Can a property owner restrict the airspace over their property. I wanted to photograph NHMS (New Hampshire Motor Speedway)from the air. I checked their website for drone restictions and it said no drones allowed to fly there including the airspace above the property. Well I'm thinking they can say that but really have no authority to say you can't fly a drone over the property as long as you don't take off from or land on it. I checked NOTAMS and TFR's for that area and found none. So if theres no events going on,no people in the grandstands,, no cars on the track ,I would think it's ok to fly over and take pictures. What say you all?
