I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Small reservoir and large water treatment works on the banks of the Thames. Lots of boats. Easy to keep VLOS and to avoid overflying and proximity of people. Be aware on helicopter flight route, but felt clear view to see and able to reduce height easily and quickly if needed. TOAL from public steps into the river on the Southern Towpath, access West from Cherry Orchard Road
Parking easy on residential streets. TFL and Surrey Buses Bus Stop on Walton Road.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 27/08/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
