Re: So now flying a kite...
Flying anything nearby an airport is a different matter, and FAA may have good reasons for a tighter control around airports (where even static items may be a danger) within reasonable limits - but asserting it has jurisdiction over everything above ground may lead to absurd situations.
Maybe I should start to ask the birds in my garden to follow proper FAA rules, or I'll stop feeding them in the Winter... and give the cat a FAA Inspector badge.
That said, I know some kind of advanced kites may be a risk too - just like airplane or rockets models. Maybe the difference is just they rarely appeal to the average moron, and are rarely sold at the local electronics store.
