there's too many questions still. >> that's where david gallo comes in, because you're able to look at the currents, the path of the plane that it took possibly under water, providing also crucial information. david soucie, david gallo, stand by with us for a moment, because the big question, what happens once they actually find the missing airliner, will it give families any sort of consolation? we'll examine what it takes to raise a plane from the bottom of the sea next.

fortunately, cnn david gallo is here. and david soucie author of malaysia flight 370, why it disappeared and only a matter of time before this happens again and cnn aviation correspondent richard quest. let me start with you, david gallo. we saw the sonar images that kyung showed us that may be part of the plane. i know you've taken a look at them. do you make anything of these? >> well i'll have to go with the explanation that they may be part of the plane. there's still something there. when you see the bright against the backyard that's hard reflecting off the bottom but i don't see big pieces. usually when you have something big, you have a shadow behind it. i don't see that nor a lot of definition. the one thing we're missing is a scale. we don't know how larmg the oblts are and it's going to be difficult if they don't have positions on each of those things for divers to find them especially in a given conditions. it's going to be tough. >> the bright spots though that could be -- it could be pieces of plane or junk o

david soucie and david gallo. we talked about the weather.sly, that is a problem in and of itself but there are also other problems with the search going on including the fact that this area is very well-trafficked and there are a lot of cargo ships in the waters. explain how that affects the search for the black boxes. >> one of the things we learned, especially from mh 370 is that when they thought they were listening to pings from the black box, they may have been hearing voice from their own shipper or maybe shark tagging. i took a quick glimpse of where the search is going on and counted dozens of cargo ships and tankers traversing through the area just commercial ships and that putting a lot of sound in the water making things more difficult, as does rough weather put sound in the water. so they really do need quiet as best as they can get it to be efficient at locating the black boxes. >> david soucie, obviously, the shallowness of the jabba sea certainly gave people confidence that the black boxes and the wreckage would be able to be

i'm wondering why we haven't heard more about bits of debris or debris fields. >> david gallo and lesre access to the family of the flight's pilot. we'll hear his daughter's tribute next. ou give some more. but sometimes you get. and so you take. tylenol® cold is strong enough for you while children's tylenol® is gentle enough for them. we give you relief from your cold and flu. you give them everything you've got. tylenol®. >>> friends and relatives of flight 8 a 501's pilot have been showing up at his home and supporting the family. gary tuchman was allowed into to the pilot's home. >> this is what it looks like in the home of captain airasia flight 38501. this is 24-year-old daughter angela and wide widya. this is his father this his mother and a house full of foomly and friends, a house so full that more people are outside in front of the home as well as out in the street. this the indonesian name for the traditional visit made when there's a death of a family. angela still talks in the present tense about a father she adores. >> he is kind, wise and humorous. he's easygoing. he's

. >>> few people know the challenges of conducting this kind of search better than david gallo. cnn analyst and he joins us now with cnn safety analysis david susi, flight 370, why it disappeared and it's only a matter of time before it happens again. in the monsoon season in this area, i think, goes until april. >> yes. they'll be looking for any opportunity they can to make whatever searches they can. they know they're in the right area. that is the only piece of encouraging news. the reports of sonar, reuters reporting sonar has located the aft section or tail section of the plane. it's just a question now of managing to get down and actually see what is real and what is not. >> david susi, the report from one ship -- it is just from one ship, that they may have located the tail of the plane, in many ways that is the key to this search. >> it could very well be. however, in this aircraft, it's not the same as the 777 as to where they're both located in the far back tail. these are separated, one in the back of the tail but the other is forward of the restrooms in that aircraft

david gallo, we were talking about this probable area, the new probable area.2,000 square miles. that's still a considerable amount of area to be searching. how long do you think that will take? >> well it would take -- if it was deepwater, it would take a month or more to do that area and do it well to be sure you didn't miss anything. depends on how they're looking. if they're using sonar with multiple vehicles, may go fairly quickly. in addition to that use a pinger locater to look for the pingers. but they have to have cooperative weather. right now, if they can't get more than a day or so at a time it's going to take an awful long time. >> and, tom, that's really one of the issues here with the weather. we're talking winds at sometimes of 30 miles per hour. and that really threatens some of the aerial capabilities here. how important is it to have those aerial capabilities? >> it's very important because they need to follow the debris if they can back to where the crash site is kind of like following the breadcrumbs. the problem here is that the currents i

joining me now cnn aviation analyst miles o'brien, david gallo, director of special projects for woodsinstitution in massachusetts and peter goelz, former director of the ntsb. good morning, gentlemen. >> good morning. >> good morning. >> david, muddy water, zero visibility in the java sea. what needs to happen to make the search easier or more effective? >> they need a break, decent weather at the surface to get in and out of the water safely and they need to see what they're doing at the bottom and they can't and it's dangerous to be in the water diving with the wreckage around if it is breckage. they haven't identified a single piece of wreckage on the bottom of the ocean yet. >> miles, when the water is posing this many problems how can maybe an air search be effective? >> i don't think an air search is going to help out much at all, given this weather situation. this is the very weather that we think is somehow linked to what brought the aircraft down. at this time of year in that part of the world, this is unfortunately what you get most days. if this happened six months from now

