welcome to you also david soucie. this component number that they spotted on this wing matches a boeing 777. the question is how do they take that number and this piece of a plane and be able to definitively say, this is mh-370? >> that number could be a number of things. but one of them could be just an inspector's stamp. and the inspector stamps are all registered. so we know which inspector inspected which part on which day. that can be tracked back. the other thing it could be is other manufacturers make subparts or subassemblies of that entire portion of the wing. those, again, are also tracked and then they go into an assembly which is the entire piece and that has a part number and that part number starts with a 113 w and then 611 or something afterwards. this will tell them that it is indeed from 777. it may not tell them which serial number until they see the 113 number. >> are we talking days here? could it be that quick? >> well i'm quite frankly, that they are shipping it back for this kind of inspection.

david soucie wrote this book "malaysian airlines flight 370." david, now, even boeing is saying that it has a high level of confidence that the pete of debris is their part. what else needs to be done for someone to say, yes, this is it. >> these are scientific investigations. itis not saying yes, i have seen this part number and that's what it is. we have to know what it is, the process for how to report it and the process for how it is documents. that takes time. even after they get on the site, i wouldn't expect them to say, oh tharks's it. it will take time to get it done so there's no question. the surviving family members deserve that. it needs to be perfect. there's no room for error on this like there was early on in the investigation. >> that is why they are not rushing to answer the question. >> les, so many theories about what happened to this airplane. which of the theories might this piece of debris, if it did come from flight 370, could this rule out? >> anything is speculative at this point. one thing is the conspiracy theory the a

with me david soucie. he's a former safety inspector. welcome to both of you. ith you. suicideal pilots are not unheard of. of course you remember the german wings flight. that pilot left behind ample evidence and they eventually found the black boxes. now we're looking at this little piece of the wing. could that at least solve part of the mystery? >> as far as whether it was suicide or intentional, this is not going answer that question. we're still looking for the black boxes which is likely at the bottom of the ocean back in the search year. this is just an indicator. i think it's profound for the families of these people on woerd e board, because they might be able to put away those thought that is thes that thatthe aircraft has landed somewhere. i don't think there's enough evidence from these parts to tell us whether it's a terrorist act or suicide. >> some people because that piece of the plane is intact it rules out an explosion, right? and other people saying because that part of the plane is intact it sort of proves the pilot could have landed a slow

. >> i was just about to say, david soucie plug your book. >> "why planes crash" go. >> the book is mh370, why it disappeared and why it will happen again. it will happen again. how much time do you want to give this miles, before it happens again? we have been 17 months. how much time is there between major airline can a cattastrophes? i don't think so nor does my analysis think so. >> both of you -- i submit to you, i have not heard your plausible explanation for how a mechanical failure would lead to what we see there. >> pause. >> it's an extensive analysis and it's there. >> pause for one second. david, answer me this. with all of these theories -- we have seen them all. we have discussed them all. we're discussing them here. is there anything we're going to see wash up in the ocean, like we have seen this piece of debris that's going to get us these answers or does it all still come back to needing that flight data recorder? >> yes, there's a very important piece and that's the ray dome of the aircraft the front of the aircraft, which is also honey comb similar in texture and size a

david soucie let's talk the suitcase. by the flaperon was a suitcase.ts way to france today, as well to be looked at by investigators. we don't know if it will turn out to be anything but what can a suitcase tell you? >> typically you find that -- look at the size difference. look at the buoyancy difference. look how different they are. to think they both traveled 2600 miles with different characteristics from the flow the projection out of the water, i find it difficult to believe and the probabilityies are low that the suitcase is from the same aircraft. >> if the flaperon was from 370. there's more debris that will turn up in some places. very likely on reunion island or nearby. do they need to put planes in the air or scour the coastline on reunion, madagascar and east africa to check? >> some reports said they had helicopters out there looking for debris. it's not been sub stan shuated yesterday. the one i think happened is that piece came off the airplane as it was in a steep tran sonic mode. that would tear pieces off the airplane because you are

miles o'brien, our aviation correspondent richard quest, also joining us now cnn safety analyst david souciee writer irving. from what we know right now what's your conclusion? is it too early to reach a final conclusion? there's still a lot of investigation that needs to go on. but based on what you know and you've studied this closely, was this plane gone as a result of a mechanical problem or some deliberate act by someone? >> i think there's a lot of over there are controversy spreading around all those theorys. we should remind ourselves, well of, that the problems of searching for a lost plane over water haven't changed since the days of amelia earhart. the problems that you've just discussed very well about how difficult it is to find small pieces floating on the top of the ocean apply now to this tragedy as they did then. and the scandal behind that, of course, is that none of this needed to be necessary. if there'd been proper tracking system available on this plane you wouldn't have spent these enormous amounts of money and enormous amounts of time searching for tiny pieces in a ve
