No one ever said anyone was hovering close to others, just close to themselves. It goes without saying that being courtious to others and following the rules is expected. The question was asked why anyone hovers close to their own plane. Why is that dangerous to bystanders? I see people ride motorcycles without helmets. In many states there is not a helmet law so why do I care? I think its crazy to ride a bike without one but who am I to worry about others endangering themselves. Now if someone is hovering a plane close to other pilots or close to spectators, then that is different. That's not what this thread asked originally.
