Chug, I posted the 400 yard CEP figure. This was in our 540 on 35 Sqn when they were a Pathfinder sqn so is completely accurate and unbiased, same as the sqn that sank the Tirpitz.
For the uninformed, the CEP is the radius in which HALF of the bombs separately aimed at the target landed. So for 100 that landed within 400 yards 100 could have landed anywhere in Germany or beyond!
