Through here. this looks like a mess, like they rode around randomly, but they didnt, jake. what they did essentially is put a grid on the ocean. this is how they follow the pings, they go one way and then they look for perpendicular paths, and then they take the commonalty, and they can essentially cut that down. so undertakjake when you say ho is it now? maybe around 560 square miles now. but that is really much, much smaller than we have been dealing with in almost every report. >> and tom, t...

After the plane vanished. sources also tell us that investigators are confident it was the flights captain who radioed in that last message and there was no sign of stress or possible third party when he said "good night malaysian flight 370." this morning search crews discover a possible new signal, raising hopes that they may be closing in on the flights so-called black boxes which could explain exactly what happened. lets begin with that new signal. cnns will ripley is in perth, australia. go...

Boxes. the air search is resuming now in the smallest area yet with ships crisscrossing the area around the clock. cnns tom foreman is digging deeper into the huge challenges searchers are still facing. what are you finding out, tom? >> wolf, when you go under water, thats when it really gets complicated. heres one way of looking at it. more people have been to space than have been in the deepest parts of the ocean. and this area with the target zone anywhere from 1 1/2 to 3 1/2 miles down. that...

Hundreds of miles away. >> so captain gurley, if they never find any debris, does it matter in the search for those black boxes? >> well, carol, i think its important to remember -- to look at the fact were really doing two searches now. theres the search that is proceeding on the ocean surface for any floating surface debris that may have -- still be there for still floating around and dispersed by the winds and currents. but the second search is on the ocean bottom. thats the real debris field...

The captains background or in his flight simulator that indicates anything amiss. but there is this -- the performance of the aircraft, how it got into the ocean hopefully 1,000 miles, if were looking in the right place, from perth, is inexplicable and has to involve some degree of human kror. >> mary, when they do find the black boxes and i think they will. five separate signals have been picked up in one general area, although its a large area. it seems like theyre going to find those black bo...

If you go all the way down to the deep ocean where this pinger is, what were talking about is the deep area at the end of the long slope that theyre dealing with in this area. it is more than three miles deep. over here, more than one and a half miles. this is generally believed to be around the two and a half mile deep zone. that is plenty deep for all the equipment we have that might reach it. if you go below that youre relying almost entirely on robots. and placement along the ridge, jake, ma...

Ocean shield is towing this pinger locater searching for flight night. my experts are back to answer your questions for you. this tweet is for david. it says will the extreme cold of the deep ocean help pinger batteries last longer? any mathematical estimates from your experts? >> i dont think it will. it is supposed to go 30 days. it has a buffer but that includes the testing at cold, hot, whatever temperatures, but not hot hot temperatures, of course. but normal operating temperatures. the col...

In 1986. in that case the pilots ran out of gas and were forced to make an intentional landing. even that resulted in significant debris on top of the water. >> water is like concrete. if you hit it regard enough, it destroys the planes integrity. it will open up things like compartments and sections of the airplane that have items that will float. >> the best case scenario for the malaysia airlines plane would be the type made by captain sully sullenberger on the hudson river in new york city. ...

Could explain exactly what happened. even as searchers continue to hear pings believed to be from the black boxes, not a single piece of debris has been found in the search. is it possible the plane stayed intact while sinking to the bottom of the ocean? some experts believe no matter how the plane might have come down, there should be at least some sort of debris floating on top of the water. gary tuchman has more. >> reporter: not a spec of wreckage has been found from malaysian airlines fligh...

They were farther away. it could be buried. describe the silt and how deep could it be? >> this stuff is we call it marine snow in the deep ocean, the bodies of old plankton rain down and over time it forms thick layers of ooze. this can be up to a mile thick. >> a mile thick? >> its not likely were talking about a thin veneer. this is thousands of feet of thick, sticky ooze, a mix of clay. >> i had a twitter question earlier and i couldnt answer it and now i can because you can. with the pressu...
