== Consistency with Wikipedia article 'Standard Aircraft Corporation' == 

 Under 'Production' is stated "In the United States, the Boeing Airplane Corporation, Dayton-Wright Airplane Company, the Fisher Body Corporation, and the Standard Aircraft Corporation produced the DH-4 . . . " The article 'Standard Aircraft Corporation' does not mention the DH-4. According to Roberts, John, "Mitsui: Three Centuries of Japanese Business" (Tokyo: Weatherhill, 1973), Standard company preferred stock belonged in total to Mitsui, and the company was sued by the USG after the war to recover $2.5 million in overpayments. This would suggest that Standard's production of the DH-4 was significant, was properly mentioned in this article, and should be mentioned in the Standard Aircraft Corporation article.
