Have a look on the Flight Radar print out, a number of acft where in the general area, I find it hard to believe that between these aircraft and the number of boats around, no-one saw the supposed 'explosion / disentegration'. It does make me wonder if this was a controlled deviation and deliberate act which would mean that the search area could be out by hundreds if not thousands of Kim's. Surely if it had been a technical problem the Malaysian would have some info to back this up, even the Air France incident resulted in ACARS error messages being sent back to maintenance.
Why all the speculation about military radar showing the acft plunging to the sea whilst authorities denying all knowledge. The total lack of witness accounts and reliable radar traces and an apparent flow of misinformation makes me very suspicious of what has happened here.
