A resident of one of the cities of the United States posted on YouTube a video with an unusual helicopter. He himself comments on the video as follows: “Black helicopter, alien entities! Danger! Warning! The simulator creates a fake illusion in the sky!"
Of course, everyone knows that the refined American nation is prone to panic over the slightest provocation, but nonetheless, the shots are really unusual. The helicopter flies with the horizontal engine off. As if this is not a helicopter, but its imitation.
The video shows that the mysterious aircraft is located quite far from the cameraman - there are tree branches between the video camera and the object. That is, the simplest fake is excluded. Then what is it?
The comments of the English-speaking viewers to the video are one more mystical than the other. Some even recall lines from the "Revelation" of John the Theologian. Others saw a certain sign in the time interval 1:50 - 1:51. Other users, apparently living nearby, note that they have also seen such devices. And also mysterious flying lights.
Unlike mystically minded American citizens, Russian observers are more relaxed about such personnel. And they believe that this is the so-called "stroboscopic effect". Here's an example:
Modification of the Russian Mi-24 "Tikhy" helicopter. Commenting on the video, experts note that the blades of the combat vehicle rotate so quickly that it seems they do not rotate at all. Indeed, it seems. A helicopter with such a system becomes almost inaudible during flight.
