From the Federal Aviation Administration:
The Federal Aviation Administration (FAA) released a new list of pilot, air traffic and citizen reports of possible encounters with unmanned aircraft (UAS). The reports cover November 13, 2014 through August 20, 2015.
Because pilot reports of unmanned aircraft have increased dramatically over the past year, the FAA wants to send a clear message that operating drones around airplanes and helicopters is dangerous and illegal. Unauthorized operators may be subject to stiff fines and criminal charges, including possible jail time.
