Aircrew on a bomber in World War II experienced a cold, tiring and perilous existence. The RAF flew at night, when the human spirit is at its lowest ebb and for many it did not seem prudent to think further ahead than the target, and then hope for a safe return. Daytime raids brought the fear of defending fighters preying on the massed formations of heavily laden aircraft as they struggled over enemy territory. The ground crew saw their aircraft heave themselves into the air and their imagination filled the silent hours until they counted in the returning aircraft and saw the ravages of the enemy defences and the hazards of foul weather. This is their story.
