Thanks for those links Genghis clearly a world of difference between the documentation. Perhaps this sort of initial feedback (even a little advice) from those on the distribution list and others may save this company time and money in the long run.
This should not be a combative process and I have nothing against drop zones either. In my experience they can certainly have a very positive impact at the airfield they are based at. The issue is simply one of the suitability of the proposed location.
