These phantoms speak with human voices... able to vanish or appear at will, to pass in and out through the walls of the fuselage as though no walls were there... familiar voices, conversing and advising on my flight, discussing problems of my navigation, reassuring me, giving me messages of importance unattainable in ordinary life.
