It is very sad and very fascinating all at the same time. I actually know someone who was close friends with 2 of the Aussies on the flight....I am doubtful of a hijack scenario as surely a number of people would have gotten a text off to someone at the very least. Whatever happened had to have been very unexpected and very quick.
I am very doubtful of them still being alive somewhere also, (though I want them to be), it just doesn't make any sense that a rather large plane could land somewhere and not be noticed - it's just so unlikely.
I think like that French flight years ago, they will find the plane eventually somewhere deep in the ocean.
I don't subscribe to the various theories of various countries shooting the plane down....but then I don't think politically.....
