Drone or UFO? How to recognize drones at night – and what only looks like a drone

4 min read

Colorful, blinking lights hover in place, then suddenly change direction, or a dozen points of light come together into a formation in the sky. In recent years, drones have become one of the main sources of UFO reports. But the story goes both ways: many people mistake drones for UFOs, and during drone panics, people mistake stars, planets and airplanes for drones. We show you how to tell them apart.

What does a drone look like at night?

Colorful, blinking lights. Most drones have red, green, white or blue LEDs. In the European Union, drones in classes C1, C2 and C3 are required to have a flashing green light so they can be distinguished from airplanes at night.
Hovering in place. A drone can stay motionless in the air for minutes, then suddenly take off, turn around or climb. This movement is unusual for an airplane, which is why many people describe it as a “maneuvering UFO.”
Low and close. Hobby drones fly a few tens of meters, at most a few hundred meters high. On a quiet night, the buzzing of the propellers can also be heard.
Short flights. The battery of most hobby drones is good for roughly half an hour of flight, after which the drone lands or returns to the pilot.
Drone shows. At events, hundreds or thousands of computer-controlled drones come together into formations and lettering. From a distance, especially if we see only part of the show, it can look like a mysterious light formation.

Why is it misleading?

Unusual movement. Hovering, sudden acceleration and changes of direction are exactly the features that UFO reports call “impossible maneuvers.” For a small, light drone, these are completely ordinary.
The body isn't visible. In the dark, only the LEDs are visible, not the body of the drone. Three or four lights can look like the corners of a dark triangle or rectangle.
We don't know how close it is. A small drone hovering 50 meters away and a large object kilometers away look like the same size of light. If we think the drone is far away, we also overestimate its size and speed.
The formations. A moment caught from a drone show, or several drones flying together, can easily look like “UFOs flying in formation.”

The reverse case: when everyone sees drones

During drone panics, things flip: people mistake planets, stars and airplanes for drones.

New Jersey, 2024–2025. In November and December 2024, mass drone reports came in from New Jersey and the U.S. East Coast. On December 16, the FBI, the Department of Homeland Security, the Federal Aviation Administration (FAA) and the Department of Defense wrote in a joint statement that the reports could be traced back to lawfully operated commercial, hobbyist and law enforcement drones, airplanes and helicopters, as well as misidentified stars. On January 28, 2025, the White House press secretary said that the large number of drones flying over New Jersey were flying with FAA authorization, for research and other purposes.
Europe, fall 2025. In Poland, Denmark, Germany and several other European countries, airports and airspace were temporarily closed because of real drone incidents. At the same time, the number of reports also spiked, and according to specialist websites, some of these can be traced back to a bright star, a planet or a landing airplane.

The lesson: during a real drone wave, everyone watches the sky more closely and also notices lights that were always there.

Real cases

Paterson, New Jersey, 2021. In October, a line of lights appeared over the city for at least five minutes. According to an expert at a drone company, it was probably a practice drone show whose formation got tangled because of some error. The explanation was not officially confirmed.
U.S. nuclear power plants, 2024–2026. According to documents that have been made public, 67 drone sightings were reported over 28 nuclear facilities in 17 states, whose operators were not identified. This is a good example of how an “unresolved” case is not necessarily mysterious: the observers recognized that they were seeing a drone, they just couldn't find out whose it was. Our article on the case.

How can you check?

Watch the lights. Flashing green light, colorful LEDs, hovering: drone. Red and green wingtip lights, white strobe light, steady path: airplane. A single white, non-blinking point moving in a straight line: satellite.
Listen. In a quiet place, the buzzing of a nearby drone can be heard.
Check Flightradar24. If the light was on an airplane's route, you will find it there. Drones don't appear on it.
Think about how long you saw it. If a “hovering light” stays in the same place for hours and slowly moves toward the west, it is not a drone but a planet or a bright star.
Look for an event. Drone shows are usually held on holidays, at festivals and sporting events, and they are announced in advance.
If a drone is disturbing or poses a danger, for example flying over an airport, a military facility or an event, report it to the police.

Quick identifying signs

Colorful, blinking LEDs, in the EU often a flashing green light
Hovers in place, suddenly takes off, turns
Low, close, sometimes an audible buzz
Flies for about half an hour at most
At a drone show: formations, lettering
