The battles that were won and lost in the skies of World War II were the single most important factor in determining the outcome of the conflict. The emergence of air power as the dominant force of war marked a turning point not just in the history of flight, or the history of warfare, but in the history of mankind.

This book tells the the story of the young men and women who were thrown into the turmoil and the aircraft that carried them into battle. Using contemporary reports and photographs, including many eyewitness accounts, it is an extraordinary tale of great heroism and terrible suffering for both the pilots in the air and the civilians on the ground. Winston Churchill called it a 'memorable milestone in the march of man' as, for the first time in history, warring nations looked not across the battlefield at one another, but upwards to the skies above them.
