I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Parking/TOAL: 51.411070, -1.624057
There is no information about this place, just north east of Savernake Forest. I haven't seen anything like it before, an octagonal area of trees in the middle of farmland.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 04/12/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
