"A great deal of an aeroplane could be holed without affecting its ability to fly. Wings and fuselage could be—and often were—pierced in 50 places, missing the occupants by inches (blissfully unaware of how close it had come until they returned to base). Then the sailmaker would carefully cover each hole with a square inch of Irish linen frayed at the edges and with a brushful of dope make our aircraft 'serviceable' again within an hour." Cecil Lewis
Total airplanes produced for the United States Army
NOTE—The figures show total airplanes delivered to the US Air Service, both at home and overseas. Figures showing the actual quantity of airplanes on hand to-day (January, 1919), can not be obtained, as no figures on losses are available. It is evident that the quantity on hand is materially less than the above figures because of crashes and usual wear and tear.
