? >> reporter: the latest information released by authorities is changing our understanding of what may have happened and when. the last transmission at 1:07 am from the communication system showed quote normal routing and quote nothing unusual. this is peers to undercut the theory that the reprogramming before the pilot said quote good night". this reduces but does not rule out suspicions in the cockpit. it rules out the mystery of what happened aboard the flight two weeks ago. >> authorities are now sharing the hard drives that longed to the pilots and what are they finding? >> in particular the one blo belonging to the captain, we have learned that there were deletions. this contained the flight sim y simulator that they have looked at. some were done after authorities began exsal am inning this. or some didn't enter the home. it is hard to explain this and i think the fbi is trying to figure that out now randy. a lot of concern tha

evan perez in washington, justice correspondent. thank you for joining us. mary schiavo, attorney for victims and families of transportation accident kip darby, pill, aviation consulting firm. clive, contributor for "the daily beast" and cnn analyst tom fuentes and david soucie, authorize of the book "why planes crash." a big panel. i want to start with the first question. viewers may be joining for the first time and learning this development about se quinquenci. malaysian horowiauthorities saye turn off course, raised questions whether this was a premeditated action by the pilots. i wonder if i could begin with you again, mary, your experience with the ntsb investigating accidents before and explain to our viewers in short-term why sequencing is important. >> today's development is important because it does not -- it's more consistent. if pilots put in this way point they were going to turn to, they knew in advance of the last communication they were going to turn. it was a premeditated act, turn off the course to beijing. if it was not premeditated, it do

rene and evan perez, thank you. that's not the only new information that we have to reveal about flight 370. now a second government is coming forward with radar data that supports the theory from malaysian authorities that the plane made a sharp and intentional turn off course. crews are scouring along two potential flight paths among 2.25 million square nautical miles which is an area about as big as the continental united states. let's bring in jim sciutto. jim, what are we hearing out of thailand today? >> this is radar data, as you say. you'll remember that earlier this flight path, this left turn off the original paddle up to beijing was first picked up by malaysian radar at three points along this path. we now learn that thai radar, covering an area like this, also picked up a blip from the plane going in this direction. first it picked it up when it was still malaysian air flight 370 and then it picked up another blip which they believe it to be the plane carrying it out here. combined with the information t

let's go straight to cnn's evan perez, who is breaking this news for us. you have talked to your sources, and what are they learning about this simulator that this guy had in his home? >> brooke, one of the things that they've been wondering is whether or not there was an indication of perhaps a practice run on the simulator of this westward turn that we've been showing on air. and what i'm told is the malaysians have shared this information with investigators from britain, from the u.s., from france who are on the ground, trying to decipher everything that they've got. and so far, they found no indication that any of this -- of any kind of practice run or anything to indicate that this was pre-planned. perhaps by the captain who is the one that had this flight simulator on his computer. they see his computers, looked at e-mail traffic, looked at everything that is on those computers and they've come up with absolutely nothing to indicate that there was anything nefarious being planned here. now, they've also gone through and checked any of the traffic dis

let's bring in evan perez and miles o'brien and cnn law enforcement analyst, former assistant fbi director, tom fuentes. miles, let's start with you. what do you make of this information that they are making out? >> a 270-degree turn right all the way down to left, it's very difficult, wolf, to come up with a scenario where that is some sort of a mechanical failure or malfunction. if a pilot was in a bad way, rapid decompression, fire, whatever you want to say, he or she would not take that long way around to gain that direction. it would be a sharp turn to the left. and so it's very difficult -- i've talked to a lot of pilots about this, it's very difficult to look at that diagram and not say that it was an intentional act of some kind. that jives with what nic robertson's sources have been telling him. the one thing i might quibble with on his sources, that could have very well have been flown by autopilot. it could have been flown automatically and in a gentle way that the passengers would have had no idea. >> tom, i know you have good sources over there in malaysia as well, that they a

we're finding out from sources who talked with my colleague evan perez some of the files were deleted more recently than originally disclosed by malaysian officials. so forensics experts and outside consults are working right now to find out what is in those deleted files but how they were deleted. that could be very telling if they were strategically deleted or scrubbed clean in a more sophisticated way than a routine way. on the other hand it could be very innocent, just routine deletions like something we would do on our computers and phones. >> if anything it tellsout fbi is finding things the malaysians could not. so maybe we'll get more thorough answers. pamela brown, appreciate that. >>> an international flotilla headed to the search site right now as we mentioned. ships from australia and china and malaysia and the u.k. but as we told you last night here, the first ship on the scene is that big one from norway. a massive cargo ship that rerouted. haakam svene, thanks for dialling us up again tonight. so how many times have you talked to the crew aboard that ship and how are th

i want to bring in evan perez and tom fuentes.ack to that in a moment, the whole pilot issue. but interpol released an interesting statement today really critical of the malaysians for not checking the database that interpol has. as we know, two passengers with stolen passports got on to that flight. the truth is, this is from the interpol press release, the truth is that in 2014 prior to the tragic disappearance of flight 370, malaysia's immigration department did not conduct a single check of passengers' passports against interpol's databases. what do you make of this? because pa malaysia claims that the computer system was too slow. >> that's an absurd claim. >> the malaysian claim? >> the united states queries that database 30 million -- sing ga p pore, 30 million times. in two-tenth of a second when the pass board is scanned, it goes through that database and it's scanned. that's a false claim. >> should we read anything into the fact that the interpol is releasing this statement? there was always suspicion about these irania

