I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Car park on the edge of Rollesby Broad is free and has plenty of areas for take off and landing.
Easy to maintain VLOS as the two Broads are only separated by a single carriageway road that you can easily see over.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 09/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
