Which reminds me of the time when the CAA's consultation on charges was raising my heckles: Has anyone actually ever paid the £97 for an "Exemption in relation to overtaking (Rule 17(4) of the Rules of the Air)". Few people seem to be able to remember which side the rule states, let alone require an exemption from it. Yet another bureaucratic irrelevance, which kinda sums up the CAA really....
