Technical notes
A 1918 course manual issued by the University of Illinois School of Military Aeronautics at Urbana, compiling technical notes for army flying cadets in wartime training. The pages run to columned glossaries of airframe parts, explanatory text on wing lift and drift, a synoptic weather chart with isobars and station circles, and photographic plates labelling Lewis gun components \u2014 useful for machine-part diagrams, aviation nomenclature lists, and meteorological line work.
