PUBLIC LANDS -- There's a clear case to be made in terms of safety, privacy and stewardship for requiring people to get special permits in order to use drones on public lands.

And for now, the ban on using drones in national parks gets a big thumbs up.

Another drone meets a watery end in Yellowstone National Park
Since the National Park Service recently banned the use of drones on the 84 million acres under its jurisdiction, violations have been sporadic in Yellowstone National Park. In two cases, the violators' drones have met a watery end: The first plopped into Yellowstone Lake.

The latest one crashed in Grand Prismatic, the park's well-known hot spring, where the 160-degree water makes retrieval of the unmanned aircraft unlikely.
