Air crew knew-or could know-what the losses were. They were quickly broadcast on the BBC and printed in newspapers. The only losses omitted were those unknown to the enemy - those "operational crashes" that took place in or close to England. In any case, the losses on an operating station were only too obvious to other crews as they waited in hope for friends late to land, and then saw the quick work of the Committee of Adjustment removing the possessions of those "missing as a result of air operations" so the rooms could be occupied quickly by a new crew. Before setting off on a raid experienced crew could make a quick assessment of the key factors-length of the flight, strength of the defences, the weather, the moon, and what had happened on previous raids to that target - and make a fairly accurate guess about how many were "for the chop". So here was a strange situation where men going into battle could make a fairly accurate assessment of the likely losses.
For the men who did think about the odds they faced, a 3 per cent chance of dying on any one raid might seem reasonable. But they had to do this 30 times, and any air man could do the simple calculation that 30 times 3 per cent was 90 per cent. A 90 per cent chance of being among the missing was near enough to a certainty. If the tour was in the tough times of the Battle of Berlin, then the average loss on a raid was more like 4 per cent, and 30 times 4 per cent was 120 per cent. That was no chance. In fact, that simple multiplication does not give the odds of survival. A 3 per cent chance repeated 30 times gives a 40 per cent of completing a tour, still less than half but a lot better than 90 per cent. If the average loss rate was 5 per cent, then 21.5 per cent would complete a tour. Crews asked to fly a tour faced the probability of death, and all could know this.
The loss rate can be looked at another way. If a squadron was able to put into the air an average of twenty bombers on operating nights, and that was often the case with 460 Squadron, then over five operating nights it had to expect to lose three aircraft. In just three months (December 1943, and January and February 1944) 460 Squadron lost twenty aircraft, equal to its average fighting force. In the entire war 460 Squadron lost 1,083 aircrew. No Australian army battalion in the Second World War had anything like those battle losses, and the fighting force of a battalion is four or five times that of a bomber squadron.
The sum of all those points confirms that those in Bomber Command had a different war: it had no precedent and it will not recur. The disjunction lies between the last point and all those that go before it. A nation that asked so much of its citizens should remember them.'
