Carrier-based naval aviation term "Clara"
I'm trying to find definitive proof and official derivation of the navy pilot's call to the LSO (Landing Signal Officer) when he does not visually acquire the meatball at the designated distance aft of the ship. This term, transmitted by radio from the pilot to the LSO, is "clara". Some of us USN pilots assume this term "clara" is an abbreviation / corruption of the word "clarification". Surely the term is of British origin and perhaps someone of the stature of Captain Eric Brown would surely know the answer. Does anyone know the best place to search for this answer?
