I'd be fine with that. Since you want them to release when the bomers are OVER the target, they'd have to be going 0mph for their bomb release to be on-target.
I don't see why you would want such an idiotic thing, but whatever floats your boat.
Although in all seriousness, HELL no. Bombing is already far too easy in Aces High, release speeds are WAY above what they were in real life, and you already have guns slaved to fire simultaneously.
Now you want the bomber to fly itself, and drop its bombs automaticlly while you man the guns? toejam, might as well ask for a guided missle.
