Now since the boeing 777 with 239 on board vanished from that flight from kuala lumpur to beijing. Tonight well hear from a naval commander involved in the search, take you aboard the p 8 poseidon which spotted some of the debris today. And well demonstrate right here on the studio the technology of those socalled black boxes use to lead searchers to them. First the latest from our kyung lah at search headquarters just outside perth. Kyung . Reporter anderson, we can hear the turboprops of the military planes starting up here at the air base. We dont have the official schedule of what the search is going to look like, but we know that they are going to be heading to the new search area which has already revealed some intriguing clues. Five planes, including this american p 8 poseidon, cnn was aboard, spotted possible debris floating in a new search area today. Raising hopes search crews are closer to what could be the final resting place of Malaysian Airlines flight 370 the. The objects are very distinctive and definitely man made objects. Reporter among the things spotted, white objects, orange rope and a blue bag. One of the other debris satellite images picked up earlier in the week, hundreds of miles away from the new search site . It depends on who you ask. Australian authorities now say after further analysis, they cant be from the plane. But the malaysians arent as quick to discount the possibility. Because of ocean drift, this new search area could still be consistent with the potential objects identified by various satellite images over the past week. Reporter the new search area was determined after information gathered from radar and satellite about the planes speed and fuel usage led investigators to believe it traveled faster, and therefore not as far as originally thought. There are some up sides to the new search zone compared to the old one. Its closer to land, which gives planes more time for surveillance onsite. The waters arent as deep. And the weather, which suspended searches for two days over the past week, isnt as extreme. But there are down sides, too. The ocean floor is more rugged in some places, which could hinder locating the flight data recorder, and therefore the actual wreckage. Still, officials remain upbeat. The search area has moved out of the roaring 40s. We will see what that does in terms of satellite rit when. Reporter leaving plenty for ships to comb through once they reach the area. Kyung, you were aboard the p 8 poseidon. Whats that like on board the aircraft . Reporter well, it was amazing. This moment when they thought that they might have discovered some debris, some possible debris. The finding that item that might give these families an answer. We felt the power of this amazing military vehicle. We were skimming, almost skimming the surface of the sea. But what really was remarkable was the sense of hope among all of the crew members. There were nine people aboard. And there was this feeling that maybe this was the answer. And you really felt it, anderson, that the people who are going up in these search planes, they want to bring it back. They want to end this. No doubt about that. Kyung, thanks very much. Want to bring in commander William Marks of the u. S. Navys seventh fleet taking part in the search. Commander, good to have you on the program tonight. The weather conditions do seem to be much better today. Hows the search gone so far in this new area . Thoroughly much better today. Today is our new day here. Its in the morning. So were getting our assignments via the air tasking order from the australians. What a great report i just heard. A tough act to follow there with the emotions and the feeling of hope with the air crew. I have flown on the poseidon. Such an amazing aircraft. In terms of the search capability and the technology on there. But i do want to mention this area is much better for the search effort. One, its just so much closer. So instead of spending twothirds of the flight time just in transit, now you can get to the search area much more quickly. Yesterday we had over four hours of search time compared to three or three and a half previously. So more search time in the area. Better weather. Previously some of the flights had to be canceled because of the weather. Right. After that old search area. Now we saw ceilings even in bad weather a little bit yesterday, the ceilings were still 2 or 3,000 feet. So still much Better Weather there. Then the third thing go ahead. Go ahead, commander. Well, the our oceanographers and the navy as you could expect has some of the best oceanographers in the world. Were working very closely with some of the people at the base center. And the critical part, if we do find debris, is this reverse plot. The reverse engineering of of the wind and sea state and current to get the starting point. Thats really waste critical. Finding the debris in and of itself is okay. But its working backwards from that starting point in this area will be hopefully much better for that. I asked you yesterday based on some questions that wed received about bringing in an aircraft carrier, that planes could take off from. Obviously the poseidons are based on land, dont fly off ships. But what about bringing if debris is starting to be found in this new search area, has any thought been given to bringing in any platforms that helicopters could go off of, any u. S. Naval vessels, helicopters or other planes could go off of to try to aid in the search once an area is found . Well, i should mention, this is a coordinated international effort. And everything we have done has been by request. So at first even when we sent our first ship in and the first helicopters, that was all by request of the malaysian government. So the u. S. Navy, part of our role is to support all the nations in this region. If were requested well certainly look at those options. But really at this time, yes. Thats true. Commander marks, i appreciate your time. I appreciate all your efforts. Thank you. Want to bring in our panel thats going to be with us throughout the evening. David soucie, cnn safety analyst, author of why planes crash. Cnn aviation correspondent richard quest, meteorologist chad myers, former department of tp transportation Inspector General mary