I hate to say it, but the aerial bombing campaign against Germany in WW2 was not terribly effective. The Germans were quick to decentralize the factories, and burning down houses did not impair the war effort much.

What did work was bombing the oil infrastructure. Germany ran out of gas.

What also worked was using the B-17 fleet as bait for the Luftwaffe. The Luftwaffe could not help but rise to defend the country, and then they were shot down by P-51s and P-47s and Spits. The goal was to erase the Luftwaffe, and it worked. (Even though German warplane production increased, the pilots were dead and irreplaceable.)
