I agree with the benefit of hindsight things would not have been done as they were. There was still the notion of breaking the enemy's morale through bombing where we now know the opposite is true, trauma caused to groups of people, so they have shared bad experiences, brings them closer together so they provide mutual support to each other.
The US daylight bombing was more successful at hitting vital industrial targets but at a very high cost through attrition, until long range escorts were available, especially the Mustang, which was the best fighter of WWII and by the eventual winning of air superiority. The British used wooden wonder, the Mosquito light bomber, for daylight raids where it was fast enough to allude German fighters.
617 squadron should not only be remembered for attacking the dams, but also their precision bombing techniques using Tallboy and Grandslam bombs, which were used to sink the Tirpitz, destroy U-boat pens, and vital bridges, tunnels and other targets in the run up to D-Day.
It was also a tremendous area of technological with Gee and H2S radar and evolving techniques to improve accuracy like the formation of the Pathfinder squadrons.
Until 1943 in Africa and Italy and 1944 in France, this was the only method we had to regularly attack and disrupt the enemy on a daily basis.
Personally, I think a group of people that went into battle like this night after night with a 50%+ attrition rate, deserve the utmost respect and should be remembered and honoured, regardless of any flawed tactics by politicians and their superior officers.
