I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Can't find any information on this water tower, other than it was last cleaned in 2011. It certainly stands out when driving between Malmesbury and Cricklade. Parking and TOAL was from a lay-by by the tower. The are telegraph poles next to the tower, so be careful.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 20/03/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
