Personally, I agree it's a silly place for a para DZ. However, all airspace is shared (well, mostly. Commercial Air Transport have first pick and the rest of GA have to put up with what's left) and in reality, the parachute mob have just as much right to use the airspace as all the rest of us.
As I said, together with the BPA, the CAA & NATS have an input into the approval of DZs, so you can guarantee that unless it's safe and has been risk assessed properly, it ain't just gonna happen! Just being in the wrong place for PPRune readers does not mean it will be turned down.
I'd hate to think that there was a 'them and us' culture creeping into PPRune
