It also seems that this was done on purpose behind the RT News set so that they could get caught on camera. By my estimation, this craft is two and a half times the length of the average car, or 7-8 meters long. The UFOs thickness is the same on both its front, middle and back. Therefore it is impossible that this is a plane, missile or bird.
I made the video after Lou told me about it and posted it a few minutes later. Best viewed in full screen mode and in HD settings. I will also put the full video below my video. You will need to jump to 5:58 to see the UFO.
