also joining us steven wallace, a former faa director of accident investigation. jim hall, what do you make of these images? some are suggesting they may not necessarily be any debris from that airliner. others are saying it could be a very significant moment. what do you think? >> well, it appears to me, wolf, just from the images i've seen on television, that there's a strong possibility that it could be flight 360. and my thoughts, of course, first go to the families because they will not have peace of mind until this wreckage is found. >> flight 370, to be precise. >> 370 -- i apologize. >> that's all right. we don't know and some are nervous, some are cautious about this. steven wallace, you've taken a look at the size of these three big chunks that china has seen on its satellite images. your conclusion? >> i heard your analyst say they estimate the dimensions of the debris about 40 by 70 feet. well, when an airplane goes into the water, whether it impacts intact or breaks up at high altitude, what floats are lighter weight typically interior components. maj

bring in cnn aviation analysis and former director of the faa office of accident investigation steven wallaceews out that press conference, word that the pilot's flight simulator had deleted data and they're working to restore it. does it raise any red flags to you? >> well, not particularly, just for a couple reasons. one is many airline pilots are obsessed with flying. they just love flying. this captain was putting his simulator on facebook. so that's just sort of, i would call, it normy nerdy pilot behavior. that doesn't raise a flag to me. he had a pretty elaborate simulator for this home. to plan a flight to some destination other than the intended destination of beijing, it's not difficult. it wouldn't really take a lot of practice at all. if he had decided to divert it. also, you know, the fact that the data was deleted. i mean, i hope this is some valuable evidence. but, you know, it's like deleting an e-mail. >> that's right. how much do we all delete stuff in all of our various electronic devices. it may not be significant. but again a new piece of information that we learned this

i'm joined by steven wallace, accident investigation for the faa. good to see you, steve. let me start with the lithium battery story that we've gotten now. the question that pops into my mind is why are we getting this kind of information this long after that plane disappeared? >> there's a consistent pattern with all of this evidence. there's doubts about its quality and it keeps arriving kind of slowly in dribs and drabs and to say lithium batteries is kind of like saying stolen passports. >> right. >> so red flags start to go up. of course, there was a terrible ups cargo plane fire attributed to lithium batteries. but there are very, very strict rules about how they need to be packaged and transported. of course, if there was a fire in the cargo hold, this plane has the latest detection and suppression. the crew would have been making emergency calls. >> right. but this indicates that after a derth of information from the malaysian government for so long, someone looked at the americans and thought, oh, lithium batteries and that takes on a life of its own. >> well, i

let's dig deeper with steven wallace, former director of the faa's accident investigation and our cnn law enforcement analyst, tom fuentes, former assistant fbi director. steven, now that the ntsb, steven would lasso owe now that the ntsb apparently involved, why is it difficult if the malaysian air force says it spotted this plane going across malaysia, no transponder, but they have radar, why is it so hard to interpret that radar? >> well, i'm glad to hear just now that the u.s. experts and ntsb has some very first-rate radar experts and faa experts as well looking at that data. without the transponder on, you're just looking at the bounce off the skin of the airplane. this is basically radar that is designed to help you see somebody who doesn't want you to see them. like an enemy. so that primary radar is just a sort of -- can be kind of a fuzzy blip. so -- and whereas with the normal transponder, you're going to have a data block as to where the airplane is, the speed and altitude and all that. >> so it's -- so they think the malaysia air force, this was the plane, the 777, flying

let's bring in two experts, steven wallace is former director of the faa's office of accident investigation. and cnn law enforcement analyst tom fuentes, former fbi director. steven, any of these scenarios make more sense to you? >> wolf, i heard an expert say, you know, it's time to call an investigation of the investigation. and i agree with that. >> the malaysian government's investigation? >> yes. the entire investigation. you know, until you know where the accident occurred, you're not sure which country's in charge. but absent that international waters, the country of registry malaysia is in charge. as near as i can tell, this accident investigation hasn't even started. you convene the parties together, you designate groups to focus on different areas. this is the normal iko process. now, we seem to have a new theory every day. two days ago we were focused on the radar data. >> malaysian air force. >> right. people have questioned that. experts i've talked to say there's a lot of reasons that that doesn't look too reliable. but it was worth looking at. yesterday we had this floating p

