The most amazing thing to me is that not one country in that region scrambled fighters to intercept this jet, especially in the post 9/11 world. Or at the very least asked from immediate help from one of the larger nations in the region. I’m sure Australia could have thrown something together, and I bet the US Navy was somewhere in the region.
But there should have been jets on this thing almost immediately, and with the help of some tankers they could have tracked it until it went down and then maybe we don’t have this mystery.
Even if they do someday find the wreck, I’m not sure if they can actually solve what happened. The flight recorders and CVR won’t last forever on the sea floor, and are very likely already unreadable.
