Doug, what's the latest on the search? >> reporter: it was an unproductive day. a storm so common in that area of the world has called off search efforts. the malaysian. he announced yesterday at the plane went down in the middle of the southern indian ocean. some saying the malaysian government's response to this has been inept again has demonstrated incompetence with that remark. >> i would love to hold out hope for families but that plane went south. >> reporter: the radar analysis was based on new techniques based on the doppler effect. when a train passes by or a car passes by and you hea...

Assumptions regarding auto pilot speed. the analysis arrived at a path of flight which was peer reviewed by britain's air safety agency. the air accidents investigation branch. before being submitted to malaysian authorities yesterday. >> this is the first time we've ever been asked to try to find something with just a single signal once an hour. really a great tribute to our scientific team they managed to achieve this. in very simple terms, we have used the difference in speech in which the signal has come from the aircraft to the fixed point, the satellite in space. it's called doppler effe...

This is called the doppler effect. the inmarsat technique analyzes the difference between frequency at tha a ground station expects to receive and what is actually measured. this difference is the result of the doppler effect and is known as diverse frequency offset. diverse frequency offset changes depending on the location of the aircraft on an arc of possible positions. its direction of travel and its speed. in order to establish confidence in this theory, inmarsat checked its predictions using information obtained from six other b-777 aircraft flying on the same day in various directions. ...

Now, what we know is that this working group will be heavily reliant on the data that particularly countries like the united states and the united kingdom can offer. we know that they relied on the united kingdom's inmarsat satellite data, the doppler effect that looked at the frequency and velocity of the aircraft to work out that it did likely end its journey in the southern indian ocean. which is why they decided to go and announce that they believe all hope was lost in finding mh-370 and those on board alive. wolf? >> saima, you know that malaysian authorities, malaysia airlines, malaysian...

The northern pathway because none of the pings we got match with the northern route. but they have much match with the projected southern route. the match is pretty much inescapable. martha: he then went on to say i wish i could tell these families there i any hope, but he believes there is not. >> i agree there isn't any hope but i don't agree that's the final word. martha: when you look at the technology they are using. they talk about the doppler effect. if you drive down the street and you honk your horn people at different points along the way will hear different frequencies of the horn. ...
