Yosemite National Park press release from today states that the use of any types of drones are prohibited within the park boundaries. The full press release can be found here: http://www.nps.gov/yose/parknews/use-of ... l-park.htm The NPS press release cites a federal park regulation that outlaws the use of drones: The way that policy reads, there is nothing there that says drones. A drone does not deliver or retrieve a person or object. They follow the quote with a statement that this policy applies to drones. Sounds like what we've been hearing more and more, with an agency taking an existing law and trying to make it fit for applying to a drone. This NPS policy has been in place to keep people from flying aircraft into Yosemite Valley. RC helicopters have never been an issue before, but now they try to say that drones are the same as a Cessna or helicoper.
