The biggest problem in writing a book along the lines you suggest might be that any potential author would spend so much time reading and cross-referencing that he or she would have little opportunity to take pen in hand! It would first be necessary to collect a large number of
Memorable Firsts by sifting through an extensive list of references. Then, when conflicting accounts of some specific event are found, further research would be needed to separate the tall tales from history.
A more promising approach to your suggested theme might be to establish a bulletin board electronic forum for WW1 Aviation Trivia. If enough members saw fit to post any interesting "first" that they happened across, a fairly substantial list might be assembled in a fairly short time, and members having conflicting accounts of a given event could argue their case in public. The only essential requirement would be that sources be identified for each initial post.
I began compiling a personal reference list of interesting firsts some time ago. My motivation was not that I intended to write anything, but was simply tired of being unable to recall where I read about some specific item. Here are a few samples, collected and merged from the books
Years of Combat by Sholto Douglas,
The Sky Their Battlefield by Trevor Henshaw, and
Recollections of an airman by Louis A. Strange:
The first R.F.C. casualties in a wartime flying accident were 2/Lt R. R. Skene and Air Mechanic R. K. Barlow of 3 Squadron, killed in a crash shortly after taking off for Netheravon
en route for France, on 12 August 1914. Skene was one of the first British flyers to execute a loop.
The first R.F.C. aircraft to land in France on the business of war was a B.E.2b flown by Lt H. D. Harvey-Kelly of 2 Squadron. The flight took off from Dover, and landed in a field near Amiens at 0820 hrs on 13 August 1914.
The first R.F.C. casualties in France were 2/Lt Copland Perry and Air Mechanic H. E. Parfitt who were killed when their B.E.8 crashed on takeoff (stalled) from Amiens on 16 August 1914.
The first R.F.C. reconnaissances over the lines were made on 19 August 1914. The pilots were Capt P. B. Joubert de la Ferté of 3 Squadron (Bleriot XI) and Lt G. W. Mapplebeck of 4 Squadron (B.E.2). The aircraft took off together at 0930 hrs, but flew separate directions thereafter.
The first British airman to be wounded in the air was the Disciplinary Sergeant-Major of 2 Squadron, D. S. Jillings, on 22 August 1914. His normal duties leaving him with some free time, Sgt Jillings was sent out as an observer, in a B.E.2 flown by 2/Lt M. W. Noel. Sgt Jillings was struck by ground fire in either the buttock or leg, depending on which source one chooses to believe. (To be inclusive, let's say the upper leg!) Happily, Sgt Jillings was able to return to his squadron by October 1914. He remained in the R.A.F after the war, ans saw service in WW2 as a Wing Commander.
