If one wishes to keep the perspective in the correct balance demanded by those of political correctness who plod through the Gobi in galoshes then one must not refer to females as lady pilots without describing male pilots as gentlemen pilots. As there are really no gentlemen pilots to speak of, and certainly fewer than when I was last flying in Africa, then there are in truth no lady pilots but only women who fly, who may be called pilots, but only in order to distinguish them from ladies, who cannot fly anyway because ladies don't wear trousers.
