The bikers were active again on Saturday and Terry advised me by email that they had permission. When they rode up to me and Pete Wilson, we tried to have a word but they spun round and went over to the far side of the farmers land. However they continued to ride under our flying area and the track alongside the hedge cut out. Terry confirmed that he would be re-confirming with the Farmer that the bikers would be advised to come no closer than the large tree furthest to the right of the hedge cut-out and as such, if any of us witness repeat activity, we could politely point out this agreed proximity limit to them. I agree with this course of action, as we shouldn’t fly within 50m (30m on take off or landing) of them at any time and risk contravening our own rules and terms of our insurance cover etc.
