If that last satellite ping is true (still find this not certain, since it's not as clear evidence as an actual message from the plane), there was only a little bit of fuel left.
So I think it becomes a bit questionable how when you put all the data together, it makes the whole scenario even less likely. Every bit of info makes the story less believable.
The plane would have been hijacked without anyone knowing, whoever did so managed to turn off all communications, even phones, avoid being subdued by a crew member close by such as co-pilot (so either he is taken out super quick or is working with him, making this even less likely) turned around, avoided radar detection, pretty much manages to take everyone out on the plane somehow, flew in high altitude, back down, then flew for hours until a satellite supposedly pinged it when it had less than an hour of fuel left in a location that contradicts the last know direction it took, so wherever it was going was on the edge of its reach, another strange coincidence, and no one makes any believable claim to having executed this plan. It's like
purposely the most far-fetched of missions. Not only is someone going to pull all of this off, but he will then keep the plane afloat to go as far as possible until there is barely any fuel left, without being detected by anyone, without being dealt with by the crew and passengers? Why make this the most complicated and risk-prone operation imaginable?
It seems to me there is a disconnect between the information released and the plausibility of where the plane could be.
Is there portable tech that exists that could jam all incoming and outgoing communications from an airplane, even from phones?
There was a story of garbled message being heard by a Japanese pilot who made contact with the plane, but this story was then denied. What if the airplane carried tech that allowed it to hide itself, causing the garbled message heard?
