Nuremberg raid.
jeffb,
"Blue on Blue !" There has never been a war in which this has not happened. As you say: "Shoot first and ask questions afterwards" was ever the key to survival. There was a prime RAF example very early in the war, look up: "The Battle of Barking Creek".
The Nuremberg raid must have been among the most costly of Harris's three year campaign. Yet "you can't make omelettes without breaking eggs"; there is no cost-free war; it was what we signed up for in the first place, after all.
