One of the most mysterious phenomena in today’s UFO. On the Internet there are a lot of documentary films from the US, especially the UFO on the American continent, whether in English, with subtitles or dubbing. Movies generally by eyewitnesses. Government and US government agencies to represent phenomena. The official explanation of the phenomenon by scientists practically non-existent. Rather, I feel like downplayed and belittle observation eyewitnesses taunted them of incompetence. In this vacuum (in) the information there is room for conspiracy theories.
The UFO phenomenon in the former Soviet Union in the past never anything not spelled. Only the late 80’s took place in our press information on alleged alien ships landing in Voronezh (1989). On YouTube is also enough films from the USA and examining UFO sightings in the former USSR (Soviet Union).
