The only time I waste a tater on a plane that's already dead is if SunsFan or Dano are the ones who did the initial damage, otherwise they are just to precious to waste. But earlier today I was popping vulchers with a Wirb and took the tail off a jug and what was left of him was fluttering straight down on top of me and when he was about 300yds off I just held down the trigger until he disappeared.