schiavo. Private pilot miles obrien. David soucie, the fact that basically i think five or six out of the ten planes searching has spotted some items in the water in this new search area, what does that tell you . Makes me cautiously optimistic. Hopefully that ship the ship being out there is more encouraging. At that point theyll be able to see what it truly is. Richard, you think this debris area does seem more promising . Yes. Because youre looking for not just one piece, youre looking for several pieces. And when you and i were talking la last night, even while the australians were announcing the change in the zone, they said four planes were already overhead and five of them have found objects today. Now, we thought that the thai 300 and japan ten pieces. So youre right to have optimism. Or youre justified in having optimism provided youre in the right place. I know that sounds somewhat obvious. The fact that these were spotted biplanes as opposed to satellites which take days to reposition which take days to analyze, that certainly in that old search area there werent any objects spotted biplanes. We saw them by satellites. There were two i think spotted biplanes on one day, a green and orange item. But nothing more than that. The fact weve seen so much spotted, its still a vast area. Its still got a long way to go. But they are quite confident. If you liston what the new Zealand Force has said in that report, they are quite confident that at least theyre getting closer. And miles, certainly its an easier search area for as you heard from commander marks in terms of distance and time theyre able to spend over that area. Yeah. The closer you are, the more time that the aircraft can spend on station actually flying grids and doing their work. So thats a good thing. Its also apparently perhaps because of its proximity to land it appears that the sea state there is a little bit better. So all those things are good. And we should be reasonably optimistic. But we have been down several dark alleys before. Chad, lets talk about that sea scape. Do we know much about the currents in this region . I know its a very deep area just like the previous search area was. But there was some question last night were they looking for an entry point or debris. Obviously theyre looking for debris. But any sense of how long debris would be floating around in this area for . Well, this is the most opportune place that this search could happen if in fact they do find something. Because there is literally a black hole of very little motion in this area. We were talking about a half a mile to a mile per hour in the areas down south in the roaring 40s. These are now on up into the 35degree latitude, 40degree latitude here. And things dont go very fast. They dont go very far. Are those currents, those neon color things . Absolutely live currents spinning in each direction. I can get it a little bit closer. Might be able to see it a little bit better what were seeing here these streamlines. Theyll show us what little pieces of debris, what little plankton would be doing here in the ocean, going this way and this way and this way. All part of that gyre we talked about last week where if you think about the indian ocean, there is a vast area here where the water, the current, generally goes to the west, the south, to the east and to the north. Right through the middle is kind of the garbage pile ithink thats why we have found so much stuff, because this stuff just sits there and spins around for years and years and years. Mary, last night when we talked there was a sense among everyone that was sort of going back to square one. Though that certainly seems to have changed just in the last 12 hours as a lot of five different planes have spotted objects. Well, thats right. And i dont look at it so much as going back to square one as being very open and receptive and accepting of new information. They said they had conferred with the ntsb, the faa, boeing and others. And they found better data, better coordinates. And thats really what a good investigation has to do. If your data is bad you have to be willing to throw it out along with all your preconceived notions, particularly if youve got any piece of data you were hanging on to that was your anchor you have to be willing to throw that out. I think that actually is signs of a healthy investigation. They said hey we have better data. Its time to change our coordinates. Again, miles, were getting pictures from aircraft. We saw that rectangular object that was spotted. Does that look like something to you . Well, weve been talking about it all day of course. One thing i dont know the scale, is that the size of a Lottery Ticket or a refrigerator door . Im not sure. Somebody tweeted at me and said is that a lavatory door from the airplane . Im not sure it would float but potentially. But generally speaking, rectangular objects we dont associate with the outer skin of an aircraft which will be curved and swept back and aerodynamic. This is something you want to go pick up and see what it is. David soucie, do you see anything there . The only thing potentially again like miles said, without scale its virtually impossible to determine what it is. It could be a landing gear door, square flat similar to that. But it would also have as he mentioned aerodynamics. Other pieces of plane as well. Absolutely. The idea, how much time has been lost here . I dont want to sound critical because everybodys been trying to do their best obviously with very limited information. But have the last five days, six days, searching in that other been a waste . I dont think its a waste. As mary pointed out, it shows to me theres a healthy thing going none this investigation, the ability to look at what youve done, admit that hey, maybe we have some better information now. Lets accept that. Lets give up on what we were doing and move forward. I think that is a healthy sign of this investigation. In every investigation you have setbacks, you have advances. Its just a matter of trying to balance those out, stay calm about it and really evaluate each piece of data as it comes in. It seems richarded fact its planes spotting this theyre going to have a much better opportunity to actually gate shget a ship there in time rather than a 