There was something interesting the other night on TV, which I hardly watch, but tuned in as it was all factual rather than speculative.
They were saying at some point, some of the blame will go to Malaysia Air traffic control. Failing to react to an unknown plane in their airspace, and did not scramble any jets from the air force to investigate the live unknown aircraft.
University researcher from Melbourne and US counterpart state it was a perfect crime. "It is no coincidence that the plane ended up at the deepest part of the world's oceans." In any event, sad situation all round.
