I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Seathorpe Avenue, Minster in Sheppey. Small free car park and a short walk to the sea in a wide open area. Great views of the coastline and cliff edges and also The Leas beach front. Some great waters edge photography possible here.
Only notable caution is general public and dogs, but so far everyone is extremely friendly. Suggest take off and landing when clear of pedestrians.
Houses with wide open gardens with pools are on the cliff edge, so be mindful of privacy.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 14/01/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
