Inmarsat used to track this plane after it disappeared. these numbers were used to measure the way that a ground station sent a message up to a satellite up above the indian ocean, which in turn relayed that message over to the plane, electronically asking are you there and how the plane responded. and these 14 numbers in particular allow us for the first time to see the plane's movement long after every other tracking source had lost it. each one of these lines across here represents one of those electronic handshakes between the satellite and the plane. and you can see, if you look over here...

I was given exclusive access to inmarsat and to the man who led the team mark dickinson. and i asked him, when all was said and done, the goal here was transparency, it wasn't to let other people redo the work. >> to be clear, you're letting people make judgments on your work. you're not inviting them to redo your work. >> no. as i say, to redo the work requires experts in many different fields and we gathered those victims within the investigation team to allow that to happen. but this is providing some transparency in terms of what actually data came back and forth between the plane and the ...

Transparency in what data came back and forth between the plane and ground station and how that data has been subsequently used. it allows people to see what techniques, what things have been accounted for. but certainly provides i'm hope aggregate deal of transparency in ters of the analysis that's been done by inmarsat and almost by the other teams in the investigation. >> chris, the important point there is that they have done the testing with their model and other organizations have done the same testing with their own model on many different planes, including the same aircraft over dozens...

Handshakes. leading the team here was mark dickinson with his colleagues they dived deep into the data. >> there are three types of information that we. messages from the ground station to the plane and back again that tells you the terminal is switched on and powered up and we have some time information and in addition to that there was some frequency measurements. >> reporter: timings told them the distance between the plane and the satellite enabling them to create the so-called arcs. they then factored in the frequency differentces. dickinson's team concluded that mh370 had to have flown s...

Done, and we are in agreement? i don't know it will be. there will be many people who will try to recreate this, but inmarsat has not given sufficient information to do that, john. what they've done is give enough information that you can see, or one can see, how they came to the answer that they've come to. >> they also didn't release the other analysis from, say, rolls royce or some of the other parties that were involved with poring through this data with them. i know that's something you focused on, richard. >> reporter: i think that's the weakest point they're going to face. it's understa...
