Back to the topic not the inter-service mud throwing...
The airfield is still British Army owned, but the main runway is leased to Bertlsmann. He pays rent for the use of the airfield for a set number of landings per annum to 1 (UK) Div and also pays for the upkeep of the main runway. The British have a clause in the contract which only allows a certain number of fixed wing flights to use the main runway per year..hence the use of Civvie charters to the likes of Paderborn etc. Hope this clears it up.
