These are definitely unidentified flying objects, but whether they are craft piloted (poorly, I suppose) by alien beings is yet to be known and probably won’t be. When Ana Zhmaeva, the Russian student who captured the footage above St. Petersburg, turned the video over to police (thinking she’d witness two planes collide) they were unable to find any record of plane accidents in the area. Incidentally, there was an air show going on in the area that day but air traffic controlers confirmed there were no incidents or accidents.
Drones? Meteors? Alien craft? Totally fake CGI hoax? What do you think?
