Drone sightings and how to handle them
Most reported sightings are lawful activity or something misidentified. A short written procedure covering what to record and who to tell is more useful to most organisations than equipment.
Key facts
- A large share of reported drone sightings turn out to be aircraft, satellites, stars or planets, or lawful drone activity, particularly at night when distance and size are difficult to judge.
- The useful record of a sighting includes time, duration, direction of arrival and departure, estimated altitude and distance, observed behaviour, and any photograph or video.
- Where flight operations are affected, a sighting should be reported to the relevant aviation authority and air operator as well as to local law enforcement.
- Since 1 July 2026, eligible state, local, tribal and territorial law enforcement agencies may hold counter-UAS certification, which makes local reporting more productive than it previously was.
- Nuclear power plant licensees operate under an NRC requirement to report drone sightings over their facilities to the NRC, the FAA, the FBI and local law enforcement.
- A pattern across several sightings is usually more informative than any single event, which is why consistent recording matters more than the detail of any one report.
Most sightings are something else
Judging the size, distance and altitude of a light in the sky is difficult, and it is considerably harder at night. Aircraft on approach, satellites, bright planets and lawful drone activity are all reported as suspicious drones, sometimes in large numbers during periods of public attention.
Reports should still be taken seriously and recorded consistently, because a description that cannot be checked afterwards is very hard to act on.
What to record
A useful sighting record covers the time and how long it lasted, the direction it arrived from and left in, a rough altitude and distance, what the aircraft appeared to be doing, and anything distinctive about its size, lighting or sound.
A photograph or video is worth more than any written description, including a poor one taken on a phone. It is the part of the record other organisations accept.
Where the site receives Remote ID broadcasts, that data adds an identifier and a track, and in many cases the position of the operator.
Who to tell
Local law enforcement is the usual route, and it has become a more productive one. Since 1 July 2026, eligible state, local, tribal and territorial agencies may hold counter-UAS certification, so a local force may now have capability it previously lacked.
Where flight operations are affected, the aviation authority and the air operator should be notified as well.
Some sectors carry specific duties. Nuclear power plant licensees operate under an NRC requirement to report sightings over their facilities to the NRC, the FAA, the FBI and local law enforcement. Airports and other regulated facilities should work from their own applicable requirements rather than a general description.
The pattern matters more than the event
A single sighting establishes very little. It could be a hobbyist, a survey flight, a news crew or a misidentification.
Several sightings, recorded consistently, start to show something: whether they cluster at particular times, arrive from a particular direction, or concentrate on a particular part of the site. That pattern is what supports a proportionate decision about whether further measures are justified, and it is what makes a funding case credible.
For most organisations, a one-page procedure covering what to record and who to tell is a better first step than equipment, and it costs almost nothing.

FAQ
▸What should staff record when they see a drone?
Time and duration, the direction it came from and left in, roughly how high and how far away it was, what it appeared to be doing, and anything distinctive about it. A photograph or video is worth more than a description, even a poor one. Recording this consistently is what allows a pattern to be recognised later.
▸Who should a sighting be reported to?
Local law enforcement in most cases, and additionally the aviation authority and the air operator where flight operations are affected. Some sectors have specific duties, and nuclear licensees in particular operate under an NRC requirement to report to several bodies. The reporting route should be established in advance rather than worked out during an incident.
▸How many reported sightings are real?
A substantial proportion turn out to be something else. Distance, size and altitude are genuinely hard to judge at night, and aircraft, satellites and bright planets are all reported as drones. This is a reason to record carefully rather than a reason to dismiss reports.
▸Does a single sighting justify buying a detection system?
Rarely. One sighting establishes very little, and most organisations get more value from a written procedure and consistent recording. Where a pattern emerges over weeks or months, that record becomes the basis for a proportionate decision and for a credible funding case.
