I think trespass laws allow you onto peoples land if you are not causing damage etc,however I don,t believe you are allowed to use a vehicle;quad 4x4 etc so I suppose an aircraft would be included in this unfortunatley so back to land owners permission I think.However chip light on! bad wx no one knows your there easier to get forgiven than get permission etc but I have never done any of the above.Seriously though landowners permission the way to go
