Not sure about that, Fats, but they always hit where the Norden says they'll hit, wind doesn't affect them, and they don't disperse.
I'm not sure how good the Norden optics were, but could you really pick out a 40mm cannon from 30.000 feet? In that case, why did the allies bother with carpet bombing?
