I'd like bonus damage for bombs hitting ship with armed, fueled planes on deck a la` Midway. Perhaps a randomized 0-100% of all the ordinance sitting on the deck at the time of bomb impact, plus some conversion of fuel on board into explosive impact and/or deck unusability Could even add in planes in the process of being selected in the hangar, as hangar deck secondary explosions were common on carriers with unarmored wooden decks.
