I've often wondered what factors lead to a particular Squadron/Jasta/Escadrille being selected to debut the latest aircraft (whatever the time period).
And I'm hoping that we can establish at least the unit (and date) that introduced any particular aircraft to operational use - even if not the reason why that unit may have been chosen.
I'll start with the ones I think I know.
July 1915; Fokker E.I; FA62
June 1916; Sopwith Triplane; 1 RNAS
August 1916; SPAD VII; N26
September 1916;Albatross D.I; Jasta 2
April 1917; Se 5; 56 Squadron
