Home owner who took on RAF's 'Hooray Henry" pilots Mr Jones, a chartered surveyor, began contacting the RAF after becoming concerned that jets were flying as low as 200 feet over his business and properties he rents out at Cefni, near Llangefni, north Wales, which include a children's nursery. He added: "Are our children being subjected as some say in the village to punishment by a gang of Hooray Henry's for daring to ask if they will fly over open fields instead of a children's nursery?" Despite his pleas, the RAF refused to budge. So last month, he wrote back saying: "Since you have refused to send independent observers to Parc Cefni I will be arranging for a weather balloon to be raised daily at the corner of our property to a height of 499 feet. It will be taken down each evening at midnight. Please notify your pilots accordingly. Mr Jones said he was shocked to receive a visit by the police three times - the first within 48 hours - claiming they had received a complaint from the RAF that he was being "threatening." He said: "I told the policeman that I was proposing to put one up because the planes were scaring the children." He said the jets were travelling at 400mph and "as they get to the edge of the property they open the throttle and give it a hell of a blast." A spokesman for North Wales Police said: "RAF Valley were concerned as a balloon at that height would cause danger to military and civil aviation as well as the general public." He said conversations with Mr Jones were "amicable" and that he had agreed to make a formal application to the Civil Aviation Authority. A spokesman for RAF Valley said: "We regret that Mr Jones has had cause to complain. Our pilots try to fly their aircraft in a way that causes the least disturbance to people on the ground. They are instructed to try to avoid direct over-flight of the Parc Cefni children's nursery whenever possible, but for a variety of reasons this cannot always be the case, not least due to the nursery's close proximity to the airfield.
