this case is a typical example of the british disease. ie outraged onlooker doesnt like what he sees and says "there should be a law against it", but there isnt - never mind, we`ll make one up- and a few so called facts as well.
theres no rule of the air about prior permission and the chances of being prosecuted for trespass are about nil. I remember all the rubbish written about rule 5 in a recent thread. Jeez. some of you would only let us land at licenced aerodromes under supervision of a CAA inspector.