. >> this of course is david gallos' specialty. flight 447 and cnn analyst with us as well cnn aviation analyst and private pilot miles o'brien. indonesian authorities are trying to confirm they found what they think is the tail of the plane. do we know exactly what is contained there, in terms of the black box? is it the flight data recorder? what would be there? >> well you know it depends on how much of the tail they got. on this version of the airbus 320, the black boxes are up a little bit further in the aircraft. it depends how much of that tail section they got. and hopefully, they did get a part of the tail section. even that part has not been confirmed yet, anderson. >> miles, there are thousands of this kind of airplane in use, the airbus a320. the idea this crash could have been because of a flaw is pretty scary, considering how many people are flying on these planes every single day. it make it is harder to understand why efforts to install something like live streaming track rg moving so slowly. >> a lot of resistance

we want to bring in david gallo cnn analyst and director of special projects for woods hole oceanographic constitution and david soucie safety analyst and former faa safety inspector, the author of book "malaysian airline flight 370: why it disappear and why it's only a matter of time until it happens again." david soucie we have one of the so-called black boxes, obviously not the one that they're looking for. but a version of it. it's interesting because i've reported on dozens of plane crashes, but i've never actually seen one of these black boxes before in real life. it's much heavier than i ever imagine with all the equipment inside it. how confident are you that the black boxes in the airasia flight at the bottom of the sea are still in the tail section. >> the cockpit voice recorder is further forward, it depends where the tail broke off as to whether they're together or not. typically like on the 777, the boxes are co-located. in this case one is a little more forward than the other. so depending where it broke off it could be a very very difficult task trying to find both boxes, w

. >> we have david gallo of the oceanographic institution us with now. u know, the poor visibility, strong currents and the java sea. weather is better today but not great. it is causing so much of a problem to find what is left of this plane. how much more difficult does it become as the days go on and on to find maybe the smaller pieces of this plane? >> sure. for the families involved, it's painfully difficult. but you know, even out there as part of the team, you feel that pressure. you want to be able to bring some closure to the families even though it's not much. it does. the teams get out of rhythm. you just can't start and stop without disrupting. you want to be going 24/7 every single day. this very disruptive so far. >> our gary tuchman, he's there in surabaya. the indonesian government says that aids concluded there is a strong possibility the engine iced due to the weather there. and the engine stalled. and then the plane crashed. based on the evidence that black box has not been found. what we know and what has been found thus far, do you be

joining us now, cnn analyst david gallo and colonel ken christensen, aviation consultant. pieces of metal, significant pieces of metal aboard the "uss fort worth" right now, one of the u.s. warships searching the area. how long will it take for them to determine whether these two pieces of metal are actually from the aircraft? >> well again, wolf, it's going to take getting eyes on that wreckage. until tlahey get a robot or camera system or a diver in the water, not going to happen. >> ken, the weather has gotten a little bit better, we're told. but the current under water is very very strong r 2 to 4 knots, they say. how hard is this making this mission that's under way right now? >> i think because it's a concentrated effort now in a different area than you were looking initially, they're still searching from the air and still searching the water. so that coordination and all those assets are there expending time and monies. and that makes it difficult because the divers underneath the water are struggling so hard. so that coordinated effort can also be hindered by just

david gallo is very familiar with these waters and expressed concern that there is a lot of debris on the bottom of this ocean. so i don't want to get anybody's hopes up right now about the fact that they have found the aircraft because that is simply not true. they have just found some metal objects of which there are still remnants of war fought down there. ships, planes. there is a lot of debris down there that may not be this aircraft. >> allen, do you agree with that? are we possibly looking at debris from something random? >> well some of the things appear to be from the -- obviously the passengers are. i should also say that i -- one of the other first investigations i did for nsb was a 727 that crashed into the pensacola bay. and that aircraft hit at 11 feet a minute a very high sink rate. but it was largely intact. it looks if these pieces actually came from the aircraft and there are indications at least with the floating debris i think david would probably agree the life rafts and so on are probably from the aircraft. but that boeing did not break up. so this tells me that

