While officially general officers are not considered to belong to any regiment or corps (simply being "late" of their erstwhile regiment), in practice almost all the general officers to hold a Royal Flying Corps-related appointment gained their promotion to the general officer ranks in that appointment and remained in such appointments until the creation of the Royal Air Force on 1 April 1918.
Two officers took up Royal Flying Corps related appointments while holding general officer rank: David Henderson was already a brigadier-general when the Royal Flying Corps was established, and Edward Ellington was promoted to brigadier-general while serving on the General Staff of the British VIII Corps in France, prior to taking up appointment as Deputy Director-General of Military Aeronautics.
In addition to the above generals, Brigadier-General N J G Cameron was a member of the Royal Flying Corps reserve who had qualified as a military pilot.
Unlike the above generals, Cameron never held a Royal Flying Corps appointment.
[40] In late 1915 brigades started to be established in the RFC and so brigadier-generals were created.
