It absolutely does. The FAA restricts airspace up to 5 stories from the ground. You explicitly do own some airspace, but the state is desperate to keep that well below 5 stories. I think I've heard they've been trying to get it as low as 20 feet above the tallest building. I could have sworn I've heard it's somewhere around 100' to 150' feet.

That being said, this is just what I can remember, I'm probably wrong.
