A white flashing dot over the city of Egstgest (South Holland) was seen by an eyewitness on Monday. He writes about it like this:

Sometimes, when I look out the window in the evening, I see a white flashing dot flying back and forth. 

Sometimes I check on flightradar to see if it's a plane, but at that moment I don't see a flying plane there. It is always visible in the dark and flashes white. 

I know that some drones flash white light, but it seems a little blurry to me, which is often exactly when I'm looking. It also cannot be a satellite, because they are often smaller in size, do not blink and usually enter orbit several in a row. 

It's only been 2/3 weeks, and I have no idea what it could be. Besides, it's too far away to take a good photo.

Original news

Wit knipperende stipje boven de stad

OEGSTGEEST, ZH — Soms als ik in de avond mij raam uitkijk zie ik een wit knipperend stipje vliegen die heen en weer vliegt. Ik check soms op flightradar of het niet toevallig een vliegtuig is maar ik zie geen vliegtuig die op dat moment daar vliegt. Het is altijd in het donker en het knippert wit. Ik weet dat sommige drones wit licht knipperen maar ik vind het een beetje vaag dat het vaak precies is wanneer ik kijk. Het kan ook geen satelliet zijn want die zijn vaak kleiner, knipperen niet en gaan in een baan met meestal meerdere achter elkaar. Het is pas sinds 2/3 weken en ik heb geen idee wat het zou kunnen zijn. Het is ook te ver weg om een goede foto van te kunnen maken.



List of versions containing features matching the eyewitness descriptions or material evidence


Unmanned aerial vehicle (UAVs, also sometimes shortened as BLAH; colloquially sometimes referred to as "drone" or "drone" (from the English. drone — drone)) — aircraft without crew on Board. Created for aerial shooting, monitoring ground objects and other tasks in real time.

Distinguish UAVs for military and civil purposes.

Also they are divided into:

Balloons and balls

Balloon — aircraft (balloon), which is used for the flight gas, which is lighter than air.

Balloons - different sizes and shapes size toy, often made of latex. Is inflated with air or other gas. If the gas is lighter than air, the ball gains the ability to fly. The photo looks like a small dot. The colors and the opacity depends on the texture and color of the ball.

Airplane / Helicopter

An aircraft is heavier than air for flights in the atmosphere (and outer space (e.g. An orbital aircraft)), which uses the airframe's aerodynamic lift to keep itself in the air (when flying within the atmosphere) and the thrust of the power (propulsion) installation for maneuvering and compensating for the loss of total mechanical energy on drag. 


Versions testing, their confirmation or refutation. Additional information, notes during the study of materials

If this object appears regularly, then the version with a balloon with an LED can be excluded.
