The production of Liberty motors to date is, of course, gravely disappointing. The Government officials having the manufacture of the Liberty motor in charge have made the mistake of leading the public and the allied nations to the belief that many thousands of these motors would be completed in the Spring of 1918. The production of combat planes in the United States for use in actual warfare has thus far been a substantial failure and constitutes a most serious disappointment in our war preparations. We had no design of our own; neither did we adopt any one of the European designs until months after we entered the war. In all, five types, at one time or another, have been adopted. Two of them have been abandoned after the expenditure of much time and money. The three remaining types still left upon our program are now in the course of manufacture. Of these the largest and most powerful is the Handley-Page heavy bombing machine, designed to carry as many as six men, eight machine guns, and a heavy load of bombs, and to be driven by two Liberty motors. The testimony before your committee shows that the Signal Corps finally decided upon the manufacture of a number of sets of parts of this machine about Jan. 1, 1918. Officials of the Aviation Section of the Signal Corps testify that they do not expect the completion of the first set of parts in this country before June, 1918. Another type of combat plane, known as the De Haviland, is included in our program. This machine habitually carries two men, four machine guns, a moderate load of bombs and other apparatus and is driven by one Liberty motor. Fifteen have been completed; one has been shipped to France; the remaining fourteen have been very recently completed in this country.