4dayold satellite image. No question. Probably this weekend if theyve already spotted objects at least getting some ships to those objects. The plane spots it, drops a buoy with a transmitter. Ship arrives. If its still there, picks it up. Im simplifying it greatly. But we were listening earlier to the commander talking about the process. Whats going to be interesting now tonight, the australians have made it clear this is a little bit of politics, a little bit of geopolitical strategy here the australians have made it clear that any debris or any objects picked up must be returned to western australia. So any other ships, if the chinese pick something up, any of the other ships, u. S. Picks something up, they have been tasked by malaysia, they have primacy. It must be returned to western australia. And then the process of how that will be announced will be sorted through. A lot to watch for no doubt even tonight and throughout the weekend. Weve got a lot more developments to get to in this hour. Follow me on twitt twitter andersoncooper. Ac360. I want to dig deeper on whether the old and new search areas could both contain some sort of wreckage of an aircraft. Also those sonar pingers that will lead the investigators to the flights data recorder will actually sound like. We have a demonstration how they work, what they sound like when they hit the water. Well be right back. Discover card. I missed a payment. Aw, shoot. Shoot this is bad. No were good this is your first time missing a payment. And youve got the it card, so we wont hike up your apr for paying late. Thats great it is great thank you. At discover, we treat you like youd treat you. Get the it card with late payment forgiveness. But i didnt always watch out for myself. With so much noise about health care, i tuned it all out. With unitedhealthcare, i get information that matters. My individual health profile, not random statistics. They even reward me for addressing my health risks. So im doing fine. But shes still gonna give me a heart attack. Innovations that work for you. Thats health in numbers. Unitedhealthcare. Bentastefree andr, dissolves completely.

Awesome awesome awesome awesome awesome awesome awesome all awesome i love logistics. Ships zeroing in on the new search area after five out of ten aircraft spot objects floating in the water there. This raises all the normal questions weve been asking about every sighting. Is it real, can it be covered and physically identified as coming from the missing 777. Another question as well we touched on at the top of the program, do these new sightings totally invalidate all those other ones back in the old search area some 700 miles away . Australian authorities seem to say so last night. Malaysian authorities seem to have a different explanation. Could the old sighting somehow connect up with these latest discoveries . Malaysians raise that idea. 360s tom foreman joins us with more. Tom, this new debris found in the new search area, youve done some analysis. Is it possible its part of the same debris from the old search area . Reporter well, lets take a look at the possibilities here. Because the numbers dont look very good. If you take a look at the overall picture here, and you think about where the satellite debris was that we were talk about yesterday, thats down here, this very turbulent area if you look at all the currents going here. The new debris is up there. About 700 miles away. A normal drift rate might be about a half mile per hour. That doesnt get you there in six days. A hydra freight might be two, three, four Miles Per Hour, not consistent all the way up there. That doesnt get you there. Really you need some sustained 4 to 5mileperhour drift. Bottom line is no. In all likelihood, what theyre finding up there has nothing to do with what they found down here in terms of it being the same thing. Could they be from the same source . Yeah, they could. But thats a whole different question, anderson. Clearly they dont put much import into the debris that they were looking at before, the objects, whatever it was they were looking at before. Theyve now devoted all resources to this new search area. Not even calling it debris anymore what they saw before. Even if they determined that these new things that they picked up in the new search area that they picked up in some photographs is part of the plane that, doesnt really tell them where the rest of plane is, correct . Reporter no. It actually doesnt help them at all, in part because of time and space. There has been a lot of time since this thing disappeared, and were talking about a lot of space. Let me bring it in here and talk about this. If you were to grid off this area as they do for searches like this, youre talking about narrowing this down. Theyve been trying to tighten it down as much as they can. Were talking about narrowing this down really to a sing el point out there in a quite immense area. And once youve narrowed it down to that single point and you think about all the possibilities of where this could have come from, then you have a real problem. Because you have 20 or more days of drifting. And we have no idea how all those competing currents would push this thing around in that period of time, anderson. Frankly i have doubts as to whether or not you can come up with an algorithm that explains exactly where this thing would have originated, even if you get it here and determine that it is part of the plane. Anderson . Tom foreman, appreciate it. If these latest sightings in the new area do pan out and can help narrow the search for the 777s black boxes and if the sonar pingers in the boxes still work, what precisely would search vessels be listening for in theyre going to be listening for this. That sound is the sound of a sonar pinger. Youre looking at the distinctive shape the pinging makes on sonar screens, a spike that stands out from other ocean noises. Weve been talk about the black boxes and pingers and how theyre activated almost from day one. Tonight we have a demonstration with cnn safety analyst david soucie and david gallo coleader of the search for air France Flight 447. And david soucie, how does this work . Explain what you have here. A duquesne tester. Inside we have thats the pinger. 750 unit. Doesnt look very dra
