That got your attention didn't it? It actually is a question about it, and I'm looking at a Litchi flight plan but I'm curious if anyone's run into this. It is not about flying in it's about flying through a National Park. They own property on both sides of the river in a small stretch but not all on the one side. Here's the question. I have a National Park that has a fairly good sized river that runs by it. 3-400 yards minimum wide in some places near a 1/4 mile. Big enough to have dams and rapids.It's also on 3 state lines which makes it more interesting. None have drone laws that ban it. Now I have no problem at all with not flying in a National Park. I don't want to see a drone climbing El Capitan or over Yellowstone. What's good for one I'm good with for all. But now it gets sticky. I want to fly the river. Now before you say no, there are also Federal laws on the books that say if your property has a navigable waterway you have to allow access If you live on the Mississippi you can't control the waterway. Not even if you own property on both sides. I can't set foot on your property - that's trespassing, But you have to allow me to traverse the river. So which wins? I'm thinking I'm legit. I know if I call the park they'll just say "no drones" and no discussion because for the average Fed employee that's the easy way out. I know. I deal with them daily. It's where stupid often goes to die. I'm just interested in your collective thoughts. Pretend you're a judge and you have to make a guilt or innocence call. Thanks.
