This reminds me of a serious
PR Gaffe a few years back at the National Eisteddfod when it was held at Swansea. There had been complaints that the previous years Eisteddfod had been seriously disrupted by aircraft noise. So with much ballyhoo it was announced that a strict exclusion zone was to be established and this would solve the problem. Low flying in general was something of a thorny issue at the time.
Shame nobody told the drivers of the loud pointy things! Having the offenders shown on live TV made it hard to deny and to crown it all as the Eisteddfod reached it's climax with the ceremony to Chair the Bard they reached the point where the Arch Druid asks "A Oes Heddwch"*, they had to stop because nobody could hear a word he was saying. The timing was exquisite, it couldn't have been better if it was planned. I believe questions were asked in the house about that one!
