United States leadership believed the Norden Bombsight (pictured at right), with improved bombing accuracy, would allow the United States Army Air Corps (USAAC) to accurately bomb enemy targets.  The problem with such accuracy was the bombsight could only be used during daylight.  This meant flying into the strength of Germany’s, Italy’s and Japan’s air defenses.  Losses would be high.  The United States developed the B-17 Flying Fortress to carryout such daylight raids.  This particular bombsight is located in the nose of a B-25 Mitchell bomber.  A medium bomber that saw service in all theaters of World War II.  The B-25 is most notably remembered for the April 1942 raid on Tokyo, Japan by USAAC flyers led by Lt Colonel James Doolittle.  The raid did insignificant damage to Japan, but it provided an early war moral boost for Americans who had watched their military suffer a string of defeats.
