:PBS, The Bomber Harris tidbit is about the only thing I'm aware of about knowledge of Ultra by commanders in the air war. I'd love to hear what Curtis Lemay thought of it all, if he was informed. A man with his own Strangelovian vision; consider his advice at high levels during the Cuban Missile Crisis. I agree it and similar stuff ought to added somehow to the article, but have no time to do it myself. May I suggest that you do so? You know, be bold! If you get something off kilter, someone will eventually correct that claim, section, paragraph.
