Well if you do end up flying in straight line, then like you said. Keep your head on a swivel, or be sure that Jerry can't sneak up on you :P

Lol, took me a while but i've also got my first 109 kill. :)

I was "fighting" some stukas when i suddenly saw tracer rounds all around me, so i made tight turn to see there's a 109 on my tail.
Unsuccesfully tried for 5 minuten to shake him off before deciding to call in some backup.
As soon as the second Spitfire arrived the 109 breaks away and tries to escape.
Got behind him, took a few shots, and down he went... 8)

Love this game already!
