I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Grit Fell lies about 5 miles East of Lancaster
Park in the free carpark next to Jubilee Tower
If flying from the carpark note that the peak of the fell is approx. 200m higher than the carpark, so set your max altitude to suit
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 29/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