let's bring in former director of the faa's office of accident investigation, steven wallace. he's also a cnn aviation analyst. first of all, thanks so much for joining us. i'm hoping you can let us know what's next in this process. so, there are planes headed that way, ships headed that way to identify the debris. after that debris is identified, what's next? >> well, i think, rosa, you just outlined the next steps, send planes and achieve some greater level of precision as to what we're looking at. i have to say that when i walked into cnn this morning and immediately looked up on the screen and saw that this object, it was estimated to be 74 feet long, i immediately flashed back to the chinese satellite photos we saw so early on in this investigation, which most of us would quickly dismiss the likelihood that that could be a part of the aircraft simply because, typically, lighter, interior components float. now, i just heard, and i don't disagree, if this plane had run out of fuel, this wing could be very light and might float for some period of time. clearly, what's next i

let's bring in jim sciutto and steven wallace, safety consultant and former direct for of accident investigationand cnn law enforcement analyst, tom fuentes. steven, what about that shadowing theory? is that at all realistic? >> i think not. it's -- of course, with the transponder off, the other plane may not detect it but that's about as far out there as anything we've heard in the last ten days. >> i have to agree with steven. if the transponder is off, it would still get some blip. the other thing that happened is air traffic control would have asked that aircraft if they hear any emergency beacons going off. >> what if it was flying at 35,000 feet, the normal route, let's say singapore airlines, flying from the far east to middle east, going into an area, would those countries necessarily have paid attention to a huge 777 like this? >> it would have been off its track. so air traffic control would have alerted somebody and said, we're missing an airplane. when the airplane goes off of its prescribed track, you have to tell somebody about that and if the airplane did go off, air traffic contr

. >> for more on this partial ping and what could have been the final minutes of this flight, steven wallace. keith, if i could begin with you. we're getting these pings, it seems every week, new satellite information. this one is interesting because it comes -- came eight minutes after what we thought was the last ping at 8:11 a.m. how do you read this and what could it mean? >> from what we understand, when the ground station doesn't hear from the aircraft, it's going to create the handshake. we get this every hour. >> when this one came, not at the very hourly point, it came eight hours after the previous report. >> that's clearly why this jumps out of the data. >> what would that mean? why would a plane send that ping outside of reports? >> that's right where we are, the question of the day, is this when it hits the water? is this what causes some partial burst of information as the electron nicks in the aircraft are inundated with water? whatever information data burst is available, that's what they are looking at. >> this could be something that might send out a burst, not on its sched

steven wallace is former director to for the faa's office of accident investigation, also a cnn aviationlyst. we are rejoined by chad sweet and richard aboulafia. thank you all for being here. we're going to solve the thing right now. right? so they have widened is is search area, something that is almost impossible it seems to me just in terms of how big it is. how do they winnow down, colleen, where you look in this gigantic area? >> something we were talking about earlier is a way of using negative information to contain the search area. by that i mean if there's a radar or something else that should have detected the aircraft in a certain area and did not, you can say the aircraft never made it to that area. we were talking about the radars on the coast, india, pakistan, some of those countries up there in that northern arc, if we could get them to look at their radar tapes and see that there was no target when the aircraft should have gone through there then that would make us focus more on the water or down south. >> so you could rule out, look, there's no way this plane -- it's be

steven wallace is former director of the faa's office of investigation. >> airplanes can go off course. they can go offcourse because a pilot deliberately flies them off course. we have the ethiopian pilot recently fly through geneva. >> also of interest, the plane's last communication occurred right at the transition between malaysian and vietnamese air space which could add to the confusion in finding the plane. >> the point of maximum confusion where malaysia thinks everything is fine, it suddenly disappears. and that gives it the maximum opportunity to fly in any particular direction unmonitored. >> reporter: tonight malaysian authorities are still searching on both sides of the malay peninsula. they've asked american authorities to help interpret all key data. one key question is what other data streams was the plane sending out after its transponder stopped? rolls royce engines like the ones on the boeing 777 have the capability to send out data. rolls royce won't say if they did on this flight. >> you talk about conflicting information. so the state of play now is you have the c
