You guys have obviously never been out of the kindergarten that is Australian airspace, try operating anywhere in Africa from the Sahara south, running through the red sea "station calling Cairo" while dodging ELAL transiting right down the FIR boundary not talking to anyone or transiting Kaos Corner in the eastern Mediterranean in a jet with magnificent variations on language, aircraft performance, human performance, and toss in a sky god or two..... and the US military messing with GPS signals every now and then.
TIBA pales into insignificance.
