I went to RT to look at photos of the wreckage and a video is included. In the video at 1:00 a UFO streaks across the sky. It is not a spark and I
doubt if it's a missile. Take a look at this screen capture and then go view the video at rt.com...
I think it was something close to the camera, flying ash,spark, insect maybe, even Missiles dont fly that fast, you can see another one few seconds
later in the video!
