Just following this up as it's on a thread on private flying. As for 'Beadwindow'...
My barber knows more about the comings and goings at Waddo than I do and I fly from there......I'm not joking either....
When I was at Coningsby if you wanted to know when the next Taceval was you asked the landlord of the Black Horse.
Honestly to get uptight about 7500 as if it's some state secret is ludicrous, it's like getting uppity about military frequencies that are readily available in Pooleys.
