I'm glad to hear that the Air League award to whoever is most worthy.
When I first became interested in flying I heard about the British Womens Pilots Association. I decided not to join on priniciple because I wouldn't have liked to have seen a male equivalent. I agree that whoever puts up the money can stipulate the criteria. I just don't happen to agree with them myself!
I suppose that you could argue that this particular scholarship wouldn't otherwise exist and that it's better to have a discriminatory one than none at all.
