Bombays

Talking of bomb bays could anyone tell me how the Wellington bombay was adapted to take two torpedoes, one on top of the other, so I understand. As far as I’m aware the Wellington originally had three fore and aft bomb positions between the bomb bay beams and sox bombay doors. Would the bombay have been deep enought to carry two torpedoes one above the other.Also,how dod they manage with the Air tails on the torpedoes.
