"One of the secrets of air fighting was to see the other man first. Seeing airplanes from great distances was a question of experience and training, of knowing where to look and what to look for. Experienced pilots always saw more than the newcomers, because the later were more concerned with flying than fighting. . . . The novice had little idea of the situation, because his brain was bewildered by the shock and ferocity of the fight.": Air Vice-Marshal J. E. 'Johnnie' Johnson, RAF.
