Uh... it was burning up (both burning and exploding at points) coming through the atmosphere... its what they do. What you see going back up looks a lot like a camera light reflection because of the angle and the brightness that the fireball had achieved. I mean, the movement is an inverse direction reflection. I understand that it looks like something intercepted it, but if you compare it to the other fireballs as of late, its pretty standard... scary, but standard. The one over Argentina the other night looked very similar, but the angle was a bit different so it was quicker. I am sorry, but camera reflections like that does happen. I am much more concerned at the sheer number of these larger meteors we are seeing lately... many are complete surprises.
