I’ve read that too, especially about the Schweinfurt raids. It turned out that the ball-bearing machinery was very sturdy and hard to kill without a direct hit. I’ve also heard that a single Strike Eagle with PGMs could do far more damage than a whole squadron of B-17s, since each bomb would be a direct or near-direct hit, instead of dozens or even hundreds of yards away. Direct hits from carpet bombing were more of an accident than a fact.
After WW II we determined that Allied bombing directly hit the target 6% of the time.
