we know one thing from the thai radio report by the way. the report that came out today they said they did not enter thai air space. does that mean they weren't going north? i think so. >> unless you also -- there was also a report about another plane that had been contacted by authorities in vietnam to see if they could make contact with flight 370. to you, that's significant? >> yeah. my understanding is that that airplane was about 30 minutes ahead which is a fair distance. and it's difficult -- the procedure that i was explaining before we went on air was that if the controllers are expecting an airplane at a certain spot, it seemed very compelling to me that they decided to attempt contact with the airplane. that means, where are they? in other words in their head they're saying, where is this airplane? so the first attempt would be to contact them on the frequency they were designated to be on. then they would attempt on the guard frequency, which is the emergency frequency. after that they would try to relay through another airplane. so it indicates to me that maybe the problem was developing but for that other airplane, it's not uncommon to not be able to contact them as a favor to air traffic control to relay
