Cover up
I live in the region and have been following the thread and a lot of the available publications in the press with interest. I am convinced, that something really crazy happened that Malaysia are trying to cover up. Maybe a high jacking gone wrong, just can't make up my mind if they crashed by themseves (but why would Malaysia cover it up) or they were shot down by Malaysian military (or something else very crazy).
I am just sure of something: China will be very very angry very soon, about being fooled by Malaysia. How many millions have been spent by almost a dozen countries looking in the wrong place. Malaysia will have no choice but to come out with the truth. I do not even understand how Malaysia can start searching on its west coast but denying it had any hint that the plane headed that way. There is something so obviously wrong and not matching, I am in fact surprised that China hasn't really made a big fuzz yet....
