UFO. Netherlands

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:

Flying insects in photos and videos can be mistaken for UFOs.

Shooting can take place in the daytime or in the evening. When moving, the outlines of the insect can be both blurred and clear. Depending on this, dark spots or spots of bizarre shapes can be taken for UFOs. The video shows UFOs hovering in the sky, flying in a straight line or moving along a complex trajectory (for example, shooting May bugs near a tree against the background of the evening sky). Insects can be mistaken for UFOs by accident, or given out intentionally. At night, they can be highlighted by a flash.

Parallax (from the Greek. parallaxis – evasion) – change in the apparent position of any of the object relative to a background when you change viewing angle.

Due to the peculiarities of the bird's flight, it is possible to capture a moment in the photo when an ordinary bird will resemble a "classic" UFO in shape.
