By bullets getting eaten I mean, they don't pass thru a friendly they get absorbed by him (they wouldn't pass thru), effectively wasting your ammunition, so there will be no 'shoulder' shooting. Also, an aware pilot can still jockey in front of a farther spraying friendly to block his shot if he so desires. The end result will be the same with less un-realism and frustration of the self-kill junk in there now, people will want to get the closest and have the best firing position or they risk wasting precious ammunition.
In a game frought with internet latency, warpers, and view restrictions that were not present in real life, being overly harsh with penalties of this nature detracts from the gaming experience, it does not enhance it. This is why AW switched from the PNG penalty to the simply absorbs bullets penalty, and never enabled mid-air collisions (not that I want AH to be like AW, but they had a valid point with regard to this issue).The person with the worst connection having a supreme advantage in a collision situation is a slightly off-topic example of why penalties of this nature don;t work over the internet very well. With this system there would be.
A) No fragging
B) No silly self-killing
C) No dis-insentive for realistic flying, just a new insentive (instead of plane damage to oneself, you lose ammunition).
