Yes but Vercingetorix they will see the airspace as a money generating addition to the tax payer so will want it as the resource. All they will see is cash flying overhead.
Especially if they don't get into the EU.
Some SNP type will wake up in a ditch on the west coast, check they haven't pee'd themselves again. Checked nobody has taken there half bottle out there jacket. Then look up in the sky and say those buggers should be paying to fly across gods country.
To be honest though I really don't see it happening so its a bit of a mute point.
