If some can all get over the self righteous, unjustified, posturing over pistongone, for following his clearance, we might get back to the point of the thread. To wit:
Why does any class D zone in the UK feel justified in refusing a transit?
Nowhere in Europe gets even close to LAX, yet VFR is whizzing around enough to make your head spin. Both through the corridor and vectored through the Class B.
I have asked the same question everywhere I can think of and I am genuinely eager to understand the reason.
The silence, however leads me to think that the answer is likely to be along the lines of:
"We don't want the hassle. OK."
