Just to explain German WWII aircraft bombs.
They used bombs with electronic fuzes fitted into side wells (with bombs heavier than 50 kg), nose fuzes were not used (beside in some cluster bombs). The fuzes consisted basically of two capacitors. The first would have been loaded right before dropping the bomb. When the bomb was dropped and disconnected from the circuit of the plane the first (and loaded) capacitor started to load the second capacitor (connected to the firing circuit), while this happened time went by and the aircraft moved away into a safe distance (important for low altitude attacks). When the bomb finally hit a target small spring shaped contacts in the firing circuit were moved by inertia and touched each other and closed the firing circuit.
There was an extreme wide range of fuzes for those bombs and many specialties were built in like anti disturbance and anti withdrawal features and in the end even anti ''render safe" features which were of different nature.
German aircraft bombs had a lifting lug in their nose section for lifting and mounting them into horizontal bomb bays. Of course they had lifting lugs on their sides as well to hang them horizontally.
