We could easily build a pinger detector so we would run out and detect pingers. youd have to download the data but it would be geo referenced so youd know where the ping came from. these tools you can launch from multiple boats. >> david malco reported that the conditions are murky, the sea is churning and royaling and that its a mess under there. does that matter? >> it does for visual but for pinger and side scan sonar, it does not matter. you can use these tools in murky water. >> miles, the ...

This tow fish that were deploying off the "fort worth," they basically can do the job of a, the a tpo. >> you think theyll be able to detect the ping from the so-called black boxes -- >> the tow fish is capable of detecting the ping from the black boxes, absolutely. its also a side-scan sonar. so it does two things. it can map the ocean floor to help us locate wreckage and find it. >> but so far, no pings detected? >> nothing. >> as far as you know? >> no. >> lets say there is a ping thats detec...

15 of the 30 some-odd bodies. difficult to know where they are. possible many of them are still strapped into their seats. >> the dimpb rfference between the sampson and the fort worth? >> the sampson is designed for anti-warfare. the fort worth is the smallest ship we have in the nation in terms of combatants. and its a new class. completely different type of ship, different capabilities. >> these black boxes, they have these pingers and they have batteries, theyll go for another 20 21 22 days ...

Is where you want to look for the black box material. so they really should be looking at -- and im sure they are, looking at that raid yar ddar d me to determine where the plane was last known to be. most loss of control accidents have the plane being within 25 miles of the last known location. if the wing came off and severe icing that brought the plane down or other struck trstructur failure, it should be close to that point. we dont have a window into what theyre doing at this point, but you...

Thorough search of the ocean bottom to find is the debris field in total like we did on twa flight 800. we ended up with three distinct debris fields that told us a lot about whapt happened to that aircraft that it came apart in three different sections and thats what they need to do now and then as they find these debris fields they move the sonar off to do -- continue their search and then they get the remote operated vehicles and the divers into those debris fields and do an eyes-on that part...

This point. >> okay. there are at least two u.s. warships in that area. the "u.s.s. ft. worth" that just arrived. and you talk about the sonar capabilities. the sonar, we understand from which ship actually located four more items. how might the sonar help detect the black boxes? and would that typically be the way in which those black boxes are located? >> well typically, you dont use sonar to detect the black box, or the sonar or the ping from the black box should show up on the sonar record. ...

Piece of information. data about the air speed, altitude pitch, acceleration roll fuel. and the list goes on and on. but to make sense of the data first you have to find it. not an easy thing to do when a plane crashes into the ocean. both black box components are outfitted with underwater beacons. which self-activate the moment they come into water. they send pings to transmit information. and to transmit data as low as 20,000 feet. when the batteries run out but on land theres no such ping for...

Peter goelz a former ntsb managing director. about 24 days before those pings go dead. why is it taking so long? >> it hasnt been. >> almost a week. putting that in perspective, given that these black boxes have the pingers. >> the ping can be picked up by a matter of a couple of miles. or two or three kilometers depending on the nature of the sea. youre not going to put the locators in there to search for them until youre pretty certain that youre in the area. it would be an act of desperation ...

Miles away from the wreckage. it could even be conceivably be on dryland. this is a very important development. heather: you talk about the ping errant ability to trace that. time is of the essence and also the debris itself as we go day by day and the weather conditions deny access to that area. the debris is being spread across a wider area as well. >> some off it is being found 100 miles away from the last reported point of the aircraft. these are the old pinger batteries. right now they have...

Boxes may explain what led to this disaster. but how will searchers look for the plane under water? first, they will likely listen for it. all commercial airplanes are required to carry pingers, underwater locater beacons attached to the black boxes. they emit a ping once a second. >> its really simplified an under water microphone. this is the type of device theyll tow behind the vessel and listen for that pinger locater. >> how far can it hear? >> about five miles. >> unlike the extreme depths...
