FWIW it looks like the "Japan bound captain RT" and the "Oil worker fire in sky" stories are both full of holes and probably hoaxes.
The Nanning landing story is more credible. Just.
People seem to have forgotten that the authorities think the last two pings came from the same location and that the last ping was on the ground.
Also we know the ELT hasn't gone off.
These are amongst the hardest evidence we have.
So the flight hasn't crashed.
Isn't under water.
Hasn't ditched.
It really does look firstly like it is northern route and secondly that it has successfully made a proper landing at one of the thousands of possible locations.
Whoever planned this was meticulous.
It would help investigation if it was known what their motives are.
