Justicair
Ludham is just up the road from me. It is a privately owned field (its actually concrete - about 800 meters from memory). The web site used to have mobile numbers for the owners from whom you can get PPR. There is not usually a problem with permission. The westerly runway approach is offset to avoid the blister hangar at the end.
The hangar is at the end of the runway. Hence the available runway is reduced.
