I'd sure like to know what was fired at, hit, and detonated that plane in the video. For certain is was guided in some manner and not simply fired through an "open sight". I know the military uses larger than average RC models as target drones but that did not look to be a military operation.

I can see it now. "hey, look. we've finally been able to make a portable missle we can guide to a model plane. All we have to do now is make it a little bigger so it can go higher and hit bigger planes." Just lovely.

I'm not keen on the paintball idea either. Fun, but exceedingly stupid.
