it sounds like you've taken a good approach in your experience of poor teaching.
With respected to the incident you mention, that was in gusty light winds i believe....
So i think we should ban kiting in light winds and stay with the strong ones.... i haven't yet come across an article (just tried a search too) reporting incidence of injury from school teaching in high winds....?
(i am purely playing the fool / devils advocate in my statement - just for those who don't find it resoundingly obvious)
But needless to say, i've read and seen lots of comments and opinions on here - few that are constructive - many that are "i think i saw"... "a mate told me".... with few facts and even less positive action such as yours FDVJ
The fact remains that some like kiting in high wind, some dont (and as such often condemn those that do)
There is no law dictating maximum winds - albeit there are recommendations
If you see what you deem to be unsafe teaching practice at any spot, get the facts, and report it appropriately - (if not then you should come on here and vent your opinion at others who are just as frustrated as you that they're at work and the weekend forecast is poop)
And lastly, no one on here knows the facts about the lesson that stated the conversation.
