I agree, none of the information that has come out about all this deviating and turning back has been absolutely confirmed by Boeing, the engine makers, the US government or the Malaysian or Chinese government, it’s all coming from “anonymous sources”.
My suspicion is that when the plane is found, it will be found near where it was supposed to be and a simple catastrophic failure caused by pilot error, mechanical failure or an old-fashioned bomb will be the explanation.
I believe the satellite "pinging" has been confirmed by Inmarsat.
