Take a look a this...it's important.
I've seen it and based on my 26 years of dodging and observing such missles and other like ordnance I will suggest it was not any form of "weapon" I have ever seen or experienced. Doesn't mean that such does not exist just because I have not personally witnessed such a munition . It's just that most "known" surface to air and or air to air missles don't move in such a manner as seen in this video clip.
Stay Safe !
