To be honest capturing all this from the ground outside of a shelter looking up directly is very dangerous thing... Finally the debris are still falling down and quite dangerous. Even debris make serious damage.Also it is amazing technology and looks cool at Youtube, it really isn't cool at all to be around when this happens... especially when you at an open space without any shelter around lying on the ground and seeing this "white puffy clouds" above your head.
Looks like CGI to me
...Especially the way how the missiles do a reversal to track the target looks fishy.
That's a key part of the Iron Dome interceptor's engagement strategy. They fly out ahead of the incoming warhead then turn into them, head on, to achieve maximum kinetic destructive potential. Come to think of it, several SAM systems use the same strategy for closing threats.
The Iron Dome are HOers? They should learn some ACM!!!
CGI, by intention looks very real. So by saying it looks like CGI you realize of course that you're saying it looks very real.
