World War One aviators were more than just soldiers they were the knights of the sky, and the press and public idolised the gallant young heroes. But for Stanley Woolley, commanding officer of Goshawk Squadron, the romance of chivalry in the clouds is just a myth. There are two types of men up there: victims and murderers, and the code he drums into his men bans any notion of sport or fair play. This produces better killers but, even so, Wolley believes the whole squadron will be dead within three months.
