Really? You have a link to that in their webpage?
If chutes were never intended to be shot then they wouldn't have such a spectacular explosion effects. The explosion is far larger and more colorful than a plane's. Why would they go through so much trouble adding such a glorious effect if they didn't intend it to be seen?
The truth is you have no idea what the other guys is thinking so why sink to the silly infantile act of shooting him in his chute and rubbing in the fact you just shot him down? Why waste such an opportunity?
What is silly and infantile are those that get so offended about shooting chutes in a
game and post over the top, melodramatic posts crying about other people shooting chutes.
Yaknow Ack I know its only a cartoon game but for some reason I cant bring myself to shoot chutes for no reason. I guess Ive just seen to many people spitting out the last of their lives on dirty city sidewalks. Whatever it is I cant bring myself to do it. And I think anyone who would should part time as an "edited by me for lack of taste"
Not that I want to start another round here. 
I guess it's safe to say that you won't be bailing out around any P-38s in the near future.
ack-ack
