Do you agree with having a system that allows an aircraft to drill straight over the top of a busy CTR at 2500ft without talking to anybody?
If you are asking me if would I do that, the answer is no. Smacks of bad airmanship to say the least. As for the "system", well, I would use it carefully if it were an operational necessity.

To be honest, Francis. I am getting bored of thinking up new and more poignient ways of saying the exact same thing about the exact same airspace.
Someone defined madness as doing the same thing over and over again and expecting a different result.
