The Bryan County Sheriff’s Office received a report from the air traffic control tower at Savannah Hilton Head International Airport about 8 p.m. Tuesday night of a drone flying at about 2,000 feet that came with a half-mile of an inbound aircraft.

The report stated that the pilot told the tower that the drone was on the Bryan County side of the Ogeechee River. Deputies searched the Waterway RV Park on U.S. 17 at the river but could not find anyone with a drone.

It is unclear which flight was affected. Flightstats.com lists nine inbound flights to the airport that landed between 7 p.m. and 7:30 p.m. and no further arrivals until 8:23 p.m.

A fact sheet from the Federal Aviation Administration says all drones are considered aircrafts and thus people who fly them are considered pilots. Regulations say drones cannot be flown above 400 feet or within five miles of an airport.
