Im sure ya all met, with that situation: Starting bomb with plane—>set the angle for bombing ,and dive toward ground—> when you feel the right point, you pull up and drop bombs…BUT you accidentaly stuck up on tree and killed yourself…(still not big deal…it happens).
First time I saw that when enemy kills their owns: e.g: ____Enemy 
player1 (Enemy FF is fun 
)
- The point is, when the BOMBS you released are destroys the target in range, and also kill friendlies, if you dies faster than bombs explode (FF boom)…Ouch!
- If you kill friendlies, if not, no matters, but the kills and XP for enemies, does not counted for you, if you dies before bombs explode and kill. Weird…
No FF at all:
If you start bombing, kill soldiers/vehicles and you don’t die before bombs are exploed, the kills and XPs are counted, and you didn’t hurt friendlies at all, even if they are within range of explosion. Hm… 
Is this for reason? Or what the purpose of it? I just wonder, and wanna ask about your Opinion, Experience and your Stories!! 
Cheers!
