And other pyrotechnics.
IRL, if an incendiary round touched a pressed paper drop tank, a convincing flying torch would result. Likewise, fuzed ordinance slung beneath or inside an aircraft should cause...um.... aluminum dispersal.....when hit by live rounds.
Right now, AH2 models the flight model effects of exptra weight but doesnt make it appropriately dangerous to hang on to ordinance in a fight. If I land wing pings on a loaded A20, it ought not be able to dive out and drop ordinance on GV's beneath!
