2K? Ho ho ho.
Nah, if you only disable the release when non-level they'll dive in to their usual 500 ft. F3 view is a crutch only, there are "other ways" ... I'm sure the duhweebs will figure 'em out.
You need to disable bomb release from anything but the bombardier view ... and even then, I know it'll be gamed (i.e. eyeball it in F3, open bay, a few seconds before it's "just right" go to bomb view, one-one-thousand, two-one-thousand, barf). Not as accurate - as just using F3 ... but have you seen how accurate these 'tards are as it is?
I don't want to make it too messy with sight calibration because that penalizes the guys who fly these planes right - they need to be able to jump to gunner positions and then return to the bomb sight and have it be as they left it.
If you allow bomb release only from the bombardier position that adds enough extra uncertainty to render such attacks much less effective. Add to that the "rack failure" due to excessive G's and suddenly you need to be very gentle in coaxing that big bird out of a dive (as well you should). Given the way these guys fly, I doubt many will be able to handle it.
