Bombers of the Second World War
The life of a second world war bomber pilot was probably the most dangerous of all the armed forces of the second world war. Less than 50% survived their tour; each tour consisted of roughly 25 operations or raids with the chances of survival for each raid being 96%. That is what the commanders always told the crew before a raid to keep up morale. But if you compound 96% over 25 times, the survival rate was closer to 50%.
