You are right that there are two conflicting theories of the cause of these losses. In the beginning it was thought that securing pins had become loose and the bombs exploded when hitting the spring loaded doors. This was later found unlikely, because the direction and force of impact could not explode the bombs. Therefore it was suspected that the reason was simply intense AA-fire.
For safety reasons in the future 250 kg bombs were used only with the tail detonator and use of 25 kg bombs was prohibited, Therefore I am using the original explanation of the loss.
