The point I was making was that the "Fortress" was unable to protect
its crews as the USAAC (and other air forces) had fondly believed
before the war, and that aerial bombardment in WWII by and large failed to
live up to the hopes and fears of the generals, at least
until Little Boy made accuracy irrelevant.

When noting that at one point 63% of bomber crews failed to complete their
tours, you could have added that towards the end of the campaign -many-
completed their tours and never even saw a German fighter.

But you didn't do that.
