"If it's red, it's dead..."
I'm not a high scoring uber ace who can sit here and quote airspeeds and tactical situations so pardon me for being a "newbie".
I will say this though, I've only been playing again for about a week. If I'm in the middle of taking off from a field and all of a sudden I here bullets ripping through my plane I think to myself, "Hmmm.. maybe I should take off from a different field."
I fully expect any enemy, from any country, to take every oppurtunity to blow my plane into little smoking bits at any vulnerable moment. Be that take off, or landing.
No, I wouldn't go "looking for" the chance to down someone on takeoff but then again if I happen to catch someone in that situation of course I'll try to put iron on target.
Stop trying to fight with some percieved rules of engagement and realize in war no one cares if your feelings get hurt. As a matter of fact, in a war I'm not only hoping to hurt your feelings but also your ability to fight.
