Organisations / Institutions / Land managers /Trusts etc think they control the airspace. They don’t. The CAA does.
I assume the police would be used for enforcement in the first instance though so not unreasonable in this case?
I smell a rat
I guess on the same basis as…
It’s farm land, private and he is allowed to fly it there.
Even if the land is private it isn’t necessarily going to be legal to fly there though surely?
be kept at least 50 metres away [from] private property
Eg there’s nowhere in my property i could launch a drone and satisfy that. Completely accept I’ve no real knowledge or understanding of it (nor do i fly a drone) but “50m from private property [you’ve no permission to use]” is very (well 50m) different from anywhere on property you’ve permission to be using.
I can also understand why they might not be keen on you overflying police hq etc, restricted airspace (i imagine it probably is) or no, there’s probably a few things they could potentially make l a nuisance with if they wanted to there given the nature of the building.
