There are bound to be people in favour, and some of them in the local aviation community, and they have every right to express their opinions. I also can't see a fundamental problem with having a DZ in that general area, or with a drop aircraft being based at EGHP.
But the specific location. No.
Inside or immediately adjacent to the SPTA or Porton DAs - which could easily be within a dozen miles, then I think there would be no real issue for anybody.
And the proposer needs to get some grown ups to help write their case once they've found somewhere sensible to put their DZ.
