Its pure arse covering. NOTAM the whole of scotland that there is an exercise on. And state that you shouldn't operate in that airspace.
What are all the flying schools meant to do shut down for the day with no compensation?.
In scotland we are all aware of fast jet activity just like wales and the other areas of intense activity.
As Maoraigh1 states though I supect if the worst happens the RAF is down one of its very few aircraft thats servisable hopefully the crew will bang out. The light aircraft won't be around to face the news and there will be another chinook type investigation with the RAF saying it did the right thing and a load of civi lawyers going through them like a dose of salts.
And it being scotland, the legal system will stick the middle finger up at any pressure from London to sweep it under the carpet.
