when I visit my grandma there's these 2 hot air balloons that tend to fly over the area of her house and I want to take my drone to take pictures but I can already identify 2 possible issues. 1. what does the FAA say about flying near/around hot air balloons and 2. how would I make it clear that I am not a threat. I'd figure I could spin in a circle or something to show pure intentions but I can see how the passenger in the basket could freak out from a random unknown drone randomly approaching the balloon
