Something else that
"Would Never Happen Here"
The yanks have this really strange idea that everybody is entitled to use the US national airspace, it is NOT a matter of $$$$$$ talks and little aircraft can sod off.
Just fancy that,
you fly by right, not by a bureaucratic grant of a "privilege" that can be limited, circumscribed or just plain withdrawn at the "whim" of "somebody" further up the food chain that pulls more lobbying weight.
And the US military DO NOT have first right of refusal on the whole lot, with civil with what's left.
And, as I have pointed out so many times, all that military restricted airspace around the Australian coastline but outside the 12 mile limit has precisely NIL legal validity ---- hence the USN regular
"freedom of navigation" exercises within Australia's economic zone.
Tootle pip!!
