I’m not sure that sort of eugenics would work. Travel times, public transport etc wouldn’t be considered at all. It would even remove options for remaining staff to act as taxis, given the rules about carrying cadets in cars.
What they should do is close every squadron and then open them in what they would regard as favoured locations and see what happens.
Let’s face it there are only low 30000s cadets country wide, out of a total population of probably 7000000 - 8000000 in our age range. Would a new model have more cadets?
I wonder what the percentage of cadets was compared to eligible population 1939-45 compared to 1945-50, when a number of squadrons closed IIRC as the RAF contracted.
We should consider ourselves like mobile phone providers, do we want to cover 90% of the population OR 90% of the country, they are not the same.
