The ladies I fly with are all indistinguishable from their male colleagues as far as flying goes.
More importantly ALL of them are against a quota for women in ANY field.
If Mr Joyce wants 50% female pilots great. On the same day he brings in that dream I expect to see 50% male cabin crew and 50% female engineers, tug drivers, baggage handlers. Oh and 50% women on the Qantas board and 50% men at check in desks.
If 50% is desirable for parliament and the flight deck then balance it up everywhere!
