Citing visitor safety and park resources concerns, unmanned aircraft is now prohibited in the airspace above all lands administered by the National Park Service. So don’t get any ideas about having a drone make a food drop while on an extended backpacking trip in a national park.
All permits previously issued for unmanned aircraft will be suspended until reviewed. Superintendents who have previously authorized the use of model aircraft for hobbyists or other recreational use may allow such use to continue.
The National Park Service may use unmanned aircraft for administrative purposes such as search and rescue, fire operations, and scientific study, but these uses must also receive prior approval before being initiated.
