Arriving at Ridgewell Air Base in Cambrideshire in July 1943, at a time when the loss rate for bomber crews was at its highest during the war, John Comer miraculously survived his prescribed quota of 25 missions before being allowed to return to his native shores. With the aid of his log books, he recreates the extraordinary tension-packed existence of those six months. The surreal life at the air base, the constant danger, discomfort and wafer-thin escapes of the missions themselves, including some on which only 1 in 12 aircraft returned, and the fluctuating emotions.
