Just a small note of caution chaps. The good people of Thorney are a litte tired of people aerobatting in their vicinity (I met with the 2i/c there), so I would counsel using as healthy a base height as you can get away with in your aeroplane!
And yes, I do appreciate that our Extras ARE amongst the noisiest! I attended the Goodwood Aerodrome Consultative Committe recently and explained that we try very hard to vary the location of our activities wherever possible. The reception was actually very good, but we are never going to please all of the peoplke all of the time!
