In the matter of the Liberty motor the same mistake was made. Instead of taking patterns and blue-prints of a good foreign motor, like the Hispano-Suiza, which was already being built in this country, and producing them in quantity, the government stopped to design a new motor—the Liberty motor—which the Aircraft Production Board evidently thought could be built in a day. This was not done—as a matter of fact, it took almost six months to complete the first production motor—whereas a good foreign motor could have been put in quantity production almost immediately, and with the failure of manufacturers of aircraft to turn out the desired number of planes, this caused a tremendous outcry from the disappointed American public, who thought 100,000 aeroplanes could be built as easily as 100,000 automobiles. This led to an aircraft investigation. Judge Hughes was appointed by President Wilson to conduct the investigation. The report failed to find any one libel to prosecution. Indeed, most of the errors were those of judgment or lack of ability. Later President Wilson pardoned those who might have been prosecuted. Another error was caused by the delay in determining on the type of aeroplane which should be built in quantity in this country. Several types were adopted and then cancelled. Finally, however, the Curtiss J. N. 4’s were adopted as the standard training-machine and the standard J. was discarded. The D. H. 4’s were turned out in large quantities by the Dayton-Wright; Curtiss produced some Bristol machines in addition to their training-machine and seaplanes. The Standard Aircraft Corporation built a few Capronis and Handley Pages, Curtiss-H-boats. Owing to a failure to adapt the Liberty engine to the Bristol fighter after three pilots lost their lives, the machine was abandoned. If the war had lasted another year these companies would have been in quantity production, and undoubtedly America would have delivered a portion of the thousands of machines which were promised on the West Front. As nearly every company which had built for the army or the navy was represented at the March, 1919, aero show, a description of the exhibits will give the best idea of the types of machines produced: AEROMARINE PLANE AND MOTOR COMPANY Model 50 flying-boat, similar to the Model 40 except that in the latter machine the cabin is closed in by a transparent hood, and it is driven by an Aeromarine 130 horse-power type-L engine. The Model 50 is a sport machine designed for pleasure flying. The upper plane has a span of 48 feet 4 inches, lower plane 37 feet 4 inches. Fully loaded the machine weighs about 2,500 pounds. Unloaded the weight is about 2,000 pounds. BOEING AEROPLANE COMPANY
