As a pilot that flew Ju88s 2 frames and escorted them 2 other frames, my main goal and intent was to represent the many strats that were bombed and/or the ships that were the main targets for most of the frames.
The bomb is falling into the explosion, not onto the tanks. The tanks are on either side and both contributing to the fire.
The idea being the explosion represents the conflict, and the bombs and tanks are adding flames to the fire.
If I wanted to show a bomber hitting tanks I'd have just put 1 tank in the middle and the bomb right over it.
I did read comments from the tankers upset at being bombed, so I understand your pain. Us bombers had our own type of pain, and the escorts still more pain. I don't think any design will please everybody, since this was quite a complicated event. SOMETHING's gonna stir up discontent, no matter what it is.
Sorry for stirring up bad memories
