Interesting thing. I was going for a Albatros, one of my mates was already pounding on. The Albatros burst into flames. My mate was ticked because he claimed that he flamed the machine and that I then hit the machine. I honestly don't know which of us set the machine on fire. I was wondering, can you hit a machine after it is on flames, from the fire of a squad mate and then get credit for the already buring enemy machine? This is not possible, yes or no? I owe my squadmate a kill, if this is so.
All the best,

I could be wrong but I think it credits the last person to hit the plane before the pilot dies. That gives someone several seconds after an engine has been set on fire to "steal" the kill (it takes that long for the flames to kill the pilot).

I've gotten credit in MP for kills that did not register the pilot as getting killed. Wonder why that is?
