So I guess if some of the stolen passport guys were Chinese, well it could still fly.
What I like about it is that is where it looks like the flight path is headed. Xiniang or whatever.
In terms of the Uighur...as you said, they might have been on via stolen passports - or there might have been Chinese muslims from other parts of the country.
And...it could well be this was partially an inside job - that a Chinese muslim separatist group simply bribed one or both pilots (both muslim) to aid them in their purpose.
I just don’t see how this plane could make it past Indian airspace without being detected, or arrive in Pakistan without Pakistani government knowledge. But, if we are willing to suggest that much, that the Pakistani or Iranian governments would be willing to lend such material support to a hijacking - it would have been far easier to simply give the terrorists a plane, if that is what they wanted.
If was hijacked or pirated by all appearances. But, I think we would know if it landed safely somewhere by now. The fact we seemingly don’t, suggests that it was shot down. The Chinese would be the most likely culprit there...in my humble, tin foil opinion.
