The problem with women pilots is simple: they go and get pregnant, then their line is covered by their colleagues, then the girls usually come back after mat leave and do a new rating or refresher sim, then they get pregnant again.
I'm amazed airlines take on any girls of breeding age. They cost a fortune.
And these are the comments of one who has no axe to grind, as I have a goodly family of my own.
