How could you be bunged in the slammer? You are legal in all respects to operate the machine IAW IFR world wide, unless you happen to be a European living in Europe. They'd have to prove your residency - next to impossible in the space of a few hours. And then the "residency" test would have to be tried in court - is the operator resident in EU land or not?!
What would happen to a Norwegian who did this?