david gallo, the weather getting in the way of the search.h waves and winds really making things very difficult. >> sometimes you know you have to shut down operations and it's bad for the teams that want to get into a rhythm of working day and night to get this done. i know they're feeling the pressures to do it also for the families what a horrific thing to have to go through. sometimes the best planned expeditions, you have to stop everything. for the sake of safety and for being able to work properly. >> do you still see progress though here as they close and make the search area smaller and small centre they do have the tow pinger locater in the water? >> it's gotten smaller over time. it's about half of what we had to look for for air france 447 that was 5,000 square miles. for the tpl, the tow pinger locater, that's an awful lot of commercial traffic in the area and i'm assuming the team knows enough to be able to clear some of that out so they can listen appropriately. >> what you're saying is despite the fact that we say these are sh

you add it all together along with this upswell and you have a wild ride. >> david gallo, back to the search, it's murky down there. visibility some people say there's zero visibility down there. what do they need based on your experience that they don't have right now? >> ten feet would be great. the thing, wolf it's one thing to be able to identify these pieces and make sure they're bits of the plane. but if they have to try to lift them or penetrate into a fuselage to pull out bodies or the black boxes, i don't think they're going to do that. that's an incredibly dangerous situation to be in given the currents and what's floating around in the water. >> peter, do you think all of these a320s flying around need to be 23479ed because of what happened? there was another incident over the weekend, another plane had loud noise, fortunately nothing happened. but should there be an inspection going on? >> no, it's premature. it's a workhorse, it has a good record. i don't think there's any reason to issue any kind of emergency inspection order because we don't know what happened yet. >> a

. >> it was indicated by david gallo that there's a lot of shipping traffic so a lot of noise for those devices. >> towed ping locators as we mentioned for those of you that are sort of new to this we've learned a lot, certainly with mh-370. you've both taught us a lot. so they have the side scan sonars they also have these towedtow ed ping locators and it's important to talk about the acoustics of the ocean. it may not be very deep only 100 feet comparatively to some other portions of the ocean. this is fairly shallow. but there's still acoustic noise there that could be affecting search efforts. >> and the reason it was so sensitive to acoustic noise during the 370 search is because of the fact that we were kind of using it for what it's not to be designed for. it's not designed to locate the aircraft. it's designed to locate the box within the aircraft after it's under the water. so it's more of a approximate using the hydro phones to find it locally because it can be under silt it can be under the aircraft. it's difficult to find. it's not like it's sitting there on a shelf somewher

david gallo, les abend, thanks for being with us. of the doomed flight's pilot. how the family is coping with all this uncertainty and grief. more of our continuing coverage of the clash of airasia flight 8501 after this. >>> good morning everyone. welcome back to "new day." i'm john berman. i want to get to the latest developments in the search for airasia flight 8501. crews were able to get back out on the water thanks to a break in the bad weather but they had to retreat again as rough conditions returned. nightfall arriving. nine bodies have now been recovered, 153 souls remain missing. the first victim has been positively identified two more bodies are being flown back to land at this moment. right now questions are emerging about what radar data shows about the flight's final moments, and a big change in altitude that could have led to a stall ultimately sending the plane plummeting into the ja is asea. we're covering the story from every angle beginning with paula hancocks live from born know where the recovered bodies are bei

david gallo is a director of special problems at the woods hole oceanographic institution, he helped lead the search for air france flight 447. david, i want to start with you, the searchers have had quite a time trying to get into the ocean to look for victims and any debris. what are they confronting? what are the conditions that's making this so tough? >> i'm sure they're extremely frustrated as we are sitting on the sidelines, watching. it must be a heavy current. they can't hold position and when they get in the water they've got zero visibility. and that adds up to a very dangerous situation when you're working around wreckage on the bottom. >> mary, without hearing the pinging of the black boxes, since they haven't been able to how do they know they're looking in the right place? >> well they only can do that they can only know where to look by where the wreckage has been found and trying to trace the wreckage back based on currents and current time tables and the flow of the wreckage and the bodies in the ocean. it's kind of basically backtracking upstream. and then with the s

let's bring in mary schiavo and we have david gallo at the woods hall institute. he was a leader of the search for air france flight 447. great to see both of you. mary let's start with the most pressing question. of what caused this crash. what is the latest thinking? >> the latest thinking out of indonesia and it is just one of several theories. they believe it is icing within the engine. they call it chunks of ice forming within the engines and perhaps breaking free and injuring the blades and causing loss of the engine. i think icing is prevalent, but icing on the clouds and on the plane. the plane is capable of doing. more than likely it would probably be hail and really the products of the storm. that is the latest thinking. ice in the engines, on the plane or ingested as hail. >> david, that is a trouble theory. it is winter in the united states. thousands of planes fly every day. how can we not be dealing with the same level of icing that brought down that plane? >> well, many as you said thousands of planes flying every day and routinely very safe. it is
