There used to be a daily NOTAM about kite flying in Hertfordshire. As it was close to a VFR route we use I rang the phone number given to enquire about the details. The lady who answered didn't know what I was talking about and didn't know what a NOTAM was. She said her partner sometimes flew a kite at weekends but hadn't flown it for months and he was at work.
I rang the NOTAM people and advised them that the info was misleading. I was informed they had no jurisdiction to delete the NOTAM and could only publish what they were given.
