Honestly i just get lined up, calibrate and hit my targets (hangers,ord, or dar not just little stuff like guns) and what is it with this capped field crap? all it takes is one dive bomber and for you to take off at the wrong time to get vulched and some people just preffer to fly bombers like Il2's instead of fighters.
I'm willing to bet you die most of the time. A dive bomber, never happened to me before, and I've been playing this game for a long time. IL-2's are not true bombers, i repeat, not true bombers.
Lets not mention you most likely go after bases that aren't even being targeted by your friendlies (thus likely chance no enemy fighters are around, so you get owned by FLAK), who probably need the help to capture the base.
