I got my original figures wrong, the cost of the initial enquiry was £75,000 not £750,000.
But nevertheless, it was a sham of an enquiry. CDC had to back down because they didn't serve the enforcement notice correctly and they were told by the enquiry that the council's case would be thrown out on this technicality.
Just an additional note to supplement Dave's - it's absolutely correct that this is all being brought by one fomer pilot, who rather interestingly, applied either as an instructor or CFI (can't remember which) with what was then Aero School Kemble several years ago and was unsuccessful. All of a sudden, Kemble is a nuisance to the community. Sour grapes methinks?
