I don't think its that deadly. I think your only is either not taking evasive action to avoid flack, or your bellybutton is getting capped by the guys in the turrets.
But that just my opinion.
...Your mother was a hamster and your father smelt of elderberries, now go away or I shall insult you for a second time.
I wish I could dig up the video, I posted it here once before, but mediafire took the video down and I'm afraid it's gone. :/
But, flying at ~17k in P-47-d-25's going around 325 mph, *poof*, just like that, our flight lead was gone. I take formation leader as we were 4 1/2 sectors away from the nearest friendly base, continue our strike, and a sector or so away, we run into the CV firing at us... All of us were killed.
I would love to see WWII footage of a flak gunner hitting anything at 17k clocking >300mph, much less in one burst from BVR.
And Raptor, no, we're talking about AUTO ack...
