The fire department usually will not help unless you have a friend there. You could call them and say you think there is a cat in the tree (kitten works best) once they get there tell them you lost site of it but you think you can guide the bucket man to the spot. Once he is up there you say, hey what's that,,, pointing to the drone. If they bring it down say something like this, (how about that, I know who it belongs to and I know he will be glad to get it back.
Now you all know this was a joke right? Truth is, I have a lot praise and respect for the first responders.
