I wholeheartily agree, and i do understand that the bombing campaighn didnt get to full speed until the middle to late part of the war. But after the way Churchhill saw the U-boat, and the fact that the factory was within range of early war bombers, you'd of thought ole Winston would of let the dogs out.
The amazing thing is that they(the allies) didnt even know of the factories existance untill 43!
