Just read through some of this thread... and.. a few errors come up.
Bombers cruised to targets. Fighters did not cruise while attacking them.
So historically while bombers were flying very slow, very lumbering -- and some cruise speeds are listed as 180 range -- fighters would be full throttle, or even WEP or diving on a target.
Closure rates in real WW2 bomber attacks were far far faster. Also defensive fire was much much less dangerous than in this game. Gunners wouldn't open up from thousands of yards out like here, and they definitely wouldn't score any hits at that range either.
I'd personally love to see ANY sources state a 262 was brought down by defensive gunfire. I don't know one way or the other, but I currently doubt it ever happened. In this game it's the most common way to kill them: nail them while they're hitting your bombers.
So no, the closure rates are NOT historic in this game, nor are the gameplay dynamics surrounding bombers and attacking bombers.
That aside, my personal opinion is that a nice 12 high attack that rotates into a near vertical 6 is a sweet shot. You run a risk of being hit from the dorsal gunner as you close in for the kill, but if you can rotate your beginning roll just a bit you can swoop in a hair off-angle and disrupt the gunner's aim. That's just one way (in a game, not in WW2) that you can do it.
