The series is based on actual events. The Times of 7 May 1946 reported:
German scientists, many of whom are leading aeronautical authorities, are coming to Britain to cooperate with British scientists in hastening the development of aero-dynamics, to solve the problems created by the jet engine … When Britain captured the air speed record of 606 m.p.h., jet engines had to be held back. They could easily have gone on at a greater speed if the development in aero-dynamics and in the structure of aeroplanes had kept pace with the progress of the jet engine. Since then the jet engine had forged ahead again and its development was going on by leaps and bounds …
… The scientists, all of whom are non-Nazis, will work at Farnborough, Hants, where they will live in a special hostel and will be waited on by German prisoners of war. They have been working in German research stations and will be paid the same salaries as they received there.
… In the disarmament of Germany … it was decided that this vital realm of research should not be left intact in Germany … America, Russia, and Britain had now agreed that so many of these scientists should go to each of the three countries to cooperate with their own scientists. About 25 would be coming to this country.
In Hitler’s Last Army I describe many of the other occupations in which German prisoners of war were engaged in Britain, both during and after the war. Many people would be astonished to learn, for example, that trusted German POWs were given the task of compiling records of Nazis who were wanted for war crimes; other detainees had the job of keeping an up-to-date index of all POWs in British camps.
