Yes, I will have a face to face discussion with them, but being a non-pilot, they will try to pull the wool over my eyes. They believe that as long as they are landing, they can fly below the 500ft limit (rural) over my home. I don't know whether they have sought council approval to use their property as a private landing strip, so I will have to ask them and council. In all honesty, the lives of my children are not worth risking.
Thanks for the replies and if you have any more pointers for me about the legalities, that would be very helpful.
