I was watching the movie "Air Force" (1943) and a short scene was devoted to the procedure for the bombadier to destroy the bombsight lest it be captured by the Japanese. I'm aware that in actual practise the Norden bombsight did not live up to the hype. Given the supposed security measures to protect the bombsight and prevent its capture, surely at least one must have been recovered mostly intact from a crashed bomber/overrun airfield and evaluated by the Germans (or Italians or Japanese for that matter).
Were any Axis technical reports or evaluations/comparisons of the Norden bombsight recovered after the war? I'd find it ironic to learn that despite all the security, the Norden was found to be no better than what the Axis was already using.
When I was single, I had three theories on raising children. Now I have three children and no theories.
