Britain always stayed one jump ahead in the Electronic War, the cumulative effect of ALL bombing lead to the German defeat. - Also, the Norden bombsight was first used on 18th March 1943, and was linked to the autopilot...[ 'Look Ma, no hands...']... - I'm not an aircraft-manufacturer looking for a contract, so I don't have anything to prove; Just my extensive reading of Bomber Command's War proves to me that British thoroughness ingenuity, the old saying of ' British soft of hand, hard of heart' attitude, was what made their efforts pay-off - 'Bomber' Harris, C in C of Bomber Command wasn't into 'panacea' targets, just bit by bit, flatten them...He allowed the formation of Pathfinders, for overall accuracy, and 617 Sqn. to deliver any 'specialist accuracy'...- The 8th AF wanted to prove what the British had already found-out the hard-way, that daylight -bombing against an enemy who had Air Superiority wasn't going to work...so they embarked on their 'Strategic Air Offensive' - Meanwhile, Britain followed the 'dirty bomb-in-the-dark Nazis' when they'd given-up bombing England, and followed them back over the Channel , and returned-in-kind, times a thousand-fold, the bombing...The American Strategic Air Offensive indeed made the B-17 famous, by the blood shed trying to conduct an Offensive without first achieving Air Superiority...that wasn't achieved until much later, when a weakened Germany from two Air Forces bombing, lost Air Superiority;- to nightfighting, to combined Allied Fighters on daylight patrols, and sensible long-range escort fighters, like the Mustang [with a Merlin in it], P-38's, P-47's and Tempests....
