Has anyone bee able to get FAA approval to fly in a Class D 0 ceiling? I own a Mini 2 series drone and have always been denied by drone zone to fly regardless what minimum height I request. I want to follow the rules but I see toy drones that can fly much higher than my drone without having to get FAA approval. Are there any provisions or rules I can cite that I can fly below tree tops or below the roof of houses in my area and without getting FAA approval? Thanks all.
