I witnessed a similar instance years ago when carbon arrows were the new thing at a 20 yard indoor invatitional. I was on the first line and sat down to observe the second line shoot. There was a snap, like the breaking of a pencil, then a black puff, like smoke. A carbon had shattered when released. The shooter received some carbon particles in the arm and the cables let go. I help coach JOAD FITA at our local club. Outdoor shooting requires the intermediate male archers to shoot 80 meters and the female archers out to 70 meters. With a recure bow and light draw weights of the youth shooters carbon arrows are a plus. I will only allow the carbon wrapped aluminum arrows for class just because of accidents like the one mentioned above. You can see the damage, if any, immediately with little concerns about a major breakup.[
