Enlisted Navy Pilot wings were NOT silver, they were gold just like Naval Aviator wings. If anyone can find a reliable reference that says otherwise, please provide it. Between January 1927 and October 1929 the design of Naval Aviation Observer Wings was the same as Naval Aviator Wings except the observer wings were silver. Naval Aviation Observers were not pilots.
