Yarpy - the honest answer is I don't know. I know of only one 'working mum' at another base and I do not know her personal circumstances. I am however fairly certain that none of our women pilots have felt it necessary to go through the same process as the lady at BA.
We do have a number of excellent women pilots who are hardworking, professional and a pleasure to fly with. The sad reality is that in future such people are less likely to be employed in the airline industry due to the greed of an unrepresentative minority.
