About a month and the plane disappeared march 8th. today is april 5th. time is of the essence for those searching for malaysian flight 370. chinese news report say a chinese ship picked up a signal in the southern indian ocean. at 37.5 kilohertz. thats the same frequency emitted by the planes black boxes or flight data recorders. malaysian authorities say theyre trying to verify the report. the chinese also say one of their air force planes spotted some white floating objects in the search area....

Failure, it would be because of fuel starvation or intentionally cutoff. this reasons the planes altitude if flight mh-370 dropped to a lower altitude heres where we would see a change and if someone onboard deliberately altered the flight path, we will see this line start to dip or rise depending on the direction. >> i think one of the important things that people will be looking at is who was in control of the aircraft. so when we look thea t a so when we look thea tt the datm the flight data ...

That yet. why wouldnt they be? >> well, brooke, the primary purpose of the existing pingers is to locate the actual location of the data recorders and voice recorders within a debris field, not to find the debris field itself. their short range makes them not really adaptable to a wide search area. thats what were faced with. what were trying right now, the australians and the navy are trying, sort of a low-probability last-ditch effort, if you will, to try to get a signal from their best idea o...

It basically tows behind a ship up here and listens to see if it can hear the black box, data recorders pinging on the bottom of the ocean, to see if they can find them. you have to get pretty close, within a couple of miles and this is a slow laborious process. the ship up top is traveling only four or five miles an hour at best. if youre standing on the deck, youd have a light breeze in your face. thats the passive sonar. its listening for anything it can find. beyond that theres also some act...

Them so divers dont get hurt. >> underwater obstructions are a concern. we tend to fly the auv at about a 45-meter altitude of the bottom. keeps us usually out of the way of obstructions. >> reporter: these types of searches can take months or years. but the payoff is high. wreckage that gives clues about what happened, data recorders and the thing that matters most, the fate of the people on board. rosa flores, cnn, new york. >> so thats an idea of how its going out there. but right now, chad m...

Zone were told has been similar, relatively calm seas, which was good for search crews today, because they werent distracted by those white caps on the waves. white caps that could easily be mistaken for possible debris floating in the water. even though the visual season is over for the day and planes from a number of different countries flying back to the air base in perth, we know the underwater search, the s.o.n.a.r., is going to be active 24/7. their u.s. navy towed pinger locater behind th...
