Simple call the EU's bluff ask them for our share of their assets easily 35 billion. Then tell them that we're fine with everyone of their threats. We will get medicines elsewhere, our airlines wont fly over Europe but then neither will european airlines be able to fly over uk airspace, bit of a problem if you want to fly to the USA. Then lets tell them that any tariffs will be matched
well, there are no other sources of some medicine, and the tariffs will matter to us, not to them, also, the airplane thing is nothing to do with EU airspace, we can't fly ANYWHERE as all the governments in the world who allow us to take off and land in their countries only accept us as part of the EU aviation safety agreement, which we will no longer be part of and we are nowhere near being able to set up our own.
The civil aviation authority needs to buy and adapt premises, set up and police safety procedures, recruit and train thousands of staff, persuade around 25 separate governments to accept them as valid, then PROOVE they are safe through international inspections.
Then british planes will be allowed to fly.
It is nothing what so ever to do with EU airspace, and its not a case of you need to let us fly through your airspace, or you can't fly through ours.
we will not be able to fly anywhere, but EU planes will still be able to fly everywhere, so we are really not in a position to "call their bluff" as it is nothing to them, and everything to us.
Much like every other part of the "negotiations" really. We don't have any of the power at all. we can't call anyones bluff. They can call ours a thousand times over
Some german officials seem to be even hoping UK airspace will be shut down, as a lesson to anyone else thinking of exiting the EU.
