I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Best access is from Castle Street in Horsford. About halfway down the road there is a public footpath covered by trees. You can just about park in the lay-by next to the footpath and walk towards the castle (beware of nettles!)
Obviously this location is situated within the Norwich Airport FRZ so ensure you obtain email permission prior to flying.
The originator declared that this location was inside a flight restriction zone at the time of being flown. Permission to fly was obtained from Norwich Air Traffic Control. It remains the responsibility of any pilot to check for any changes before flying at the same location.
