I have never once done, seen, or had done to me, a fighter shoot down at 1.5K.
Im really sorry a few of you had your cartoon fighters shot down, or rammed some, bombers. Perhaps if you ask nicely on 200 that they fly nice and straight and allow you to gun them all down right on their "6" they will comply. Its worth a try right?
Otherwise...Waaaa, Waaaa, Waaaa.
