or assuming it s a crash, we don t know where the plane is. we don t have all the answers in terms of the plane itself. what other information, clues, might investigators be taking a look at or considering at this point in the investigation? well in the case of mh-370 there were a whole other set of data that turned up meaning primary military returns and later these satellite communications pings. now this plane did not have satellite communication systems. that s not going help us. also was not using an a card system. in this case we have a much smaller set of potential data to look at. we have to go out and find the range. it s not a huge area. not the middle of the atlantic or middle of the indian ocean. shouldn t be that hard. we heard recently people were speculating it s at the bottom of the ocean. no reason to think this plane landed in one piece. i don t know why they said that. usually in the ocean it breaks up.
the second extraordinary strand is the extent of interdisciplinary experts. you have experts that are space scientists and physicists looking at the satellite data and the transmissions between the satellite and plane. my colleagues and i wrote a story that explain in arcane way they looked at the temperature of the satellite and the temperature of the satellite communication systems on the aircraft and they were able to use these temperature variations to determine slight fluctuations in the frequency of the communications in the radio waves. this is one more element to try to get closer to where they really think the plane hit the water. interesting. rob, i understand you have been down deep, a couple of miles below the surface. what s the pressure do to a
