What a laugh. you've clearly never spoken to a Muslim woman about hijab or abaya before. If you knew anything about the history of this region you'd know why abayas are generally black and why they wear "grids" (if in fact you are referring to a burqa- the metal face plate)
There is a vast difference between government, religious and cultural reasons for women in the Gulf to dress as they do. Perhaps you should talk to some rather than just go by what you read in the media....
What does this have to do with pilots? We have Emirati female pilots and I'm sure some of them wear abayas when off duty....
