Am i naive to think that as long as the bomber aircraft pulls positive G at time of bomb drop, the bombs would come out of the racks? I know from John Comer's book "Combat Crew", that even the G model B-17 would occasionally have problems with bombs getting stuck in the racks, do you think diving angle would make the bombs get stuck?
As far as i know, the Ju-88 design was adapted to make it a dive bomber during the prototype stage, there wasn't a production model and then they suddenly thought "we should make this a dive bomber!".
I think it would be great if the limits on dive angle were placed on the allied 'heavies', because i think it would mean that the JU88 would rightfully take it's place as a great aircraft in AH, rather than suicide torp dropper as we have now. I think the 88 is underutilised.
