Well some people can never be pilots due to physical disability.. So your question is a little bit vague.
However in answer to your question, I would have been the first to volunteer. However they would have had to quit using Green flares as OK to land and Red flares as in... well no wheels, go around, the tea is not brewed yet.
Also I would not have known if I was bleeding or I had defacated myself!!!
Not everybody can be a pilot.. true in 1940. True now.
