Mi-17 Shootdown videos wanted !!!

Does anybody have a link to videos that show Russian helicopters being show down by shoulder-launched SAM?

I remember seeing at least three videos – two of them showing a Mi-24 shotdown (one with following heroic screaming *Allah Akbar! Allah Akbar!*) and one spectacularly sharp footage of an Mi-17 being hit by SAM, having subsequently the whole cockpit section ripped off and going in a steep uncontrolled climb.

Any links are greatly appreciated..
