I am a little confused about the workings of the S.B.C.'s used for incendiaries : did the S.B.C. stay in the bomb bay and return with the aircraft to be reused after its load had been dropped? Or did the SBC and its load fall from the aircraft and somehow release its load of 4lb or 30 lb incendiaries? If so, how were they released from the SBC after they left the aircraft?
I have tried to find clarification online and in my books, but no luck, so asking for some help...
Many thanks as always,
Clint