. >> david, about the deletions that the pilot has made, again, sources telling to cnn's evan perez that -- and pamela brown that there were more deletions later on than the malaysians had released but no reason to believe there's anything suspicious. >> right. the thing that bothers me a little bit is why did they think they know it and then they didn't? the malaysians have had a lot on their hands. i believe they're a little in over their heads on this. that's what gave me the indication that i know they're reaching out and getting more help. and quantico has the best facilities of anyone to look at that data. so it just indicates to me that they are in over their head a little bit. >> mary, you've been involved in this kind of thing before. one point you made several days ago is it's not just something that an eye -- an item was completed but if there was an attempt to overwrite it. >> right, if you took active steps to make it difficult to retrieve it, it would show that you were intending to cover your tracks, it would show an intent to hide. and at quantico in virginia, that's the

we're finding out from sources who talked with my colleague evan perez some of the files were deleted more recently than originally disclosed by malaysian officials. so forensics experts and outside consults are working right now to find out what is in those deleted files but how they were deleted. that could be very telling if they were strategically deleted or scrubbed clean in a more sophisticated way than a routine way. on the other hand it could be very innocent, just routine deletions like something we would do on our computers and phones. >> if anything it tellsout fbi is finding things the malaysians could not. so maybe we'll get more thorough answers. pamela brown, appreciate that. >>> an international flotilla headed to the search site right now as we mentioned. ships from australia and china and malaysia and the u.k. but as we told you last night here, the first ship on the scene is that big one from norway. a massive cargo ship that rerouted. haakam svene, thanks for dialling us up again tonight. so how many times have you talked to the crew aboard that ship and how are th

my colleague evan perez has been talking to his sources. they've told him there's no reason to believe there was nefarious intent. but of course they're still combing through the hard drive as we speak trying to obtain more information and more details about the deletions. pam, also this report by "the telegraph" newspaper with the communication between the cockpit and air traffic controller for the first 54 minutes or the flight, anything raising alarm bells or suspicion among people you've talked to? . of course because we're dealing with a missing plane everything is going to be under scrutiny and picked apart. there are parts of the purported transcript obtained by the telegraph newspaper some find interesting. for one the pilot repeated the altitude twice. also the pilot didn't repeat what air traffic control said at the very end which pilots are supposed to do. instead he signed off saying those infamous four words we've all heard, all right good night. pilots we've spoken to say informal conversational talk between the pilot and air

i want to bring in now as we talk about the investigation evan perez.e's in washington following the u.s. contribution to this vast search. i want to bring up one detail we have talked about for the last 4 -- 24 hours a bit. that's the idea that the pilot turned off the communication systems and then several minutes later gave a normal fine, thank you, good night as he was going to pass on to the next radar station but never did. how important is that clue to the investigation and what has followed since anyone, including the searches taking place in the pilots' homes today? >> well, i think one of the things that u.s. investigators have been looking at is the idea that, you know, the sequence of events. the turning off of the communication systems, the turning off of the transponder and turning the aircraft and then flying it for several hours. all those things they believe point to some deliberate actions. some deliberate actions that were happening inside the cockpit. so barring any other information, they have not found any indication of any links t

our justice reporter evan perez following that story for us today. evan, what's this all about?icly in a fight essentially with the malaysian authorities. the malaysian home minister this week went on the floor of parliament there and said that one reason why they did the malaysian authorities don't check against interpol's database of lost passports is that it might slow down processing of passengers, that it might take too long. and so interpol has now responded. and they've basically are saying that that's just not true. they say the checks take less than a second. and they say, you know, before this flight disappeared malaysian authorities had never even once checked against the 40 million entries on the interpol database. again, this is not usually an organization that speaks so bluntly. they're usually doing very diplomatic speakers, as you know. so it's very unusual for you to see them push back. the reason for that is they want countries to be checking against these databases. they say the united states, for instance, checks this database 230 million times a year. the uk

let's go to cnn's evan perez in washington. let's hone in on the batteries. what more do we know about that? >> they were looking at the situation from the day flight 370 disappeared because they saw on the manifest that was provided by malaysian authorities there was a shipment of lithium batteries. we don't know who the shipper was and where it was going. they don't believe anything nepharious was at issue. anything suspicious in the batteries being there. we know that was one of the first things they were concerned about because as you mentioned in 2010, there was a fire on a u.p.s. plane they believe was caused by the batteries that are more unstable than other batteries. >> we don't know how many. do we know if there restrictions on carrying the batteries? >> there. because of all these concerns and previous fires on the planes, they do have strict restrictions and international agencies that do this type of thing say you have to ship them and label them in particular ways. you have to wrap them in noncombustible material so that in case something happen

. >> cnn's justice reporter, evan perez, was at that news conference by attorney general holder.aking news for us having come through the deleted data. captain shaw had that homemade flight simulator at his home. it was confiscated. they found it had missing data. what can you tell us, evan? >> well, we can tell you that the malaysian authorities have turned over some of this information to the fbi and other investigators from other countries that are on the ground. we know that the fbi is going to take its own look at the hard drive from the pilot that was taken from his home. they are trying to figure out whether or not there is any indication of any pre-planning for this route, for this diversion from the route that we now know flight 370 took. so they are trying to figure out if there is anything that was perhaps premedicated on this. obviously, the focus is still on what happened in the cockpit. they don't know what, if anything, this indicates. we know that they have done other searches and they have found nothing that indicates any planning for a crime. they are still very
