Yeah, I lost one arado that way too.
Nobody seems to lose two like that.
Dinger's quick-and-dirty way to get a whole mess of Perk Points:
1. Grab a Ju88 (500 kg bombs optional)
2. Go to a front line field.
3. Take off
4. Engage enemy AC using flex guns (NOT the forward-firing gun. That one is a peashooter).
5. Bomb (if you have any) enemy GVs.
Rack 'em up.
You get 4 pps per ostwind, 4 per C-hawg, and the other stuff is pretty good too.
