But I could be wrong...
Creamie,
Yes, you could be, but nobody is going to the High Court to find out.
For my part, I have an open mind (but it is not open at both ends) as to the enforceability of airspace "restrictions" that have no legal validity, regardless of the state of registration of the aircraft.
You may recall, almost 20 years ago, now, an N-registered Navaho was deliberately flown just outside the Australian territorial limits off Williamtown, when various R were notamed as active, despite much huffing and puffing, no action was ever taken, because there was no cause of action.
Tootle pip!!
