The point I was trying to make is that, without more data, simply implementing a game mechanism like "At more than 15° from level, you can't drop your bombs" ignores the variation in the design between different bombers that affects the conditions under which bombs can be released. I strongly oppose the idea of implementing restrictions on what you can do with an aircraft based on what the pilots didn't do as opposed to what they couldn't do with the plane.
We have game limits on which plane you fly, driven by an artificial mechanism intended to keep historically-rare planes rare -- but once you have the plane, there are no controls on what you do with it. If you're going to impose restrictions on how people use the planes based on what the real-world pilots did or didn't do, then you should enforce strict separation of the plane nationalities and who you can engage -- after all, FW-190s didn't fly escort for Il-2s being attacked by P-51s...
Implementing restrictions like that on aircraft is suitable for the Mission Theater, where the intent is to create a simulation of air combat during WWII, but as people have pointed out again and again, AH in the main arena is a game; the flight and damage models may be simulations of reality, but the MA itself is gamey as all hell.
If the bomb shackles on a Lancaster won't release properly if the G force on the bombs isn't within, say, 30° of perpendicular to the bomb bay, then that's a genuine mechanical limitation on how you can be maneuvering the plane when you try to drop. Changing the game so that you can't drop bombs from a Lancaster if it's more than 15° from level flight because you don't want dive-bombing Lancasters is as much an "I don't like the way you want to play" whine as Lasz's squeaking about anything that lets bombers interfere with his furballing.
Whatever mechanism gets implemented should be able to pass a realism test based on what the plane could do, not on how people used it. The best example of the difference between ability and use that I can think of is Tex Johnston's barrel-rolling the Boeing Dash-80 prototype (predecessor to the 707) -- the airlines that used the 707 didn't barrel-roll the plane, but it could perform a barrel-roll.
