Training has always taken its toll, some 3000 alone dying at Bomber Command OTUs. They are rightly included in the 55,575 commemorated on the London Memorial. As Danny reminds us at post 10204:-
It is a sombre thought that the number of States-trained British Pilots (ie 'Arnold' plus BFTS) - around 7,500 +, would just about equal the pilot losses in Bomber Command (say 1/7 of the 55,000 +). This shows what an enormous boon the US Flying Training was to us, as an addition of the EFTS output.
Those trained like he in North America as pilots barely kept pace with that terrible loss rate. The cost of freedom in peace or war is prodigious, be it measured in blood or treasure. It is though a cost that we have to bear if we treasure that freedom.
