I still see no evidence to support your claim, just generalisations. However, I do accept that the activities taking place north of Newcastle cause concern for people transiting between there and Aberdeen direct at medium level - let's leave it at that shall we?
Still don't buy the Danger Area Case. Surely increasing the amount of Class A increases the probability of penetration?
I don't actually understand the latter part of your last sentence, but I do not consider that the mostly military traffic in that area is anything like 99% predictable. Sixty percent tops! I am astonished that you suggest cost overrides safety as the only real factor forcing traffic to go direct rather than via CAS.
