Production. Airplane manufacture, general. Wooden wheels are attached to a P-51 ("Mustang") fighter plane so it may be moved around the ramp at the Inglewood, California plant of North American Aviation, Incorporated. When it is ready for flight tests, regular landing wheels with rubber tires will be substituted. This plant produces the battle-tested B-25 ("Billy Mitchell") bomber, used in General Doolittle's raid on Tokyo, and the P-51 ("Mustang") fighter plane, which was first brought into prominence by the British raid on Dieppe
