And since we all know that 1500ft is the ANO legal lower limit over a built up area. How, apparently recently, did an Islander do banner towing over London, at apparently, 1000ft? Isn't that a case to ponder? Isn't a potential 700kgs load a worry for Mr Plod or anyone with security worries? In my view this view from on high has no meaning or purpose.
I agree with DA in his wise words. Good points there sir.
Btw HD I can tell you that DA IS an airline pilot. Known him for years.
Oh and one more thing HD you quoted this:
It's NOTAM'd and ATC prevent any aircraft from entering. (London).
I have a great respect for you and your mates but you can't - can you. Not really. Not if somone is determined.
