Maybe the Royal Navy and the Army have it by way of a tradition. Maybe when the RAF is old enough to have traditions it might do something similar.
That's a dangerous argument you are peddling there. Long standing tradition infers age. And with age comes senility, talking gibberish, permanently smelling of biscuits all shortly followed by death.
Therefore to take your line of argument to its logical conclusion, the RAF are the young upstarts, coming into their time whilst the Army and Navy are due for the old peoples' home at which point the RAF then takes it rightful place.
