I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission obtained.
Castle sinclair is towards the outer boundary of Wick/John o groats Airport FRZ, I rang the ATC to ask permission to fly for 1hr before I left on holiday, i intended to fly on the 4th of February which was a Saturday, I was to told the airport was closed on Saturdays, and i could fly for as long as i wanted
The originator declared that this location was inside a flight restriction zone at the time of being flown. Permission to fly was obtained from Wick ATC . It remains the responsibility of any pilot to check for any changes before flying at the same location.
