Well what about all the passenger aircraft on Advisory routes that our pointy headed friends with their arses on fire seem to ignore ? THAT is an accident waiting to happen. Tornados out of Lossie and Leuchars, other NATO fastjets, controlled? by AWACS who have no concept that these are civil aircraft and that the civil ATCO is trying to avoid them. It's bad airmanship from the military.
What if someone were to fly an aircraft outside the ATZ of an RAF base but inside the MATZ without bothering to speak to the RAF ATC ? Same idea !! So why can't mil jets do the smart thing and recognize Advisory Routes, and get a radar service before crossing.
That would be a good topic for a program, but of the course the BBC never bother to venture (too far) north of Hadrian's Wall.
