I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Waitrose 'customer' parking very close to the Thames and Severn canal towpath with picnic area and benches at location. Can be busy with walkers and cyclists and the trainline is active so take care to avoid issues but nicely accessible site.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/08/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
