Een B-25 Mitchell bommenwerper. 'U.S. Ground crewmen clean plane's cannon. Members of a ground crew, at a U.S. airfield somewhere in the Pacific, ram home a cleaning rod in the barrel of a 75-mm. cannon mounted in the nose of a U.S. B-25 Mitchell bomber just below a pair of machine guns covered with cases from 75-mm. shells. The Mitchell is about to take off on a mission against Japanese installations in the Marshall Islands of the Central Pacific.'
