Up to this point in the war, the observers in the RNAS have worn the same Eagle badge as the pilots to distinguish them as part of the flying services.
That changed today when orders were issued for observers to wear the same single winged O badge that the RFC use.
The move was not universally popular. Cecil Latimer-Needham later recorded his opinion of the new badge:
“The brevet was a single-wing sprouting from the letter ‘O’ and this was regarded by some as rather unfortunate – a single wing, whether of bird, insect or aeroplane, is unbalanced and incapable of flight. Observers were not pilots, but this would have been apparent by an ‘()’ in a pair of wings, which in fact was the observers brevet as worn by the Royal Australian Air Force.”
