Documents Why England and not Italy? Dwyer’s list of American officers and cadets killed in training in Great Britain. A list compiled by Geoffrey James Dwyer of American officers and cadets killed while training with the R.F.C. / R.A.F. in England and Scotland (part of Dwyer’s “Report on Air Service Flying Training Department in England”). Dwyer’s table showing ratio of fatalities to flying hours by type of plane. A table compiled by Geoffrey James Dwyer showing ratio of cadet fatalities to number of flying hours in each type of plane (part of Dwyer’s “Report on Air Service Flying Training Department in England”). Dwyer’s memo on non-flying commissions. This copy of Dwyer’s memo regarding the non-flying status of some of the cadets is among the papers of Fremont Cutler Foss. “R.M.A.” stands for Reserve Military Aviator; on the test, see Hudson, Hostile Skies, pp. 29-30, and his source, Woodhouse, Textbook of Military Aeronautics (1918), p. 189. The test appears to have been a work in progress and the requirements for second Oxford detachment men were almost certainly different from those listed by Woodhouse. R.A.F. graduation requirements, taken from Foss’s R.F.C. Training Transfer Card Because Pershing’s cablegrams recommending men of the second Oxford detachment for their commissions were often dated not long after the men’s R.F.C. graduation, I for some time assumed that the recommendation for a commission was prompted by graduation. I realize now that this was a misapprehension. I have not found a document spelling out the requirements for a commission for men of the second Oxford detachment, but there was an understanding that the main requirement was that one had to have flown twenty hours solo. See, for example, Hooper, Somewhere in France, letters of December 28, 1917, and January 31 and February 14, 1918; Deetjen, diary entries for February 14 and 23, 1918; and Milnor, diary entry for January 16, 1918. List of “Casual Officers Air Service” returning to the U.S. on the Mauretania, departing Liverpool November 25, 1918. Lahm’s list of “best types of Pilots and Observers” Frank Purdy Lahm’s memo is part of “Officers who Demonstrated Exceptional Ability (List of),” which is included in Volume J.1 (Training Section, Air Service, A.E.F., France) in Gorrell.
