They did bomb a camp. There were many prisoners who were killed and it wasn’t ever tried again because there was problems with distance AND accuracy.
I agree bombing the camps, while a nice symbolic gesture, would have been a disaster.
Better to have sent in a team to take out the Camp hierarchy.....but the odds of that succeeding would have been slim to none.
Actually Sobibor was successful because for some reason the Nazis thought it was a good idea to include Red Army prisoners in the population, they were the ones who were able to pull off the operation of taking out most of the Camp bigwigs, and allowing the escape.
