Don't plan on any drone deliveries from Amazon in Acadia.

The National Park Service has sent out a memo to all the parks under it's control to ban the use of drones in national parks. Unmanned aircraft have been causing safety concerns in parks across the country, which sparked the ban.

National Park Service Director Jonathan Jarvis wrote in a news release:

'We have serious concerns about the negative impact that flying unmanned aircraft is having in parks, so we are prohibiting their use until we can determine the most appropriate policy that will protect park resources and provide all visitors with a rich experience.'

All permits that where issued for drones will be immediately suspended until they're reviewed by the NPS. The exception to the ban is park service use of drones for fire and rescue responses or scientific study. Parks that allow the use of model aircraft by hobbyists or recreational use can continue.
