What is "airlanes"

Usage examples of "airlanes".

At the moment of the contemporary metaphysician's loftiest flight, when he is most gratefully warmed by the feeling that he is far above all the ordinary airlanes and has absolutely novel concept by the tail, he is suddenly pulled up by the discovery that what is entertaining him is simply the ghost of some ancient idea that his school-master forced into him in 1887, or the mouldering corpse of a doctrine that was made official in his country during the late war, or a sort of fermentation-product, to mix the figure, of a banal heresy launched upon him recently by his wife.
