if the 5" guns are killed, or aren't manned, with a formation of JU88's you can get through about 15% of the time with 1 drone still flyable.
85% of the time though you will not RTB as radiator will be hit on at least 1 of the engines, and maintaining alt in a ju88 with only 1 engine is not possible, let alone missing ailerons or elevators and such.
like i mentioned in the first post, sadly, you will not survive most sucessful torpedo attacks.
if you do survive, you fired too early, and the fish didnt make it there, or mis aimed.
