The RFC in general had frowned upon garish markings unlike their German counterparts. Squadrons could be identified by those in the know as many squadrons had markings on the fuselage such as lines, chevrons and zigzags. The RFC were quite obsessive about secrecy to the extent that shortly before the German March offensive, Squadrons were forced to change their markings to try and confuse the Germans.
The RNAS had a more lenient policy as is evident in the coloured stripes of 10 Squadron RNAS and the black aircraft of 8 Squadron.
Their new allies, the USA, now have their own air forces in France, and they clearly do not share the British retiscence. 94 Aero Squadron has its hat in the ring, and and the 95 Aero Squadron the kicking mule.
Today, Brigadier General Foulois, Chief if the US Air Service, established a policy authorizing creation of emblems for aviation units, and ordered all squadrons to create an official insignia to be painted on each side of an airplane fuselage:
“The squadron will design their own insignia during the period of organizational training. The design must be submitted to the Chief of Air Service, AEF, for approval. The design should be simple enough to be recognizable from a distance.”
