I was just being nice. Your continuing question was irrelevant to my posting.
You said: >What, in your opinion, would constitute a reasonable request?
I responded: Any request from any FAA facility having airspace control of the area being used. Example: "We have a situations that may be impacted by your activities and we need you to stop your activities until further notice. We will get back to you as soon as the situation is resolved". In that situation, nothing more, I repeat, nothing more is required, nor should be expected, for us to "right now" stop our activities. We should assume the request is for safety of flight operations. Any attitude, such as, "give me a better reason or you don't have the authority", is counterproductive to our continued activities, in the short and long run. Also, in the short run, a distraction to the FAA controller, he or she, can do without.
Just my opinion.. Fred
