And I'll again ask the question that has already been asked 100 times -- why is the lower proportion of women in flying jobs seen as a "problem" or "puzzle" that needs to be fixed or solved? Why not any of the other roles in the industry that are dominated by one gender, as has been mentioned above?
Women should be made aware at a grass roots level that the industry is not at all discriminatory and if they're interested in a flying career to go for it. Then let the statistics fall where they may.
