That would be very difficult to establish, there’s all the VIP security for a start but the same squad look after MPs etc. You have to bear in mind their incomes from inherited land, is that Royal or not? It’s like trying to account for a rescue of a lost mountaineer, where the RAF Mountain Rescue and a Nimrod were called out “at £10,000 an hour”. Well yes, but if it hadn’t been for the lost hiker the Nimrod and the Team would probably have been in the air anyway doing an exercise where the scenario is a lost aircraft in mountainous terrain, etc. The same people go looking for civilian aircraft that go down, because guess what, it’s the same activity. It’s not as if they don’t cost anything when they aren’t on call out. My climbing rope costs me the same whether I am falling on it or it’s folded up in the spare room. Same goes for Sandringham, what do they do with it when Queenie's not there, run it as a holiday let?
